Naked-eye 3D display system capable of carrying out lateral and vertical display

Abstract

The invention reveals a naked-eye 3D display system capable of carrying out lateral and vertical display, and the system comprises a signal processing device, an image display device and an optical grating image-splitting device, wherein the optical grating image-splitting device is arranged in an inclined manner. The system can achieve lateral-screen display, and can carry out anticlockwise 90-degree rotation to achieve vertical-screen display, the optical grating is arranged to be inclined towards the right side, and compared with the vertical-screen display of a 3D video signal, the lateral-screen display of the 3D video signal enables a single viewpoint image to make 90-degree clockwise rotation and the viewpoint arrangement position is not changed; or the system can achieve lateral-screen display, and can carry out clockwise 90-degree rotation to achieve vertical-screen display, the optical grating is arranged to be inclined towards the left side, and compared with the vertical-screen display of the 3D video signal, the lateral-screen display of the 3D video signal enables the single viewpoint image to make 90-degree anticlockwise rotation and the viewpoint arrangement position is not changed. The system provided by the invention can achieve the lateral-screen or vertical-screen naked-eye 3D display according to the needs, and meets the demands of various applications. The system can improve the 3D visual resolution and a 3D spatial effect, and can effectively reduce the design complexity.

Description

technical field [0001] The invention belongs to the technical field of naked-eye 3D display, and relates to a naked-eye 3D display system, in particular to a naked-eye 3D display system capable of displaying horizontally and vertically. Background technique [0002] With the rise of 3D display technology and products, naked-eye 3D display technology has become the focus of attention. Glasses-free 3D can directly watch immersive and realistic 3D effects without additional auxiliary equipment, and has become the main development direction of new display technology. It has been widely used in film and television entertainment, advertising media, exhibitions, engineering design, education and teaching and other fields. At present, naked-eye 3D display based on flat panel display has become the mainstream of naked-eye 3D display due to its advantages in technology maturity, cost and industrial chain support. The multi-view glasses-free 3D display system based on flat panel displ...

Problems solved by technology

[0003] Since the multi-view glasses-free 3D display will reduce the physical resolution of the display device, the R, G, and B sub-pixels that make up the pixel are usually used to improve the visual resolution, and the R, G, and B sub-pixels of most LCD screens are Horizontally arranged vertical rectangular areas, so the mainstream of multi-view glasses-free 3D display is horizontal screen display, which cannot fully meet the requirements of advertising media, exhibitions and other applications. Vertical screen display is often required in advertising media, exhibitions and other fields

Using R, G, and B sub-pixels arranged horizontally on the LCD screen to design a vertical screen naked-eye 3D display system is far more complicated than a horizontal screen naked-eye 3D display system, especially the balance design between the number of viewpoints and resolution

[0004] Given that both horizontal and vertical screen displays are indispensable display methods for naked-eye 3D display, designing a naked-eye 3D display system that can display horizontal and vertical screens on demand is the best way to meet the above application requirements; however, today's naked-eye 3D display systems None of the above functions
