  • Patent number: 11295675
    Abstract: The present disclosure relates to a display device and a method of compensating pixel deterioration thereof, capable of determining deterioration of pixels and sensing illuminance of a surrounding environment. The pixel deterioration compensation method compensates for deterioration of the pixels with a target compensation level varied according to illuminance. Accordingly, image quality and lifespan of the pixels is improved by mitigating or preventing acceleration of deterioration of the pixels without deteriorating image quality such as afterimages.

  • Patent number: 10734464
    Abstract: A display for virtual reality is discussed, which is capable of alleviating a screen-door effect, thereby improving its image quality. In the display for virtual reality, a light diffusion member, which diffuses light emitted from a light-transmitting area of a display panel to a light-blocking area of the display panel, is interposed between the display panel and an optical lens, whereby a user who views an image displayed on the display panel at a very close position does not perceive the light-blocking area, which improves the image quality of the display.

  • Patent number: 9830858
    Abstract: Disclosed herein are a display panel capable of improving high-resolution expression ability and a display device having the same. The display panel includes a plurality of unit pixels, each of which includes first and second sub-pixels alternately arranged in the same vertical line and a third sub-pixel arranged in a different vertical line than the first and second sub-pixels, wherein, when a bright (or dark) image is realized on a dark (or bright) background image, the color of the third sub-pixel is realized at leftmost and rightmost portions of the bright (or dark) image.
