  • Publication number: 20230360601
    Abstract: Disclosed are driving circuit of a display unit, a driving method of the display unit, and a display device. Driving circuit of the display unit compensates light-emitting circuit 5 at the first connection point A, so that when the light-emitting circuit 5 drives the display unit 6 to emit light, which compensates the light-emitting circuit 5 through the coupling balance circuit 7 to reduce the signal interference caused by the compensation circuit 3 to the first connection point A, and then reduces the voltage fluctuation of the first connection point A. The compensation of the first connection point A to the light emitting circuit 5 is more stable, so that when the light emitting circuit 5 drives the light emitting unit 6, the light emitting unit 6 is more stable, thus improving the display effect of the display unit 6.

  • Patent number: 11521566
    Abstract: The present disclosure provides a display panel and an electronic device. In the display panel, a contact area between a support pillar and a bottom layer is increased, without changing a size of a single sub-pixel, thereby alleviating a technical problem that the support pillar easily peels off in an existing 8K ultra-high-resolution electronic device. Moreover, by adjusting voltage drop values of clock input transistors in different GOA units, the voltage drop value between each of the GOA units and clock driving chips is approximately the same.

  • Patent number: 11513401
    Abstract: A liquid crystal display module and a display device are provided. An end surface of a binding terminal is combined with an end surface of an array substrate to form a contact surface. The contact surface is disposed obliquely to any side surface of the array substrate. A conductive film is fit to and electrically connected with the contact surface. By increasing area of the contact surface between the binding terminal and the first conductive film, a contact resistance can be effectively reduced. The flip-chip film is bent at least twice to reduce a damage to the flip-chip film during bending.

  • Patent number: 11366349
    Abstract: A liquid crystal display panel and a manufacturing method of a display module are provided. Cutting guide slots are formed on a transparent base of the liquid crystal display panel, and depths of the cutting guide slots are less than a thickness of the transparent base, which does not affect normal attachment of polarizers, so that after the polarizers are attached on the liquid crystal display panel, due to a presence of the cutting guide slots, strong laser energy is not required to realize cutting of the liquid crystal display panel, which improves cutting yield.

  • Publication number: 20210356802
    Abstract: A display panel, and a method of manufacturing the same are provided. The display panel includes a display region and a non-display region. The display region is disposed at a center of the display panel. The non-display region is disposed around the display region. One side of the non-display region is provided with an identification code pattern. The identification code pattern is provided by using an exposure machine and then printed by a coding machine. The identification code pattern is a regular graphic.
