Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Seeing also 1 and Fig. 2, the embodiment of the present invention provides the attaching method of a kind of polaroid, is applied to liquid crystal display
In device processing procedure.The attaching method of described polaroid includes:
Step1: substrate 1 is inserted polarizer sheet sticking machine；
Step2: judge that described substrate 1 is the most qualified by described polarizer sheet sticking machine；
Step3: polaroid 2 is inserted described polarizer sheet sticking machine；
Step4: judge that described polaroid 2 is the most qualified by described polarizer sheet sticking machine；
Step5: if the described substrate 1 2-in-1 lattice of qualified and described polaroid, then attach described polaroid 2 to described substrate
1。
In the present embodiment, first described substrate 1 and described polaroid 2 are made whether due to described polarizer sheet sticking chance
Qualified judgement, when the described substrate 1 2-in-1 lattice of qualified and described polaroid, attaches described polaroid 2 to described substrate 1, therefore
The attaching method of described polaroid 2 can get rid of underproof described substrate 1 and described polaroid 2, effectively management and control institute in time
State the attaching precision of polaroid 2.So, the patch of the polaroid attached is carried out by the attaching method of polaroid described in the present embodiment
Attached precision is high, yields is high.
Meanwhile, the most qualified of described substrate 1 is judged action and the judgement action the most qualified to described polaroid 2
Be carried out separately, therefore, it is possible to exactly, quickly determine that underproof is polaroid or substrate, and quickly arrange
Remove, thus be conducive to attaching being smoothed out of operation, and can the attaching precision of effective polaroid 2 described in management and control.
It should be appreciated that in the present embodiment, step Step1 and step Step2 are provided for qualified described substrate
1, step Step3 and step Step4 are provided for qualified described polaroid 2, so step Step1 and step Step2 can
To carry out with step Step3 and step Step4 simultaneously, or prior to step Step3 and step Step4, or it is later than step
Step3 and step Step4.
Described substrate 1 usually glass substrate.
