Compared with the prior art, the black-background liquid crystal display with the high definition and the manufacturing technology thereof have the advantages that the background is black when no backlight exists, bright and reflective patterns are displayed clearly, and the contrast ratio is high; the background is black when the backlight is started, patterns with a color the same as that of the backlight are displayed, and the brightness is high; as a result, no matter whether the backlight exists or not, the contract ratio is high, the definition is high, and the effects of low power consumption, energy saving and power saving are achieved; by the adoption of the black-background liquid crystal display with the high definition, the TN mode and the STN mode can be manufactured; for the TN mode, the background is whiter, the contract ratio is higher, and the price is lower; for the STN mode, the visual angle is wider, and more contents can be displayed.
Description
Technical field
The present invention relates to display technology field, especially a kind of liquid crystal display.
Background technology
Liquid crystal display is a kind of flat-panel screens being widely used, and has the features such as low in energy consumption, slim body, lightweight and driving voltage be low.Liquid crystal display itself can not be luminous, relies on modulation ambient light to realize and show.Conventional liquid crystal display mode has the TN display mode of applicable low way driving and is applicable to the STN display mode that high way drives.Liquid crystal display is divided into the negative phenotype of the just aobvious and shallow calligraphy and painting face of dark-background of the dark picture of light background, and negative phenotype liquid crystal display (the especially liquid crystal display of black background) has higher contrast.But common common-black type liquid crystal display is very poor in contrast when backlight, cannot reach result of use.Along with the development of human sciences's technology, the needs of people's real life, various new display modes are developed successively.Under black background, the lcd technology of bright picture disply is also one of them.
Summary of the invention
The object of the present invention is to provide a kind of black background liquid crystal display and manufacturing process thereof with bright picture, utilize the feature of existing LCD production technology and the reflection of DBEF-A selective light, can produce the bright picture liquid crystal display of black background.Have and make simple, bright, picture disply advantage clearly.Make product have or not product when backlight can reach the effect of high-contrast, using when backlight, can also reach the effect of low-power consumption, energy-conservation, power saving, utilize existing LCD equipment and process to produce, make simple, cheap.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of black background liquid crystal display with bright picture, comprise polaroid, ito glass, frame, liquid crystal layer, lower polaroid, DBEF-A, in the middle of two ito glasses, by liquid crystal layer, separated, upper polaroid be arranged on upper strata ito glass outer with the parallel connection of upper strata ito glass, lower polaroid is arranged on the parallel connection of ito glass Wai Yu lower floor of lower floor ito glass, it is characterized in that, described upper polaroid adopts TN high-polarization polaroid or STN composite membrane, lower polaroid adopts high-polarization polaroid, at the outermost layer of lower polaroid, is pasted with DBEF-A diaphragm.
The key manufacturing technology of the black background liquid crystal display of described bright picture, adopts following steps:
1) upper polaroid adopts TN high-polarization polaroid or STN composite membrane; Display mode is TN pattern, and upper polaroid is used high-polarization transmission sheet; Display mode is STN pattern, and STN composite membrane is used the composite membrane of 580nm, 45 ° of compensation; Making display background is black;
2) lower polaroid adopts high-polarization polaroid, at the outermost layer of lower polaroid, is pasted with DBEF-A diaphragm; Realize the bright demonstration of black background;
3), during no-voltage, display presents black background; During making alive, present bright display frame.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention's background when without backlight is black, shows bright reflective pattern, clear patterns, good contrast; When backlight is opened, background is black, the pattern of display backlight color, and brightness is high.The contrast that can realize, have in the situation without backlight, picture is clear, and reaches the effect of low-power consumption, energy-conservation, power saving; Under black background, bright view display, can make TN pattern and STN pattern, and the background of TN pattern is whiter, and contrast is higher, and price is lower; STN pattern visual angle is wider, and displaying contents is more.
