Abstract

The invention provides an array substrate and a data line breakpoint repair method thereof and a display device. The array substrate comprises an underlying substrate and a first metal layer and a source and drain electrode layer which are sequentially stacked on the underlying substrate. A plurality of data lines are arranged at intervals in the source and drain electrode layer. A plurality of repair lines are spaced in the first metal layer. At least two repair sub-line segments are spaced on the repair lines. The repair sub-line segments extend from the repair lines to the projection position of the data lines on the first metal layer in the thickness direction of the array substrate and insulated from the data lines.The repair sub-line segmentsare connected with the two ends of the breakpoint when the breakpoint of the data lines occurs so as to complete the repair of the breakpoint of the data lines. Meanwhile, the repair linesare arranged on the first metal layer so that the space of the array substrate occupied by the repair lines is reduced and the film layer structure of the array substrate is simplified.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a method for repairing breakpoints of data lines thereof, and a display device. Background technique [0002] Active-matrix organic light-emitting diodes (AMOLEDs) have developed rapidly because of their unique advantages. The array substrate used for AMOLED is mainly Low Temperature Poly-silicon (LTPS) array substrate. During the production process of LTPS array substrate, it is difficult to ensure the uniformity of the formed large-area polycrystalline silicon semiconductor, which is embodied in the threshold voltage drift. . In order to solve the problem of poor homogeneity of AMOLED LTPS polysilicon, the sub-pixel drive circuit of AMOLED LTPS array substrate needs to use a pixel compensation circuit to offset the influence of threshold voltage drift. [0003] The current mainstream pixel compensation circuit is designed for 7T1C. In order t...
