  • Publication number: 20220165836
    Abstract: A transparent display device may have high transmittance and at the same time have high resolution. The transparent display device comprises a first signal line portion extended in a first direction, including a first sensing scan line, a second sensing scan line, an initialization line and a light emission control line, a second signal line portion extended in a second direction, a transmissive area provided between two adjacent first signal line portions and between two adjacent second signal line portions, and a pixel provided in an intersection area where the first signal line portion and the second signal line portion cross or overlap each other. The light emission control line overlaps the initialization line in at least a partial area.

  • Patent number: 10360854
    Abstract: A display device according to an embodiment of the present disclosure comprises a display panel including a display area having a plurality of pixels connected to a plurality of gate lines, a gate driving circuit in a non-display area adjacent to the display area and including a plurality of stages supplying a gate signal to the plurality of gate lines, and an auxiliary load connected to at least one stage of the plurality of stages in the non-display area in which a number of the plurality of pixels which are connected to at least two gate lines among the plurality of gate lines varies. Therefore, the load applied to the output node of the gate driving circuit is uniformly adjusted so that a screen abnormality of the display device may be suppressed.

  • Patent number: 10025110
    Abstract: An autostereoscopic display and a method for driving the same are discussed. The autostereoscopic display according to an embodiment includes a display panel displaying data of a left eye image and data of a right eye image and a three-dimensional (3D) cell which is positioned on the display panel or is embedded in the display panel and separates optical axes of the left eye image and the right eye image. A frame rate of the 3D cell is greater than a frame rate of the display panel.

  • Patent number: 9355455
    Abstract: An image data processing method comprises: extracting a depth map from an input image; separating the input image into a foreground area and a background area based on grayscales of the depth map; and modulating the maximum depth value of the input image to become smaller and the difference between depth values of a gray grayscale segment of the depth map to be greater than the difference between depth values of the foreground area and background area of the input image.
