  • Patent number: 10969639
    Abstract: Provided is an array substrate including gate lines, data lines, and a first alignment layer above a layer where the gate lines are located and a layer where the data lines are located, the gate lines and the data lines being arranged to intersect with each other to divide the array substrate into pixel regions. Each pixel region includes first and second sides opposite to each other and third and fourth sides opposite to each other, each of the first and second sides connecting the third side to the fourth side and extending in one direction, lengths of the first and second sides being greater than lengths of the third and fourth sides, the first alignment layer having a first alignment direction, and each of the first and second sides forming an acute angle with the first alignment direction. A display panel and a display device are also provided.
    Type: Grant

  • Patent number: 9875419
    Abstract: Embodiments of the present invention provide a recognition device and an alignment system. The recognition device is configured to recognize an alignment mark on a display substrate and comprises a camera unit and a light source unit. The camera unit is configured to shoot the alignment mark, and the light source unit is configured to radiate emitted light onto the alignment mark. The recognition device further comprises a light processing unit configured to process light emitted from the light source unit so that the luminance of the light irradiated onto the alignment mark is greater than that of the light emitted from the light source unit. Through the arrangement of the light processing unit, the recognition device enables the luminance of the light irradiated onto the alignment mark to be greater than that of the light emitted from the light source unit.
