Description
Technical field
The present invention relates to a kind of LCD and manufacture method thereof, particularly a kind of with light polarizing film and incorporate display panels of display panels and manufacture method thereof.
Background technology
In recent years, LCD (liquid crystal display, abbreviation LCD) production development is very swift and violent, more and more high-quality LCD are gone on the market gradually, its application is also constantly widened, but many problems also occurred simultaneously, wherein a series of problems of bringing of the attaching of light polarizing film (light polarizing film arizing Film is called for short POL) are to cause one of not high key factor of display panels light transmission rate and yields.
In the prior art, display panels and light polarizing film making are normally separately carried out, light polarizing film is directly provided by light polarizing film manufacturer, display panels finish cut apart and to box technology after, directly in subsequent technique, finish light polarizing film and attach, be about to make good light polarizing film (going up light polarizing film and following light polarizing film) and be attached to the display panels surface.In the actual production, there is multiple adverse effect in this technology of prior art to the display effect of display panels, causes yields not high, and production cost is risen, and is embodied in:
(1) because light polarizing film is made and the attaching process in all have stretching process, thereby the back light polarizing film exists shrinkage phenomenon on the panel attaching to, and makes the panel that attaches after the light polarizing film may have buckling phenomenon;
(2) in attaching the light polarizing film process, exist alignment situation, can influence display effect if alignment situation is bad;
(3) consider that for design the light polarizing film of attaching has increased some contact layers, these contact layers influence light transmission rate, and then influence display effect;
(4) the light polarizing film skin adheres to one deck adhesive agent, and can there be phenomenons such as aging in this adhesive agent under temperature higher and service time of longer situation;
(5) when attaching light polarizing film, will there be bubble phenomenon, then can brings unnecessary foreign matter when peeling off the diaphragm in the light polarizing film outside, the yields of display panels is had considerable influence follow-up if light polarizing film trails; When attaching light polarizing film precision is not enough, can influence display effect;
(6) present, light polarizing film normally adopts 9 layers of form, is respectively special-shaped film (Release film), adhesive coating (PSA), light layer of compensation (WV DLC), supporting layer (TAC Film), polarizing layer (PVA Film), supporting layer (TAC Film), antiglare layer (AG Layer), low reflection layer (LR/AR Layer) and diaphragm (Protective Film); The manufacture craft of light polarizing film adopts precuring (Pre-cure) usually, extends ﹠amp; Expand (Laminating), deposition (Coating), technologies such as cutting (Cutting), inspection and packing,, complex process many owing to the number of plies is difficult to effective control, causes yields not high, and production cost is risen.In addition, because the number of plies of deposited film is more, the light transmission rate of display panels there is great adverse effect.
Summary of the invention
