S403, in the through-hole at coordinate in array substrate of the first pixel region, to the first pixel region there are pressures Two signal wires of difference carry out welding.
Specifically, being referred to welding is carried out there are the two of pressure difference signal wire;Laser welder is controlled, to the first metal The corresponding drain line of first pixel region is melted in layer 100, and laser intensity is greater than the transmitted intensity of insulating layer 300, so that The drain line of melting is connect with the storage capacitance line in second metal layer 200;But this method is used to carry out welding to signal wire During, it may cause since laser energy is excessive when penetrating insulating layer 300, cause the splashing of the drain line of melting.
In the present embodiment, in order to solve this problem, through-hole can be reserved with by each pixel region in a insulating layer;Amendment dress It sets after the location information for obtaining the first pixel region where defect, can be existed according to the through-hole of the first pixel region therein Coordinate in array substrate determines the position of through-hole;Specifically, to can be with there are the welding between the two of pressure difference signal wire Be: in the through-hole at coordinate in array substrate of the first pixel region, to the first pixel region there are two letters of pressure difference Number line carries out welding.
It is worth noting that, the welding in the present embodiment is control laser welder, to the first picture in the first metal layer 100 The corresponding drain line in plain region is melted, so that the drain line of melting passes through the storage in the through-hole and second metal layer 200 Capacitor line connection, avoids the generation of splash phenomena in fusion process.
Further, coordinate of the through-hole of the first pixel region in the present embodiment in array substrate includes: the first picture The coordinate of center of the through-hole in plain region in array substrate, wherein the through-hole of the first pixel region is in array substrate Center coordinate, the as coordinate of center of the center of circle of through-hole in array substrate.Specifically, detection device exists It, can be by the through-hole of first pixel region in array base after obtaining coordinate of the through-hole of the first pixel region in array substrate Coordinate on plate is sent to processing unit;Microscope is provided in processing unit in the present embodiment, processing unit control is micro- Mirror amplifies processing at coordinate in array substrate to the through-hole of the first pixel region, so that after processing unit is according to amplification Through-hole, obtain the coordinate of center of the through-hole in array substrate, and the center by the through-hole in array substrate Coordinate be sent to correcting device so that correcting device obtains the coordinate of center of the through-hole in array substrate.
Specifically, to there are the weldings between the two of pressure difference signal wire may is that in the first pixel region in the present embodiment At the coordinate of center of the through-hole in domain in array substrate, to the first pixel region there are two signal wires of pressure difference into Row welding.
Further, in the present embodiment, on gravity direction, second metal layer is located at the top of the first metal layer.It is obtaining After the coordinate for taking center of the through-hole of the first pixel region in array substrate, it can be existed according to the coordinate of the center Fusion point is determined in second metal layer.Specifically, in the present embodiment on vertical direction, by the coordinate of center in the second gold medal Belong to the projected position on layer, as fusion point.
Specifically, to there are the weldings between the two of pressure difference signal wire may is that according to center in the present embodiment Coordinate and fusion point, to the first pixel region, there are two signal wires of pressure difference to carry out welding.
Illustratively, such as in the corresponding the first metal layer 100 of drain line, the through-hole with the first pixel region is obtained in battle array The identical position of the coordinate of center on column substrate, as fusion point;Laser welder is controlled in the present embodiment to first Drain line in metal layer 100 carries out welding, and the drain line of melting passes through in the through-hole and metal layer 300 on insulating layer 300 Storage capacitance line connection.
Wherein, the position where the fusion point and through-hole in correcting device control laser welder aligned metal layer, right Level postpones, and control laser welder releases energy, so that there are two signal wire weldings of pressure difference.
As shown in figure 5, illustrative, the storage capacitance in drain line and second metal layer 200 in the first metal layer 100 Line is connected by insulating layer 300;Specifically, being wherein the drain line of the melting of the first metal layer 100 by the dash area of through-hole.
In the present embodiment, there is insulation between the corresponding metal layer of two signal wires there are pressure difference of the first pixel region Layer, each pixel region are reserved with through-hole in the corresponding position of insulating layer;Location information includes the first pixel region in array Coordinate of the through-hole of coordinate and the first pixel region on substrate in array substrate;Further, the first pixel region is logical Coordinate of the hole in array substrate includes: the coordinate of center of the through-hole of the first pixel region in array substrate;According to The coordinate of center determines fusion point on the corresponding metal layer of two signal wires there are pressure difference of the first pixel region; According to the coordinate and fusion point of center, to the first pixel region there are two signal wires of pressure difference to carry out welding.This Embodiment provide modification method not only make there are between the two of pressure difference signal wire keep voltage it is consistent, realize to defect into Row amendment, also avoids the generation of splash phenomena in fusion process during welding.
Modification method provided by the invention is further described below with reference to Fig. 6, Fig. 6 is amendment provided by the invention The flow diagram three of method, as shown in fig. 6, modification method provided in this embodiment may include:
