An Avatar, so 3D craze sweeping the globe. To equipment manufacturers, content providers see a new suction gold hot, so the audience never experienced the incomparable experience of audio-visual enjoyment, and the mad chase of a similar work. For a time, 3D became one of the world's most popular topics, and 3D TV, 3D as the future of the industry is recognized as the unwilling behind. China, too, are these, up to the policy decision-making down to the TV manufacturers, all visibly moved, but the domestic industry, the confusion 3D 3D TV's prospects also a blur, is described as smoke and mirrors.
to lead the following round of the comb 3D industry.
a 3D TV concept, development history and the mainstream
1, what is the 3D TV
3D (three-dimensional) is the three-dimensional graphics. Observation of objects in the eyes of people slightly different point of view, it can identify objects near and far, resulting in three-dimensional vision. TV is the three-dimensional images using this principle, the left and right eyes see images of separation, through the formation of the brain after a three-dimensional image View deeply.
2,3 D television history
3D TV origins can be traced back to early 1903, scientists discovered a to create three-dimensional When television appeared, people had begun to develop three-dimensional television, the traditional still images or movies for viewing three-dimensional image display method was applied to almost all three-dimensional television technology. Stereoscopic television technology is with the stereo vision technology and the development of television technology development.
in the early black and white TV era, the more successful of the three-dimensional television cameras from two television image and use two separate video channels transmitted to the two television sets, each TV screen on the placement of a polarizer, and then use polarized glasses to observe, so three-dimensional television system can get better stereo image. This dual-channel stereo TV polarizing as it is still recognized as a good quality three-dimensional television system.
20 century, 50's, color television technology into a practical stage near the Basic method is to install filters with two cameras front of the lens to shoot the same scene images on the screen in color television viewers see is two different colors of the image superimposed on each other with the crowd through the appropriate filter light microscope can be seen when the three-dimensional television images. This three-dimensional imaging technology
TV compatibility, in the three-dimensional television technology was all the rage. But the problem is also very clear, first of all to observe the TV images through the filters, color information loss is enormous. Followed by the color TV's own
2009 �� 12 months, directed by James Cameron ? a cost of $ 500,000,000 of the blockbuster movie release in the world, setting off a global 3D boom.
3, the current mainstream technology, 3D presentation and the advantages and disadvantages of
a global scale now exist a variety of 3D display technologies, including developed by 3M, the U.S. led the naked eye 3D display technology, developed by Japanese companies Polaroid-style 3D technology, and the current mainstream 3D glasses type display technology.
1) naked eye 3D display technology:
most naked-eye 3D technology under development, primarily in industrial commercial display market, so the mass of consumers exposure to very little. Technically, the naked-eye 3D can be divided into light barrier type (Barrier), cylindrical lens (Lenticular Lens) technology and the point light sources (Directional Backlight) three. Naked-eye is the biggest advantage of 3D technology out of the shackles of glasses, but the resolution, viewing angle and visual distance, there are still many deficiencies.
currently has a number of display manufacturers have launched a free professional to wear 3D glasses you can see three-dimensional picture of the display device, their biggest advantage is that people will be able to completely do not need to wear glasses to experience the immersive effect.
this technology generally known as differentiated picture of their reflection to the brain, people will have a three-dimensional. It also used the parallax principle of the human eye, by giving the viewer about two different images are sent to achieve the three-dimensional visual effect. Because viewers can not wear glasses, so these techniques are suitable for display in public places large display, easy to people watch.
inadequate: however, uncorrected shortcomings of 3D display technology is also very clear that people watching the screen, must be located within a certain three-dimensional images can be observed, if the location is too far away from the screen, or when the viewing angle is too large, 3D effect is not obvious. In addition, if a short distance from the screen, people will have significant dizziness and, therefore, the technology is not yet suitable for use in small-size display. In addition, this technique is relatively poor in terms of display.
