Abstract
The utility model relates to an FSTN liquid crystal display with a blue frame. The FSTN liquid crystal display with the blue frame comprises an upper piece of ITO glass, a lower piece of ITO glass, an upper layer polaroid, a lower layer polaroid and liquid crystals. The FSTN liquid crystal display with the blue frame is characterized in that the upper layer polaroid is formed by a blue polaroid and compensation film in a composite mode, the lower layer polaroid is a permeable type polaroid or a reflecting type polaroid or a semi-permeable type polaroid, and the display effect of the blue frame on a white background is achieved. A twist angle of each liquid crystal is 240 degrees, and the optical path difference of each liquid crystal is 840nm. The upper layer polaroid is formed by the compensation film with the optical path difference of 570nm and the blue polaroid with an included angle of 45 degrees in the composite mode. The FSTN liquid crystal display with the blue frame has the advantages that the special blue frame which is arranged on the FSTN liquid crystal display with the blue frame is displayed on the white background, the visual angle is wide, and a contrast ratio is good.
Description
Technical field
The utility model relates to a kind of lcd technology of blue display frame, shows the liquid crystal display manufacturing technology at the blue picture of white background especially.
Background technology
LCD is a kind of flat-panel screens that is widely used, and has features such as low in energy consumption, slim body, in light weight and driving voltage be low.Conventional liquid crystal display mode has the TN display mode that is fit to low line number driving and is fit to the STN display mode that high line number drives.And the STN display mode can be divided into: FSTN, the G-STN of gray background purple display frame of the B-STN of the Y-STN of yellow background black display picture, the display frame of blue background white, the FSTN of white background black display picture, the display frame of black background white.
Along with the continuous development of human sciences's technology, people require to get more and more, and the display requirement of white background colour picture has also been carried.Blue picture shows it also is one of them.The LCD display mode of the common white figure viewed from behind has only the black picture, and use B-STN all relatively poor with blue product contrast, color, the visual angle that shows of white background that anti-explicit program shows, or use TFT fabrication techniques coloured prod, and price is very expensive, and appointed condition requires also very high.And the LCD of this invention has good contrast (identical with white background black picture FSTN LCD), the wide uniform characteristics of visible angle, color, can use existing STN equipment and explained hereafter, makes simply low price.
Summary of the invention
The purpose of this utility model is to provide a kind of blue picture FSTN LCD, can realize the display effect of the blue picture of white background, and LCD has makes simply, and good contrast, visible angle are wide, background and the uniform characteristics of Show Color.
For achieving the above object, blue picture FSTN LCD has adopted following core technology:
Blue picture FSTN LCD, comprise an ito glass, following sheet ito glass, upper strata polaroid, lower floor's polaroid, liquid crystal, it is characterized in that, described upper strata polaroid adopts blue polaroid and compensate film to be composited, described lower floor polaroid is through mode, reflective or semi-permeable polaroid, realizes the blue picture display effect of white background.
Described liquid crystal twist angle 240 degree, optical path difference 840nm.
Described upper strata polaroid uses the compensate film of 570nm and blue polaroid angle 45 degree to be composited.
Compared with prior art, the beneficial effects of the utility model are: display has special blue picture and shows that on white background visible angle is than broad, and contrast is better.Its structure is: two-layer ito glass substrate, and stn liquid crystal, the upper strata is the blue composite membrane polaroid of band compensation, lower floor can be through mode, semi-permeable or reflecting polarized wafer.
Description of drawings
Fig. 1 is the product structure figure of blue picture FSTN LCD.
Among the figure: sheet ito glass 7-lower floor polaroid under the blue polaroid 2-of the 1-compensate film 3-last slice ito glass 4-frame 5-liquid crystal 6-
Embodiment
Below in conjunction with accompanying drawing concrete technology contents of the present utility model is described in further detail.
See Fig. 1, blue picture FSTN LCD comprises the upper strata polaroid that is composited by blue polaroid 1 and compensate film 2, last slice ito glass 3, sheet ito glass 6, liquid crystal 5, frame 4 down.Adopt the STN technology, liquid crystal twist angle 240 degree, optical path difference 840nm.Lower floor's polaroid 7 can use conventional through mode, reflective, semi-permeable polaroid, realize band white backlight source through mode display mode, band white backlight source scalable backlight switch the semi-permeable display mode and not with the reflective display mode of backlight.
Blue picture FSTN LCD has adopted following critical process:
1. use STN manufacturing technology and production equipment.
2. use the compound of blue polaroid 1 and compensate film 2, be used for the last polaroid of product, compensate with product colour.Polaroid complex method: use the compensate film of 570nm and blue polaroid angle 45 degree compound.
The optical path difference of 2. regulating liquid crystal is 840nm, with the polaroid complementary colors, realizes the white background color.
As shown in Figure 1, blue picture FSTN LCD utilizes the principle of STN LCD to make liquid crystal cell, and liquid crystal molecule is parallel to the upper and lower base plate of glass when no-voltage drives, and the levels liquid crystal molecule forms 240 degree distortions, with the compensation of levels polaroid, product is white (slight blue partially).Liquid crystal molecule is perpendicular to upper and lower base plate when driven, and product is the color (blueness) of surperficial polaroid.
Specific embodiment: blue picture FSTN LCD mainly contains following characteristic:
1. blue picture FSTN LCD form and aspect see the following form:
| ? | Backlight in vain | Do not show form and aspect | Show form and aspect |
| Brightness Lv | 357.4 | 108.0 | 36.2 |
| Form and aspect x | 0.2565 | 0.2501 | 0.1865 |
| Form and aspect y | 0.2453 | 0.2427 | 0.1374 |
[0022] By data in the table as can be known, blue picture FSTN LCD background color is white phase, is shown as blueness.
2. blue picture FSTN LCD, the upper strata polaroid is blue polaroid, and polarity is lower, and not obvious with the compound back of compensate film directivity, each visual angle contrast difference of product is also less, and each visual angle shows more even, the visual angle broad.
Claims (3)
1. blue picture FSTN LCD, comprise an ito glass, following sheet ito glass, upper strata polaroid, lower floor's polaroid, liquid crystal, it is characterized in that, described upper strata polaroid adopts blue polaroid and compensate film to be composited, described lower floor polaroid is through mode, reflective or semi-permeable polaroid, realizes the blue picture display effect of white background.
2. blue picture FSTN LCD according to claim 1 is characterized in that, described liquid crystal twist angle 240 degree, optical path difference 840nm.
