Refer to Fig. 1 and Fig. 2, the positioning component 100 of embodiment of the present invention, the ito thin film 200 for touch-screen exposes.This positioning component 100 comprises substrate 110, tack coat 120 and reference column 130.Substrate 110 is as the bearing part of ito thin film 200.Tack coat 120 is for pasting ito thin film 200, and it can remove after ito thin film 200 exposes.Reference column 130 is for positioning baseplate 110.
Substrate 110 has first surface 111 and the second surface 113 relative with first surface 111.Substrate 110 can be thin web, plastic plate, resin plate etc.In addition, substrate 110 can be transparency carrier, also can be opaque substrate.The thickness of substrate 110 is less than or equal to 1.1 millimeters, so that be arranged in the exposure worktable (not shown) of exposure machine.Specifically in the illustrated embodiment, substrate 110 is glass plate, and its thickness is 1.1 millimeters.
In other embodiments, substrate 110 is poly methyl methacrylate plastic plate, and its thickness is 1 millimeter.
Tack coat 120 is located on the first surface 111 of substrate 110.Tack coat 120 can be paper-like dung, also can be the curable glue be coated on substrate 110.It should be noted that, tack coat 120 can be covered with the whole surface of ito thin film 200, and also can be interval and arrange, such as, tack coat 120 is located at surrounding and the medium position of ito thin film 200, to save tack coat 120, and also easily removes after exposure.
Specifically in the illustrated embodiment, tack coat 120 is double faced adhesive tape.By double faced adhesive tape, ito thin film 200 is attached on the first surface 111 of substrate 110.
In other embodiments, tack coat 120 is water-soluble adhesive layer, and when substrate 110 is positioned in water, tack coat 120 is dissolved in the water, and after making exposure, ito thin film 200 is separated with substrate 110.
In another embodiment, tack coat 120 is UV glue water layer, and substrate 110 is transparency carrier 110; When adopting UV-irradiation substrate 110, tack coat 120 solubilized, after making exposure, ito thin film 200 is separated with substrate 110.
Reference column 130 is multiple, and its periphery around substrate 110 is arranged, and multiple reference column 130 abuts against with the periphery of substrate 110, thus positioning baseplate 110.Specifically in the illustrated embodiment, ito thin film 200 is rectangle, and its four limit arranges a reference column 130 respectively.Certainly, the every of ito thin film 200 also can arrange two and plural reference column 130.
Further, in order to the ito thin film 200 making exposure machine be suitable for different size exposes, multiple reference column 130 is located on exposure worktable slidably, according to the position of the dimension adjustable reference column 130 of substrate 110, reference column 130 is tightly abutted with the periphery of substrate 110.
Further, reference column 130 is elastic, and reference column 130 abuts with the periphery of substrate 110, and elastic deformation occurs reference column 130.There is slight deformation because reference column 130 is subject to the extruding of substrate 110, so that the scale error between adjustment substrate 110 and location, be convenient to positioning baseplate 110 is installed.
Wherein, ito thin film 200 is attached on the first surface 111 of substrate 110 by tack coat 120; Substrate 110 is for being positioned over exposure worktable, and the second surface 113 of substrate 110 is connected with exposure worktable.

Refer to Fig. 1 to Fig. 3, the ito thin film exposure method of this touch-screen comprises the steps S201 ~ S204.
Step S201, is adhered to ito thin film 200 to be exposed on the first surface 111 of substrate 110 by tack coat 120.Such as, when tack coat 120 is double faced adhesive tape, first double faced adhesive tape can will be sticked on ito thin film 200, then ito thin film 200 is pasted onto on substrate 110, or, first by sticking double faced adhesive tape on substrate 110, then ito thin film 200 to be pasted onto on substrate 110.When tack coat 120 be water-soluble adhesive layer or UV glue water layer time, can first water soluble glue or ultraviolet glue be coated on the first surface 111 of substrate 110, then ITO be attached on substrate 110 and solidify water soluble glue or ultraviolet glue.
Step S202, is positioned over substrate 110 on exposure worktable, and adopts multiple reference column 130 positioning baseplate 110.When exposure worktable is provided with multiple pilot hole, first can plug reference column 130 in a partial hole wherein, then put substrate 110, then plug other a part of reference column 130 according to the size of substrate 110, thus select different pilot holes according to the different size of substrate 110.
Step S203, sticks light shield, exposes ito thin film 200.When employing glass plate is as on substrate 110, now light shield can adopt glass light shield.Because the illumination precision of glass light shield is higher, the exposure accuracy of ito thin film can be improved, and glass light shield is applicable to the higher board of precision.
Step S204, is separated the ito thin film 200 after exposure with substrate 110.When tack coat 120 is double faced adhesive tape, directly can tear double faced adhesive tape, ito thin film 200 is separated with substrate 110.When tack coat 120 is water-soluble adhesive layer, when being positioned in water by substrate 110, tack coat 120 is dissolved in the water, and after making exposure, ito thin film 200 is separated with substrate 110.When tack coat 120 is UV glue water layer, substrate 110 is transparency carrier 110, and adopt UV-irradiation substrate 110, tack coat 120 dissolves, and the ito thin film after exposure 200 is separated with substrate 110.
Compared to ito thin film 200 exposure method of traditional touch-screen, ito thin film 200 exposure method of above-mentioned touch-screen at least has the following advantages:
(1) above-mentioned ito thin film 200 exposure method adopts tack coat 120 to be attached on substrate 110 by ito thin film 200, and adopts reference column 130 abut substrate 110 and locate, and ito thin film 200 can not be rocked because hardness is not high, thus improves the precision of exposure.Such as, adopt ito thin film 200 exposure method of traditional touch-screen, its exposure accuracy only can accomplish 60 microns, if but adopt above-mentioned ito thin film exposure method, then exposure accuracy can accomplish 30 microns.
(2) after above-mentioned ito thin film 200 exposure method adopts substrate 110 to locate ITO, without the need to making pilot hole on ito thin film 200, and at the good ito thin film 200 of exposure machine outside fix, thus the time shutter can be saved when locating, enhancing productivity.Such as, adopt ito thin film 200 exposure method of traditional touch-screen, even if adopt pipelining, per hourly only can produce 60, if but adopt above-mentioned ito thin film exposure method, then per hourly reach 120.
(3) adopt the locator meams of above-mentioned positioning component 100, directly the production line for the production of color filter film, Thin Film Transistor (TFT) slightly can be changed, just can be used for exposure I TO film 200.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
