Description
CROSS-REFERENCE TO RELATED APPLICATION(S)
This application is a continuation application, claiming priority under § 365(c), of an International application No. PCT/KR2023/010746, filed on Jul. 25, 2023, which is based on and claims the benefit of a Korean patent application number 10-2022-0091650, filed on Jul. 25, 2022, in the Korean Intellectual Property Office, and of a Korean patent application number 10-2022-0113020, filed on Sep. 6, 2022, in the Korean Intellectual Property Office, the disclosure of each of which is incorporated by reference herein in its entirety.
BACKGROUND
1. Field
The disclosure relates to a wearable electronic device including a lens barrel.
2. Description of Related Art
A wearable electronic device may include augmented reality (AR) glasses or smart glasses in the form of eyeglasses that implement various content on a transparent glass member (e.g., lenses).
The wearable electronic device may be configured such that a plurality of rims (e.g., eyeglass frames) and temples (e.g., eyeglass arms) are connected via hinges, and the temples are folded or unfolded relative to the rims.
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
SUMMARY
A wearable electronic device may implement augmented reality by projecting image information from a display onto a transparent glass (e.g., an optical unit) through which external reality is visually recognized. The display may need to be maintained at high brightness in order to deliver the image information more clearly to a user. As a current flowing through a wire of the display increases to implement high brightness of the display, a voltage drop across wire resistance may increase. In this case, considering the voltage drop value, the power consumption of the display may increase as the driving voltage of the display increases.
Meanwhile, when implementing the high brightness of the display, heat may be generated in the display panel. The heat generated in the panel of the display may reduce the driving efficiency of the display panel. Accordingly, the display may require higher driving power to maintain the high brightness, which may result in an increase in heat generation of the display.
Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide a structure that implements and maintains high brightness in the display while reducing power consumption and heat generation of the display.
Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.
In accordance with an aspect of the disclosure, a wearable electronic device is provided. The wearable electronic device includes a housing including at least one opening, an optical unit positioned in the at least one opening, a display module configured to project, on the optical unit, image information, a lens barrel including a lens unit disposed to face the display module so as to guide, to the optical unit, the image information generated from the display module, wherein the lens barrel is disposed between the optical unit and the display module, and a conductive member disposed on one surface of the lens barrel to be electrically connected to a power wire of the display module.
In accordance with another aspect of the disclosure, a wearable electronic device is provided. The wearable electronic device includes a housing including at least one opening, an optical unit positioned in the at least one opening, a display module configured to project, on the optical unit, image information, and a lens barrel disposed between the display module and the optical unit, the lens barrel including a lens unit disposed to face the display module and configured to guide the image information generated by the display module to the optical unit, and at least one hole formed on one surface of the lens barrel.

In an embodiment of the disclosure, referring to FIG. 6 which will be described below, the lens barrel 300 may be disposed on the first display module 241 to include a display area (active area) 410 where an image is displayed on the screen of the first display module 241. For example, the lens barrel 300 may be disposed on the substrate 400 of the first display module 241 to surround the display area 410. In an embodiment of the disclosure, the substrate 400 of the first display module 241 may be a bendable flexible printed circuit board (FPCB).
In an embodiment of the disclosure, the lens barrel 300 may be made of a material capable of ensuring a predetermined level of rigidity or higher. In an embodiment of the disclosure, the lens barrel 300 may be made of a polymer material (e.g., PC). In some embodiments of the disclosure, the lens barrel 300 may be made of a metal material. In this case, the lens barrel 300 made of a metal material may diffuse the heat generated from the first display module 241 to the surroundings.
According to various embodiments of the disclosure, the display modules 241 and 242 may need to maintain brightness at a predetermined level or higher in order to more clearly transmit the image information projected on the optical units 251 and 252. In order to implement a predetermined level of brightness or higher in the display modules 241 and 242, the intensity of the current applied to the display modules 241 and 242 may increase. Meanwhile, when the intensity of the current flowing in a wire connected to the pixels constituting the display areas 410 of the display modules 241 and 242 increases, the amount of voltage drop generated by wire resistance may increase. In this case, the driving voltage may be increased based on the voltage drop in order to maintain the brightness of the display modules 241 and 242. Therefore, the power consumption of the display modules 241 and 242 may increase.
Meanwhile, when a high level of brightness is implemented in the display modules 241 and 242, heat may be generated from the display modules 241 and 242. The heat generated from the display modules 241 and 242 may reduce the driving efficiency of the display modules 241 and 242. In the state in which the driving efficiency is reduced, the display modules 241 and 242 may require a higher driving voltage to maintain a predetermined level of brightness or higher. In this case, as the power consumption of the display modules 241 and 242 increases, the heat generation may increase.
In addition, the first display module 241 may generate heat in the display area 410 including a plurality of pixels. As described above, the display area 410 may be covered by the lens barrel 300. In this case, the heat generated in the display area 410 may not diffuse to the outside of the lens barrel 300 and may affect the physical properties of the lens unit 310.
According to various embodiments of the disclosure, the display modules 241 and 242 may implement brightness at a predetermined level or higher. According to an embodiment of the disclosure, a structure for reducing the heat generation in the display modules 241 and 242 may be proposed. The resistance of the display modules 241 and 242 may be reduced, for example, by increasing the width of a wire connected to the display modules 241 and 242. In addition, a structure may be proposed in which heat generated from the display modules 241 and 242 can be diffused to the surroundings. This will be explained below.
FIG. 6 illustrates a cross-sectional view taken along line A-A′ in FIG. 2 and a view illustrating a state in which a conductive member is disposed on a rear surface of a lens illustrated according to an embodiment of the disclosure.
FIG. 7 is a cross-sectional view taken along line A-A′ in FIG. 2, in which a conductive member disposed on a side surface of a lens barrel is illustrated according to an embodiment of the disclosure.
Referring to FIG. 7, according to various embodiments of the disclosure, the lens barrel 300 may include a conductive member 320. In an embodiment of the disclosure, the conductive member 320 may be used as a portion of a power wire 420 for supplying power to pixels constituting the display area 410 of the first display module 241. The conductive member 320 may be disposed on one surface of the lens barrel 300 and electrically connected to the power wire 420 of the first display module 241. In an embodiment of the disclosure, the lens barrel 300 may include a front surface facing the first optical unit 251, a rear surface facing the first display module 241, a side surface that surrounds the front and rear surfaces. Referring to FIG. 6, the conductive member 320 may be disposed on the rear surface of the lens barrel 300. The lens barrel 300 may be disposed on the substrate 400 of the first display module 241 such that the conductive member 320 disposed on its rear surface is in contact with the power wire 420 disposed around the display area 410 of the first display module 241 and encloses the display area 410. In this case, as the power wire 420 of the first display module 241 is electrically connected to the conductive member 320, the same effect as physically widening the width of the power wire 420 can be achieved. As the resistance of the power wire 420 decreases, the voltage drop across the resistance may decrease. Accordingly, the compensation value for the driving voltage required to maintain the brightness of the first display module 241 may decrease. Therefore, the power consumption of the first display module 241 may decrease, and as the power consumption decreases, the heat generation of the first display module 241 may decrease.
In an embodiment of the disclosure, referring to FIG. 7, the conductive member 320 may be disposed on the side surface of the lens barrel 300. The lens barrel 300 may be disposed on the first display module 241 such that one end of the conductive member 320 disposed on its side surface is in contact with the power wire 420 disposed around the display area 410 of the first display module 241 and encloses the display area 410. In this case, as the power wire 420 of the first display module 241 is electrically connected to the conductive member 320, the same effect as physically widening the width of the power wire 420 can be achieved. As the resistance of the power wire 420 decreases, the voltage drop across the resistance decreases, and the compensation value for the driving voltage required to maintain the brightness of the first display module 241 may decrease. Therefore, the power consumption required to maintain the brightness of the first display module 241 may decrease, and as the power consumption decreases, the heat generation of the first display module 241 may decrease.
According to various embodiments of the disclosure, the conductive member 320 may have a greater width than the power wire 420 of the first display module 241. Since the power wire 420 is designed (e.g., deposited and etched) in the form of an integrated circuit on the substrate 400 of the first display module 241, there may be limitations in forming its thickness. The conductive member 320 may be formed to have a relatively thicker width than the power wire 420 of the first display module 241 as it is attached to the lens barrel 300. According to various embodiments disclosed herein, the resistance of the power wire 420 connected to the conductive member 320 may decrease as the width of the conductive member 320 increases, thereby reducing the voltage drop across the resistance. Therefore, the power consumption required to maintain the brightness of the first display module 241 may decrease, and as the power consumption decreases, the heat generation of the first display module 241 may decrease.
According to various embodiments of the disclosure, a conductive adhesive member may be disposed between the conductive member 320 and the power wire 420 of the first display module 241. The power wire 420 may be bonded to the conductive member 320 via the conductive adhesive member. In addition, the power wire 420 may be electrically connected to the conductive member 320 via the conductive adhesive member.
According to various embodiments of the disclosure, the conductive member 320 and the power wire 420 of the first display module 241 may be made of substantially the same material. In an embodiment of the disclosure, the conductive member 320 and the power wire 420 may be made of a metal material having low electrical resistance. For example, the conductive member 320 and the power wire 420 may be made of a material, such as aluminum (Al), titanium (Ti), tungsten (W), or a combination thereof.
According to various embodiments of the disclosure, the conductive member 320 may be used for various purposes other than the power wire of the first display module 241.
In an embodiment of the disclosure, the conductive member 320 may be electrically connected to a ground wire 430 of the first display module 241. In an embodiment of the disclosure, referring to FIGS. 6 and 7, the conductive member 320 may be electrically connected to the ground wire 430 rather than the power wire 420 of the first display module 241. Accordingly, the conductive member 320 may induce the flow of charges from the surroundings to the ground wire 430 having a relatively low potential.
In an embodiment of the disclosure, the conductive member 320 may be electrically connected to the first display module 241 to be used as a signal wire for the first display module 241.
For convenience of explanation, the above description was made under the assumption that the conductive member 320 of the lens barrel 300 is connected to the power wire 420 of the first display module 241. However, this may not limit the conductive member 320 to being connected only to the power wire 420. The conductive member 320 may be connected to various types of wires related to the first display module 241 to reduce the resistance of the wires. In an embodiment of the disclosure, the conductive member 320 may be connected to ground (e.g., the ground wire 430). Charges accumulated around the conductive member may move to the ground, which has a relatively low potential, through the conductive member 320.

FIG. 9 illustrates a front view of a hole of a lens barrel and a view illustrating a state in which a porous material is disposed in a hole of a lens barrel according to an embodiment of the disclosure.
FIG. 10 is a cross-sectional view taken along a A-A′ in FIG. 2, illustrating a blocking member covering a hole of a lens barrel according to an embodiment of the disclosure.
FIGS. 11A and 11B illustrate a plan view illustrating a rear surface of a lens barrel, and a view illustrating a state in which a conductive member is disposed on a rear surface of a lens barrel, and a hole is formed on a side surface of a lens barrel according to an embodiment of the disclosure.
Referring to FIGS. 8A, 8B, 8C, 9, 10, 11A, and 11B, according to various embodiments of the disclosure, the lens barrel 300 may include at least one hole 330 formed on a surface to connect the inside and the outside of the lens barrel 300. In an embodiment of the disclosure, referring to FIGS. 8A to 8C, the hole 330 may be formed on the side surface of the lens barrel 300. In an embodiment of the disclosure, referring to FIG. 8A, the hole 330 may be positioned between the lens barrel 300 and the substrate 400 of the first display module 241 and may be extended to the substrate 400. In an embodiment of the disclosure, referring to FIGS. 8B and 8C, the hole 330 may be formed on one side surface of the lens barrel 300. In an embodiment of the disclosure, one or more holes 330 may be provided. For example, multiple holes 330 may be provided. In an embodiment of the disclosure, heat generated in the display area 410 of the first display module 241 may diffuse from the inside of the lens barrel 300 to the outside of the lens barrel 300 through the hole 330. Therefore, the heat generation in the display area 410 of the first display module 241 may be reduced.
According to various embodiments of the disclosure, referring to FIG. 9, a porous material 340 may be disposed in the hole 330 of the lens barrel 300. In an embodiment of the disclosure, the porous material 340 may be a polymer material with multiple fine holes. The heat generated from the display area 410 of the first display module 241 may diffuse from the inside of the lens barrel 300 to the outside of the lens barrel 300 through the holes of the porous material 340. Therefore, the heat generation in the display area 410 of the first display module 241 may be reduced. In addition, since the holes of the porous material 340 are formed smaller than the hole 330 of the lens barrel 300, the phenomenon of foreign substances entering the inside of the lens barrel 300 through the hole 330 of the lens barrel may be alleviated.
According to various embodiments of the disclosure, referring to FIG. 10, the lens barrel 300 may include a blocking member 350 that blocks light or foreign substances from entering the hole 330. The blocking member 350 may be disposed around the hole 330 of the lens barrel 300 and face the hole 330. In an embodiment of the disclosure, the blocking member 350 may be integrated with the lens barrel 300. In some embodiments of the disclosure, the blocking member 350 may be provided separately from the lens barrel 300 and may be disposed on one surface adjacent to the hole 330 of the lens barrel 300. The blocking member 350 may block light or foreign substances outside the lens barrel 300 from entering the inside of the lens barrel 300 through the hole 330 of the lens barrel 300, thereby maintaining the quality of image information of the first display module 241 projected onto the first optical unit 251.
According to various embodiments of the disclosure, referring to FIGS. 11A and 11B, the lens barrel 300 may include a conductive member 320 and a hole 330 formed in one surface of the lens barrel 300. In an embodiment of the disclosure, referring to FIGS. 11A and 11B, the conductive member 320 may be disposed on the rear surface of the lens barrel 300 facing the first display module 241. In an embodiment of the disclosure, the number of holes 330 may be determined based on the degree of heat generated in the display modules 241 and 242. In an embodiment of the disclosure, at least one hole 330 may be formed in one surface of the lens barrel 300. In an embodiment of the disclosure, referring to FIG. 11A, the lens barrel 300 may be configured such that multiple holes 330 face each other. In some embodiments of the disclosure, the lens barrel 300 may include multiple holes 330, which are formed in adjacent surfaces, respectively. In an embodiment of the disclosure, referring to FIG. 11B, the lens barrel 300 may include a single hole 330. Therefore, the heat generated from the display modules 241 and 242 may be diffused to the outside of the lens barrel 300 through the hole 330.
According to an embodiment of the disclosure, the conductive member 320 illustrated in FIGS. 11A and 11B may be used as a portion of the power wire 420 of the first display module 241, as described above. In this case, the power wire 420 may be physically widened through the conductive member 320. Accordingly, the resistance of the power wire 420 may be reduced, thereby reducing the voltage drop across resistance. In addition, the power consumption of the first display module 241 may be reduced.
