Description

technical field [0001] The present invention relates to the technical field of display panel control, in particular to a control circuit, a driving method and a display device for a display panel. Background technique [0002] In order to increase the pixel aperture ratio and reduce light leakage around the gate lines, shielding electrodes are used to shield part of the gate lines. In the prior art, when the gate line is turned on, the shielding electrode disposed above the gate line is still connected to the common electrode, and since the gate line load capacitance increases greatly after the gate line is blocked, the gate line driving delay also increases greatly, resulting in The time required for charging and discharging the pole signal is prolonged, so that when it is applied to ultra-high resolution, it cannot meet the demand for pixel charging, and the leakage area increases, which cannot guarantee the high aperture ratio frame of the pixel.

Problems solved by technology

[0003] The main purpose of the present invention is to provide a control circuit, a driving method and a display device for a display panel, which solve the problem that in the prior art, when the gate line is opened, the shielding electrode arranged above the gate line is still connected to the common electrode, and Since the load capacitance of the gate line increases significantly after the gate line is blocked, the delay of the gate line drive also increases greatly, resulting in a longer time for charging and discharging the gate signal, making it impossible to meet the pixel charging requirements when applied to ultra-high resolution, and leakage The area increases, and the problem that the pixel high aperture ratio frame cannot be guaranteed
