Below in conjunction with Fig. 3 and Fig. 4 the structure of described first polaroid 21 and second polaroid 23 is described.
See also Fig. 3, the diagrammatic cross-section of the polaroid that it provides for the utility model embodiment.In the utility model, polaroid shown in Figure 3 can be used as above-mentioned first polaroid 21 and/or second polaroid 23.
Described polaroid has sandwich construction, and it comprises barrier film 31, pressure-sensitive adhesive layer 32, polarisation main body 33, first tack coat 34, light shield layer 35, second tack coat 36 and the diaphragm 37 that is cascading.
Wherein, described polarisation main body 33 comprises polarisation dielectric layer 331 and first supporting layer 332 and second supporting layer 333 that are separately positioned on described polarisation dielectric layer 331 both sides.Can making of described polarisation dielectric layer 331 by polyvinyl alcohol (PVA) (PVA), it can be described as the PVA light polarizing film usually; Described first supporting layer 332 and described second supporting layer 333 can be made by Triafol T (TAC), and it can be described as TAC sheet base usually.
See also Fig. 4, it is the planar structure synoptic diagram of the light shield layer 35 in the polaroid shown in Figure 3.Described light shield layer 35 (shown in the dash area among Fig. 4) can adopt the wire printing material of shading and make by silk screen printing process, and it can comprise the first silk-screen layer 351 and the second silk-screen layer 352.The thickness of the described first silk-screen layer 351 and the second silk-screen layer 352 can be decided according to the actual requirements.In fact, owing to adopt silk screen printing process, the described first silk-screen layer 351 and the second silk-screen layer 352 can be done extremely thinly (such as reaching micron dimension).In the present embodiment, the thickness of the described first silk-screen layer 351 and the second silk-screen layer 352 can be for 1 micron～10 microns, such as about 5 microns.In addition, described light shield layer 35 can be a frame shape structure, particularly, as shown in Figure 4, the regional in the central opening that can etch a printing opacity of described light shield layer 35, and described opening is corresponding with the viewing area of described liquid crystal panel 22, that is, the light screening material of described light shield layer 35 is only corresponding to be arranged on around the viewing area of described liquid crystal panel 22.Therefore, when described polaroid was conformed to the liquid crystal panel 22 of above-mentioned liquid crystal display module 20, described light shield layer 35 can effectively block the viewing area light on every side of described liquid crystal panel 22, thereby avoided described liquid crystal display module 20 to produce light leaks.Certainly, when the viewing area of described liquid crystal panel 22 when being circular or oval, described light shield layer 35 can have a ring texture accordingly.
Described pressure-sensitive adhesive layer 32 is used to provide contact adhesive to realize the mutual applying between described polaroid and the liquid crystal panel.Described contact adhesive can have the water-soluble conducting polymkeric substance.Described barrier film 31 is attached to described pressure-sensitive adhesive layer 32 surfaces usually.But, it should be noted that when described polaroid is fitted in described liquid crystal panel 22 surfaces by described pressure-sensitive adhesive layer 32, described barrier film 31 need be removed.Described barrier film 31 may produce static when removing, yet, owing to have the water-soluble conducting polymkeric substance in the described pressure-sensitive adhesive layer 32, the static that produces when it just can effectively be removed described barrier film 31 and removes.In addition, described first tack coat 34 and second tack coat 36 are used for described light shield layer 35 is bonded between described polarisation main body 33 and the described diaphragm 37.Particularly, described first tack coat 34 is bonded between described polarisation main body 33 and the described light shield layer 35, and described second tack coat 36 is bonded between described light shield layer 35 and the described diaphragm 37.
When described liquid crystal display module 20 uses polaroid shown in Figure 3, because described polaroid inside has a light shield layer 35 that makes by silk screen printing process, therefore, compared to prior art, described liquid crystal display module 20 need additionally not be provided with anti-dazzling screen and prevent to produce light leakage phenomena between liquid crystal panel 22 and module backlight 28.Thus, on the one hand, because the controllable thickness of the described light shield layer 35 that makes by silk screen printing process is built in micron dimension, and because it adopts original polaroid as holder, therefore adopt polaroid shown in Figure 3 can effectively reduce the thickness of described liquid crystal display module 20, help the slimming of described liquid crystal display module 20.On the other hand, described liquid crystal display module 20 inside do not need to increase extra anti-dazzling screen, thereby can simplify the assembling procedure of described liquid crystal display module 20.
In addition, as noted earlier, first polaroid 21 and second polaroid 23 in the described liquid crystal display module 20 all can adopt polaroid shown in Figure 3.But, should be understood that, in the specific embodiment of described liquid crystal display module 20, can only have one to adopt polaroid shown in Figure 3 in described first polaroid 21 and described second polaroid 23, and another adopt the common polaroid that does not have light shield layer 35.In specific embodiment, in order to guarantee shaded effect, preferably, described first polaroid 21 and described second polaroid 23 can all adopt polaroid shown in Figure 3.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
