Why is the stereo glasses a blue one red
Finally, a liquid crystal glasses only temporarily on the computer in the use of glasses to a high frequency of the left and right lenses are black, the picture with the glasses left or right frequency synchronous display screen, allowing the eye to see a different picture, but the drawback is obvious, the picture is kept flashing, so this flicker frequency is very high (more than 120HZ) can not feel the flicker, but now the LCD frequency is only 60, the display can have to buy special effect. Also the stereo effect temporarily only part of the game, the movie is to find such sources
The relatively high cost of multi polarized 3D glasses, is a pair of left and right eye polarizing glasses angle different, cost about 20 or so, play requires two complete synchronization and projector, projector with polarizing filters, two polarizing filters with perspective glasses left and right eye respectively. The light polarizing characteristics coincide is the angle through different angles and light will be filtered out, two polarizing projection equipment from different angles with glasses to achieve around the eyes to see a different image to achieve the stereo effect, recent movies are basically using this method, compared with the red and blue color is no problem, the effect will be good many, but limited to the cost of the equipment is too high, the home is very difficult to achieve
Red and blue three-dimensional glasses is only the lowest cost of three-dimensional glasses in one of the worst, as well as polarization, LCD and other types ofPrinciple of all stereo glasses are a left eye, to see a different picture, with poor visual three-dimensional images in the mind are different. The synthesis of various types of glasses and the corresponding source playback device:Red and blue only cost a few cents glasses and ordinary playback device can, the movie is two a partial red a bluish overlapping picture, because red blue are complementary colors, the red lenses look will filter out the blue screen, the same blue lens will filter out red screen, so as to realize a different picture about eye stereoscopic effect, the cost is very low but relatively poor effect, especially in the color does not reflect the true colors of things
