There are many kinds of 3D glasses, but which one is best? how's the price? Today, the author brings everyone to understand the classification of the next 3D glasses, and at the same time explain what kinds of 3D glasses are better and what the price is. Interested friends are worth paying attention to.
3D glasses classification
Shutter-type 3D glasses
The principle of liquid crystal shutter type 3D glasses is very simple. The liquid crystal shutter type 3D glasses have two black and white LCD lenses and a frame. When they are working, the two lenses alternate in black at a certain frequency to block the right and left glasses of the person. The glasses display device alternately displays the left and right eye images in accordance with the frequency of the glasses. The alternating frequency of the glasses is controlled by a display device, such as a computer display card, and a dedicated stereo player.
The advantages of Shutter 3D technology lie in the following aspects: 1. High image quality resolution, 2. Wide viewing angle, no damage to 3.2D image, 4. Good contrast in bright environment, and no ghosting in 5.3D image. Disadvantages: 1. The price of the product is too high, 2.3D glasses are heavy, not easy to wear for a long time, 3. The brightness is low, 4. The glasses need to be replaced, and the charging is complicated.
2, polarized 3D glasses
Polarized 3D glasses are currently classified into linear polarization and circular polarization. Linear polarized polarized 3D glasses are relatively simple, using XY two deflection directions, that is, through the two different deflection directions of the polarized lenses in the glasses, so that the two eyes can only see one of the vertical and horizontal images superimposed on the screen. In order to see the three-dimensional effect.
Circular polarization polarized 3D glasses is a new generation of 3D polarization technology. Glasses technology is much more complex than XY polarized thin plastic film. As its name suggests, its lens polarization is circular rotation, one to the left, one to the right Rotate so that images in two different directions are separated.
The advantages of the polarized 3D technology lie in two aspects: 1. The glasses are light, 2. There is no picture flicker phenomenon caused by the glasses (ie, a ghost phenomenon). Disadvantages: 1 can not achieve the screen in the horizontal, the screen clarity is reduced, the resolution is low, 2. The viewing angle is narrow, in general there is no 3D image after the 90 degree angle, 3, there is a viewing angle limit, 4 screen polarizing film Vulnerable, 5. Low technical content.
3, red and blue 3D glasses
The working principle of the red and blue 3D glasses is to adopt the passability of light in the corresponding colors and different colors to achieve the two eyes to see only one of the images. The advantage is that it is cheap, affordable, almost free from maintenance, and has good applicability; the disadvantages are insufficient light flux, dim images, image color variations, and the like. This is now almost slowly eliminated.

3D Glasses Buying Tips
1, according to the technology of 3D glasses to choose: currently on the market 3D glasses used by the technology generally does not flash, time-division and complementary color technology, which does not flash, time-division two technologies have not been widely used, Not only can the 3D videos that can be played are rare, but also the price is relatively expensive. Compared with these two technologies, the 3D glasses using the complementary color technology are more suitable for the needs of mass consumers. Not only are the technologies mature, but also the 3D stereoscopic effects are good. The important thing is that this technology is the most popular. Most 3D movies on the Internet support this kind of glasses.
2, according to the lens material to choose: The quality of the lens has a direct impact on the quality of the viewing of the film, good 3D glasses lenses are generally made of high-quality 3D optical materials, stereoscopic effect when watching the movie, the image is clear; eyes Is not easy to produce fatigue, and inexpensive 3D glasses are often used ordinary resin lenses, stereoscopic effect is poor, the image is blurred, look for a long time there will be dizziness feeling;
3, according to the color of the lens to choose: Above we introduced the complementary color of 3D glasses is currently the most popular, the principle is that the two different views of the image shot in two different colors printed in the same sub-screen, so Each pair of 3D glasses has two colors. At present, 3D glasses with red and blue colors support the most videos, followed by green red and purple brown. Everyone should use red and blue glasses as the first choice if you want to watch more. 3D videos can be purchased together with other colors when selected;
4, according to the design of the frame to choose: due to the large number of viewers wearing glasses in life, which means that this part of the audience if you want to watch 3D movies you need to wear two glasses, generally good 3D glasses manufacturers have been in production Taking into account this issue, it will be designed in the 3D glasses frame to support the nesting of ordinary glasses, when viewing ordinary glasses nested in the 3D glasses to watch, very convenient.
5, according to the brand of 3D glasses to choose. The reputation of a branded product often represents the quality of a product, and the focus is on branding of 3D glasses. The practice of consumers pursuing a branded product is a certain truth. Consumers can consider more products with good reputation when they purchase.
