Red red green blue 3D glasses, crystal shutter glasses and a polarizer which good?
Each has its own merits，The advantages of red and blue glasses: cheap, as long as the color display can see. Disadvantages: the color is not real, the image is not clear.Shutter glasses advantages: clarity, high energy to 1080P. Disadvantages: special monitors are required. There is a slight flicker when looking at the film. The glasses are expensive, and different display glasses are not commonPolarization glasses advantages: super cheap glasses, and very general, the picture can not feel flashing shortcomings: need special display, clarity is too low, only 540P
The electronic shutter is certainly better, because the stereo electronic shutter to real, but the equipment requirement is very high, the polarization of the cinema is the red and blue is not what equipment requirements, but the effect is less than the electronic shutter.
The shutter is good, the shutter does not damage the clarity, brightness contrast requirements of high, but now the LCD technology is not a problem. But it's a bit expensive. Red blue is the previous fake 3D, no mention of it.Polarized light is coated with polarizing film on the screen, so in theory the resolution of polarized 3D is halved.PolarizedThe image effect is slightly worse, the picture resolution is halved, the picture brightness is greatly reduced, it is difficult to realize the real full HD 3D image.High brightness requirements for display devices. Requires more than 240Hz refresh rate. For LED, the technology risk and cost will increase dramatically in order to upgrade the refresh rate to 480HZ.Matching 3D glasses more lightweight. The price is quite cheap. Even if the glasses have been worn by the audience, as long as the clip on the Polaroid glasses.More emphasis on convenience and utility. Picture stability is better, and the glasses can be more lightweight, comfort is slightly dominant.Active shutterImage effect is excellent, can maintain the original resolution of the screen, to achieve the true full HD 3D effect, will not cause the screen brightness reduction. This is particularly evident in the PDP.Requirements of the left and right eye to receive more than 60Hz in the frequency of the image, PDP itself because of the use of 60HZ sub field drive, regardless of 2D or 3D, sub field frequency unchanged. Have a natural advantage in technology.Shutter type 3D technology matching 3D glasses price is more expensive, inconvenient to carry. But does not include PDP panel resources and equipment, technology and other issues.Pay more attention to the quality of the performance of 3D realistic effect, wide viewing angle. PDP+3D+ active shutter has more advantages.
