Problems solved by technology

[0006] The embodiment of the present invention provides a shift register and a display device to solve the problem that in the existing shift register, the potential of the pull-down node is controlled by the potential of the pull-up node. Fluctuations in the potential may cause the potential of the pull-down node to be abnormal, resulting in an abnormal problem in the signal output by the shift register

Embodiment Construction

[0023] A shift register and a display device provided by an embodiment of the present invention use different modules in the shift register to independently control the potential of the pull-up node and the potential of the pull-down node, so that the potential of the pull-down node is not affected by the pull-up node. The influence of the potential of the pull-up node avoids that when the potential of the pull-up node fluctuates, the potential of the pull-down node is abnormal, resulting in an abnormal problem in the signal output by the shift register.

[0024] The specific implementation manners of a shift register and a display device provided by the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0025] A kind of shift register provided by the embodiment of the present invention, such as figure 2 As shown, it includes a first pull-up module 21, a second pull-up module 22, a transmission module 23, a pull-down mo...

Abstract

The embodiment of the present invention provides a shift register and a display device to solve the problem that in the existing shift register, since the potential of the pull-down node is controlled by the potential of the pull-up node, once the potential of the pull-up node Fluctuations may cause the potential of the pull-down node to be abnormal, resulting in an abnormal problem in the signal output by the shift register. The shift register uses the first pull-up module and the pull-down module to control the potential of the pull-up node, and uses the second pull-up module and the pull-down node control module to control the potential of the pull-down node, thereby preventing the potential of the pull-down node from being affected by the pull-up The potential of the node is controlled, thereby preventing the potential of the pull-down node from being affected by the potential of the pull-up node.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register and a display device. Background technique [0002] The liquid crystal display panel is composed of a two-dimensional liquid crystal pixel matrix. The driving device of the liquid crystal display panel includes a gate driving device and a data driving device. The data driving device latches and converts the input display data into analog signals in sequence, and scans the liquid crystal display in sequence. The data line of the panel; the gate drive device includes several shift registers, and the signal at the control signal output end of each stage shift register will be transmitted to the reset signal input end of the upper stage shift register and the next stage shift register. The control signal input terminal of the bit register. Each stage of the shift register converts the input clock signal into an on or off signal and outputs it from its control signa...
