Abstract

The invention relates to the display technology field and especially relates to a backboard, a display panel and a repairing method of an abnormal light emitting diode. Problems that when an abnormallight-emitting diode is repaired or replaced, a process is complex, cost is high, and damages to an active matrix of a backboard are large in a correlation technology are solved. The invention provides the backboard. The backboard comprises a plurality of sub-pixel regions. Each sub-pixel region comprises a light emitting region and a non-light-emitting region. The backboard comprises pixel driving circuits which are arranged on a substrate and located in each sub-pixel region, and driving electrodes which are arranged on one sides, far away from the substrate, of the pixel driving circuits and located in each light-emitting region. Each driving electrode comprises a first electrode, and the first electrode is electrically connected with the pixel driving circuit. The backboard further comprises at least two fixing portions arranged in each non-light-emitting region, and the at least two fixing portions are not overlapped in a thickness direction of the substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a repair method for a backplane, a display panel and an abnormal light-emitting diode. Background technique [0002] The size of the light-emitting diodes used in the micro-light-emitting diode display device is on the micron level, and it has the characteristics of independent control of the picture, independent light-emitting control, high brightness, low power consumption, ultra-high resolution and high color saturation. It will become one of the hot spots in the development of display technology in the future. Contents of the invention [0003] The main purpose of the present invention is to provide a method for repairing the backplane, the display panel and the abnormal light-emitting diodes. The method is used to solve the problems in the related art that the process of repairing or replacing the abnormal light-emitting diode is relatively complicated, the cost is high,...
