    Abstract: The present invention provides a display panel and a display device thereof. The display panel includes a substrate, a reflective layer, pixel retaining walls, first electrodes, a light emitting layer, and a second electrode. In the present invention, by adjusting refractive indexes of first electrodes in each sub-pixel region with different colors, microcavity effects are used to enhance color saturation of emitted light and component efficiency. In this way, difficulties resulting from using vacuum evaporation methods along with fine masks to prepare hole transport layers with different thickness and problems such as low utilization of evaporation material are prevented.

  • Patent number: 11251259
    Abstract: An organic light-emitting diode display may have rounded corners. A negative power supply path may be used to distribute a negative voltage to a cathode layer, while a positive power supply path may be used to distribute a positive power supply voltage to each pixel in the display. The positive power supply path may have a cutout that is occupied by the negative power supply path to decrease resistance of the negative power supply path in a rounded corner of the display. To mitigate reflections caused by the positive power supply path being formed over tightly spaced data lines, the positive power supply path may be omitted in a rounded corner of the display, a shielding layer may be formed over the positive power supply path in the rounded corner, or non-linear gate lines may be formed over the positive power supply path.
