Grid control unit, grid control circuit, array substrate and display panel

Abstract

The invention discloses grid control units, a grid control circuit, an array substrate and a display panel. Each grid control unit comprises a grid drive subunit for driving a line of grid line, a first zero clearing subunit for carrying out zero clearing on the grid drive subunit after the grid drive subunit drives one line of grid line, and a pause and restarting subunit for controlling the grid drive subunit to enable the grid drive subunit to pause and restart. Through arranging the pause and restarting subunit in the grid control unit, the grid control unit can be controlled to pause and restart; furthermore, through the grid control circuit formed by cascading the grid control units grade by grade, a plurality of pauses and restarting can be realized in one frame; and the display panel applied with the grid control circuit can carry out touch signal scanning in a pause time, so that stability of a display system and high report rate of a touch control system and better linearity and the like can be kept.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate control unit, a gate control circuit, an array substrate and a display panel. Background technique [0002] Recently, with the development of display technology, the application of display panels has become more and more extensive. When the display panel is working, the gate control circuit in the display panel needs to generate scanning signals to drive each gate line in the array substrate one by one, so that the data signal can be transmitted to each pixel unit in the array substrate. The above-mentioned scanning signal is generated by the gate control unit having a shift register function in the gate control circuit. [0003] figure 1 is a circuit diagram of a prior art gate control unit. Such as figure 1 As shown, the gate control unit includes: the gate of the first NMOS transistor MN1 is electrically connected to the trigger signal input terminal SET fo...
