Description

technical field

[0001] The present invention relates to the technical field of display panel control, and 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, shield 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. However, after the gate line is shielded, the load capacitance of the gate line is greatly increased, and the driving delay of the gate line is also greatly increased. The time required for the charging and discharging of the polar signal is prolonged, so that when applied to ultra-high resolution, it cannot meet the needs of pixel charging, and the leakage area increases, which cannot guarantee the requirements of the high aperture ratio frame of th...
