Abstract
The utility model relates to a liquid crystal display with a red picture. By utilizing the optical property (selective reflection) of an RDF-C type polaroid and a red composite film polaroid in a matching way, the liquid crystal display realizes the display effects that when a backlight source is closed, a red picture under a white background is displayed, and when the backlight source is opened, a white picture under a red background is displayed. The picture is bright, and the contrast ratio is good. The current STN (Super Twisted Nematic) equipment and process can be used for production, and the price is low. Compared with the prior art, the liquid crystal display has the benefits that when the backlight source of the red liquid crystal display is closed, the background is white, the displayed picture is red, bright and clear, and the contrast ratio is good; when the backlight source is opened, the background is red, the displayed picture is white, and the contrast ratio is good. Under the condition with the backlight source or without the backlight source, the contrast ratio is good, and the picture is bright and clear. The red liquid crystal display can display the red picture under the white background and can also display the white picture under the red background.
Description
Technical field
The utility model relates to display technology field, especially a kind of liquid crystal display with red picture.
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.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.
Along with the development of human sciences's technology, the needs of people's real life, various new display modes are developed successively, and red liquid crystal display is also one of them.
Utility model content
The purpose of this utility model is to provide a kind of liquid crystal display with red picture, utilize the optical characteristics (selection reflectivity) of RDF-C type polaroid, and mate the red polaroid of TN or the red composite membrane polaroid of STN, the display effect of white picture disply under red background while having realized the red picture disply under white background when backlight is closed, backlight unlatching.Picture is bright-coloured, good contrast.Can use existing STN equipment and process to produce, low price.Have and make simply, good contrast, visible angle are wide, background and the uniform feature of Show Color.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of liquid crystal display with red picture, comprise polaroid, ito glass, frame, liquid crystal layer, lower polaroid, in the middle of two ito glasses, separated by liquid crystal layer, upper polaroid is arranged on the outer connection parallel with upper strata ito glass 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 red polaroid of TN type or the red composite membrane polaroid of STN type, and lower polaroid adopts RDF-C type polaroid.
Compared with prior art, the beneficial effects of the utility model are:
When red liquid crystal display backlight source is closed, background, for white, shows red picture, and picture is bright-coloured, clear, good contrast; When backlight is opened, background is red, the picture of display white, good contrast.Can realize the contrast having had in the situation that has or not backlight, picture is bright-coloured, clear.Red liquid crystal display, not only can realize the red picture disply of white background but also can realize red background white picture disply.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is the displaying principle figure of backlight while closing.
Displaying principle figure when Fig. 3 is backlight unlatching.
Polaroid under the upper polaroid 2-ITO of 1-glass 3-frame 4-liquid crystal layer 5-
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated:
As shown in Figure 1, a kind of liquid crystal display with red picture, formed by upper polaroid 1, ito glass 2, frame 3, liquid crystal layer 4 and lower polaroid 5, in the middle of two ito glasses 2, separated by liquid crystal layer 4, upper polaroid 1 is arranged on the outer connection parallel with upper strata ito glass 2 of upper strata ito glass 2, lower polaroid 5 be arranged on lower floor's ito glass 2 outer with lower floor's ito glass 2 parallel connections, described upper polaroid 1 adopts the red polaroid of TN or the red composite membrane polaroid of STN, and lower polaroid 5 adopts RDF-C type polaroid.
The key manufacturing technology of the liquid crystal display of red picture, adopts following steps:
1) upper polaroid 1 adopts the red polaroid of TN or the red composite membrane polaroid of STN; Display mode is TN pattern, and upper polaroid uses red polaroid; Display mode is STN pattern, and STN composite membrane uses the composite membrane polaroid of 580nm, 45 ° of compensation;
2) lower polaroid 5 adopts RDF-C type polaroid;
3) when backlight is closed, display presents white background, red display picture; When backlight is opened, the display background that takes on a red color, white displays picture.
Embodiment 1:
When backlight is closed, as shown in Figure 2:
In the time that backlight is closed, in the time that no-voltage drives, liquid crystal molecule is parallel to the upper and lower base plate of glass, and levels liquid crystal molecule forms 90 degree or 240 degree distortions, and with upper and lower polaroid compensation, product is white.In the time having voltage to drive, liquid crystal molecule is perpendicular to upper and lower base plate, and product viewing area is red picture.
1) when no-voltage: P light is absorbed, S light becomes P light through liquid crystal, meets RDF-C reflection, then becomes S light through upper polaroid through liquid crystal, presents white background effect, as Fig. 2 dotted line right side.
2) when making alive: P light is absorbed, S light is through upper polaroid, liquid crystal, lower polaroid, and light is absorbed, and presents red picture effect, as Fig. 2 dotted line left side.
Embodiment 2:
When backlight is opened, as shown in Figure 3:
In the time that backlight is opened, in the time that no-voltage drives, liquid crystal molecule is parallel to the upper and lower base plate of glass, and levels liquid crystal molecule forms 90 degree or 240 degree distortions, and with upper and lower polaroid compensation, light is absorbed by upper polaroid, and product is red light tight product.When have voltage drive time liquid crystal molecule perpendicular to upper and lower base plate, the upper and lower polaroid of light transmission, form backlight color (white) picture disply.
1), when no-voltage: P light is reflected, S light becomes P light through lower polaroid, liquid crystal, meets red composite membrane and is absorbed, and presents red background effect, as Fig. 2 dotted line right side.
2), when making alive: P light is reflected, S light, through lower polaroid, liquid crystal, upper polaroid, presents white picture effect.
Ito glass substrate is selected the ito glass substrate of thinner thickness, as Fig. 2 dotted line left side.
