Description
Technical field
The present invention relates to field of display technology more particularly to a kind of sealants, the production method of liquid crystal display panel and liquid
LCD panel.
Background technique
With the development of display technology, the planes such as liquid crystal display (Liquid Crystal Display, LCD) display dress
It sets because having many advantages, such as that high image quality, power saving, fuselage is thin and has a wide range of application, and is widely used in mobile phone, TV, a number
The various consumer electrical products such as word assistant, digital camera, laptop, desktop computer, become the master in display device
Stream.
Liquid crystal display device on existing market is largely backlight liquid crystal display comprising liquid crystal display panel
(TFT-LCD) and backlight module (backlight module).The working principle of liquid crystal display panel is the glass parallel in two panels
Place liquid crystal molecule in glass substrate, there are many tiny electric wire vertically and horizontally among two panels glass substrate, by be powered with
It is no to change direction to control liquid crystal molecule, the light refraction of backlight module is come out and generates picture.
Usual liquid crystal display panel is by color film (CF, Color Filter) substrate, thin film transistor (TFT) (TFT, Thin Film
Transistor) array substrate, the liquid crystal (LC, the Liquid that are sandwiched between color membrane substrates and thin-film transistor array base-plate
Crystal) and sealant (Sealant) forms.In the production of liquid crystal display panel, need in thin-film transistor array base-plate
Or dispenser method and sealant on color membrane substrates, then two substrates are carried out to group, then sealant is solidified, wherein envelope frame
The effect of glue is adhering film transistor (TFT) array substrate and color membrane substrates, and protects intermediate liquid crystal not by outside air and water
Influence.
Sealant generally includes glue ontology and is blended in be used to support liquid crystal cell thick (Cell Gap) in glue ontology
Multiple spacers.It is different in order to facilitate the centralized purchasing of material, management and impregnation operation in liquid crystal display panel manufacturing
Spacer of the product of liquid crystal cell thickness design under liquid crystal drop in (ODF) processing procedure in sealant is all made of the same ruler of same material
It is very little, as liquid crystal cell thickness be 3.5 μm and 3.8 μm panel sealant the use of length is 4.0 μm column glass partition object.
Fig. 1 is a kind of existing structural schematic diagram of liquid crystal display panel, and the liquid crystal display panel includes being oppositely arranged
CF substrate 100 and TFT substrate 200, the liquid crystal layer 400 between the CF substrate 100 and TFT substrate 200 and be set to institute
The sealant 300 of 400 periphery of liquid crystal layer is stated between CF substrate 100 and TFT substrate 200 and is located at, the sealant 300 is wrapped
The multiple column spacers 320 for including glue ontology 310 and being blended in glue ontology 310.
The production method of above-mentioned liquid crystal display panel is usual are as follows: in 200 dispenser method material of CF substrate 100 and TFT substrate
After coating sealant 300, CF substrate 100 and TFT substrate 200 are placed in vacuum environment and carry out obtaining a liquid crystal to group
Then liquid crystal display panel is placed in atmospheric environment by display panel, make the two sides of the liquid crystal display panel by big
The inside side compression of the effect of atmospheric pressure Fp finally makes liquid crystal so that the column spacer 320 in sealant 300 be made to be compressed
Layer 400 be compressed to one expected from thickness.
In above-mentioned compression process, since the compression ratio of column spacer 320 is limited, multiple column spacers 320 are inclined to
Topple in towards different directions, distribution is mixed and disorderly, and decrement is uneven and compression ratio is difficult to control, it is difficult to guarantee the side of liquid crystal layer 400
The defects of whether edge box thick (Edge Gap) is reasonable, be easy to cause periphery brightness irregularities (Mura), ear light leakage (Defect)；
For the thick lesser liquid crystal display panel of liquid crystal cell, it may also need to apply other active forces in the production process in liquid crystal
Show on panel, liquid crystal cell is further compressed, due to the pressure mistake of the receiving of column spacer 320 in compression process
Greatly, it is easy to scratch the route in TFT substrate 200, causes yield loss (Loss).
