The present invention provides a curved display device, and relates to the field of display technology. The curved display device comprises a plane display panel and a gradient index lens provided at light exit side of the plane display panel, wherein the gradient index lens makes light exiting from the plane display panel converge toward a center of display surface of the curved display device. In the present invention, by adding a gradient index lens to a traditional plane display panel and using refraction effect of light by the gradient index lens, curved display is achieved without curving the display panel, thus poor display caused by curving the display panel is effectively avoided.

Curved display device

The application relates to a shift register unit and a driving method thereof, a shift register circuit and a display apparatus. The shift register unit may include a gate starting terminal, a first clock terminal, a second clock terminal, a reset terminal, a low level terminal, a gate output terminal, a storage capacitor, a charging module, an output control module and a reset module. In the shift register according to the present application, since the reset operation is under control of the second transistor and the fifth transistor both, an improper reset operation will not occur, even if the signal at the reset terminal is unstable.

Shift register unit and driving method thereof, shift register circuit, and display apparatus

The present disclosure provides a gate driving circuit, a gate driving method and a liquid crystal display. Said gate driving circuit includes shift registers at a plurality of stages, wherein the shift register at each stage includes a pull-up driving unit, a pull-up unit, a reset unit, a pull-down unit and a supplementary unit; said pull-up unit is used for making a clock signal at a first clock terminal an output signal of the shift register at the present stage when being turned on; said supplementary unit, connected to said pull-up unit, is used for making a clock signal at a second clock terminal the output signal of the shift register at the present stage when being turned on. With the supplementary unit, the present disclosure can reduce voltage jump of a pixel, achieve the MLG function and enhance the picture quality of the LCD.

Gate driving circuit and method, and liquid crystal display

The present invention discloses a shifting register and an apparatus for driving gate lines, and it relates to Liquid Crystal Display technical field, for reducing the noise of a shifting register during non-working period.
