Figure1a. The parallax of the left and right eyes forms 3D vision; Figure1b. Polarization beam splitting; Figure 1c Time series splitting. TCL naked-eye 3D TV does not need special glasses to split light. Instead, a special cylindrical lens is added to the LCD screen, and the natural splitting effect of the cylindrical lens is used to separate the left and right eye images, so that viewers can obtain more comfortable stereoscopic vision.
Figure 2a. Cylindrical lens screen Figure 2b. Cylindrical lens beam splitting figure 2c. The cylindrical lens separates the left-eye and right-eye images. Naked 3D TV-TCL adopts the following unique technology: 1. High transmittance and high precision cylindrical lens technology. It can send specially processed 3D video images and display them at different angles on the LCD panel behind it, so that users can display 3D stereoscopic images even when they watch them at different angles. 2.8 view synthesis algorithm TCL 3D-TV adopts the patented cylindrical mirror 8 view synthesis algorithm, which is briefly described as follows. The stereoscopic video input to the display is either from a multi-channel stereoscopic camera composed of eight sub-cameras, or from eight sub-images obtained by simulating eight sub-cameras with computer drawing software.
Figure 3. The stereoscopic image input to the display consists of eight sub-images. In order to truly and naturally display stereoscopic images that can be viewed from multiple angles with these eight sub-images, it is necessary to encode and synthesize the LCD images behind the cylindrical lens. Take Figure 4 as an example. The original picture is three square figures of R, G and B, and the gray level gradually changes from 10% to 50%. In order to display these images on an ordinary LCD screen, it is only necessary to follow the middle of the screen, that is, R 1, R2, R3, R4, R5, g 1, g2, g3, g4, g5 and g2. In order to restore the image correctly on the LCD stereoscopic display screen with cylindrical lens, it is necessary to re-encode and rearrange the original image with software. The rearrangement methods are: r 1, g 1, b 1, R2, G2, B2, R3, G3, B3, R4, G4, B4, R5, G5, B5. In this way, the re-encoded image is refracted by the cylindrical lens and then restored to the original image in the observer. The 8-view synthesis algorithm of cylindrical mirror uses a similar method to rearrange the input images behind the cylindrical mirror to obtain the most natural 2D/3D image quality.
Figure 4. The images input to the display are rearranged behind the cylindrical mirror.
New technology of multi-angle panoramic 3D
The most fatal defect of naked-eye 3D is the viewing angle. Generally, there are only two or three perspectives, and you can't see it at all. This is the biggest challenge facing the entire 3D industry at present. For practical application, 3/9/ even (3*9)27 viewpoints are not enough.
Multi-angle mirror imaging technology fundamentally solves the problem of multi-angle viewing, and stereo vision can be obtained at any angle or moving position.
Product characteristics
Based on the unique N-view algorithm and high-precision technology, the naked-eye 3D TV -TCL has advantages over other products in stereoscopic effect, mainly in the following aspects: 1, no need to wear professional glasses to watch 3D, high transmittance and no loss of brightness; 2, the stereoscopic impression is outstanding, the visual impact is strong, the image is clear, the edge contour is good, and there is no ghosting; 3. Wide viewing angle and many viewing points. It is easy to get the best viewing position at will and meet the needs of many people. 4. Built-in integrated design concept, European and American design style, simple and generous. 5. Built-in industrial 3D playback equipment can fully meet the requirements of 7*24 hours playback. 6.TCL's unique "2-to-N" real-time video conversion technology supports the playback of ordinary 3D video programs, with outstanding stereoscopic effect and clear image conversion effect. 7. Naked-eye 3D TV can be applied to various professional display fields-TCL not only needs to develop professional naked-eye 3D display technology, but also needs to develop supporting industry solutions and apply them to different professional display fields to broaden the application of naked-eye 3D TV market. While focusing on the research of 3D display technology, TCL also launched a variety of naked-eye 3D solutions: 1, naked-eye 3D media advertising solutions. Based on TCL's self-developed e-show information publishing system and Internet platform, the solution adopts centralized control and unified management, and realizes the remote broadcast control mode of naked-eye 3D advertisements at the terminal. The scheme has the characteristics of no need for manual attendance, two-level review mechanism of content, subtitle scrolling and fully intelligent playback function. , which greatly facilitates the management of advertising operators or enterprise clients, improves the work efficiency and quickly achieves the advertising effect.
2. Naked-eye 3D-TCL movie and television solution Naked-eye 3D-TCL movie and television solution provides a method that can convert ordinary 3D signal sources (2 viewpoints or single viewpoints) into naked-eye 3D signals in real time. Viewers can watch 3D movies and television without wearing professional 3D glasses or special 8-viewpoint 3D film sources. This scheme not only solves the problem of lack of 3D film sources, but also provides high-quality 3D video, which is of substantial significance to the application and promotion of naked-eye 3D TV in high-end private 3D cinemas in bars, 3D cinemas, clubs and even public entertainment places.
3. Naked-eye 3D-TCL game system solution TCL naked-eye 3D game system provides naked-eye stereoscopic display solution, which can support regular 3D modeling games above Direct X 9.0.
