Abstract
The invention discloses an anti-peep liquid crystal display. The liquid crystal display comprises a liquid crystal panel and circular polarized glasses matched with the liquid crystal panel, wherein the liquid crystal panel comprises a color film substrate and an array substrate which are arranged oppositely, and a liquid crystal layer arranged between the color film substrate and the array substrate; and a first 1/4 phase delay film and a first polarizer are arranged on the array substrate in turn. The liquid crystal display can prevent a picture on a display screen from being peeped by other people.
Description
Technical field
The present invention relates to LCD and make field, particularly a kind of peep-proof LCD.
Background technology
Along with the development of infotech society, people have obtained growth to the demand of display device.In order to satisfy this demand, nearest several kinds of panel display apparatus have all obtained swift and violent development like liquid crystal indicator (LCD), organic light-emitting display device (OLED), plasm display device (PDP).In panel display apparatus, liquid crystal indicator is because its weight is low, volume is little, advantage of low energy consumption is progressively replacing organic light-emitting display device and plasm display device.
The characteristics big based on angle of visibility, that response speed is fast, VA (Vertical Alignment; Vertical orientation) display mode has become one of present large scale liquid crystal TV main flow display mode; Tradition VA generally adopts line to show partially, because rotatory polarization is consistent for the gamma curve of liquid crystal all directions, so with respect to the line polarisation; Adopt the rotatory polarization liquid crystal panel can have higher transmittance for the VA pattern, cardinal principle is following:
In the processing procedure of liquid crystal indicator, tending between two polaroids in front and back, respectively add a slice 1/4 bit phase delay film, is rotatory polarization with the light that reaches through liquid crystal layer.
As shown in Figure 1, backlight 11 first polaroids 12 by liquid crystal panel 10 form and the consistent line polarisation in first polaroid, 12 polarization directions, and then through 1/4 bit phase delay film 13; Form left-handed (or dextrorotation) rotatory polarization; Through array base palte 14, liquid crystal layer 25 and color membrane substrates 15 convert rotatory polarization into the line polarisation through the 3 1/4 bit phase delay film 16 again; Again through the 3rd polaroid 17; Be applied to the variation of voltage on the liquid crystal layer 25 through adjustment, thereby produce the bright dipping gray scale variation, emergent light 18 forms picture on the surface of liquid crystal panel 10.
Along with the development and the raising of liquid crystal indicator, various portable personalised digital products constantly occur, and therefore can operate whenever and wherever possible, and are very convenient, and when still using in public places, the data information on the display screen is very easily spied on and leaked.
Summary of the invention
Goal of the invention: the problem and shortage to above-mentioned prior art exists, the purpose of this invention is to provide a kind of peep-proof LCD, can prevent that other people from spying on the picture on the display screen.
Technical scheme: for realizing the foregoing invention purpose; The technical scheme that the present invention adopts is a kind of peep-proof LCD; Comprise liquid crystal panel; This liquid crystal panel comprises color membrane substrates and the array base palte that is oppositely arranged, and is arranged in the liquid crystal layer between said color membrane substrates and the array base palte, only on said array base palte, is provided with the one 1/4 bit phase delay film and first polaroid successively; Also comprise the circle inclined to one side glasses suitable with said liquid crystal panel.This technical scheme only is provided with 1/4 bit phase delay film and polaroid on array base palte, after light is through Polarizer and 1/4 bit phase delay film on the array base palte, be left-handed (or dextrorotation) rotatory polarization; No matter liquid crystal panel is the state of switching on or not switching on; Light all can directly be worn in public by array base palte and color membrane substrates, presents the state that confusion can't moulding, sees white picture when making the observer not be with the inclined to one side glasses of circle; Be beyond recognition the image information of display screen, to reach the effect of peep-proof.When the needs normal viewing, wear the observation image information that the inclined to one side glasses of dextrorotation (or left-handed) circle can be correct, and do not have the head pose requirement for the beholder, observe equal bias free through all angles.
The another kind of technical scheme that the present invention adopts is a kind of peep-proof LCD; Comprise liquid crystal panel; This liquid crystal panel comprises color membrane substrates and the array base palte that is oppositely arranged; And be arranged in the liquid crystal layer between said color membrane substrates and the array base palte, only on said array base palte, be provided with the one 1/4 bit phase delay film and first polaroid successively; Also comprise and be installed in the preceding movable Polarizer of said liquid crystal panel.This technical scheme only is provided with 1/4 bit phase delay film and polaroid on array base palte, after light is through Polarizer and 1/4 bit phase delay film on the array base palte, be left-handed (or dextrorotation) rotatory polarization; No matter liquid crystal panel is the state of switching on or not switching on; Light all can directly be worn in public by array base palte and color membrane substrates, presents the state that confusion can't moulding, makes the bore hole observer see white picture; Be beyond recognition the image information of display screen, to reach the effect of peep-proof.When the needs normal viewing, only a movable Polarizer need be installed before display screen, can bore hole watch.
Said movable Polarizer can comprise organic glass, the 2 1/4 bit phase delay film and second polaroid that sets gradually.
Beneficial effect: the present invention not only can peep-proof maintains secrecy, and liquid crystal panel only is provided with a polaroid and 1/4 bit phase delay film, has both reduced processing cost relatively, has simplified processing procedure again, improves the yield of product; And can reduce the use amount of polaroid,, also can alleviate the weight of LCD relatively except that reducing the Material Cost.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the present invention; Should understand these embodiment only be used to the present invention is described and be not used in the restriction scope of the present invention; After having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
Embodiment 1:
As shown in Figure 2, backlight 11 first polaroids 12 by liquid crystal panel 10 form and the consistent line polarisation in first polaroid, 12 polarization directions, and then through 1/4 bit phase delay film 13; Form left-handed (or dextrorotation) rotatory polarization; Rotatory polarization is through liquid crystal layer 25 and color membrane substrates 15 directly outgoing of back, owing to not having the 3 1/4 bit phase delay film 16 and the 3rd polaroid 17, so when bore hole direct viewing display screen; Because pixel does not have the variation of GTG; The observer can't watch image information, need wear the inclined to one side glasses 19 of circle and watch, and play peep-proof effect of the present invention.
Embodiment 2:
As shown in Figure 3, the difference of present embodiment and embodiment 1 is: when the needs normal viewing, no longer wear the inclined to one side glasses 19 of circle, but movable Polarizer 21 is installed before liquid crystal panel 10, can bore hole watch.This movable Polarizer 21 can be on organic glass 22, to attach the 2 1/4 bit phase delay film 23 and second polaroid, 24 formations successively.
