  • Patent number: 10884293
    Abstract: A display and a method of coating an alignment film are provided. The method of coating an alignment film includes step S10, providing substrate to-be-coating with the alignment film, positioned the substrate to-be-coating with the alignment film on optical bench; step S11, pressing against to the substrate by a print wheel has alignment film printing template, and rolling by predetermined coating direction, uniform coating alignment liquid on to-be-coating region of the substrate; wherein, the substrate rolling with the optical bench and forms changing angle with horizontal surface during the coating process; and step S12, controlling the optical bench for driving the substrate to vibrate after coating the to-be-coating region. In this invention provides a method could suit to difference mobility alignment film, it could greatly enhances uniformity of the alignment film such decrease opportunity to Mura happened by worse quality of printing the alignment film.

  • Publication number: 20200312204
    Abstract: The present invention provides a clamper and a lighting fixture. An elastic layer for contacting a panel is disposed on a rotatable clamping portion. In addition to that, a distance from a lowest point of one end of the panel clamped by the rotatable clamping portion to a carrier plate supporting a polarizer at one side of the panel adjacent to a thin film transistor is greater than a thickness of the polarizer. Accordingly, the present invention prevents the panel and the polarizer at one side of the panel adjacent to the thin film transistor from being damaged from clamping.
