2. Description of the Related Art
[0003] A digital image capturing device such as a mobile terminal equipped with a camera (e.g., a camera phone, a smart phone, etc.), a digital camcorder and a digital camera is ever increasingly used.
[0004] Such an image capturing device typically provides a preview function. The preview function refers to a function that displays the images projected on the lens as a series of continuous images in real time so that the user can select among the images by pressing the shutter.
[0005] A technology for providing information on an object included in the preview images or an object within a predetermined distance is being developed. Such technology is called augmented reality technology. Augmented reality refers to a reality in which real-world images and information related to the real environment are mixed by inserting the information into the real environment.
[0006] Augmented reality allows users to more easily acquire information related to the real world.
[0007] A mobile terminal may be connected to a communication network to receive a variety of information. Accordingly, a control unit of the mobile terminal can identify the location of the mobile terminal to indicate information on the location of the mobile terminal.
[0008] Such information may be represented as an image or text on the display unit. When such information is displayed to be used as augmented reality, it is possible to provide more intuitive information to the user of the mobile terminal.
[0009] As the augmented reality technology is more frequently used, the augmented reality technology finds more and more applications. In particular, a technology has been introduced, which allows consumers to check in advance the arrangement of home appliances or object by placing the home appliances or object in a virtual space of an indoor space even without actually placing them. Therefore, the development of such augmented reality technology is desirable.

DETAILED DESCRIPTION
[0035] Specific structural and functional descriptions of embodiments of the invention disclosed herein are only for illustrative purposes of the embodiments of the invention. The invention may be embodied in many different forms without departing from the spirit and significant characteristics of the invention. Therefore, the embodiments of the invention are disclosed only for illustrative purposes and should not be construed as limiting the invention. That is, the invention is only defined by the scope of the claims.
[0036] It will be understood that when an element is referred to as being related to another element such as being "coupled" or "connected" to another element, it can be directly coupled or connected to the other element or intervening elements may be present therebetween. In contrast, it should be understood that when an element is referred to as being related to another element such as being "directly coupled" or "directly connected" to another element, there are no intervening elements present. Other expressions that explain the relationship between elements, such as "between," "directly between," "adjacent to," or "directly adjacent to," should be construed in the same way.
[0037] Throughout the specification, the same reference numerals will refer to the same or like parts.
[0038] It will be understood that, although the terms "first," "second," "third" etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, "a first element," "component," "region," "layer" or "section" discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.
[0039] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, "a", "an," "the," and "at least one" do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, "an element" has the same meaning as "at least one element," unless the context clearly indicates otherwise. "At least one" is not to be construed as limiting "a" or "an." "Or" means "and/or." As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms "comprises" and/or "comprising," or "includes" and/or "including" when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.
[0040] Furthermore, relative terms, such as "lower" or "bottom" and "upper" or "top," may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. The term "lower," can therefore, encompasses both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. The terms "below" or "beneath" can, therefore, encompass both an orientation of above and below.
[0041] "About" or "approximately" as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within .+-.30%, 20%, 10% or 5% of the stated value.
[0042] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
[0043] Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.
[0044] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.
[0045] FIG. 1 is a plan view showing an example of a display device proposed to a consumer by applying a method for proposing a location of a display device according to an embodiment of the present disclosure.
[0046] Referring to FIG. 1, the display device proposed to a consumer by applying the method for proposing a location of a display device according to the embodiment of the present disclosure may have a quadrangular shape when viewed from the top (i.e., in a plan view). It is, however, to be understood that the present disclosure is not limited thereto. The shape of the display device when viewed from the top may be a square, a circle, an ellipse, or other polygons in another embodiment. In the following description, it is assumed that the display device has a rectangular shape when viewed from the top.
[0047] The display device includes a display panel that provides a display screen. Examples of the display panel may include an inorganic light-emitting diode display panel, an organic light-emitting display panel, a quantum-dot light-emitting display panel, a plasma display panel, a field emission display panel, etc. In the following description, an inorganic light-emitting diode display panel is employed as an example of the display panel, but the present disclosure is not limited thereto. Any other display panel may be employed as long as the technical idea of the present disclosure can be equally applied.
[0048] The display device may include a display area DA and a non-display area NDA. The display area DA may include a plurality of pixels PX to display images. The plurality of pixels PX may be arranged in a matrix pattern. The non-display area NDA may be disposed around the display area DA to surround the display area DA, and may display no image. The non-display area NDA may completely surround the display area DA when viewed from the top. The display area DA may be referred to as an active area, while the non-display area NDA may also be referred to as an inactive area. The display area DA may generally occupy the center of the display.
[0049] The non-display area NDA may be located on one side and the opposite side in a first direction DR1, and one side and the opposite side in a second direction DR2. It is, however, to be understood that the present disclosure is not limited thereto. The non-display area NDA may be located only on one side and the opposite side in the first direction DR1, or only on one side and the opposite side in the second direction DR2 in another embodiment. Lines or circuit drivers included in the display may be disposed or external devices may be mounted in the non-display area NDA on each of the side.
[0050] Referring to the enlarged view of FIG. 1, each of the plurality of pixels PX of the display device may include light-emitting areas LA1, LA2 and LA3 defined by a pixel-defining layer, and may emit light having a predetermined peak wavelength through the light-emitting areas LA1, LA2 and LA3. For example, the display area DA of the display may include first to third light-emitting areas LA1, LA2 and LA3. In each of the first to third light-emitting areas LA1, LA2 and LA3, light generated by light-emitting elements of the display device exits out of the display device.
[0051] The first to third light-emitting areas LA1, LA2 and LA3 may emit light having predetermined peak wavelengths to the outside of the display. The first light-emitting area LA1 may emit light of a first color, the second light-emitting area LA2 may emit light of a second color, and the third light-emitting area LA3 may emit light of a third color. For example, the light of the first color may be red light having a peak wavelength in the range of 610 to 650 nanometers (nm), the light of the second color may be green light having a peak wavelength in the range of 510 to 550 nm, and the light of the third color may be blue light having a peak wavelength in the range of 440 to 480 nm. It is, however, to be understood that the present disclosure is not limited thereto.
[0052] The display area DA of the display device may include light-blocking areas BA located between the adjacent ones of the light-emitting areas LA1, LA2 and LA3. For example, the light-blocking areas BA between the light-emitting areas may surround the first light-emitting area LA1 to the third light-emitting area LA3.
[0053] FIG. 2 is a cross-sectional view taken along line I-I' of the enlarged view of FIG. 1.
[0054] Referring to FIG. 2, the display device of FIG. 1 may include a substrate SUB disposed across the display area DA and the non-display area NDA, a display element layer DEP on the substrate SUB disposed in the display area DA, and an encapsulation member ENC disposed across the display area DA and the non-display area NDA to encapsulate the display element layer DEP.

[0057] The buffer layer 120 may be disposed on the substrate 100. The buffer layer BF may be formed of an inorganic film that can prevent the permeation of air or moisture.
[0058] The thin film transistor layer TFTL may include a thin film transistor TFT, a gate insulator GI, an interlayer dielectric layer ILD, a first passivation layer PAS1, and a first planarization layer OC1.
[0059] The thin-film transistor TFT may be disposed on the buffer layer BF, and may form a pixel circuit of each of a plurality of pixels.
[0060] The semiconductor layer ACT may be disposed on the buffer layer BF. The semiconductor layer ACT may overlap the gate electrode GE, the source electrode SE and the drain electrode DE in a plan view. The semiconductor layer ACT may be in direct contact with the source electrode SE and the drain electrode DE, and may face the gate electrode GE with the gate insulator GI therebetween.
[0061] The gate electrode GE may be disposed on the gate insulator GI. The gate electrode GE may overlap the semiconductor layer ACT with the gate insulator GI interposed therebetween in a plan view.
[0062] The source electrode SE and the drain electrode DE are disposed on the interlayer dielectric layer ILD such that they are spaced apart from each other. The source electrode SE may be in contact with one end of the semiconductor layer ACT through a contact hole formed in the gate insulator GI and the interlayer dielectric layer ILD. The drain electrode DE may be in contact with the other end of the semiconductor layer ACT through a contact hole formed in the gate insulator GI and the interlayer dielectric layer ILD. The drain electrode DE may be connected to a first electrode AE of a light-emitting element EL through a contact hole formed in the first passivation layer PAS1 and the first planarization layer OC1.
[0063] The gate insulator GI may be disposed on the semiconductor layer ACT. For example, the gate insulator GI may be disposed on the semiconductor layer ACT and the buffer layer BF, and may insulate the semiconductor layer ACT from the gate electrode GE. The gate insulator GI may include a contact hole penetrating through the source electrode SE and a contact hole penetrating through the drain electrode DE.
[0064] The interlayer dielectric layer ILD may be disposed over the gate electrode GE. For example, the interlayer dielectric layer ILD may include the contact hole via which the source electrode SE penetrates, and the contact hole via which the drain electrode DE penetrates.
[0065] The first passivation layer PAS1 may be disposed above the thin-film transistor TFT to protect the thin-film transistor TFT. For example, the first passivation layer PAS1 may include a contact hole through which the first electrode AE passes.
[0066] The first planarization layer OC1 may be disposed on the first passivation layer PAS1 to provide a flat surface over the thin-film transistor TFT. For example, the first planarization layer OC1 may include a contact hole through which the first electrode AE of the light-emitting element EL passes.
[0067] The emission material layer EML may include a light-emitting element EL, a first bank BNK1, a second bank BNK2, a first element insulating layer QPAS1, and a second passivation layer PAS2.
[0068] The light-emitting element EL may be disposed on the thin-film transistor TFT. The light-emitting element EL may include a first electrode AE, a second electrode CE, and a light-emitting diode ED.
[0069] The first electrode AE may be disposed on the first planarization layer OC1. For example, the first electrode AE may be disposed over the first bank BNK1 disposed on the first planarization layer OC1 to cover the first bank BNK1. The first electrode AE may be disposed to overlap one of the first to third light-emitting areas LA1, LA2 and LA3 defined by the second bank BNK2 in a plan view. The first electrode AE may be connected to the drain electrode DE of the thin-film transistor TFT.
[0070] The second electrode CE may be disposed on the first planarization layer OC1. For example, the second electrode CE may be disposed over the first bank BNK1 disposed on the first planarization layer OC1 to cover the first bank BNK1. The second electrode CE may be disposed to overlap one of the first to third light-emitting areas LA1, LA2 and LA3 defined by the second bank BNK2 in a plan view. For example, the second electrode CE may receive a common voltage applied to all pixels.
[0071] The first element insulating layer QPAS1 may cover a part of the first electrode AE and a part of the second electrode CE adjacent to each other and may insulate the first and second electrodes AE and CE from each other.
[0072] The light-emitting diode ED may be disposed between the first electrode AE and the second electrode CE above the first planarization layer OC1. The light-emitting diode ED may be disposed on the first element insulating layer QPAS1. One end of the light-emitting diode ED may be connected to the first electrode AE, and the other end of the light-emitting diode ED may be connected to the second electrode CE. For example, the plurality of light emitting elements ED may include active layers having the same material so that they may emit light of the same wavelength or light of the same color. The lights emitted from the first to third light-emitting areas LA1, LA2 and LA3, respectively, may have the same color. For example, the plurality of light-emitting diodes ED may emit light of the third color or blue light having a peak wavelength in the range of 440 nm to 480 nm.
[0073] The second bank BNK2 may be disposed on the first planarization layer OC1 to define first to third light-emitting areas LA1, LA, and LA3. For example, the second bank BNK2 may surround each of the first to third light-emitting areas LA1, LA2 and LA3. It is, however, to be understood that the present disclosure is not limited thereto. The second bank BNK2 may be disposed in each of the light-blocking areas BA in another embodiment.
[0074] The second passivation layer PAS2 may be disposed on the plurality of light-emitting elements EL and the second bank BNK2. The second passivation layer PAS2 may cover the plurality of light-emitting elements EL to protect the plurality of light-emitting elements EL.
[0075] The display may further include the second planarization layer OC2, the first capping layer CAP1, the first light-blocking member BK1, the first wavelength converting unit WLC1, the second wavelength converting unit WLC2, the light-transmitting unit LTU, the second capping layer CAP2, the third planarization layer OC3, the second light-blocking member BK2, the first to third color filters CF1, CF2 and CF3, the third passivation layer PAS3, and the encapsulation member ENC.
[0076] The second planarization layer OC2 may be disposed on the emission material layer EML to provide a flat surface over the emission material layer EML. The second planarization layer OC2 may include an organic material.
[0077] The first capping layer CAP1 may be disposed on the second planarization layer OC2. The first capping layer CAP1 may seal the lower surfaces of the first and second wavelength converting units WLC1 and WLC2 and the light-transmitting unit LTU. The first capping layer CAP1 may include an inorganic material.
[0078] The first light-blocking member BK1 may be disposed on the first capping layer CAP1 in the light-blocking area BA. The first light-blocking member BK1 may overlap the second bank BNK2 in the thickness direction (i.e., third direction DR3) in a plan view. The first light-blocking member BK1 can block the transmission of light.
[0079] The first light-blocking member BK1 may include an organic light-blocking material and a liquid repellent component.
[0080] Since the first light-blocking member BK1 includes the liquid repellent component, the first and second wavelength converting units WLC1 and WLC2 and the light-transmitting unit LTU may be separated so that they can correspond to the respective light-emitting areas LA.
[0081] The first wavelength converting unit WLC1 may be disposed in the first emission area LA1 on the first capping layer CAP1. The first wavelength converter WLC1 may be surrounded by the first light blocking member BK1. The first wavelength-converting unit WLC1 may include a first base resin BS1, first scatterers SCT1, and first wavelength shifters WLS1.
[0082] The first base resin BS1 may include a material having a relatively high light transmittance. The first base resin BS1 may be made of a transparent organic material. For example, the first base resin BS1 may include at least one organic material among an epoxy resin, an acrylic resin, a cardo resin, and an imide resin.
[0083] The first scatterers SCT1 may have a refractive index different from that of the first base resin BS1 and may form an optical interface with the first base resin BS1.
[0084] The first wavelength shifters WLS1 may convert or shift the peak wavelength of the incident light to a first peak wavelength. For example, the first wavelength shifters WLS1 may convert blue light provided from the display into red light having a single peak wavelength in the range of 610 nm to 650 nm, and output the light. The first wavelength shifters WLS1 may be quantum dots, quantum rods, or phosphor. The quantum dots may be particulate matter that emits a color as electrons transition from the conduction band to the valence band.
[0085] The light output from the first wavelength shifters WLS1 may have a full width of half maximum ("FWHM") of the emission wavelength spectrum of 45 nm or less, 40 nm or less, or 30 nm or less. Accordingly, the color purity and color gamut of the colors displayed by the display can be further improved.
[0086] A part of the blue light emitted from the emission material layer EML may pass through the first wavelength-converting unit WLC1 without being converted into red light by the first wavelength shifters WLS1. When such blue light is incident on the first color filter CF1, it can be blocked by the first color filter CF1. On the other hand, red light converted by the first wavelength-converting unit WLC1 may pass through the first color filter CF1 to exit to the outside. Accordingly, the first light-emitting area LA1 may emit red light.
[0087] The second wavelength-converting unit WLC2 may be disposed in the second light-emitting area LA2 on the first capping layer CAP1. The second wavelength-converting unit WLC2 may be surrounded by the first light-blocking member BK1. The second wavelength-converting unit WLC2 may include a second base resin BS2, second scatterers SCT2, and second wavelength shifters WLS2.
[0088] The second base resin BS2 may include a material having a relatively high light transmittance. The second base resin BS2 may be made of a transparent organic material.
[0089] The second scatterers SCT2 may have a refractive index different from that of the second base resin BS2 and may form an optical interface with the second base resin BS2. For example, the second scatterers SCT2 may include a light scattering material or light scattering particles that scatter at least a part of transmitted light.
[0090] The second wavelength shifters WLS2 may convert or shift the peak wavelength of the incident light to a second peak wavelength that is different from the first peak wavelength of the first wavelength shifters WLS1. For example, the second wavelength shifters WLS2 may convert blue light provided from the display into green light having a single peak wavelength in the range of 510 nm to 550 nm, and output the light. The second wavelength shifters WLS2 may be quantum dots, quantum rods, or phosphor. The second wavelength shifters WLS2 may include the above-listed materials of the first wavelength shifters WLS1.
[0091] The light-transmitting unit LTU may be disposed in the third light-emitting area LA3 on the first capping layer CAP1. The light-transmitting unit LTU may be surrounded by the first light-blocking member BK1. The light-transmitting unit LTU may transmit the incident light without converting its peak wavelength. The light-transmitting unit LTU may include a third base resin BS3 and third scatterers SCT3.
[0092] The third base resin BS3 may include a material having a relatively high light transmittance. The third base resin BS3 may be made of a transparent organic material.
[0093] The third scatterers SCT3 may have a refractive index different from that of the third base resin BS3 and may form an optical interface with the third base resin BS3. For example, the third scatterers SCT3 may include a light scattering material or light scattering particles that scatter at least a part of transmitted light.
[0094] The first and second wavelength converting units WLC1 and WLC2 and the light-transmitting unit LTU are disposed on the emission material layer EML through the second planarization layer OC2 and the first capping layer CAP1. Therefore, the display device may not require a separate substrate for the first and second wavelength converting units WLC1 and WLC2 and the light-transmitting unit LTU.
[0095] The second capping layer CAP2 may cover the first and second wavelength converting units WLC1 and WLC2, the light-transmitting unit LTU, and the first light-blocking member BK1.
[0096] The third planarization layer OC3 may be disposed on the second capping layer CAP2 to provide the flat top surfaces of the first and second wavelength converting units WLC1 and WLC2 and the light-transmitting part LTU. The third planarization layer OC3 may include an organic material.
[0097] The second light-blocking member BK2 may be disposed on the third planarization layer OC3 in the light-blocking area BA. The second light-blocking member BK2 may overlap the first light-blocking member BK1 or the second bank BNK2 in the thickness direction in a plan view. The second light-blocking member BK2 can block the transmission of light.
[0098] The first color filter CF1 may be disposed in the first light-emitting area LA1 on the third planarization layer OC3. The first color filter CF1 may be surrounded by the second light blocking member BK2. The first color filter CF1 may overlap the first wavelength-converting unit WLC1 in the thickness direction in a plan view. The first color filter CF1 may selectively transmit light of the first color (e.g., red light) and may block and absorb light of the second color (e.g., green light) and light of the third color (e.g., blue light).
[0099] The second color filter CF2 may be disposed on the third planarization layer OC3 in the second light-emitting area LA2. The second color filter CF2 may be surrounded by the second light-blocking member BK2. The second color filter CF2 may overlap the second wavelength-converting unit WLC2 in the thickness direction in a plan view. The second color filter CF2 may selectively transmit light of the second color (e.g., green light) and may block and absorb light of the first color (e.g., red light) and light of the third color (e.g., blue light).
[0100] The third color filter CF3 may be disposed in the third light-emitting area LA3 on the third planarization layer OC3. The third color filter CF3 may be surrounded by the second light-blocking member BK2. The third color filter CF3 may overlap the light-transmitting unit LTU in the thickness direction in a plan view. The third color filter CF3 may selectively transmit light of the third color (e.g., blue light) and may block and absorb light of the first color (e.g., red light) and light of the second color (e.g., green light).
[0101] The first to third color filters CF1, CF2 and CF3 may absorb a part of the light introduced from the outside of the display to reduce reflection of external light. Accordingly, the first to third color filters CF1, CF2 and CF3 can prevent color distortion due to reflection of external light.
[0102] The third passivation layer PAS3 may cover the first to third color filters CF1, CF2 and CF3. The third passivation layer PAS3 can protect the first to third color filters CF1, CF2 and CF3.
[0103] The encapsulation member ENC may be disposed on the third passivation layer PAS3. For example, the encapsulation member ENC may include at least one inorganic layer to prevent permeation of oxygen or moisture. In addition, the encapsulation member ENC may include at least one organic layer to protect the display from particles such as dust.

The checking of the light reflection image S51b may be carried out by irradiating the light paths checked in the checking of the light paths S51a to the display device when the screen of the display device is turned off.
[0133] Subsequently, referring to FIGS. 10, 11 and 14, the determining of the reflection characteristics S51 may include outputting an image on the screen of the display device (step S51c).
