Description

A kind of Multifunctional stand volumetric display

technical field:

The utility model belongs to field of electronic display, is specifically related to a kind of multifunctional stereo display.

background technology:

General display is divided by its function as two kinds of flat-panel screens and three-dimensional displays, and wherein three-dimensional display is divided into again three-dimensional (3D) displays of two viewpoints that need to wear glasses and without two kinds of many viewpoints naked-eye stereoscopic displays of wearing spectacles.The former comprises electronic shutter spectacle and polarising glass formula, the latter take slit grating formula and cylindrical mirror board-like as main.Various types of display function purposes are as follows:

Flat-panel screens: be mainly used in watching plane video image or figure etc., include but not limited to the terminal display applications such as radio and television, computing machine.

Two viewpoint three-dimensional displays: adopt electronic shutter glasses or polarising glass, be mainly used in watching stereoscopic video images or figure, information source can from but be not limited to 3D broadcast TV program and three-dimensional film program, the latter can use computing machine or server to play;

Many viewpoints naked-eye stereoscopic display: without wearing any glasses, bore hole is watched many viewpoints (at present common take 8 viewpoints as many) image graphics program.Due to the program of its broadcasting and existing radio and television and computer architecture incompatible, generally adopt the special program of making to form, and be used for the fields such as advertisement promotion.

Aforesaid completely not compatible above various up to now according to the various displays of viewing function or purposes, generally speaking, two viewpoint 3D displays and common 2D display can be compatible, but cannot watch many viewpoints bore hole stereo-picture, a small amount of small-sized multi-viewpoint three-dimensional display can adopt liquid crystal shutter to control, realize the function that common 2D watches, but cannot watch the three-dimensional program of two viewpoints.

In the manufacture of small-sized controlled many viewpoints of slit grating formula naked-eye stereoscopic display, the cost of a set of controllable liquid crystal slit grating plate is very high, and very strict to the quality of fit of display panel, a same controlled slit grating plate, for same size, can not realizing of different manufacturers manufacture is general, and this has just further increased manufacturing cost and has further limited the scope of applying.

utility model content:

The purpose of this utility model is to provide a kind of based on liquid crystal slit grating technology, realizes the Multifunctional stand volumetric display that common 2D, two viewpoint stereo displays and the stereo display of many viewpoints bore hole are integrated, and accomplishes a tractor serves several purposes, has expanded the range of application of stereo display.

To achieve these goals, the utility model is by the following technical solutions: a kind of Multifunctional stand volumetric display, stereo display mode is electronic shutter formula or polarization type, it contains the display lighting face that illumination mode is liquid crystal, plasma, electroluminescence, organic electroluminescent OLED or LED giant-screen, it is characterized in that: in face of display lighting, face is provided with a liquid crystal shutter shield plates, described liquid crystal shutter shield plates is the black and white interval striped that is oblique or vertical, forms the liquid crystal shutter shield plates of slit grating.

Further, liquid crystal shutter shield plates or for liquid crystal shutter shield plates function while closing the grating of display display plane program or the three-dimensional program of two viewpoints be and open shape completely, or the grating that display can be realized many viewpoints bore hole three-dimensional display function while opening for liquid crystal shutter shield plates function at an angle block shape.

The beneficial effect that the utility model produces is: the slit grating plate of manufacturing under the technical conditions that the utility model guides, not only go for the display that different manufacturers is manufactured, even can use the display that is slightly less than slit grating board size in different manufacturers manufacture, this has just further expanded its range of application, thereby solved, single display device is realized common 2D, two viewpoints are three-dimensional and the problem of many viewpoints bore hole stereo display, has realized a tractor serves several purposes.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further detailed.

As shown in Figure 1, get any can be compatible the two viewpoint three-dimensional displays 1 that show of common plane, illumination mode can be liquid crystal, plasma, electroluminescence, organic electroluminescent OLED and LED giant-screen etc., stereo display mode can be electronic shutter formula or polarization type, keep original 3D mode constant, before the light-emitting area of display 1, install a liquid crystal shutter shield plates 2 additional, this shield plates 2 can produce the needed black and white strip of barrier.

As shown in Figure 2, when the barrier function of shield plates is closed, grating is full open position, now display screen presents the situation that there is no this shield plates, its principle is illustrated in figure 4 slit grating and opens schematic diagram completely, at this moment can according to program source, be controlled by display the three-dimensional program of display plane program or two viewpoints.

As shown in Figure 3, when the barrier function of shield plates is enabled, grating is strip occlusion state, now according to program source, shows the three-dimensional program of corresponding many viewpoints bore hole, and display can be realized many viewpoints bore hole three-dimensional display function.

As shown in Fig. 5-7, the liquid crystal shutter shield plates before display lighting panel can be realized the black and white interval striped that is oblique or vertical, forms slit grating, and the width of grating, black and white bar interval and oblique angle etc. all can freely convert.As shown in Figure 8, Figure 9.Fig. 8 left side is that width increases signal, and the right side is that width reduces signal; Fig. 9 left side is that spacing increases signal, and the right side is that spacing reduces signal, and degree of tilt is also to change arbitrarily, owing to converting arbitrarily, so liquid crystal shutter shield plates goes for various display screens, thereby realizes the demonstration object of one-machine-multi-function.

When liquid crystal display baffle is manufactured, the granularity of shield plates pixel is less, and the resolution of liquid crystal shutter shield plates is higher, and transform effect is better, and particularly oblique lines neat in edge, converts random degree high, otherwise instead.Its principle is as shown in Figure 10-11, generally for high-definition television, more than being preferably in 8K * 4K, for the display of other resolution, shield plates horizontal and vertical resolution generally should be not less than respectively 4 times of corresponding display horizontal and vertical resolution.

According to the liquid crystal shutter shield plates of the utility model manufacturing, not only can be applied to the discrepant display screen of other pixels that measure-alike but Pixel Dimensions (or pixel granularity) is different or cause because of manufacturing firm's difference, also can be applied to the display screen that size is less than liquid crystal shutter shield plates, also go for vertically showing or claiming vertical demonstration.

Above embodiment is only for illustrating preferred implementation of the present utility model; but the utility model is not limited to above-mentioned embodiment; in the ken that described field those of ordinary skill possesses; any modification of doing within spirit of the present utility model and principle, be equal to and substitute and improvement etc.; it all belongs to category of the present utility model, within all should be encompassed in the technical scheme scope that the utility model asks for protection.
