  • Patent number: 12001035
    Abstract: A display substrate and a display device are provided. The display substrate includes a plurality of repeat units. Each of the plurality of repeat units includes one first-color sub-pixel, one second-color sub-pixel pair and one third-color sub-pixel which are arranged in a first direction, the second-color sub-pixel pair includes two second-color sub-pixels arranging in a second direction. In three sub-pixels of different colors which are adjacent to each other, orthographic projections of light-emitting layers of at least two sub-pixels adjacent to each other on the base substrate are overlapped or connected, and a spacing is disposed between at least part of the light-emitting layers of two sub-pixels which are adjacent to each other.

  • Patent number: 11990363
    Abstract: A wafer support pin lifting device includes a support plate, a slide block and a lifting pole. The support plate is for supporting multiple support pins. The slide block is slidably connected to an inner wall of a cavity so that the slide block slides relative to the cavity. The lifting pole has a first end, a second end and a third end. The first end is connected to the support plate, the second end is pivotally connected to the slide block, and the third end is connected to an actuator. With the pivotal connection between the second end of the lifting pole and the slide block, the lifting pole approaching the high position causes the support plate to be approximately horizontal, and the lifting pole approaching the low position causes the support plate to be tilted.
