  • Publication number: 20190170918
    Abstract: An irregular shaped display panel, a method and a device for manufacturing the irregular shaped display panel, and a display device are provided. The irregular shaped display panel includes a display area and a non-display area surrounding the display area. The method for manufacturing an irregular shaped display panel includes: determining, based on an irregular shaped region on the display panel, boundary pixel units located on a boundary of the irregular shaped region; dividing each boundary pixel unit into at least two pixel division units such that each pixel division unit comprises parts of all sub-pixels of the boundary pixel unit; and determining whether a ratio of an area of each pixel division unit outside the display area to an area of the entire pixel division unit reaches a preset value; if yes, performing a shading process on the pixel division unit.

  • Publication number: 20190073932
    Abstract: A shift register unit includes an input circuit, an output circuit, a pull-down control circuit, and a pull-down circuit. The pull-down control circuit is coupled to a first power supply signal terminal, a second power supply signal terminal, a pull-up node, a pull-down node, and a reset signal terminal. The pull-down control circuit is configured to transmit a first power supply signal from the first power supply signal terminal to the pull-down node under a control of the first power supply signal, transmit the first power supply signal from the first power supply signal terminal to the pull-down node under a control of the reset signal, and transmit a second power supply signal from the second power supply signal terminal to the pull-down node under a control of the pull-up node.
