  • Patent number: 11983362
    Abstract: A first detection signal creation unit has detection nodes connected to detection electrodes in one-to-one correspondence. The first detection signal creation unit supplies charge from each detection node through a second wire to the relevant detection electrode so that a voltage at the relevant detection node vibrates according to an alternating-current voltage, and creates first detection signals matching the supplied charge. First filters are provided in first paths, each of which branches from an alternating-current output node to a first wire. A phase difference signal creation unit creates a phase difference signal matching the phase difference between the alternating-current voltage and one of the first detection signals.

  • Patent number: 11983375
    Abstract: Embodiments include a method and system for projected capacitive (PCAP) touchscreen construction with laser ablation. In glass/film/film (GFF) PCAP touchscreens, the films are coated with indium-tin-oxide (ITO), patterned by printing silver ink, and by ablating both the ITO and silver with a laser. A similar process occurs for a glass/glass (2GS) PCAP touchscreen. Embodiments include varying the pattern with which the laser ablates ITO on film within the touch area to improve touchscreen sensitivity. For example, by varying the width of patterns of floating ITO islands such that widths are less than or equal to a plan-view electrode gap between vertical and horizontal electrode pads and larger elsewhere, the touch sensitivity of the PCAP touchscreen may be improved and/or maximum touchscreen size may be increased.

  • Patent number: 11961485
    Abstract: The present invention relates to a cholesteric liquid crystal display, a liquid crystal driving unit, and a driving method for reducing the maximum driving voltage. The cholesteric liquid crystal display comprises a cholesteric liquid crystal display panel, a temperature detecting device, and a liquid crystal driving unit. If the temperature detecting device detects a temperature below the optimal range for the cholesteric liquid crystal display panel, the liquid crystal driving unit will operate the cholesteric liquid crystal display panel in DDS timing mode. When the temperature detecting device detects that the temperature of the display panel exceeds the optimal temperature range, the liquid crystal driving unit will operate the display panel in PWM timing mode, which can solve the problem of increased power consumption caused by changes in ambient temperature, and can greatly improve the better color level.
