Abstract

The invention provides a pixel array and a repairing method for a pixel unit. The pixel array comprises a plurality of pixel units. Each pixel unit comprises a first sub-pixel and a second sub-pixel. The first sub-pixel comprises a first active element and a first pixel electrode electrically connected to the drain electrode of the first active element. The second sub-pixel comprises a second active element and a second pixel electrode electrically connected to the drain electrode of the second active element. The overlapped part of the first pixel electrode and the drain electrode of the second active element is provided with a first capacitor. The present invention also provides a repairing method for a pixel unit.

Description

technical field [0001] The invention relates to a pixel array and a pixel unit repairing method, in particular to a pixel array and a pixel unit repairing method which are beneficial to dark spots. Background technique [0002] In recent years, although flat panel display technology has matured, some dot defects will inevitably occur in the manufacturing process of the components of the display panel, such as the active device array substrate. Generally speaking, if the aforementioned dot defects can be repaired into dark dots by means of repairing, these defective display panels can be discarded without scrapping. [0003] The current repairing method of pixel unit usually adopts laser welding (laser welding) and laser cutting (laser cutting) to carry out, so as to connect the pixel electrode to the common potential, and then achieve the dark spot effect. However, since the structure of the display panel tends to be complicated, the pixel electrodes may still not be reliab...
