Abstract
The invention discloses a 3D television based on an electronic grating, which can watch a 3D effect without any auxiliary equipment; it is characterized by comprising: the liquid crystal display screen comprises a liquid crystal display screen and a transparent screen arranged on one side of a light emergent surface of the liquid crystal display screen. By the mode, the problem of color crosstalk in the 3D television can be reduced, the manufacturing is easy, the manufacturing efficiency is improved, and the manufacturing and production cost is reduced.
Description
Technical Field
The invention relates to the field of electronics, in particular to a 3D television with electronic gratings.
Background
The appearance of the stereoscopic display technology is another technical revolution after black and white are replaced by colors in the image field, and naked eye stereoscopic display is a development trend of the display industry. The naked eye 3D display technology is the latest and leading-edge high-tech technology in the image industry, changes the visual fatigue brought to people by the traditional plane image and is a qualitative change. The technology for realizing naked eye 3D display mainly includes two technologies, namely, light barrier type and cylindrical lens type (also called micro cylindrical lens type), and the latter does not affect the screen brightness as the former does, so the display effect of the cylindrical lens technology is better. The lenticular 3D technique positions the image plane of the liquid crystal screen at the focal plane of the lens so that the pixels of the image beneath each lenticular lens are divided into several sub-pixels, and the lens can project each sub-pixel in a different direction. The eyes then see different sub-pixels from different angles.
The naked eye 3D display device adopting the cylindrical lens 3D technology utilizes the characteristic that two eyes of a person have parallax error to obtain a display system with vivid images of space and depth. The naked eye stereoscopic image is deeply favored by consumers due to the real and vivid expressive force, the environment infectivity and the strong shocking visual impact.
However, in the naked-eye 3D display device adopting the lenticular 3D technology in the prior art, there is a strict spatial position relationship between the column pixels of the liquid crystal panel and the lenticular array film. Because the physical size of a single pixel and the cylindrical lens array is extremely small, if the installation has tiny deviation, the transmission path of emergent light can be changed, and the independent visual area is deformed to seriously influence the stereoscopic display effect. Moreover, the relative position and the sight angle of the optical device cannot be accurately adjusted by adopting naked eyes for assembly, and the mechanical precision of installation is difficult to determine; and the instruments dedicated to assembly are very expensive. In order to realize the permanent fixation of the assembly of the column pixels and the cylindrical lens array diaphragm and reduce the assembly cost, a naked eye 3D display device with high assembly efficiency and low cost and an assembly method thereof are needed.
Disclosure of Invention
The invention mainly solves the technical problem of providing a 3D television based on an electronic grating, and can solve the problems of high assembly cost and low efficiency in the existing 3D television.
In order to solve the technical problems, the invention adopts a technical scheme that: the 3D television based on the electronic grating is provided, and 3D effect can be watched without any auxiliary equipment; it is characterized by comprising: the system comprises a liquid crystal display screen, a transparent screen arranged on one side of a light emergent surface of the liquid crystal display screen, and 3D image processing software. The liquid crystal display screen has full high definition, 2K and 4K RGB color values. The size of the transparent screen is the same as that of the liquid crystal display screen. The slit grating made of the transparent screen rotates 12.53 degrees clockwise. The transparent screen is superposed with the image plane of the liquid crystal display screen. The invention has the beneficial effects that: the invention utilizes the full transparent screen to manufacture the 3D display device, has simple operation, only needs to open the manufactured 3D image on the display screen, then manufactures the slit grating on the transparent screen to match the data until the satisfied 3D effect is seen, and has little allocation and installation relation with hardware.

Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
Referring to fig. 1 and 2, an embodiment of the present invention includes:
the utility model provides a 3D TV based on electronic grating, assembly cost is high among the solution current 3D TV, the problem of inefficiency, and application transparent screen has replaced traditional grating (lenticular lens, slit grating), and traditional grating need be mounted to the image, comes counterpoint the image and pastes according to standard angle, whether the in-process of pasting does not have the bubble, dirty point, can not play a series of problems such as bubble in the use. The specific implementation mode is that a transparent flat plate with the same size as the display screen is selected to manufacture the grating, and two display screens with the same size are directly assembled.
In another embodiment, the two screens are firstly installed in the frames with the same size, the aluminum alloy frames which can be purchased in the market can be used, a straight line is made in the display screen according to 12.53 degrees, a straight line graph with the same angle as the display screen is made in the transparent screen, and the angle of the straight line graph is measured (photoshop). The correction of the two screens is completed.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
