  • Patent number: 10152178
    Abstract: Disclosed is an active matrix liquid crystal display device with transverse electric field system, which improves afterimage. One electrode of many pixel comb electrodes is thicker in width than the other pixel comb electrode and common comb electrodes and is equal to a width of the common shield electrode covering through a second insulator film on video signal wirings. The display area is divided into two sub areas by the thick pixel comb electrode. The pixel comb electrode and the common comb electrode have the same number in each sub area. As the common shield electrode and the thick pixel comb electrode have the same width, the concentration of electric field can be eased near the pixel comb electrodes. The electric potential distribution becomes symmetric by symmetric configuration, reducing asymmetric lighting mode between frames. DC offset of the video signal after flicker adjustment decreases and the afterimage improves.

  • Patent number: 9995954
    Abstract: A conductive film stuck to a transparent conductive film of a liquid crystal panel is protruded along a display surface and the protruded part is formed as non-adhesive so that the protruded part is not stuck to the members other than the liquid crystal panel. The protruded part contacts with a conductor on the front frame side so as to electrically connect the transparent conductive film of the liquid crystal panel and the front frame. When the liquid crystal panel moves, the conductive film can move in a direction in parallel to the display surface by following the liquid crystal panel, which prevents deterioration of the conductive film. Therefore, no excessive force works on the stuck part between the transparent conductive film and the conductive film. It solves the exfoliation issue of the conductive film, and the transparent conductive film can be electrically connected to the front frame stably.
