Abstract

The utility model relates to a liquid crystal shutter display device. A display screen is mainly composed of a first light deflection plate, a base plate, a direction-matching layer, a liquid crystal layer, a second direction-matching layer, a second base plate, a second light deflection plate, etc., which are repetitively overlapped in sequence and form an integral structure. When different light deflection plates and base plates are matched with different direction-matching layers of absorbing axial angles, a structure which has an effectively expanded lightproof range is formed. Insulation layers is additionally arranged between the direction-matching layers and the base plates for electric conduction and insulation. With the overlapping structure of a plurality of liquid crystal layers and sharper stereoscopic images that are formed by integral shutter imaging technique, the purpose of high image quality can be achieved.

Description

The liquid crystal shutter display

The utility model relates to a kind of liquid crystal shutter display, for reaching high light-proofness, and effectively bring into play the technology of high-quality three-dimensional imaging, by the different physical characteristics of different stack design, each layer such as Polarizer, substrate, both alignment layers, liquid crystal layer with and the operating type that can control respectively, make the effect that presents visual effect and shading better, in order to the lifting of image quality, the more clear purpose that reaches high-quality imaging.

At present general alleged shutter structure can be divided into the structural form of mechanical type and electronic type, wherein, mechanical structure, be the used structure of general camera, but so structure can't be in response to the demand on the three-dimensional imaging, therefore develop the shutter structure that electronic type, with the demand that cooperates three-dimensional imaging but by still having many shortcomings to exist on its structure and on actual the use at the shutter structure of this electronic type at present, but be the structure of electronic type shutter light-proofness, but the scope of its shading ten minutes is limited, shading scope that can be certain is only about 0 to 5 degree, as shown in Figure 5, this shading scope 1, it is non-to be a comprehensive line of vision, therefore the scope of visual angle and contrast has following shortcoming in fact, such as:

1. can't know and see three-dimensional imaging: because of generally having the LCD that its shutter shows, its shaded effect is not good, cause unnecessary image residue and make image overlapped, image overlaps promptly to be had the ghost image generation and unsharp shortcoming takes place, so necessity of improvement is arranged.

2. only can develop on special angle and not meet user demand: just there is the deficiency of line of vision, visual angle and contrast in its LCD with shutter itself, and cause have only certain orientation, certain angle and the contrast of certain colour system thereof and video picture, but user's viewing angle then is arbitrarily to move, therefore when the user moves to outside the scope accidentally, its video picture must be difficult to the quality that reaches required.

3. the discomfort that very easily causes unnecessary fatigue or vision to adjust: by being limited in scope in shading, and make its left eye also as seen reach the image of right eye, the then identical visible image that reaches left eye of right eye, make when the visual centre imaging, cause unnecessary overlapping shortcoming, though still can allow brain produce stereoscopic sensation, but still have many ghosts to produce, except that the uncertain shortcoming of the imaging with preceding paragraph, promptly general alleged ghost phenomenon, more cause unnecessary cerebral and the pressure on the vision system, therefore very easily produce the fatigue on the optic nerve,, can't watch for a long time so general stereopsis is viewed and admired, after watching for a long time, by being poor still, the difference on the degree is arranged, after system adapts to its imaging in human visual nerve and the brain than human vision system idiomorphism imaging effect in its imaging, when replying general state, by tired, need a period of time in the answer, even revolve generation dusk at optic nerve, especially more obvious with elder person and child, therefore truly have necessity of improvement.

Fundamental purpose of the present utility model is to provide a kind of liquid crystal shutter display, it had several substrates, Polarizer and liquid crystal layer with compound and complementations that is superimposed with each other such as different lines of vision, visual angle and contrasts, effectively shading, and the image that the liquid crystal shutter of three-dimensional imaging is demonstrated has more clear more three-dimensional quality to present.

For achieving the above object, the utility model is taked following design proposal: this liquid crystal shutter display has Polarizer, substrate, both alignment layers liquid crystal layer, and aforementioned each layer is stacked in regular turn, the overlapping integrator of laying equal stress on, and collocation becomes the structure of combined type mutually.

Its structure is provided with Polarizer in regular turn by passing through for relative light wave, again through transparent substrate so that the image light wave can pass through smoothly, and be provided with both alignment layers in addition in substrate lower floor.

In the utility model, below liquid crystal layer, have laminar substrate in addition, and have frame glue to be encapsulated in the liquid crystal layer periphery.Make between substrate and frame glue the framework that forms sealing, pour into for liquid crystal and wherein form liquid crystal layer, the frame glue that has substrate to cooperate and can intercept liquid crystal to leak outside below liquid crystal layer stops, in case the liquid crystal of liquid crystal layer leaks outside, and again can fixed sturcture.

In the utility model, described each layer is twice superimposed setting in regular turn.

In the utility model, each layer is repeatedly superimposed setting in regular turn.

In the utility model, substrate is made by glass or polyoxyethylene terephthalic acids material.

In the utility model, the windup-degree of liquid crystal layer is more than or equal to 0 degree, promptly reverses or does not reverse.

In the utility model, the overlapped way of each layer adopts the mode of whole stickup of transparent adhesive tape material.

In the utility model, the mode that the overlapped way of each layer adopts transparent adhesive tape material periphery to paste.

In the utility model, the mode that the overlapped way of each layer adopts nontransparent glue material periphery to paste.

In the utility model, can be provided with conductive layer and insulation course in addition between substrate and both alignment layers.
