  • Patent number: 11694616
    Abstract: Provided is an organic light-emitting display panel. Pixel-driving circuits of subpixels in a same row of pixel units are connected to a same light emission control signal line. The pixel-driving circuits of the subpixels in the same row of pixel units are connected to a same reset control signal line; and an anode of a light-emitting element of each of the subpixels to which the pixel-driving circuits electrically connected to the reset control signal line belong is at a reset voltage. In a display period of each frame of image, in at least part of a period during which an i-th row of pixel units are in a light emission stage, anodes of light-emitting elements of a j-th row of pixel units are at a reset voltage; and the j-th row of pixel units and the i-th row of pixel units are adjacent two rows of pixel units.

  • Patent number: 11682352
    Abstract: Provided is an organic light-emitting display panel. Pixel-driving circuits for subpixels with a same color in a same row are connected to a same light emission control signal line, and the pixel-driving circuits of subpixels with the same color in the same row are connected to the same reset control signal line. Pixel-driving circuits of subpixels with different colors in the same row of pixel units are connected to different light emission control signal lines, and the pixel-driving circuits of subpixels with different colors in the same row of pixel units are connected to different reset control signal lines. In a display period of each frame, in part of a period when subpixels with an i-th color in the same row of pixel units are in a light emission stage, anodes of light-emitting element of subpixels with another color in the same row of pixel units are at a reset voltage.

  • Patent number: 10101833
    Abstract: The present disclosure provides a display panel and a manufacturing method therefor, and a display device, and the display panel includes a first substrate and a second substrate disposed opposite to the first substrate; an organic light emitting layer disposed between the first substrate and the second substrate, wherein the organic light emitting layer includes a planar cathode layer; a planar cathode protection layer disposed on the cathode layer; and a first touch layer disposed on the cathode protection layer. With the technical solutions according to the present disclosure, the first touch layer is formed by evaporation processes just like the organic light emitting layer, so that the manufacture steps of the display panel are reduced as compared to forming the first touch layer by a photo etching process. Further, if the evaporation mask instead of the photo etching masks is used during the manufacture, the production cost is reduced.
