STN display pattern.And STN display pattern can be divided into：The Y-STN of yellow background black display picture, blue background white are aobvious
Show the B-STN of picture, the FSTN of white background black display picture, the FSTN of black background white displays picture, gray background
The G-STN of purple display picture.
With the continuous development of human scienceses' technology, the needs of people's real life, various new display modes are by successively
Develop.Colour picture under mirrored background shows to be also one of them.The liquid crystal display of this invention make use of mirror type
The optical characteristics of polaroid（Select reflexive）, and mate colour reflective diaphragm it is achieved that the colour under mirrored background shows（Produce
Product are mirror when being not added with voltage, show the picture of colour during making alive on minute surface）.There is good contrast（Carry on the back with white
Under scape, black picture TN, FSTN reflection LCD is close）, bright-colored uniform feature, it is possible to use existing STN sets
Standby and technique productions, make simple, low price.
Content of the invention
It is an object of the invention to provide a kind of liquid crystal display of mirrored background colour display picture and its crucial manufacture
Technique, using the feature of existing LCD production technology and mirror type polaroid, can produce mirrored background colour picture liquid crystal
Display.There is making simple, good contrast, visible angle width, background and the uniform advantage of Show Color.
For achieving the above object, the present invention employs the following technical solutions realization：
A kind of liquid crystal display of mirrored background colour display picture, includes upper polaroid, ito glass, liquid crystal layer, lower inclined
Mating plate, is separated by liquid crystal layer in the middle of two panels ito glass, and it is outer parallel with upper strata ito glass that upper polaroid is arranged on upper strata ito glass
Connect, down polaroid is arranged on the outer connection parallel with lower floor ito glass of lower floor's ito glass it is characterised in that described upper polarisation
Piece adopts TN common transmission piece or STN composite membrane, and down polaroid adopts mirror type polaroid, in the outermost layer patch of down polaroid
With colour reflective diaphragm.
The key manufacturing technology of the liquid crystal display of described mirrored background colour display picture, using following steps：
1）Upper polaroid adopt TN common transmission piece or STN composite membrane, STN composite membrane use 580nm, 45 ° compensation
Composite membrane；
2）Down polaroid adopts mirror type polaroid, is pasted with colour reflective diaphragm in the outermost layer of down polaroid；Realize
Under mirrored background, colour picture shows；
3）During no-voltage, display assumes mirror effect；During making alive, assume colour reflective diaphragm colored picture.
Compared with prior art, the invention has the beneficial effects as follows：
The display effect of colour picture under achievable mirrored background, can be fabricated to TN pattern and STN mode, and STN mode regards
Angle is wider, and display content is more, and liquid crystal display has that making is simple, low price, good contrast, visible angle width, background
The uniform feature with Show Color.
Brief description
Fig. 1 is the structure chart of the present invention.
Fig. 2 is the schematic diagram of invention mirror reflection.
1- upper polaroid 2-ITO glass 3- frame 4- liquid crystal layer 5- down polaroid 6- colour reflective diaphragm
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is further illustrated：
As shown in figure 1, the liquid crystal display of mirrored background colour display picture, by upper polaroid 1, ito glass 2, frame
3rd, liquid crystal layer 4, down polaroid 5 and colored diaphragm 6 form, and are separated by liquid crystal layer 4, upper polaroid 1 sets in the middle of two panels ito glass 2
Put outer parallel with upper strata ito glass 2 connected in upper strata ito glass 2, down polaroid is arranged on outside lower floor's ito glass 2 and lower floor
Ito glass 2 is parallel to be connected, and bottom one layer parallel connected with down polaroid 5 to be colour reflective diaphragm 6.Upper polaroid 1 can use
TN common transmission piece or STN use 580nm, the composite membrane of 45 ° of compensation.
Principle using TN common transmission piece or STN composite membrane LCD liquid crystal display makes liquid crystal cell, drives in no-voltage
When dynamic, in the upper and lower base plate of ito glass 2, levels liquid crystal molecule forms 90 degree or 240 degree distortions to liquid crystal molecules parallel, inclined with upper
Mating plate 1 and down polaroid 5 compensate, and down polaroid 5 is with DBEF-A mirror type polaroid, and attaches colored diaphragm 6（As red,
Blue, green etc. it is also possible to by display figure multiple color combination）, to realize the colored display of mirrored background.Drive when there being voltage
When liquid crystal 4 molecule perpendicular to upper and lower base plate, the color of product is the color of colored front diaphragm（If red diaphragm is red pattern,
Blue diaphragm is blue color patterns）；No-voltage is mirrored effect when driving.
Displaying principle is as follows：
1. during no-voltage：P light is absorbed, and S light is changed into P light through liquid crystal, meets DBEF-A direct reflection, is then passed through liquid crystal and becomes
Pass through upper polaroid for S light, assume mirror effect（Mirror）.
2. during making alive：P light is absorbed, and S light passes through upper polaroid, liquid crystal, down polaroid, meets colour reflective diaphragm anti-
Penetrate, again pass through down polaroid, liquid crystal, upper polaroid, assume colored diaphragm colored picture.
Mirrored background colour picture liquid crystal display employs following critical process：
1. TN the or FSTN liquid crystal display color making must be white.
2. down polaroid adopts mirror type polaroid（DBEF-A）.
3. using colour reflective diaphragm, the reflectance of diaphragm is sufficiently high.
4. the ito glass using is as far as possible thin.
Mirrored background colour picture liquid crystal display mainly has following characteristic：
1. colour picture liquid crystal display background is bright reflective minute surface, the pattern of the colored diaphragm color of display, permissible
Realize mirror and the dual-use function of colored display.
2. colour picture liquid crystal display, can make TN pattern and STN mode, and TN pattern contrast is higher, and price is more
Low；STN mode visual angle is wider, and display content is more.
