Abstract

The invention discloses a scanning driving unit, a circuit and a display panel. The scanning drive unit includes: a scanning signal input terminal, a reset signal control terminal, a first potential signal input terminal, a second potential signal input terminal, a scanning signal output terminal, an output signal control terminal, a scanning control module, a reset module, an output module, A pull-up module, a pull-down module and a compensation module, wherein: the output module includes a first node and a second node; the potential of the second node is controlled by the scan control module and the pull-down module, and the potential of the first node is controlled by the pull-up module and the second node The potential control of the pull-down module includes a pull-down branch, the first end of the pull-down branch is connected to the second node, and the second end of the pull-down branch is connected to the second end of the compensation module. Through the present invention, the possibility of dark lines appearing on the display panel due to electric leakage in the scanning drive unit during the touch detection process can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a scan driving unit, a circuit and a display panel. Background technique [0002] In recent years, with the gradual development of touch technology, the display panels of smart phones, smart tablets, wearable devices and other devices generally use touch display panels with touch functions. When implementing a touch display panel, the touch module can be installed outside the display panel or integrated into the display panel. In order to make the touch display panel thinner, more and more technologies choose to integrate the touch module inside the display panel. [0003] Although integrating the touch module into the display panel can reduce the overall thickness of the touch display panel, it will also bring new problems, which will easily affect the normal display effect of the display panel. Therefore, how to reduce or eliminate the adverse effect of the ...
