  • Publication number: 20240194136
    Abstract: A display panel and a display device is provided in the present disclosure, which belongs to the field of display technologies. The display panel includes a base substrate and a plurality of pixel circuits disposed on the base substrate. At least two pixel circuits in a same column are coupled with a same first initial power line, such that only a small quantity of signal lines need to be disposed on the base substrate. Accordingly, an area which needs to be occupied by the signal lines and is of the base substrate becomes smaller, thereby facilitating high-resolution design of the display panel.

  • Patent number: 11954291
    Abstract: A touch panel and a manufacturing method thereof, and a display device. An insulation layer (4) positioned between a substrate (1) and a polarizer (3) is configured to comprise a silicon nitride layer (41) and a barrier layer (42) positioned at one side of the silicon nitride layer (41) away from the substrate (1). The barrier layer (42) can serve as a covering layer that stops an ammonia gas escaped from the silicon nitride layer (41) from moving to the polarizer (3) so as to prevent fading of the polarizer. The insulation layer (4) is configured to comprise two thin layers, namely a silicon nitride layer (41) and a barrier layer (42).
