Problems solved by technology

And in order to meet the needs of integration, the wiring often needs to be carried out in the above-mentioned groove, but with repeated bending operations, the material of the flat layer will cause stress to the wiring, so that the wiring breaks, which is not conducive to the reliability of the flexible display panel. sex

Abstract

The invention provides a flexible display panel and a repairing method thereof. On the basis of improving the bending degree, a repairing layer, namely a first laser activated polymer layer, below a circuit layer is arranged; when the circuit layer is completely broken, an activated metal layer can be generated through laser activation to conduct the broken circuit layer, and the repairing function of a circuit is achieved. The method is extremely simple, and pixel units emitting light from the top face cannot be affected; further, a second laser activated polymer layer included can repair a connection line connecting a thin film transistor and the circuit layer.

Description

technical field [0001] The invention relates to the technical field of display panels, in particular to a flexible display panel and a repair method thereof. Background technique [0002] With the advantages of flexible organic light-emitting diode (Organic Light-emitting Diode, OLED) panel due to its wide color gamut, high contrast, large viewing angle, fast response rate, light and thin. In mobile phones, watches, Pads and other application fields, as consumers love large screens, the screen ratio requirements are getting higher and higher. [0003] At present, flexible bending OLED panels mainly include static bending and dynamic bending. The panel can only be bent vertically or horizontally, and the bending direction is relatively limited, and the bending radius is relatively large. In the prior art, in order to improve the bending degree of the display panel, it is often used to form grooves in the multi-layer insulation layer (including buffer layer, gate insulation ...
