Abstract
The utility model relates to a super twisted nematic (STN) liquid crystal display with green pictures. The STN liquid crystal display comprises an upper indium tin oxide (ITO) glass sheet, a lower ITO glass sheet, an upper-layer polaroid, a lower-layer polaroid and liquid crystals. The STN liquid crystal display is characterized in that a yellow printing oil silkscreen layer is coated on the upper ITO glass sheet, and then a blue polaroid is pasted on the yellow printing oil silkscreen layer to form the upper-layer polaroid. The lower-layer polaroid can be a transmissive type polaroid, or a reflective-type polaroid, or a semi-transmissive polaroid. Display effects with a light yellow background and the green pictures can be achieved. The twist angle of the liquid crystals is 240 degrees and the optical path difference of the liquid crystals is 830nm. Compared with the prior art, the STN liquid crystal display has the special display effects with the light yellow background and the green pictures, and is wide in visual angle and good in contrast ratio.
Description
Technical field
The utility model relates to the lcd technology of green display frame under a kind of light background, shows the liquid crystal display manufacturing technology at the green picture of faint yellow 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 requirement that colour picture shows has also been carried.Green picture shows it also is one of them.Usually the display frame color during LCD light color background has only black and purple, and green picture shows when having only the TFT of use fabrication techniques coloured prod just to be had, and price is very expensive, and appointed condition requires also very high.And the LCD of this invention can be utilized the color superposition principle by simple STN technology of preparing, can realize that the green picture of light background (faint yellow) shows.This product has good contrast, the wide low characteristics of visible angle, cost, 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 green picture stn liquid crystal display, realizes the display effect of the special green picture of light background, and LCD has makes simply good contrast, the wide characteristics of visible angle.
For achieving the above object, green picture stn liquid crystal display has adopted following core technology:
Green picture stn liquid crystal display, comprise an ito glass, following sheet ito glass, upper strata polaroid, lower floor's polaroid, liquid crystal, it is characterized in that, on last ito glass, apply Yellow ink silk-screen layer, on Yellow ink silk-screen layer, stick blue polaroid again and constitute the upper strata polaroid, lower floor's polaroid is through mode, reflective or semi-permeable polaroid, realizes the green picture display effect of faint yellow background.
Described liquid crystal twist angle 240 degree, optical path difference 830nm.
Compared with prior art, the beneficial effects of the utility model are: display has the green picture display effect of special faint yellow background, and visible angle is than broad, and contrast is better.
Description of drawings
Fig. 1 is the product structure figure of green picture stn liquid crystal display.
Among the figure: sheet ito glass 7-lower floor polaroid under the blue polaroid 2-of the 1-Yellow ink silk-screen layer 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.
Green picture stn liquid crystal display, comprise an ito glass 3, following sheet ito glass 6, upper strata polaroid, lower floor's polaroid 7, liquid crystal 5, described upper strata polaroid uses blue polaroid 1, on last ito glass 3, apply Yellow ink silk-screen layer 2, described lower floor polaroid 7 is through mode, reflective or semi-permeable polaroid, realizes the green picture display effect of faint yellow background.Described display adopts the STN technology, liquid crystal twist angle 240 degree, optical path difference 830nm.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.
Following critical process has been adopted in the development of green picture stn liquid crystal display:
1. use STN manufacturing technology and production equipment.
2. go up and apply Yellow ink silk-screen layer on the ito glass, and use blue polaroid, yellow and blueness synthesizes green, can realize green display frame during demonstration.
The optical path difference of 3. regulating liquid crystal is 830nm, with the polaroid complementary colors, realizes the faint yellow background color of ink silk screen printing layer.
The structure of green picture stn liquid crystal display is with reference to Fig. 1, the liquid crystal cell that utilizes the principle of STN LCD to make, liquid crystal molecule is parallel to the upper and lower base plate of glass when no-voltage drives, the levels liquid crystal molecule forms 240 degree distortions, with the compensation of levels polaroid, product is the faint yellow of ink silk screen printing layer.Liquid crystal molecule is perpendicular to upper and lower base plate when driven, product be surperficial polaroid with ink silk screen printing laminated become color (green).
Green picture stn liquid crystal display mainly contains following characteristic:
1. green picture stn liquid crystal display form and aspect see the following form:
2．
| ? | Backlight in vain | Do not show form and aspect | Show form and aspect |
| Brightness Lv | 357.4 | 88.9 | 28.22 |
| Form and aspect x | 0.2565 | 0.3283 | 0.2064 |
| Form and aspect y | 0.2453 | 0.449 | 0.3313 |
[0022] By data in the table as can be known, green picture stn liquid crystal display background color is faint yellow, shown in green.
2. each visual angle of green picture stn liquid crystal display shows evenly, the visual angle broad.
Claims (2)
1. green picture stn liquid crystal display, comprise an ito glass, following sheet ito glass, upper strata polaroid, lower floor's polaroid, liquid crystal, it is characterized in that, on last ito glass, apply Yellow ink silk-screen layer, on Yellow ink silk-screen layer, stick blue polaroid again and constitute the upper strata polaroid, lower floor's polaroid is through mode, reflective or semi-permeable polaroid, realizes the green picture display effect of faint yellow background.
2. green picture stn liquid crystal display according to claim 1 is characterized in that, described liquid crystal twist angle 240 degree, optical path difference 830nm.
