A display panel, its driving method and display device

Abstract

The invention discloses a display panel, its driving method and a display device. In the invention, a compensation circuit is added to the display area, and the compensation circuit includes at least one shift unit, at least one shift unit is electrically connected to a grid line, and the shift The bit units are electrically connected between two ends of the corresponding gate lines, so that at least one gate line is simultaneously driven by two electrically connected shift registers and one shift unit. In this way, for a large-size display panel, not only two shift registers located on both sides of the display area are used to input a gate signal to a gate line, but also a shift unit located in the display area is used to directly send signals between the two ends of the gate line. Inputting the compensation signal can reduce the rise time and fall time of the grid signal in the display area such as the middle area, thereby increasing the charging rate and reducing the uneven display of the display panel caused by the RC Delay of the grid signal, so that the present invention can achieve uniform display. Purpose.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a driving method thereof and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) is currently the fastest-growing display technology, which has the advantages of self-illumination, fast response, high brightness, wide viewing angle, bright colors, and thinness. At present, in order to realize the narrow border, the gate scanning signal output of OLED mainly adopts GOA (Gate Driver on Array, display panel line drive) technology to integrate TFT (Thin Film Transistor, thin film transistor) gate switch circuit on the display panel of the display panel. To form a scan drive for the display panel. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a display panel, its driving method and a display device, which are used to solve the problem of a large-sized display panel havin...
