Repair method and device for flexible display panel and flexible display panel

Abstract

The invention discloses a repair method and device for a flexible display panel and the flexible display panel. The repair method for the flexible display panel comprises the steps of providing a substrate, wherein the substrate comprises a first surface and a second surface which are oppositely arranged; forming a flexible substrate on the first surface, wherein the flexible substrate comprises aplurality of bubbles which protrude along the direction far away from the substrate; forming an active layer on the flexible substrate, wherein the active layer covers the plurality of bubbles; forming a gate on the surface, far away from the flexible substrate, of the active layer; carrying out laser irradiation in an area, covered with the bubbles, of the gate to form a through groove which penetrates through the active layer, the gate and the flexible substrate; and dropwise adding a metal solution to the through groove and solidifying the metal solution to form conductive connectors, wherein the plurality of conductive connectors are electrically connected with the active layer at two sides of the through groove and are insulated with the gate. According to the repair method for the flexible display panel, the problem of poor display performance caused by the bubbles of the flexible display panel can be solved, so that the production yield of the flexible display panel is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of flexible display, in particular to a method for repairing a flexible display panel, a device thereof, and a flexible display panel. Background technique [0002] With the advancement of flexible display technology, in the flexible display panel industry, the preparation of high-performance flexible displays has gradually become a research and development hotspot for enterprises and various research institutions. The structure of the flexible display panel is different from the traditional glass-based display panel. The base of the flexible display panel uses organic materials as the substrate. During the preparation process of the substrate of the flexible display panel, it is necessary to coat and solidify the liquid organic matter. Since the organic matter is easy to introduce air bubbles when it is in a liquid state, there are also a large number of air bubbles in the cured substrate. These b...
