Embodiment
As shown in Figure 3, the utility model comprises module 10 backlight, first transparency carrier 20, reflection horizon 30, first transparency conducting layer 40, liquid crystal layer 50, second transparency conducting layer 60 and second transparency carrier 70.
Moreover module 10 backlight provides directional light 12.Because colored filter 80 is arranged at the outside of first transparency carrier 20 or second transparency carrier 70, can forms along with the beholder position and manifest different colours and brightness, so can improve display effect of the present utility model through directional light 10.
Moreover first transparency conducting layer 40 and second transparency conducting layer 60 are tin indium oxide (ITO) or indium zinc oxide (IZO), and liquid crystal layer 50 is to adopt STN Super TN (STN), twisted nematic (TN) or bistable nematic (BiNem) structure.
The reflectivity in reflection horizon 30 is between 15% to 95%.
The manufacture method of the utility model colored filter 80 can be following method and makes:
(1) dye method (dyeing method): but the water soluble polymer of absorbing dye is imported the sensitization composition and makes the absorption layer material; This material is coated on the glass baseplate, and produced required little image with the exposure imaging processing procedure; The glass baseplate of coating absorption layer material contained to be dipped in the dye solution dye; Through manufacturing steps such as three coatings, exposure imaging, dyeing,, promptly can be made into colored filter at last respectively at catching R, G, B three looks in the zone of appointment.
(2) pigment dispersing method (pigment dispersion method): this method is present each widely used manufacture method of colored filter manufacturing plant, on the mode coated substrates of colored photoresist with rotary coating; Make little shadow color lump (color area) via exposure imaging.Colored photoresist is that color pigment is dispersed in wherein photoresist, and it has the characteristic of irradiation reaction and thermmohardening.R, G, B three color coloured light cause resist must make colored filter through the coating exposure of three roads, developing manufacture process.
(3) electrochemical plating (electrodeposition method): earlier transparency electrode (ito glass) is produced little image (pattern); Again this transparency electrode is put into electroplating bath, contain the resin and the electrolyte of dispersed color, dissolving in the electro dipping solution; This composition of electroplating applying soln is plated on the transparency carrier handles through overbaking (baking) again.The triplicate processing procedure plates R, G respectively, three layers of color lump of B promptly can be made into colored filter.
(4) print process (printing method): with pigment dispersing in thermmohardening type resin; Go out coloured image with mode of printing in that base material is above-listed; Thermmohardening is handled again.Triplicate can be made into the colored filter of tool R, G, B image three-colo(u)r.
As Fig. 5, shown in Figure 6, the top that is arranged at second transparency carrier 70 with the utility model colored filter 80 is an example, colored filter 80 can be by bat printing, ink jet printing, lithography, letterpress, rotary coating or screen painting, R, G, B color lump 82 are imprinted on the surface of the substrate 84 or second transparency carrier 70, wherein the substrate 84 and second transparency carrier 70 all can be plastic cement or glass material, and the color lump 82 of colored filter 80 placements this moment is arranged in arbitrary surface, upper and lower surface of the substrate 84 and second transparency carrier 70.
As Fig. 7, shown in Figure 8, the below that is arranged at first transparency carrier 20 with the utility model colored filter 80 is an example.
Because color filter film 80 is arranged at the below of first transparency carrier 20 or the top of second transparency carrier 70, be that color filter film 80 is arranged at the transparency carrier outside, as shown in Figure 7, variation along with the visual angle, color is become with brightness significantly to be changed, so as shown in Figure 8, the directional light that the utility model utilizes module backlight to provide just can reduce the problem of parallax.
