Embodiment Construction

[0032] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0033] An embodiment of the present invention provides a metal wire repair method for a display substrate, wherein the method includes:

[0034] The breakpoint of the metal wire is laser processed by the laser output laser beam to form a fracture structure. The cross sections of the metal wires on both sides of the fracture structure are respectively formed as smooth slopes, and the slopes are inclined relative to the extending direction of the metal wires on the side. The angle is less than 90 degrees;

[0035] A conductive material is deposited on the fracture structure to form a connection line connecting the metal lines on both sides of the fracture structure.

[0036] like image 3 Shown is a schematic diagram of laser processin...

Abstract

According to the technical scheme, the invention aims at providing a display substrate metal wire repairing method, a lens used for the method and a laser device. The method comprises the steps that the laser device outputs laser beams to conduct laser machining on breaking points of metal wires, a fracture structure is formed, the fracture surfaces of the metal wires on the two sides of the fracture structure are smooth slopes, and the inclination angle of the slopes relative to the extending direction of the metal wires on the sides where the slopes are located is smaller than 90 degrees; electric conduction materials are deposited on the fracture structure, and a connecting line for connecting the metal wires on the two sides of the fracture structure is formed. At the position of a fracture obtained after laser machining, the fracture surfaces are in a smooth slope structure form, the inclination angle of the slopes relative to the extending direction of the metal wires on the sides where the slopes are located is smaller than 90 degrees, when electric conduction materials are deposited during fracture repairing, coating materials can be smoothly deposited in the fracture, the material deposition continuous rate is guaranteed, and the maintaining success rate is increased.

Description

technical field [0001] The invention relates to the technical field of display repair, in particular to a metal wire repair method of a display substrate, a lens and a laser used in the method. Background technique [0002] At present, in the display repair process, the repair of the metal wire fracture is an indispensable process. like figure 1 Shown is a schematic plan view of the metal wire fracture 1, figure 2 A cross-sectional schematic diagram of a metal wire fracture. according to figure 2 , because there is usually a height difference in the fracture, when the existing technology is used for the repair of the metal wire fracture, if the method of laying metal powder directly from both ends of the fracture is adopted, due to the existence of the fracture height difference, the fault position cannot be completely filled. The connection success rate is low, which affects the restoration quality. [0003] Based on this, when repairing metal wire fractures in the p...
