Abstract

The invention discloses a display panel, a drive method thereof, and a display device. The display device comprises the display panel, and the display panel comprises a pixel unit formed by the crossing of a plurality of rows of scanning lines and a plurality of columns of data lines, wherein each row of scanning lines are connected with one GOA array substrate scanning line drive unit for providing a scanning line drive signal. A switching unit is disposed between each drive unit and a corresponding scanning line, and the corresponding drive unit and scanning line are turned on and off by theswitching unit in an even-odd manner. Through the control of the on / off of an odd switch or an even switch, the display device can detect the defective area of the pixel unit, avoids the occurrence of the missed detection, and can accurately locate the defective specific position.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display panel, a driving method thereof, and a display device. Background technique [0002] At present, the development trend of the liquid crystal panel industry is to design low-cost, narrow-frame products, and the scheme of designing scan line drive circuits on the array substrate to replace the scan line driver function is usually adopted. Such as figure 1 As shown, the current array substrate includes a pixel area formed by intersecting row scanning lines and column data lines, and each row scanning line is driven by a corresponding array substrate scanning line driver unit (Gate Driver On Array, GOA unit). When doing AT (Array Test, array test) in the driving process of the area, when all the driving signals of the driving unit are set to high level, the effective display test of the pixel area of ​​the array substrate can be carried out. It is easy to m...
