Abstract

The utility model discloses a 3D (three dimensional) raster display screen which comprises an LED array, a scatter plate and an ITO (indium tin oxide) glass plate. The LED array comprises a plurality of LED luminous bodies, and each LED luminous body comprises single LEDs in red, green and blue colors. The scatter plate is arranged in front of the LED array and scatters light emitted by the LED luminous bodies in the LED array. The ITO glass plate is arranged in front of the scatter plate, and raster stripes are arranged on the ITO glass plate. Images observed by a left eye and a right eye are different by the aid of a raster realized by the ITO glass plate, so that naked eye 3D effects are achieved. Besides, the LEDs serve as the luminous bodies, and the 3D raster display screen has high light-emitting brightness and is suitable for naked eye 3D application.

Description

The 3D grating display screen

Technical field

The utility model relates to bore hole 3D technology, relates in particular to a kind of LED grating display screen with 3D effect.

Background technology

3D is the abbreviation of three-dimensional, is exactly three-dimensional picture.And the 3D technology is exactly the technology of virtual three-dimensional, reaches a kind of technology of the aspect stereoeffects such as vision, the sense of hearing by the computing that utilizes computing machine.The 3D effect of realizing in film utilizes the binocular stereo vision principle exactly, makes spectators can obtain from screen the film of three dimensions sense vision imaging.

The 3D technology develops the history that arranged decades in market, really being applied to civil area has also had development for many years.And in recent years because the showing of all kinds of 3D films, 3D has become the new trend that video shows industry.Comprise at present 3D TV, 3D display and 3D projector, all come out, begin to popularize.Existing 3D technology majority needs the auxiliary of glasses, and is lower assisting of specific glasses, can watch the video of the 3D effect of playing on the screen.

But for media industry, the spectacle 3D effect there is no practical significance, and media industry is for not characteristic crowd's broadcast broadcast, can not allot glasses for each audience.Therefore, bore hole 3D technology is more meaningful for media industry.The picture that bore hole 3D technology namely utilizes certain mode that right and left eyes is watched there are differences, and forms the depth of field, thereby produces the stereoeffect of picture.3D will bring to the propagation of video media a revolution undoubtedly, if in track traffic, the bore hole 3D product such as using on the subway based on LED display will have vast potential for future development.

The utility model content

The utility model is intended to propose a kind of LED display that adopts grating technology, has the bore hole 3D effect.

According to an embodiment of the present utility model, a kind of 3D grating display screen is proposed, comprising: led array, scatter plate and ito glass plate.Led array comprises several LED luminophors, and each LED luminophor comprises the LED monomer of red, green, blue three looks.Scatter plate is arranged on the place ahead of led array, the light that the LED luminophor in the scatter plate scattering led array sends.The ito glass plate is arranged on the place ahead of scatter plate, is provided with grating fringe on the ito glass plate.

In one embodiment, the front surface of scatter plate is the plane, has a series of arc pits on the rear surface, the corresponding LED luminophor in the position of each arc pit, and the LED luminophor is placed in the described arc pit.

In one embodiment, the spacing of the LED luminophor on the led array is at 2～3mm.

In one embodiment, the grating fringe on the ito glass plate is vertical striped.

3D grating display screen of the present utility model utilizes the grating of ito glass plate realization so that the image that right and left eyes is observed is different, thereby reaches the effect of bore hole 3D.Simultaneously, the utility model as luminophor, has higher luminosity with LED, is suitable for bore hole 3D and uses.

Description of drawings

Fig. 1 has disclosed the structural drawing according to the 3D grating display screen of an embodiment of the present utility model.

Fig. 2 has disclosed the structure according to the LED luminophor of the 3D grating display screen of an embodiment of the present utility model.

Fig. 3 has disclosed the structure according to the led array of the 3D grating display screen of an embodiment of the present utility model.

Fig. 4 has disclosed the structure according to the ito glass plate of the 3D grating display screen of an embodiment of the present utility model.

Embodiment

It is human when real world is observed object, because two are on the different horizontal levels, namely there is the pupil spacing, so that the solid images that images of left and right eyes is observed is different, there is parallax between them, because the existence of parallax, by the processing of brains nerve, so that we can the perception three-dimensional world three-dimensional variation of the degree of depth, Here it is so-called 3D visual theory.Under the 3D display mode, in the time of should being shown by the image that left eye is seen, block right eye by grating or polaroid, in like manner, in the time of should being shown by the image that right eye is seen, block left eye by grating or polaroid.To be separated by the image that left eye and right eye are observed, make the effect of parallax, just can make the observer see 3D rendering.According to this principle, just can realize bore hole 3D technology.

The utility model proposes a kind of 3D grating display screen, the front end of this display screen has grating, and grating is that slice grid mode arranges, and can be arranged to the optical grating construction of corduroy formula.By these grating strias, just formed vertical slice grid pattern by their light, form " parallax barrier ".Under the stereo display pattern, in the time of should being presented on the screen by the image that left eye is seen, opaque striped can block right eye; In like manner, in the time of should being presented on the screen by the image that right eye is seen, opaque striped can block left eye, by the viewable pictures of left eye and right eye is separated, makes the onlooker see the 3D image.

Fig. 1 has disclosed the structural drawing according to the 3D grating display screen of an embodiment of the present utility model.As shown in Figure 1, this 3D grating display screen 100 has led array 102, scatter plate 104 and ito glass plate 106.Led array 102 comprises several LED luminophors 120.Fig. 2 has disclosed the structure according to the LED luminophor of the 3D grating display screen of an embodiment of the present utility model.Each LED luminophor 120 comprises the LED monomer of red, green, blue three looks: red LED monomer 121, green LED monomer 122 and blue led monomer 123.Three LED monomers are installed on the pedestal 124 jointly, and encapsulation forms LED luminophor 120.The LED monomer of three looks can be realized the colored effect that shows.The utility model adopts led array as light emitting source, can be so that whole screen be brighter, because 3D can cover the light of a part when showing, so that display brightness descends, use the LED of high brightness can effectively improve this problem.

In one embodiment, spacing between the LED luminophor 120 on the led array 102 is at 2～3mm, be each LED luminophor 120 and its interval between the adjacent LED luminophor 120 is in the scope of 2～3mm up and down, so design also is in order to improve the consideration of brightness.Fig. 3 has disclosed the structure according to the led array of the 3D grating display screen of an embodiment of the present utility model.
