Abstract

A display method for a display device is provided. The display method comprises activating a Head Mounted Theater (HMT) mode, the HMT mode displaying two images which are substantially same each other on first and second areas respectively, separated from each other, in a display area of the display device; and adjusting a display time, for displaying a black screen in the first and second areas, of a unit frame time when the HMT mode is activated.

Background

Recently, various electronic devices of a form directly wearable on the human body are being developed. These devices are commonly called wearable electronic devices. Examples of the wearable electronic devices can include a head-mounted display, smart glasses, a smart watch or wristband, a contact lens type device, a ring type device, a shoe type device, a clothes type device, a glove type device, etc., and have various forms being attachable to or detachable from a part of the human body or clothes. The wearable electronic devices are directly wearable on the human body to enhance their portability and user’s accessibility.

One example of the wearable electronic devices is a device mountable on a user’s head. Such a device can be, for example, called a Head-Mounted Display or Head-Mounted Device (HMD).

Summary

One example embodiment of the present disclosure may enhance a picture quality of a display device (e.g., a smartphone) mounted on a head-mounted device.

According to an embodiment of the present disclosure, a display method for a display device is provided, the method comprising activating a Head Mounted Theater (HMT) mode, the HMT mode displaying two images which are substantially same each other on first and second areas respectively, separated from each other, in a display area of the display device, and adjusting a display time, for displaying a black screen in the first and second areas, of a unit frame time when the HMT mode is activated.

According to an embodiment of the present disclosure, a display method for a display device including an Organic Light Emitting Diode (OLED) is provided, the display method comprising activating a Head Mounted Theater (HMT) mode, the HMT mode display an image on first and second area, separated from each other, in a display area of the display device, and increasing a driving clock speed of an Organic Light Emitting Diode (OLED) circuit for driving the OLED in the HMT mode.

According to an embodiment of the present disclosure, a display device is provides, the display device comprising a controller configured to activate a Head Mounted Theater (HMT) mode, the HMT mode displaying two images which are substantially same each other on first and second areas respectively, separated from each other, in a display area of the display device, and adjust a display time, for displaying a black screen in the first and second areas, of a unit frame time when the HMT mode is activated.

According to an embodiment of the present disclosure, a display device is provided, the display device comprising an Organic Light Emitting Diode (OLED), an Organic Light Emitting Diode (OLED) circuit for driving the OLED, and a controller configured to activate a Head Mounted Theater (HMT) mode, the HMT mode display an image on first and second area, separated from each other, in a display area of the display device, and increase a driving clock speed of the OLED circuit in the HMT mode.
