  • Publication number: 20250081786
    Abstract: The present application provides a display panel and an electronic device. The display panel includes first pixel unit groups and second pixel unit groups. Each first pixel unit group and each second pixel unit group both include two pixels which are center-symmetrical to each other. Each pixel includes at least three light-emitting units of different colors arranged at intervals. In any two adjacent pixels, one of the light-emitting units of one pixel has the same color as the adjacent light-emitting unit of the other pixel, so as to alleviate a problem of color mixing between pixels in conventional organic light emitting diode (OLED) devices.

  • Patent number: 11296168
    Abstract: The present invention provides a display panel. The display panel includes at least three sub-pixel regions. The sub-pixel regions are arranged along a direction of a scan line. A channel region of each driving TFT in the same sub-pixel region has a same width-to-length ratio. Along a direction from a signal input end to a signal output end of the scan line, the width-to-length ratio of the channel region of each driving TFT of any of the sub-pixel regions is smaller than that of a previous one of the sub-pixel regions.

  • Publication number: 20220052130
    Abstract: The present disclosure provides a display panel and manufacturing method thereof, the display panel includes a TFT substrate, a flat layer, a pixel definition layer, an OLED device layer, and a light-shielding layer. The light-shielding layer disposed on a side of the pixel definition layer away from the TFT substrate, which can effectively block the light path, preventing light emitted by the OLED device layer from entering adjacent pixels after being transmitted and reflected by the transparent pixel definition layer, thereby preventing the problem of color mixing caused by light leakage between adjacent pixels.
