Description
Technical field
It the utility model is related to field of liquid crystal display, more particularly to a kind of printing transfer plate.
Background technology
At this stage, it is necessary to two sheet glass base up and down by display device in liquid crystal display device (LCD) manufacturing process
PI (Polyimide, polyimides) alignment films are respectively coated in plate, using more ripe wide in liquid crystal display manufacturing
It is flexographic printing techniques.
The formation of alignment films is in two steps：Print upper PI liquid on the glass substrate first, be formed by curing PI films；Then to PI films
Carry out friction orientation.Friction orientation is typically wrapped after friction orientation (rubbing) cloth in glass base using friction (rubbing) roller
The method to be rubbed on plate with certain pressure is realized.By friction orientation cloth tip friction hair (pile) rubbing action,
Groove is formed on the surface of PI films, and PI molecules also have the tendency of to arrange according to friction orientation roller direction, and such PI films just have
There is orientation effect, turn into alignment films.Alignment films make it that liquid crystal molecule is accurately orientated, liquid crystal display device be possible to according to
Design needs to play optically-active effect.
Fig. 1 show the equipment operating diagram of glass substrate PI liquid transfer process, and the wherein curling of transfer plate 106 is arranged on
In print roller 100, rotated with print roller 100, PI liquid is coated with when turning over deputy roller 103, there is transfer projection on transfer plate 106
(pattern) place for, only having transfer projection on transfer plate 106 can just be stained with PI liquid.Glass substrate 101 is in conduction microscope carrier
Horizontal conveyor on 102, when being driven glass substrate 101 to 100 lower section of print roller, a side of transfer plate 106 just contacts
Glass substrate 101, then PI liquid is applied by the rotation of print roller 100 and the horizontal conveyor of conduction microscope carrier 102, transfer plate 106
Cloth makes PI liquid form PI films 107 on glass substrate 101 on glass substrate 101.
A number of mesh is distributed with the transfer projection of transfer plate 106, for storing PI liquid, and by the PI liquid of storage
It is transferred on glass substrate 101.
The each transfer projection set on transfer plate 106 is corresponding with each liquid crystal display figure on glass substrate 101, and its
Size is bigger than the viewing area of liquid crystal display, and purpose ensures that the viewing area of each liquid crystal display figure on glass substrate 101 can be by PI films
107 are completely covered, and the borderline region of the printed pattern of PI films 107 are controlled outside viewing area, to avoid the thicker PI of borderline region
Diaphragm area influences the liquid crystal normal orientation of viewing area.
As shown in Fig. 2 the plan for transfer plate in the prior art.Multiple transfers of regular arrangement on transfer plate 106
Projection 1061.As shown in figure 3, it is profile of the transfer plate in Fig. 2 along print direction.Transfer plate 106 includes substrate 1060 and turned
Projection 1061 is printed, wherein transfer projection 1061 includes transfer projection intermediate region 10611, the and of transfer projection borderline region 10612
Projection interstice coverage 10613 is transferred, corresponds to liquid crystal display graphical display area, non-display area and the interstice coverage of glass substrate respectively.Liquid crystal
Screen graph area is coated with PI liquid, and interstice coverage does not coat PI liquid.
Speed, intrusion when being extruded due to transfer plate 106 with glass substrate 101 are influenced each other, especially at each turn
The process that the borderline region 10612 of print projection 1061 is contacted or separated with glass substrate 101, stress suddenly change cause printing
The PI diaphragm areas of the borderline region in direction occur that thickness is excessive or width is wide and influences the display effect of showing edge, table directly perceived
The PI diaphragm areas on two sides of each liquid crystal display figure have that color is too deep or width is abnormal when now to check substrate printing effect.
Therefore, LCDs is circumferentially oriented film thickness and can cause the orientation of liquid crystal molecule abnormal extremely, shows as periphery color not
Equal phenomenon, reduces product quality and yield；For small-size product, this influence is even more serious.
Utility model content
The utility model provides a kind of transfer plate, to overcome the structure of existing transfer projection to easily cause LCDs
The film that is circumferentially oriented cause the orientation of liquid crystal molecule abnormal extremely, there is the phenomena impair product quality of periphery irregular colour and good
The defects of rate.
