The present disclosure provides a GOA circuit and a display panel, wherein the GOA circuit is provided with a second pull-down control circuit unit (). Combined with a timing diagram, during a touch period, for a gradual transmission first node (Q), through a third control signal (GAS) and a second control signal (DU), the first node (Q) changes from a low-level signal to a high-level signal, so that two leakage paths of the first node (Q) disappear, and there is no leakage path at the first node Q during touch, thereby maintaining stability of the first node Q.

GOA circuit with second pull-down control circuit unit and display panel

The embodiments of the disclosure disclose an image processing method and an device thereof, by detecting the saturated color ratio of the current frame picture of the acquired target image to acquire a corresponding PWM duty ratio and gain coefficient, the method can intelligently control the backlight brightness of the display picture and the gain coefficient during the format conversion to solve the problem that the unsaturated color is darker than the saturated color when the picture is displayed, and the display effect of the terminal is improved.
