Abstract
The utility model discloses a high-contrast black film LCD screen with dye liquid crystals. The LCD screen comprises an upper glass substrate and a lower glass substrate. A black film, an upper ITO conductive layer, an upper PI alignment layer, a liquid crystal layer, a lower PI alignment layer and a lower ITO conductive layer are arranged between the upper glass substrate and the lower glass substrate from the top to the bottom. The liquid crystal layer is provided with plastic balls for separation and is filled with dye liquid crystals. Edge sealing glue is used between the upper glass substrate and the lower glass substrate for sealing. The LCD screen uses the dye liquid crystals to substitute common liquid crystals of conventional LCD screens. As the dye liquid crystals can absorb light, blackness of the bottom color of the LCD screen is increased, light transmission is prevented in non-display areas, and the contrast and the view angle are increased.
Description
Technical field
The utility model relates to a kind of LCDs, particularly relates to a kind of high-contrast black film liquid crystal display screen with dye liquid crystal.
Background technology
Along with scientific and technological development, people are more and more higher for the requirement of LCDs, and one of leading indicator that contrast is LCDs need to be improved.
Existing black film liquid crystal display screen product, for improving contrast, is provided with Polarizer in top glass substrate and the outside surface of lower glass substrate, thus, has both increased the complicacy of production technology, has improved again the production cost of product.
Utility model content
The utility model object is to provide the black film liquid crystal display screen that a kind of manufacture craft is simple and contrast is high.
The technical solution adopted in the utility model is:
A kind of high-contrast black film liquid crystal display screen with dye liquid crystal, comprise top glass substrate and lower glass substrate, top glass substrate, between lower glass substrate, be provided with successively from top to bottom black film, upper ITO conductive layer, upper PI oriented layer, liquid crystal layer, lower PI oriented layer, lower ITO conductive layer, described liquid crystal layer has been provided with the plastic ball of interval action and has been filled with dye liquid crystal, described dye liquid crystal comprises positivity nematic liquid crystal and dichroic dye, between described top glass substrate and lower glass substrate, seal by edge sealing adhesive, gap between top glass substrate and lower glass substrate is 5-12 μ m.
As the improvement of technique scheme, the outside surface of described top glass substrate and lower glass substrate is provided with Polarizer, and the light transmission shaft of two Polarizers 11 is parallel to each other.
Another kind as technique scheme improves, and described top glass substrate or the outside surface of lower glass substrate are provided with Polarizer.
Further, the inside surface of described top glass substrate, lower glass substrate all plays the transparent silicon dioxide film of insulating effect with one deck.
A kind of high-contrast black film liquid crystal display screen with dye liquid crystal that the utility model provides has following beneficial effect:
(1) the utility model adopts dye liquid crystal to substitute the common liquid crystals of traditional LCDs, because dye liquid crystal can evenly absorb directive auroral poles polarization component, can increase LCDs background color blackness, avoid non-display area printing opacity, improve contrast and widen visual angle;
(2) the utility model, owing to having adopted dye liquid crystal, can remove the Polarizer of traditional LCDs or only establish a Polarizer, makes the structure of LCDs simpler.

Embodiment
Embodiment mono-
Referring to figs. 1 through Fig. 3, a kind of high-contrast black film liquid crystal display screen with dye liquid crystal of the present utility model, comprise top glass substrate 1 and lower glass substrate 2, top glass substrate 1, between lower glass substrate 2, be provided with successively from top to bottom black film 3, upper ITO conductive layer 4, upper PI oriented layer 5, liquid crystal layer, lower PI oriented layer 6, lower ITO conductive layer 7, described liquid crystal layer has been provided with the plastic ball 10 of interval action and has been filled with dye liquid crystal, wherein said dye liquid crystal comprises positivity nematic liquid crystal 8 and dichroic dye 9, between described top glass substrate 1 and lower glass substrate 2, seal by edge sealing adhesive 13, gap between top glass substrate 1 and lower glass substrate 2 is 5-12 μ m.The utility model is owing to having used the dye liquid crystal potpourri being made up of positivity nematic liquid crystal 8, dichroic dye 9, dye liquid crystal can evenly absorb directive auroral poles polarization component, can increase LCDs background color blackness, avoid non-display area printing opacity, improve contrast and widen visual angle.
In the present embodiment, described top glass substrate 1 and the outside surface of lower glass substrate 2 are provided with Polarizer 11, and the light transmission shaft of two Polarizers 11 is parallel to each other.The black film liquid crystal display screen of the present embodiment is to adopt the negativity that positivity nematic liquid crystal 8 is made to show LCD, in the time that on liquid crystal layer, ITO conductive layer 4, lower ITO conductive layer 7 are not switched on, the light that backlight module produces becomes linearly polarized photon through lower Polarizer 11, incide in liquid crystal layer, be positivity nematic liquid crystal 8 and dichroic dye 9 distortions of twisted nematic state, can not pass through upper deflection board 11, light tight; When being that when ITO conductive layer 4, lower ITO conductive layer 7 add voltage on liquid crystal layer, positivity nematic liquid crystal 8 rotates into vertical nematic state with dichroic dye 9, make light smoothly by upper deflection board 11.The utility model, by regulating the anglec of rotation of dye liquid crystal, is controlled the bright dark of LCDs, compares tradition and uses the negativity that VA liquid crystal is made to show LCD, the utlity model has the advantage that power consumption is little.
In addition, the inside surface of described top glass substrate 1, lower glass substrate 2 all plays the transparent silicon dioxide film 12 of insulating effect with one deck, the impact for the sodion of isolation glass composition on liquid crystal molecule.
The LCDs of embodiment mono-is provided with Polarizer 11 owing to being provided with black film 3, dye liquid crystal and upper and lower surface, so can reach the contrast of 80:1.
Embodiment bis-
With reference to Fig. 4, embodiment of the present utility model bis-is with embodiment mono-difference, and LCDs is only provided with one deck Polarizer 11 in described top glass substrate 1 or the outside surface of lower glass substrate 2.The utility model, owing to having adopted dye liquid crystal to substitute the common liquid crystals of traditional LCDs, makes LCDs have high-contrast, so can remove the Polarizer 11 of one side, makes product structure simpler.
