  • Patent number: 10203820
    Abstract: Embodiments of the invention provide a self-capacitance touch liquid crystal grating, a manufacturing method thereof, a driving method thereof, a self-capacitance touch liquid crystal 3D display panel, and a self-capacitance touch liquid crystal 3D display device. In the grating provided by embodiments of the present invention, as orthographic projections of strip-shaped electrodes on a sensing electrode layer are respectively located in row spacing areas or column spacing areas formed through sensing electrodes arranged in a matrix form, the sensing electrode-to-earth capacitance is located between a surface-shaped electrode and the sensing electrodes, and the strip-shaped electrode will not cause the sensing electrode-to-earth capacitance to be increased. Therefore, RC loading of the sensing electrodes can be largely reduced, and also the interference between the sensing electrodes and the grating can be avoided, so that touch operations will not interfere with operations of the grating.

  • 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.
