  • Patent number: 10204930
    Abstract: A display device is described that has reduced resistance in one or more of the gate, common, data electrical lines that control the operation of the pixels of the display device. Reduced resistance is achieved by forming additional metal and/or metal-alloy layers on the gate, common, and/or data lines in such a manner so that the cross-sectional area of those lines is increased. As a consequence, each such line is formed so as to be thicker than could otherwise be achieving without causing defects in the rubbing process of an alignment layer. Additionally, no widening of these lines is needed, thus preserving the aspect ratio of the device. The gate insulating and semiconducting layers that in part make up the thin film transistors that help control the operation of the pixels of the device may also be designed to take into account the increased thickness of the lines.

  • Patent number: 10175541
    Abstract: It is possible to separate each liquid crystal display panel from a mother board in which multiple liquid crystal display panels are formed even with a thin glass substrate, by forming a columnar spacer in the boundary between liquid crystal display panels, forming a scribe line corresponding to the columnar spacer on both sides of the counter substrate and the TFT substrate in the mother board, and forming a separation line between the scribe lines by applying a bending stress to the mother board. Since the columnar spacer is formed in a portion corresponding to the scribe line, the strength in this portion increases, so that the proper scribe lines and break lines can be formed when the thickness of the glass substrate is reduced to about 0.15 mm.

  • Patent number: 10114242
    Abstract: An automatic-darkening filter 10, 10? that comprises a first polarizer 14, a second polarizer 18, a first liquid-crystal cell 16, and a sensor 64. The first polarizer 14 has a first polarization direction, and the second polarizer 18 has a second polarization direction. The liquid crystal cell 16 is disposed between the first and second polarizers 14, 18 and contains first and second optically-transparent, flexible, glass layers 40 and 42 with the liquid crystal layer 48 being located between these layers. The sensor 64 detects incident light and causes a signal to be sent, which causes molecular rotation within the liquid crystal layer. The inventive automatic-darkening filter is beneficial in that overall product weight can be reduced and the view field can be increased.
