  • Patent number: 9658494
    Abstract: The present invention provides a display substrate, a mother substrate for display substrates and a display device. The display substrate comprises a display area and a non-display area surrounding the display area, wherein an alignment layer is disposed in the display area and the non-display area. In the display substrate according to the present invention, by providing the same pattern of alignment layer in both of the non-display area and the display area of the display substrate, the Mura defect caused by the difference of surface roughness between the display area and the non-display area of the display substrate may be significantly reduced, and a large amount of small foreign matters gathered due to the rubbing between the rubbing cloth and metal residuals may also be significantly reduced. Therefore, the yield of production and the quality of products may be improved.

  • Patent number: 9651825
    Abstract: A liquid crystal lens display device, which includes a backlight module and a liquid crystal structure. The liquid crystal structure includes a liquid crystal layer, a quantum dot layer, and a light shield structure. The liquid crystal layer defines multiple display pixels, and each display pixel may be switchable between an on state and an off state. The light shield structure includes two shield layers, each having multiple openings and multiple shield portions alternatively positioned. When the display pixel is in the on state, the liquid crystal molecules form at least one liquid crystal lens to refract the light beams, and the refracted light beams penetrate through the openings of the light shield structure to reach the quantum dot layer. When the display pixel is in the off state, the light beams will not be refracted, and will thus be blocked by the light shield structure.

  • Patent number: 9541802
    Abstract: The present invention discloses a TFT array substrate and a display panel. Multiple pixel electrodes structured with at least one domain are arranged in each pixel area, and the angle/angles of at least one deflection in the same-sided deflections of the pixel electrodes of the same domain in the pixel area in the direction parallel to the initial arrangement direction of liquid crystal not driven by a voltage to rotate is different from the angles of other deflections. Through the design of different deflection angles of the pixel electrodes of the same domain, even under a low gray scale, since the rotating angles of liquid crystal molecules driven by different pixel electrodes are different, the inner parts of the liquid crystal molecules driven by the pixel electrodes may be relatively completely compensated.
