  • Publication number: 20240088213
    Abstract: A semiconductor device includes a drift region, a dielectric film, and an anti-type doping layer. The drift region has a first type conductivity. The anti-type doping layer is located between the drift region and the dielectric film, and has a second type conductivity opposite to the first type conductivity so as to change a current path of a current in the drift region, to thereby prevent the current from being influenced by the dielectric film. A method for manufacturing a semiconductor device and a method for reducing an influence of a dielectric film are also disclosed.

  • Patent number: 11079877
    Abstract: A display driving circuit, suitable for a display device, includes multiple data circuits and multiple reading circuits. Each data circuit is configured to provide multiple data signals to corresponding ones of data lines of the display device. Each reading circuit is configured to compare multiple sensing signals on corresponding ones of sensing lines of the display device to generate a sensing result, and is configured generate multiple coupling signals according to the multiple data signals of a corresponding one of the multiple data circuits, respectively. The reading circuit is further configured to provide the multiple coupling signals to the corresponding ones of the multiple sensing lines. When the multiple data signals have one or more rising edges, the multiple coupling signals have one or more positive pulses. When the multiple data signals have one or more falling edges, the multiple coupling signals have one or more negative pulses.
