Abstract

The invention discloses a shifting register unit and a shifting register, and the shifting register unit comprises a shifting register module and a high-voltage discharge module; wherein the shifting register module is connected with a signal input end, a first reset signal end, a first low level end, a high level end, a first clock signal end and a second clock signal end; and the high-voltage discharge module is connected with an output end, a high level end, a signal input end, a first reset signal end, a second reset signal end, a first low level end and a second low level end of the shifting register module. According to the invention, the shifting register unit comprises the high-voltage discharge module which is connected with the shifting register module in series, the voltage difference of power supply for grid line is increased, the discharge speed is improved, the time of output voltage signal decrease is reduced, and the high-resolution requirement of an existing display device is met.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register unit and a shift register. Background technique [0002] In recent years, flat panel displays, such as Thin Film Transistor-Liquid Crystal Display (TFT-LCD) and Active Matrix Organic Light Emitting Diode (AMOLED), have been It is widely used in electronic products such as TVs and mobile phones because of its advantages of thinness and low power consumption. [0003] A TFT-LCD or AMOLED display panel is composed of a matrix of pixels in both horizontal and vertical directions, and each pixel in the display panel is driven to display by a driving circuit. The drive circuit mainly includes a gate drive circuit and a data drive circuit, wherein the data drive circuit is used to sequentially latch the input data according to the clock signal and convert the latched data into an analog signal and input it to the data line of the display panel. The gate drive circuit...
