Abstract
The coloured glass filter films with strong adhesive power are prepared on the surfaces of colourless glass and conductive glass by using tetraethyl orthosilicate as matrix material and adopting gel method. This coloured filter film is mainly used for implementing polychromatic liquid crystal display. Said film can resist UV radiation and high-temp, and its chemical properties are stable.
Description
The invention belongs to a kind of colour light filter film that is used for the liquid-crystal display colorization.
Each manufacturer all uses colour light filter film as liquid-crystal display color scheme at present.The preparation method of colour light filter film has staining, electrodip process, print process and painted polymer method.Coloured and the color filter film that these methods finally are prepared into all is to be made of organic substance, has following shortcoming:
1. resistance toheat is poor, and preparation technology requires harshness to liquid-crystal display;
2. the uvioresistant irradiation behaviour is poor, and process for manufacturing liquid crystal display and environment for use are restricted.
With tetraethoxy Si (OEt) 4 is raw material, by gel method prepare silicon oxide film [refreshing paddy is wide by one. he: ceramic industry association will, 86 (11) 552-9 (1978); Yamane, M.et, al, Master, Sci, 14 (3) 607-11 (1979); Wang Yukuan etc., glass and enamel, 11 (2) 13-25 (1981)], can avoid the shortcoming of organic substance filter coating, but this filter coating is colourless.
The purpose of this invention is to provide a kind of is the colour light filter film of substrate material with the silicon oxide.
To achieve these goals, the technical solution used in the present invention is as follows: one, chemical feedstocks:
1) tetraethoxy Si (OEt) 4
2) dehydrated alcohol
3) purify waste water
4) hydrochloric acid
5) selenium, cadmium, sulphur
6) zinc oxide two, preparation of raw material
Tetraethoxy: hydrochloric acid=1: 0.8～1.2 (volume ratio)
[tetraethoxy+hydrochloric acid]: ethanol=0.7～1.5: 1 (volume ratio)
Tetraethoxy, hydrochloric acid and ethanol are mixed in proportion, tinting material Se, Cd and S, stablizer Zn mixes with compound solution, and its quantity and ratio are determined by design requirements (seeing through wavelength and transmitance).
The solution of above-mentioned preparation after fully stirring under 20～90 ℃ of temperature, is placed 15～85 ℃, and humidity is that through a few hours posthydrolysis bunching, soltion viscosity begins to increase in 50～80% the environment.Select proper viscosity, need painted position coated or print this solution on flint glass or ITO surface,, make it gelling under 45～85% humidity 35～95 ℃ of temperature.The xerogel film is heated to 100～150 ℃, remove moisture content and the most of organic substance in the xerogel film and make it fine and close.In 210～420 ℃ weakly reducing atmosphere, this glued membrane is carried out vitrifying and the processing of colour developing metallization processes.
Colour light filter film of the present invention has the following advantages:
1. UV resistant radiation;
2. can prolong colour light filter film and liquid crystal display device work-ing life;
3. high temperature resistant.
Below in conjunction with drawings and Examples the present invention is described in detail.
Fig. 1 is a synoptic diagram of the present invention.
1-sheet glass among the figure; 2-colour light filter film; 3-optical waveguide layer.
Embodiment one,
One, proportioning raw materials:

4) stablizer ZnO (ZnO: Cd=1.4: 1)
Two, preparation process
Under the room temperature solution fully being stirred, is 60 ℃ in temperature, and humidity is to place 4 hours under 70% environment, and being coated on area then is 1 (contacting with conductive layer 3) on the colourless conductive glass of 100 * 100mm, through 130 ℃ of thermal treatments in 2 hours, forms xerogel thin film.Through promptly forming the selenium cadmium orange look glass light filter film 2 of strong adhesion after 310 ℃ the thermal treatment on the surface at flint glass, film thickness is 6 μ m under weakly reducing atmosphere, and the printing opacity wavelength is 570nm, and transmitance is 90%.
Embodiment two,
One, proportioning raw materials:
1) tetraethoxy: hydrochloric acid=1: 0.8 (volume ratio)
2) [tetraethoxy+hydrochloric acid]: ethanol=1.12: 1 (volume ratio)
3) tinting material Se: Cd: S=1: 9: 1
4) stablizer ZnO (ZnO: Cd=10: 1)
Two, preparation process
With embodiment one.Form the selenium cadmium red look glass light filter film of strong adhesion on the surface of flint glass, thickness is 3.6 μ m, and the printing opacity wavelength is 630nm, and transmitance is 92%.
