The manufacturing method comprises the following steps: A: Treating a surface of an electrode of an LCD panel, the surface at least comprising a contact surface with an Au ball, to diminish the adhesion of an alignment liquid to the contact surface and prevent the alignment liquid from not coating the contact surface; and B: Coating or printing the alignment liquid. Because the electrode surface to which an Au ball particle will be applied (namely the transfer pad) is treated before the application to diminish the adhesion of the alignment liquid to this surface, and no alignment layer will be formed on the surface of the transfer pad. Therefore, the alignment layer can be very wide, the uniformity of the alignment layer at the edge is good, the accuracy is high, the display effect on the edge of the LCD panel is improved, and the frame of the LCD panel is narrowed.

  • Patent number: 8669929
    Abstract: Disclosed is a gate printed circuit board, a connector-free liquid crystal display (LCD) panel assembly, a driving-signal timing module included in the liquid crystal display (LCD) panel assembly, and a method of driving the liquid crystal display (LCD) panel assembly. According to the present invention, since a separate connector and a gate printed circuit board of a conventional LCD panel is not required for applying a gate-driving signal generated from an external information processing device, a thickness and the number of parts of the LCD device is reduced. Further, when the gate-driving signal is transmitted through the TFT substrate, the voltage Voff for maintaining a thin-film transistor (TFT) in a turned-off state is modified so that users may not recognize the imbalance in brightness.

  • Patent number: 8665411
    Abstract: Techniques are provided for unifying steps of sealing material so that the yield and the reliability of a liquid-crystal display device become high. A starting film of scanning lines is patterned so that prismatic dummy wirings 301 for the first layer which are not electrically connected are formed in regions R1 and R2, and wirings 302 extending from the pixel section are formed in a region R3, and wirings 303 having connection end portions 303a are formed in a region R4. After an interlayer insulation film is formed, the starting film of the signal lines is patterned so that the dummy wirings 304 for the second layer are formed to embed the gaps between the wirings 301 to 303, and also the wirings 305 and the wirings 303 which extend from the pixel portion are connected to each other. This permits unification of the cross-sectional structure of the sealing material formation region.
