Abstract
The invention discloses a repair method of flaws on a liquid crystal panel and the method contains the follow steps: a), a defect is positioned by a light blockage pattern on a glass basal plate; b), a spray area which at least partly covers the defect is defined on the glass basal plate; c), repair fluid is sprayed to the spray area; and d), hardening procedure is conducted to harden the repair fluid. Through the method, repair can be done to defects of the light blockage pattern in the manufacturing process of the liquid crystal panel, thus improving the rate of good quality of liquid crystal panels.
Description
Technical field
The present invention relates to the flaw repairing technique of liquid crystal panel, be meant that especially advanced row sprays the flaw mending method that repair liquid makes it a kind of liquid crystal panel of hardening again.
Background technology
Existing liquid crystal panel when conductive pattern (or being electrode pattern) wherein is set on for liquid crystal board, is to lay the photoresistance pattern on glass substrate in the process of making, and carries out etching again.
And aforesaid way, very strict to environment requirement, if environment is not controlled well, there are dust or liquid to attach on the glass substrate and cause, then the formed pattern of photoresistance promptly has the generation of flaw point, and the generation of flaw point means that promptly the bad point (bright spot or dim spot) on the liquid crystal panel produces.
Present way is after the liquid crystal panel manufacturing is finished, and detects, and after finding bad point, shines with laser repairing again, makes this evil idea point become dim spot, does not have the problem of fixing bright certain look.
Yet above-mentioned laser preparation method still can not allow bad some reparation become the state of operate as normal.
Summary of the invention
Fundamental purpose of the present invention provides a kind of flaw mending method of liquid crystal panel, its can processing procedure to liquid crystal panel in, the flaw point of photoresistance pattern is repaired.
An of the present invention purpose provides a kind of flaw mending method of liquid crystal panel, and it can repair possible bad point, and then increased the yield of liquid crystal panel in advance.
In order to reach aforementioned purpose, according to the flaw mending method of a kind of liquid crystal panel provided by the present invention, include the following step: a) the photoresistance pattern on a glass substrate is oriented flaw point; B) definition one sprays the zone and contains this flaw point in the part at least on this glass substrate; C) this is sprayed the zone and spray repair liquid, repair liquid is sprayed in this spray the zone; And d) carries out hardening process and make this repair liquid sclerosis.By this, can processing procedure to liquid crystal panel in, the flaw point of photoresistance pattern is repaired, and and then has increased the yield of liquid crystal panel.

Embodiment
In order to describe technical characterstic of the present invention place in detail, lift a following preferred embodiment now and cooperate graphic explanation as after, wherein:
As shown in Figures 1 to 4, the flaw mending method of a kind of liquid crystal panel that a preferred embodiment of the present invention provided mainly has the following step:
A) the photoresistance pattern 12 on a glass substrate 11 is oriented a flaw point 14.As shown in Figure 1, on this glass substrate 11, have the wiring 121 that forms by this photoresistance pattern 12, and be positioned at the flaw point 14 on this glass substrate 11, this flaw point 14 promptly be this wiring 121 not complete be provided with form.
B) on this glass substrate 11 definition one spray the zone 16 at least the part contain this flaw point 14.As shown in Figure 2, be that definition one sprays zone 16 on this glass substrate 11, wherein this to spray the zone 16 be to contain the zone that this flaw point 14 is contained fully, among Fig. 2, be to express this to spray regional 16 are zones greater than this flaw point 14.Spray the situation generation that zone 16 equals the zone of flaw point 14 and in fact also may have.And also might spray zone 16 and only be covered by this flaw point 14 in the part.It focuses on this and sprays the normal position that this wiring 121 must be contained in zone 16.
C) this is sprayed zone 16 and spray repair liquid 161, repair liquid 161 is sprayed in this spray zone 16.Its state as shown in Figure 3, and this repair liquid 161 is to be photoresistance liquid in present embodiment.
D) carry out hardening process and make this repair liquid 161 sclerosis.This hardening process is to can be irradiation ultraviolet radiation or shine infrared ray to make this repair liquid 161 sclerosis.
So far, the repair liquid 161 after the sclerosis promptly forms a photoresist layer, and mend at the position that disconnects on 121 of will connecting up, and reaches the effect of repairing.
The present invention can more include:
Step e) defines at least one removal zone 18 on this glass substrate 11, this removal zone 18 is that the part joins and sprays zone 16 in this at least, and this is removed regional 18 irradiating laser light, the sclerosis repair liquid 161 in this removal zone 18 can be removed by this.As shown in Figure 4, be to define two to remove zone 18 in the present embodiment, should removals zone 18 be to spray zone 16 respectively wherein less than this, and part or all contain this and spray regional 16.Again, this two removals zone 18 is local each other overlap (also can adjacently being provided with).And respectively this removal zone 18 is with respect to these 121 unnecessary parts that connect up.
By by increasing this step e), can spray under the excessive situation in zone 16 at this, this is sprayed the redundance of repair liquid 161 is removed after the sclerosis in the zone 16.Wiring 121 after feasible the repairing is more near perfect condition, and its state as shown in Figure 5.
By this, the present invention can repair the flaw point of the photoresistance pattern in the liquid crystal panel manufacture process.It is with possible i.e. reparation in advance of the bad stage of point etched before, makes in the processing procedure of back segment, exempted the photoresistance pattern flaw point all problems that may cause, and then increased the yield of liquid crystal panel.
