Abstract

The invention provides a display panel with a display area integrated with a gate drive circuit. The display panel is characterized in that a single data line, or a single gate drive signal line, or data lines and data lines arranged side by side, or gate drive signal lines and gate drive signal lines arranged side by side are arranged between any two same adjacent columns of sub-pixels, so that the gate drive signal lines and the data lines are not arranged side by side between any two same adjacent columns of sub-pixels, and the problem that, in order to further reduce the frame of the display panel, the gate drive circuit is led out from the display area, so that data lines and the gate drive signal lines may be arranged side by side between any two same adjacent columns of sub-pixels, the data lines are easily interfered by parasitic capacitance generated between the data lines and the gate drive signal lines, the data voltage maintained when the pixel corresponding to the new data line performs image display is unstable, and the problem that the display panel has abnormal pictures is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel with integrated gate drive circuits in the display area. Background technique [0002] Current gate drive circuits, such as GOA (Gate Driven on Array) circuits are mainly designed on one or both sides of the display panel. With the continuous development of full-screen mobile phones, and in the face of When the application shapes of display panels such as vehicles are more diverse and complex, the frame of the display panel is required to be narrower and narrower. When the width of the gate drive circuit cannot be compressed, the frame of the display panel cannot be reduced any more. Based on this defect, researchers have proposed GIA (Gate Driven in Array) technology, that is, the technology of integrating the gate drive circuit in the display area of ​​the display panel. It is directly drawn from the display area of ​​the display panel, so that the f...
