Description

The glass substrate structure of LCD

Technical field

The utility model relates to a kind of glass substrate complex technique with high color contrast, relates in particular to a kind of glass substrate structure of LCD.

Technical background

As shown in Figure 1, 2, on glass substrate 10 1 surfaces of conventional liquid crystal, all dispose anti-reflecting layer 11,, reduce simultaneously because of the formed mirage phantom of this reflected light so that can reduce the light quantity that glass substrate 10 surfaces are reflected.

General anti-reflecting layer 11 is repeatedly connect alternately by silicon dioxide film 111, titanium dioxide film 112 to be formed, this anti-reflecting layer 11 mostly is that sputter titanium or silicon are reached in the oxygen atmosphere, when producing the compound anti-reflecting layer 11 of this kind, four sputter stations need be set individually, and all sputter stations need remain under the vacuum, can go out each silicon dioxide film 111, titanium dioxide film 112 of 2 layers at glass substrate 10 surface interaction sputters.

Therefore these glass substrate 10 composite structures have following problem at least has to be overcome:

One, its anti-reflecting layer 11 can't fully reduce the light penetration rate, so the lifting of color contrast be there is no any benefiting.

Two, it makes the equipment of silicon dioxide films 111, titanium dioxide film 112 with four sputter stations, and is quite expensive, can not reduce the number of plies of this silicon dioxide film 111, titanium dioxide film 112 again under primary demand, otherwise that mirage phantom just can be suitable is serious.

In view of this, the inventor grinds through constantly conceiving, creating with for many years professional experiences and gains in depth of comprehension, develops the utility model.

The utility model content

The purpose of this utility model is to provide a kind of glass substrate structure with LCD of high color contrast.

A kind of glass substrate structure of LCD comprises: a glass substrate has corresponding first surface and second surface; One metal decay film is disposed at described glass substrate first surface, and this metal decay film is non-oxide metal, and its THICKNESS CONTROL makes this metal decay film have enough transparencys or translucence between 2 nanometer to 20 nanometers; One anti-reflecting layer, it is disposed at metal decay film another side, makes metal decay film between glass substrate and anti-reflecting layer.Because of non-oxide metal decay film has preferable extinction physical property, make glass substrate group light penetration rate reduce, and then increase color contrast.

The glass substrate structure of described LCD, its anti-reflecting layer is made of the layer of silicon dioxide film.

Described anti-reflecting layer is made of titanium dioxide film that repeatedly connects and silicon dioxide film, makes titanium dioxide film between metal decay film and silicon dioxide film.

Described glass substrate second surface is coated with second metal decay film, and this second metal decay film is a non-oxide metal, and its thickness is 2 nanometer to 20 nanometers.Make this second metal decay film have enough transparencys or translucence.

Described second metal decay film another side is coated with second anti-reflecting layer.

Described second anti-reflecting layer is made of the layer of silicon dioxide film.

Described second anti-reflecting layer is made of titanium dioxide film that repeatedly connects and silicon dioxide film, and titanium dioxide film is between second metal decay film and silicon dioxide film.

Described glass substrate second surface is coated with second anti-reflecting layer, and this second anti-reflecting layer is repeatedly to connect titanium dioxide film, silicon dioxide film, titanium dioxide film, silicon dioxide film composition in regular turn at the glass substrate second surface.

After adopting such scheme, the utlity model has following advantage:

1. because of non-oxide metal decay film has preferable extinction physical property, the light penetration rate is reduced, and then increase color contrast greatly.

2. by described metal decay film is set, the compound number of plies of anti-reflecting layer is effectively reduced, under minimum requirements, only need the layer of silicon dioxide film so can reduce this anti-reflecting layer production line sputter station usage quantity and manufacturing cost for it.

3. the utility model metal decay film and anti-reflecting layer integral thickness and the number of plies far beyond traditional anti-reflecting layer still less can reduce the harmful effect of refractive index.
