  • Patent number: 8873005
    Abstract: A method for manufacturing an alignment layer is provided. An alignment material having an ultraviolet reactive functional group is formed on a substrate. A pre-baking process is performed on the alignment material located on the substrate. An ultraviolet polarizer is provided on the substrate. An aligning process is performed on the pre-baked alignment material, so as to irradiate an ultraviolet light to the substrate. The ultraviolet light passes through the ultraviolet polarizer and irradiates to the pre-baked alignment material. A post-baking process is performed on the alignment material after being aligned, so as to fully cure the alignment material.

  • Patent number: 8736776
    Abstract: The present invention provides a liquid crystal lens for a 3D display, which includes a first substrate, a second substrate, a liquid crystal layer, a first electrode layer, and a first alignment layer. The second substrate is disposed corresponding to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. The first electrode layer is disposed on a side of the first substrate facing the second substrate. The first alignment layer is disposed on the first electrode layer. The first alignment layer has a plurality of first regions, and alignment directions of the first regions gradually change from one end to an opposite end and are symmetrical. A manufacturing method thereof is also disclosed.

  • Publication number: 20130260030
    Abstract: Disclosed is a method for manufacturing a flexible display panel. The method includes the following steps: forming a patterned thermal adhesive layer including at least one hollow area on a substrate; coating a polyimide solution; baking the patterned thermal adhesive layer and the polyimide solution, so that an adhesion force between the patterned thermal adhesive layer and the substrate is enhanced and the polyimide solution is formed into a polyimide layer; manufacturing a plurality of display elements on the polyimide layer in the hollow area for forming the flexible display panel; and cutting the flexible display panel. The present invention is capable of achieving an objective of easily separating the flexible display panel and the substrate from each other.

  • Publication number: 20030137981
    Abstract: A switch controller controlled by a Link layer protocol is provided. The controller does not occupy any IP address, and is capable of parsing control frames based on the Link layer protocol. The controller comprises: a reception unit for receiving a packet; a parsing unit for parsing a control frame in the packet and for generating a control signal based on the control frame; a packet buffer for storing the packet; a protocol-processing unit for modifying the control frame based on the control signal; and a transmission unit for transmitting the packet after being processed by the protocol-processing unit.
