Problems solved by technology

At present, there are also repairing equipment for feeding, but because the amount of feeding is required to be within the micron level, the repairing equipment requires high precision and high cost
Especially for the experimental line or small batch research and development, the cost of using this kind of repair equipment is very high
Moreover, the feeding equipment has very strict requirements on the viscosity and other characteristics of the slurry itself, and the maintenance and cleaning of the feeding system are also relatively difficult.

Embodiment Construction

[0015] The present invention is described in detail below in conjunction with accompanying drawing:

[0016] refer to figure 1 , first check the electrode through the inspection machine, find out the open circuit electrode that needs to be repaired, and record the X and Y coordinates of the open circuit 1.

[0017] refer to figure 2 , 3 , 4. Place the glass substrate 2 that needs to be repaired by electrode disconnection on the table 3 that can be fixed or vacuum-adsorbed, and the rubber gasket 4 for placing the glass substrate 2 is installed on the table 3, and the glass is fixed by the slot 5. The substrate 2 is fixed to ensure the fixed position of the glass substrate 2, which is more convenient to operate. Move the support with the stencil 6 into the table top 3, adjust the support so that the two sides of the stencil 6 are respectively parallel to the two sides of the glass substrate 2, and the length of the screen used for printing on the stencil 6 is preferably grea...

Abstract

The invention provides a repair method for broken electrode of plasma screen. Wherein, lying flat the glass base plate to be repaired on table top fit to fix or vacuum sorption to make two sides of missing printed plate parallel to right-angle sides of said glass base plate; labeling on the missing printed plate with small electrode slurry according to found defect coordinate; using screen printing method of small area to coat the slurry on area contained broken wire; sintering and repairing the broken wire with slurry by laser repair machine. This invention needs no costly feeding device, and has well repair effect.

Description

technical field [0001] The invention belongs to the field of flat panel display technology, and in particular relates to a method for repairing bus electrodes (hereinafter referred to as Bus electrodes) and address electrodes (hereinafter referred to as Add electrodes) of a plasma display screen (hereinafter referred to as PDP). Background technique [0002] The PDP emits light by exciting the fluorescent powder through the vacuum ultraviolet rays generated by the gas discharge. The mainstream three-electrode surface discharge PDP structure is mainly composed of front and rear glass substrates, on which Bus electrodes and Add electrodes are respectively fabricated. The main way of PDP work is through the electrodes on the upper and lower plates. Therefore, the production of Bus electrodes and Add electrodes is a key process of PDP production, and intact electrodes are the prerequisite for ensuring the normal operation of PDP. [0003] At present, in order to improve the re...
