As shown in Figure 1, it is the structural representation of the Trackpad 10 of the utility model one preferred embodiment.
Trackpad 10 comprises: optical cement 500, and superposes cover-plate glass 100, first conductive film 200 of setting, polarization matrix 300 and the second conductive film 400 successively.Polarization matrix 300 is made for polyvinyl alcohol (PVA) (PVA).
Cover-plate glass 100 covers the first conductive film 200, and its size is greater than the size of the first conductive film 200, to make the periphery of cover-plate glass 100 can paste mutually with the shell of display module, supports Trackpad 10.
First conductive film 200 is printed with the first electrode 210, second conductive film 400 and is printed with the second electrode 410, and the first electrode 210 and the second electrode 410 lay respectively at side opposing with polarization matrix 300 on the first conductive film 200 and the second conductive film 400.
Cover-plate glass 100, first conductive film 200, polarization matrix 300 and the second conductive film 400 are all connected to each other by optical cement 500.Wherein, do not show in optical cement 500 figure between the first conductive film 200, polarization matrix 300 and the second conductive film 400.Be coated on the first conductive film 200 identical with the first conductive film 200 for the size of the optical cement 500 of connection cover glass sheet 100, and cover the first conductive film 200.
See also Fig. 2, it is the structural representation of the liquid crystal display module 20 of the Trackpad 10 shown in application drawing 1.
Liquid crystal display module 20 comprises: shell 250, and superposes Trackpad 10, first glass substrate 210, second glass substrate 220 of setting, polaroid 230 and backlight assembly 240 successively.Trackpad 10, first glass substrate 210, second glass substrate 220, polaroid 230 and backlight assembly 240 are all placed in shell 250.
Trackpad 10 is arranged in shell 250, and the periphery of the cover-plate glass 100 of Trackpad 10 abuts with shell 250.Trackpad 10 is arranged on the first glass substrate 210 by optical cement 500.Concrete optical cement 500 is between second conductive film 400 and the first glass substrate 210 of Trackpad 10, and size is identical with the second conductive film 400, and covers the second conductive film 400.
When producing above-mentioned Trackpad 10, first the first conductive film 200, polarization matrix 300, second conductive film 400 are pasted compound by optical cement 500, and cut into the applicable follow-up size printed electrode.Adopt exposure imaging processing procedure, on the first conductive film 200 and the second conductive film 400, the side opposing with polarization matrix 300 prints the first electrode 210 and the second electrode 410 respectively.Then optical cement 500 is coated on the side the first conductive film 200, second conductive film 400 being printed with the first electrode 210 and the second electrode 410.Again that the first conductive film 200 of compound, polarization matrix 300, second conductive film 400 is die-cut, match to make the size of its size and shell to be assembled.Afterwards, binding flexible PCB (FPC), detects its electrical property, and cover-plate glass 100 and the first conductive film 200 is fitted.During the liquid crystal display module 20 of the above-mentioned Trackpad 10 of production application, only again Trackpad 10 need be fitted by optical cement 500 and the first glass substrate 210 and just can.
Polarization matrix 300 is arranged between the first conductive film 200 and the second conductive film 400 by above-mentioned Trackpad 10; form the Trackpad 10 with polarization function, and utilize the first conductive film 200 and the second conductive film 400 to replace being arranged at the protective seam protection polarization matrix 300 of conventional polarizers both sides.Like this; the functional layer of the functional layer of conventional polarizers and conventional Trackpad combines by Trackpad 10; combine by polarization matrix 300, first conductive film 200 and the second conductive film 400; and the polaroid replacing conventional Trackpad and abut with conventional Trackpad; both the thickness of the liquid crystal display module 20 with Trackpad 10 had been reduced; make it more frivolous, again can available protecting polarization matrix 300, prevent it from deformation occurring.The liquid crystal display module 20 with Trackpad 10 also reduces the loss that the light that sends from backlight assembly 240 is propagated between multilayer film, improves the brightness of the liquid crystal display module 20 of this Trackpad 10 of application.In addition, polarization matrix 300 is arranged at the laminating number of times also reducing liquid crystal display module 20 multilayer film of this Trackpad 10 of production application between the first conductive film 200 and the second conductive film 400, simplifies production process, improve production efficiency.
For connect the first conductive film 200 and cover-plate glass 100 and the first glass substrate 210 and the optical cement 500 of Trackpad 10 size respectively with the first conductive film 200 and the second conductive film 400 identical, after prevent from fitting cover-plate glass 100 and the first glass substrate 210, the edge of the first conductive film 200 and the second conductive film 400 produces bubble.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
