  • Patent number: 11977302
    Abstract: A cholesteric liquid crystal display device and a driving method for improving non-uniform image quality of the cholesteric liquid crystal display device. The cholesteric liquid crystal display device includes a cholesteric liquid crystal display panel and a liquid crystal drive unit. The cholesteric liquid crystal display panel is composed of multiple row circuit structures and multiple column circuit structures. The liquid crystal driving unit sequentially outputs column driving voltages to a plurality of column circuit structures in a scanning manner. After scanning the multiple column circuit structures, the liquid crystal driving unit applies an unselected voltage to the multiple column circuit structures together with more than 18 times the scanning unit time course, so as to make the brightness of the overall picture more uniform.

  • Patent number: 11947204
    Abstract: A cholesterol liquid crystal display device includes a liquid crystal display panel and a liquid crystal driving unit. The liquid crystal display panel has a plurality of pixels. The liquid crystal driving unit applies row driving voltages and column driving voltages to a designated pixel according to the input signal. After the input signal is transmitted, the liquid crystal driving unit activates the power-down signal within a certain period of time to reduce the row driving voltage and the column driving voltage applied to the specified pixel. Thereby, the crosstalk phenomenon on the cholesteric liquid crystal display device can be improved.

    Abstract: A level shifter includes a cross-coupled transistor pair, first through third cascode transistor pairs and a differential input pair sequentially coupled in series, and further includes a sub level shifter. The first cascode transistor pair is controlled by a first reference voltage. The second cascode transistor pair is controlled by a pair of differential control voltages. The third cascode transistor pair is controlled by a second reference voltage lower than the first reference voltage. The differential input pair is controlled by a pair of differential input voltages. The sub level shifter generates the differential control voltages according to the differential input voltages and the first and second reference voltages. The differential control voltages are switched between the first and second reference voltages. The level shifter outputs a pair of differential output voltages through inverted and non-inverted output terminals coupled with the second cascode transistor pair.
