Compared with the prior art, the liquid crystal display has the beneficial effects that the display effect of the colored picture under the mirror surface background can be realized; the liquid crystal display has the characteristics of being simple in manufacturing, cheap in price, good in contrast ratio, wide in visual angle and uniform in background and display colors.
Description
Technical field
The present invention relates to the lcd technology that under a kind of minute surface figure viewed from behind, colour picture shows, the special liquid crystal display manufacturing technology for various single color picture displies under the minute surface figure viewed from behind.
Background technology
Liquid crystal display is a kind of flat-panel screens be widely used, and has the features such as low in energy consumption, slim body, lightweight and driving voltage be low.Conventional liquid crystal display mode has the TN display mode that is applicable to low way driving and is applicable to the STN display mode that high way drives.And the STN display mode can be divided into: the FSTN of the B-STN of the Y-STN of yellow background black display picture, blue background white displays picture, the FSTN of white background black display picture, black background white displays picture, the G-STN of gray background purple display frame.
Along with the development of human sciences's technology, the needs of people's real life, various new display modes are developed successively.It is also one of them that colour picture under the minute surface background shows.The liquid crystal display of this invention has been utilized the optical characteristics (selection reflectivity) of mirror type polaroid, and coupling colour reflective diaphragm, realized that colour under the minute surface background shows (product is mirror when making alive not, during making alive on minute surface the picture of display color).There are good contrast (close with black picture TN under white background, FSTN reflection LCD), bright-colored uniform characteristics, can use existing STN equipment and process production, make simple, low price.
Summary of the invention
The object of the present invention is to provide liquid crystal display and the key manufacturing technology thereof of the display frame of a kind of minute surface background color, utilize the characteristics of existing LCD production technology and mirror type polaroid, can produce minute surface background color picture liquid crystal display.Have and make simply, good contrast, visible angle are wide, background and the uniform advantage of Show Color.
For achieving the above object, the present invention realizes by the following technical solutions:
The liquid crystal display of a kind of minute surface background color display frame, comprise polaroid, ito glass, liquid crystal layer, lower polaroid, in the middle of two ito glasses, by liquid crystal layer, separated, upper polaroid be arranged on the upper strata ito glass outer with the parallel connection of upper strata ito glass, lower polaroid be arranged on lower floor's ito glass outer with the parallel connection of lower floor's ito glass, it is characterized in that, described upper polaroid adopts the common transmission sheet of TN or STN composite membrane, lower polaroid adopts the mirror type polaroid, at the outermost layer of lower polaroid, is pasted with the colour reflective diaphragm.
The key manufacturing technology of the liquid crystal display of described minute surface background color display frame adopts following steps:
1) upper polaroid adopts the common transmission sheet of TN or STN composite membrane, and the STN composite membrane is used the composite membrane of 580nm, 45o compensation;
2) lower polaroid adopts the mirror type polaroid, at the outermost layer of lower polaroid, is pasted with the colour reflective diaphragm; Realize that under the minute surface background, colour picture shows;
3), during no-voltage, display presents mirror effect; During making alive, present colour reflective diaphragm color picture.
Compared with prior art, the invention has the beneficial effects as follows:
Can realize the display effect of colour picture under the minute surface background, can be made into TN pattern and STN pattern, STN pattern visual angle is wider, and displaying contents is more, liquid crystal display has makes simple, low price, and good contrast, visible angle are wide, background and the uniform characteristics of Show Color.
The accompanying drawing explanation
Fig. 1 is structural drawing of the present invention.
Fig. 2 is the schematic diagram of mirror-reflection of the present invention.
Polaroid 6-colour reflective diaphragm under the upper polaroid 2-ITO of 1-glass 3-frame 4-liquid crystal layer 5-
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
As shown in Figure 1, the liquid crystal display of minute surface background color display frame, be comprised of upper polaroid 1, ito glass 2, frame 3, liquid crystal layer 4, lower polaroid 5 and colored diaphragm 6, in the middle of two ito glasses 2, by liquid crystal layer 4, separated,
Utilize the principle of the common transmission sheet of TN or STN composite membrane LCD liquid crystal display to make liquid crystal cell, when no-voltage drives, liquid crystal molecule is parallel to the upper and lower base plate of ito glass 2, the levels liquid crystal molecule forms 90 degree or 240 degree distortions, with upper polaroid 1 and 5 compensation of lower polaroid, lower polaroid 5 is with DBEF-A mirror type polaroid, and attach colored diaphragm 6(as red, blue, green etc., and also can be by the combination of display graphics multiple color), to realize the minute surface background color, show.When having voltage to drive, liquid crystal 4 molecules are perpendicular to upper and lower base plate, the color that the color of product is colored front diaphragm (as red diaphragm is red pattern, blue diaphragm is blue pattern); No-voltage is mirror effect while driving.
Displaying principle is as follows:
1. during no-voltage: P light is absorbed, and S light becomes P light through liquid crystal, meets the DBEF-A mirror-reflection, then becomes S light through upper polaroid through liquid crystal, presents mirror effect (mirror).
2. during making alive: P light is absorbed, and S light, through upper polaroid, liquid crystal, lower polaroid, is met the reflection of colour reflective diaphragm, again, through lower polaroid, liquid crystal, upper polaroid, presents colored diaphragm color picture.
Minute surface background color picture liquid crystal display has adopted following critical process:
1. the TN made or FSTN liquid crystal display color must be white.
2. descend polaroid to adopt mirror type polaroid (DBEF-A).
3. use the colour reflective diaphragm, it is enough high that the reflectivity of diaphragm is wanted.
4. the ito glass used is as far as possible thin.
Minute surface background color picture liquid crystal display mainly contains following characteristic:
1. colour picture liquid crystal display background is bright reflective minute surface, and the pattern of display color diaphragm color can be realized mirror and the colored dual-use function shown.
2. the colour picture liquid crystal display, can make TN pattern and STN pattern, and TN pattern contrast is higher, and price is lower; STN pattern visual angle is wider, and displaying contents is more.
