How much is the naked eye 3d TV?
The naked eye 3D, as the name suggests, is directly naked to the eye, without the aid of glasses and other auxiliary tools can produce 3D vision, which is undoubtedly a breakthrough in the era of 3D trending, combining naked eye 3D technology and LED super TV is even more icing on the cake.
Because the LED super TV is directly displayed on the LED panel, it is different from the traditional LED backlight TV. It not only consumes less energy, but also is not limited by the process. It can be multiplied in size, increasing the viewing angle and length. Up to 3 meters of appearance and 34 viewpoints ensure a 170 degree horizontal viewing angle, avoiding the vertigo discomfort caused by the angle of view.
Mainstream naked eye TV technologyFrom the display principle, the current naked-eye 3D technology is mainly divided into two types: raster type and prism type. The grating type 3D technology has advantages in cost and can be manufactured on the existing liquid crystal panel production line, but the screen brightness is low and the resolution is lowered. The prismatic 3D technology does not reduce the screen brightness, but the cost is high and cannot be produced on the existing LCD panel production line.
Experts pointed out that the current naked-eye 3D TV, long time to watch is easy to cause fatigue or even discomfort, this is the biggest technical difficulty that needs to be overcome. According to Wang Yongtian, the display mode of 3D TV is different from that of the usual eye. When we look at a three-dimensional object, the eyes concentrate the light at one position at the same time, and the focus is also at this position.
But for the current 3D TV and naked-eye 3D TV, we have to see the image, the eyes should be focused on the screen, but the stereo image displayed on the screen is either out of the screen or behind the screen, so the eyes gather. The distance is also before or after the screen, which causes the two distances to be inconsistent. The eyes will feel uncomfortable after a long time, and even dizziness and nausea may occur.
In addition, another fatal flaw in the naked-eye 3D TV is the viewing angle problem. Generally, the viewing angle is only two to three, and the image blurring appears at a slight angle. If a family of four or five people are watching TV, there will be many viewpoints. So with so many different viewpoints, there are big problems with naked-eye 3D TV.
1. Light Barrier-Light Barrier 3D technology is also called parallax barrier or parallax barrier technology. Its principle is similar to that of polarized 3D. It has been successfully researched by Sharp's European laboratory engineers for more than ten years. The light barrier type 3D product is compatible with the existing LCD liquid crystal process, so it is advantageous in terms of mass production and cost, but the image resolution and brightness of the product using this technology will decrease. The light barrier type 3D technology is realized by using a switch liquid crystal panel, a polarizing film and a polymer liquid crystal layer, and using the liquid crystal layer and the polarizing film to produce a series of vertical stripes with a direction of 90°. These stripes are several tens of micrometers wide, and their light forms a vertical thin-gate pattern called a "parallax barrier." The technology utilizes the parallax barrier disposed between the backlight module and the LCD panel. In the stereoscopic display mode, when the image that should be seen by the left eye is displayed on the liquid crystal screen, the opaque stripes will block the right eye; similarly, When the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block the left eye, and the viewer can see the 3D image by separating the visible images of the left and right eyes.
Advantages: Compatible with existing LCD liquid crystal processes, so it is more advantageous in terms of mass production and cost
Disadvantages: the brightness of the picture is low, and the resolution is inversely proportional to the increase in the video output at the same time.
2, lenticular lens - lenticular lens technology is also known as lenticular lens or micro cylindrical lens 3D technology, its biggest advantage is that its brightness will not be affected. The principle of the lenticular lens 3D technology is to add a lenticular lens to the front of the liquid crystal display so that the image plane of the liquid crystal panel is located on the focal plane of the lens, so that the pixels of the image under each cylindrical lens are divided into several sub-pixels. This allows the lens to project each sub-pixel in a different direction. Then the eyes look at the display from different angles and see different sub-pixels. However, the gap between pixels is also amplified, so the sub-pixels cannot be simply superimposed. Let the cylindrical lens be parallel to the pixel column, but at an angle. This allows each set of sub-pixels to be repeatedly projected into the viewport instead of just projecting a set of disparity images. The reason why its brightness is not affected is because the lenticular lens does not block the backlight, so the brightness of the picture can be well protected. However, since its basic principle of 3D display is still similar to the parallax barrier technology, resolution is still a difficult problem to solve.
Advantages: 3D technology shows better results and brightness is not affected
Disadvantages: Related manufacturing is not compatible with existing LCD liquid crystal processes, requiring investment in new equipment and production lines
3, pointing to the light source - the main energy input to the 3D technology of the light source is 3M company, pointing to the light source 3D technology with two sets of LEDs, with fast response LCD panel and driving method, let 3D content enter the viewer's left and right by sorting The eye interchange image produces parallax, which in turn makes the 3D 3D effect visible. Not long ago, 3M has just demonstrated its successful 3D optical film. The interview of this product enables real 3D stereoscopic images to be displayed on mobile phones, game consoles and other handheld devices without wearing 3D glasses. Mobile-based communication and interaction.
Advantages: resolution, light transmittance can be guaranteed, will not affect the existing design architecture, 3D display is excellent
Disadvantages: technology is still developing, products are not mature
The naked eye 3D is still a high-tech, not popularized and mass-produced. The result of my search is that only Toshiba has a naked-eye 3D LCD TV, 60,999 yuan. I don't think 3D TV is of much use. At most, the Olympic Games, the Spring Festival Gala and other large-scale programs and movies will be shot in 3D. A lot of ordinary variety entertainments will not be made into 3D. We usually watch TV. Can't always look with 3D eyes, too tired.
1, people are tired
The current naked-eye 3D TV, it is easy to cause fatigue or even discomfort when watching for a long time. This is the biggest technical difficulty that needs to be overcome.
2, the viewing angle is small
Another fatal flaw in naked-eye 3D TV is the viewing angle problem. Generally, the viewing angle is only two to three. If you look at it, the image will appear blurred. "If a family of four or five people are watching TV, there will be many viewpoints. So with so many different viewpoints, there is a big problem with naked-eye 3D TV."
3, the lack of source is scarce
At present, the problem of insufficient 3D source is still unresolved. Domestic TV stations have few 3D channels and programs are very limited. Compared to ordinary 3D, the source content of the naked eye 3D is more complicated. Moreover, the naked eye 3D depends largely on the production of the content, and the presentation of the source determines whether the image is displayed on the TV as 2D, 3D or naked eye 3D.
