Abstract

The utility model relates to a high reliability LCD, LCD by polarizing on, liquid crystal cell and down the polaroid forms, wherein the liquid crystal cell by go up to the last glass substrate that sets gradually down certainly, go up the ITO layer, go up PI orientation layer, the liquid crystal layer, oriented layer of PI, lower ITO layer and lower glass substrate form down, the surface integral of upper and lower polaroid do not is less than upper and lower glass substrate's area, polarizing on and lower polaroid are peripheral to be sealed through UV glue, and the scope that sets up of UV glue more than vertical orientation, down the polaroid lateral surface be the boundary, glass substrate or glass substrate marginal boundary that is around down more than the horizontal direction, the polaroid protection film is established to upper and lower polaroid lateral surface. The utility model discloses a polaroid easy layering and inefficacy problem that appears in the humid tropical environment is thoroughly solved to the structure that UV glue sealed, improves the tolerance of LCD to the humid tropical environment, its simple structure, it is convenient to make, utilizes the existing equipment to produce.

Description

A kind of high reliability liquid crystal display

Technical field

The utility model relates to LCD Technology field, particularly relates to a kind of high reliability liquid crystal display higher to hot and humid environment durability requirements.

Background technology

In recent years, liquid crystal display has been widely used in the numerous areas of national economy and national defense safety, along with the continuous expansion of products application scope, also more and more higher to the reliability requirement of product, but the performance of LCD product withstand high temperatures high humidity can't meet the demands at present, say from product structure, the bottleneck of this problem causes because polaroid serviceability in hot and humid environment is tested is unstable.

Summary of the invention

The utility model provides a kind of high reliability liquid crystal display, adopts the structure that UV glue is closed, and the layering that thorough solution polaroid easily occurs in hot and humid environment and Problem of Failure, improve liquid crystal display to the tolerance of hot and humid environment; Its structure is simple, easily manufactured, utilizes existing equipment to produce.

In order to achieve the above object, the utility model realizes by the following technical solutions:

A kind of high reliability liquid crystal display, comprise the liquid crystal display be made up of upper polaroid, liquid crystal cell and lower polaroid, wherein liquid crystal cell is made up of the top glass substrate set gradually from top to bottom, upper ITO layer, upper PI oriented layer, liquid crystal layer, lower PI oriented layer, lower ITO layer and lower glass substrate; The area of upper and lower polaroid is less than the area of upper and lower glass substrate respectively; Described upper polaroid and lower polaroid periphery are closed by UV glue, and the scope that arranges of UV glue at vertical direction with upper and lower polaroid lateral surface for boundary, horizontal direction with the edge of top glass substrate or lower glass substrate for boundary; Upper and lower polaroid lateral surface establishes polarizing plate protective film.

Compared with prior art, the beneficial effects of the utility model are:

1) structure adopting UV glue to close, the layering that thorough solution polaroid easily occurs in hot and humid environment and Problem of Failure, improve liquid crystal display to the tolerance of hot and humid environment;

2) structure is simple, easily manufactured, utilizes existing equipment to produce, increases production cost hardly.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:

Seeing Fig. 1, is structural representation of the present utility model.A kind of high reliability liquid crystal display of the utility model, comprise the liquid crystal display be made up of upper polaroid 1, liquid crystal cell 2 and lower polaroid 3, wherein liquid crystal cell 2 is made up of the top glass substrate 21 set gradually from top to bottom, upper ITO layer, upper PI oriented layer 22, liquid crystal layer 23, lower PI oriented layer 24, lower ITO layer and lower glass substrate 25; The area of upper and lower polaroid 1,3 is less than the area of upper and lower glass substrate 21,25 respectively; Described upper polaroid 1 is closed by UV glue 4 with lower polaroid 3 periphery, and the scope that arranges of UV glue 4 at vertical direction with upper and lower polaroid 1,3 lateral surface for boundary, horizontal direction with the edge of top glass substrate 21 or lower glass substrate 25 for boundary; Upper and lower polaroid 1,3 lateral surface establishes polarizing plate protective film.(as shown in Figure 2)

The manufacturing process of a kind of high reliability of the utility model liquid crystal display is as follows:

1)--------------polaroid is pasted in cleaning--photoelectricity inspection--to silk-screen to etching, making LCD product in sealing to close box solidification-liquid crystal filling in friction in exposure in LCD production procedure routinely: ito substrate;

2) complete after LCD product, closed by coating UV glue 4 in upper polaroid 1 periphery of simple grain LCD; Select the UV glue with polaroid 1,3 with suitable affinity, during coating UV glue 4, even lower glue around upper polaroid 1, UV glue 4 is trickled naturally in top glass substrate 21, and ensureing that the height of UV glue 4 is no more than the upper side of upper polaroid 1 by controlling lower glue amount, width is no more than the outer ledge of top glass substrate 21; After the UV glue 4 applied tentatively solidifies, LCD product is cured through UV stove;

3) the simple grain LCD top and bottom upset after single spreading solidification, by and step 2) periphery of lower polaroid 3 closes by applying UV glue 4, after the UV glue 4 applied tentatively solidifies, then is cured through UV stove by LCD product by same procedure;

4) polarizing plate protective film is pasted respectively at upper and lower polaroid 1,3 lateral surface.

In the utility model, selected UV glue 4 needs and polaroid 1,3 has suitable affinity, simultaneously by controlling lower glue amount, makes UV glue 4 can not flow to polaroid 1, between 3 and polarizing plate protective film.

Liquid crystal layer 23 in the utility model is using wadding 26 as skeleton, and around filling liquid crystal 27 is formed, and liquid crystal layer 23 is enclosed between upper PI oriented layer 22 and lower PI oriented layer 24 by frame adhesive 28.

The above; be only the utility model preferably embodiment; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection domain of the present utility model.
