Problems solved by technology

Among them, each pixel actively driven is equipped with a low-temperature polysilicon thin-film transistor (LTP-Si TFT) with switching function. In actual production, due to factors such as TFT leakage, the brightness of the sub-pixel of the OLED device will be too large, thus produce bright spots
In the prior art, methods of cutting or shielding are often used to deal with sub-pixel bright spots in sub-pixel OLED devices, but in the implementation process, the process is complicated, and it will also affect the aperture ratio and yield of the device

Abstract

The invention provides an organic light-emitting panel repairing method. The organic light-emitting panel repairing method comprises the steps of locating the positions of sub-pixels where bright spots in a panel are located, adopting a mask plate to shade the region, located outside the sub-pixels where the bright spots are located, of the panel and using UV light for irradiating organic light-emitting regions of the sub-pixels where the bright spots are located.

Description

Technical field [0001] The invention relates to a method for repairing an organic light-emitting panel, in particular to a method for repairing bright spots in an OLED panel. Background technique [0002] The organic light-emitting device utilizes an electrically excited organic fluorescent compound to emit light, and it has a cathode and an anode with an organic film composed of an organic compound in between. When a voltage is applied to the cathode and anode, in the electrode with a positive voltage, holes migrate to the organic light-emitting area through the hole transport layer (HTL), and in the electrode with a negative voltage, electrons migrate to the electrode through the electron transport layer (ETL) In the organic light-emitting area, holes and electrons recombine in the organic light-emitting area to generate excitons. The excitons are excited to emit light and provide a light source for OLED display. [0003] The characteristic of OLED is that it emits light by itse...
