For 3 d TV may be a lot of friends only confined to the understanding of the effect on the image, the display principle, a lot of friends is not very understanding. Therefore, in 3 d TV gradually into the consumer family at the same time, might as well let's together to learn about the information of 3 d TV technology.
A 3 d TV, is on the LCD panel with special JingBing precision cylindrical, encoded processing of 3 d video images into independent people around eyes, open hole without using 3 d glasses to make user experience stereo feeling, also can be compatible with 2 d images.
The current 3 d TV display technology can be divided into two major categories of glasses and the naked eye. Glasses-free 3 d is mainly used for public business occasions at present, the future will also apply to mobile phones and other portable devices. And in the field of household consumption, no monitor, projector, or television, are now needs to be used with 3 d glasses.
For the glasses 3 d technology, we can segment out the three main types: the color type, polarization and active shutter, namely say usually color points, points of light and time division method.
The color difference type 3 d technology
Color difference type 3 d technology, English for Anaglyphic3D, cooperate to use passive red and blue (or red and green, red and green) screen 3 d glasses. This technology's oldest, simple imaging principle, make the cost cheap, glasses cost for only a few dollars, but 3 d effect is the worst. Color difference type of 3 d first by rotation filter wheel to separate spectral information, using different color filter screen filter, so that you can produce an image, two images of each eye to see different images. This method is easy to make the picture edge produces color.
Polarized 3 d technology
Polarized 3 d technology is also called the polarimetric 3 d technology, English for Polarization3D, cooperate to use passive polarized glasses. Polarization type 3 d image effect is better than the color type, and glasses cost is not high, the more the cinema is the technique, but higher requirements on the brightness of the display device. Application in liquid crystal TV, polarized light type 3 d technology for TV more than 240 hz refresh rate.
Active shutter 3 d technology
Active shutter 3 d technology, English for ActiveShutter3D, used with active shutter 3 d glasses. This kind of 3 d technology most widely used on television and projector, more resources, and the image effect is good, many vendors acclaimed and adoption, but its matching 3 d glasses price is higher. At present, including LG, samsung, panasonic, skyworth brand launch 3 d TV, active shutter 3 d technology is adopted.
