Description
Technical field
The present invention relates to liquid crystal display manufacturing technology field, more particularly to a kind of transfer printing board, transfer device, alignment film coating
Method and display panel.
Background technology
Liquid crystal display (Liquid Crystal Display, LCD) has thin fuselage, power saving, radiationless etc. numerous excellent
Point, is widely used, such as TV, computer, mobile phone display screen application.Liquid crystal display is passive luminescent device,
Liquid crystal material itself does not shine, and the liquid crystal display on existing market is largely backlight liquid crystal display comprising liquid crystal
Display panel and backlight module (backlight module).Usual liquid crystal display panel is by color film (Color Filter, CF)
Substrate, is sandwiched in color membrane substrates and thin film transistor (TFT) battle array at thin film transistor (TFT) (Thin Film Transistor, TFT) array substrate
Liquid crystal and sealing glue frame (Sealant) composition between row substrate, moulding process generally comprise：Leading portion array (Array) is made
(thin film transistor base plate and colorized optical filtering ilm substrate are pasted at box (Cell) processing procedure for journey (film, yellow light, etching and stripping), stage casing
Close) and back segment module group assembling processing procedure (driving circuit (IC) is pressed with printed circuit board).
The operation principle of liquid crystal display panel is to place liquid crystal molecule in the parallel glass substrate of two panels, by two
Apply driving voltage on sheet glass substrate and change direction to control liquid crystal molecule, the light refraction of backlight module is out generated into picture
Face；And the premise for guiding ordered liquid crystal molecule to rotate is to make one layer of uniform PI in TFT substrate and CF substrate surfaces
(Polyimide, polyimides) phase matching film is orientated liquid crystal molecule, for the rotation of liquid crystal molecule provides an anchoring
Power.
Currently, industry is coated in TFT substrate and CF thereons there are two types of the modes of PI phase matching films：First, printing type
(Inkjet), second is that transfer-type (Print)；The PI film coating methods of transfer-type have more preferable control PI film precision in contrast
Advantage, especially in the case where existing market trend develops toward Rimless product, the advantages of transfer-type, can more highlight,
One better help can be played for narrow frame product design.
As shown in Figure 1, the PI films coating process of transfer-type by alignment liquid 2 by nozzle 1 specifically, be added drop-wise to scraper first
On roller 3, the transfer printing board for the alignment film printing being coated on transfer wheel 4 is transferred to by the turning handle alignment liquid 2 of doctor roll 3
On (Asahikasei Photosensitive Resin plate, abbreviation APR editions) 5, finally by transfer printing board 5 alignment liquid 2
It is printed onto on display base plate 6, to form alignment film.
Wherein, as shown in Fig. 2, transfer printing board 5 is made of the substrate 7 of specific materials, substrate 7 has many tiny above
Circular concave point 8, to accommodate alignment liquid 2, alignment liquid 2 is first stored in these 8 the insides of concave point, is then transferring these concave points 8
It is extruded to again above display base plate 6 under the pressure of wheel 4, then alignment liquid 2 constantly spreads apart on alignment liquid 2 again, to
Uniformly it is covered with alignment liquid 2 on entire display base plate 6.But under normal circumstances, in direction up and down between circular concave point 8
There can be distance, as shown in Figure 2 distance a and b, the gap that this distance is corresponded on display base plate 6 needs alignment liquid 2 to go to spread
It can just cover and go above, if the landform of display base plate 6 is with respect to out-of-flatness, the diffusion of alignment liquid 2 will be uneven, and then goes out
The now quality problems such as the broken bright spot caused by alignment film film surface unevenness or brightness disproportionation (Mura).Even if in addition, furthering
The distance between concave point 8, as shown in figure 4, make 8 close-packed arrays of concave point on transfer printing board 5, since the shape of round concave point 8 limits,
Between circular concave point 8 or there can be gap, the diffusion of alignment liquid 2 in this corresponding gap still can be by the landform of display base plate 6
Limitation.
So present inventor has found in practical applications：When using existing transfer impact transfer printing alignment liquid 2, often
Entire alignment liquid 2 is caused to spread unevenness since the diffusion length in alignment liquid 2 towards each direction is inhomogenous during processing procedure,
Phase matching film film thickness so as to cause display base plate 6 in each place is inconsistent, and then influences the arrangement uniformity of liquid crystal molecule, makes
It is inhomogenous at translucency, the quality of entire display panel is influenced, the acceptance level in the market of product is influenced, it is good also to reduce product
Rate.
