Preferably, described transparency electrode is ITO indium tin oxide or IZO indium-zinc oxide.
Preferably, described black matrix" is ferrous metal.
Preferably, described ferrous metal is Cr chromium or CrO chromium oxide.
A kind of method for making of wide-angle liquid crystal display of white and black displays, the wide-angle liquid crystal display of white and black displays comprises: lower sheet glass, upper sheet glass and the conducting metal that is used to connect upper and lower sheet glass, described upper sheet glass comprises glass substrate, upper surface at described glass substrate arranges black matrix", at the upper surface of described black matrix", transparency electrode is set.
Preferably, described upper surface at described glass substrate arranges black matrix", and the process that transparency electrode is set at the upper surface of described black matrix" comprises:
Upper surface at described black matrix" arranges described transparent metal electrode, then the lower surface that described upper surface is arranged the black matrix" of described transparent metal electrode is connected with the upper surface of described glass substrate, makes described black matrix" be arranged at described glass substrate upper surface.
The present invention is by changing the structure of product, mainly be the change of sheet glass project organization, there is bilateral structure to change single-sided structure into upper sheet glass, simplified technological process, effectively controlled simultaneously the scuffing problem of bilateral structure in production flow process, flatness and homogeneity are better, help to reduce the defectives such as display dot (MURA) because the liquid crystal cell lack of homogeneity causes, and improve yields.
Description of drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain with reference to the accompanying drawings other accompanying drawing.
Fig. 1 is the wide-angle liquid crystal display structural representation of traditional white and black displays;
Fig. 2 is the wide-angle liquid crystal display structural representation of white and black displays of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The present embodiment provides a kind of wide-angle liquid crystal display of white and black displays, its structure as shown in Figure 2, comprise sheet glass 21, lower sheet glass 22 and be connected sheet glass and the conducting metal 23 of lower sheet glass, wherein, upper sheet glass 21 comprises: glass substrate 211, black matrix" 212 and transparency electrode 213.In the present embodiment, tradition is arranged at the described black matrix" of upper sheet glass lower surface, is arranged at the upper surface of sheet glass, thereby make the lower surface of sheet glass need not to arrange black matrix", also with regard to the uneven problem of the lower surface of having avoided upper sheet glass, make lower surface need not to arrange any layer.
Black matrix" described in the wide-angle liquid crystal display structure of white and black displays and transparency electrode are in necessary two-layer the present embodiment, described black matrix" to be arranged at the upper surface of upper sheet glass, and do not affect display effect, the lower surface of going up sheet glass need not to arrange described planarization layer, so the present invention is simple than prior art.
In addition, in the present embodiment, described transparency electrode can be used ITO (Indium Tin Oxide indium tin oxide), IZO (Indium Zn Oxide indium-zinc oxide), described black matrix" uses the ferrous metal setting, ferrous metal can be used Cr/CrO (chromium/chromium oxide), but is not limited to these, can replace with other metal or metal oxide.
The present embodiment also provides a kind of method for making of wide viewing angle display of white and black displays, at first, the present embodiment is to use ferrous metal the upper surface setting of the glass substrate of upper sheet glass, chromium for example, the black matrix" that the materials such as chromium oxide are made, then, upper surface at described black matrix" arranges use, ITO (Indium Tin Oxide indium tin oxide) for example, the transparent metal electrode that the materials such as IZO (Indium Zn Oxide indium-zinc oxide) are made, its structure of the demonstration of made is with reference to Fig. 2 as stated above.
In the method for making of the wide viewing angle display of a kind of white and black displays that the present embodiment provides, described upper surface at described glass substrate arranges black matrix", the upper surface of described black matrix" arrange transparency electrode process can for: the upper surface at described black matrix" arranges described transparent metal electrode, then the lower surface that described upper surface is arranged the black matrix" of described transparent metal electrode is connected with the upper surface of described glass substrate, makes described black matrix" be arranged at described glass substrate upper surface.Namely, at first, with ferrous metal chromium for example, the black matrix" upper surface that the materials such as chromium oxide are made arranges with for example ITO (Indium Tin Oxide indium tin oxide), the transparent metal electrode that the materials such as IZO (Indium Zn Oxide indium-zinc oxide) are made, then, these two parts are arranged on glass substrate.Perhaps; adopt and at first black matrix" is arranged on the upper surface of glass substrate, then at the upper surface of black matrix", the mode of transparency electrode is set; the present embodiment does not limit its concrete mode, as long as can realize that the mode of structure as shown in Figure 2 is all the scope of the present embodiment protection.
Because the lower surface of the described glass substrate of upper sheet glass need not to arrange black-matrix layer, thus also just avoided the uneven situation of lower surface to occur, so lower surface need not to be provided with planarization layer again.
In the method to set up of the wide viewing angle display of the described a kind of white and black displays of the present embodiment, remove the method to set up of above-mentioned black matrix" etc., remaining is conducting metal and lower sheet glass for example, and the method to set up of the part between upper sheet glass and lower sheet glass etc., all identical with method to set up of the prior art.
