Analysis of the principle of transparent screen technology

As for 3D TV, many friends may only be limited to the understanding of the role of the screen, transparent screen display principle, many friends are not very understanding. To this end, in the 3D TV to enter the consumer family together, let us first come to understand the relevant information about 3D TV skills.

The so-called 3D TV is a special precision cylindrical lens screen on the LCD panel, and the 3D video image processed by the encoding is independently sent into the left and right eyes of the person, so that the user can experience the stereoscopic feeling of the naked eye without relying on the stereo glasses. Compatible with 2D graphics.

Now 3D TV display skills can be divided into two types of glasses and naked eyes. The naked eye 3D is now used primarily for shared business occasions and will be applied to portable devices such as mobile phones in the future. In the field of household consumption, whether it is a monitor, a projector or a TV, it is now necessary to cooperate with 3D glasses.

With regard to the glasses-type 3D skills, we are able to subdivide three primary types: color difference, polarized and active shutter, which is commonly referred to as color separation, light division and time division.

Chromatic 3D skills

Color difference 3D skills, English is Anaglyphic 3D, cooperative use of passive red-blue (perhaps red-green, red-green) filter color 3D glasses. This kind of skill has the longest history, the imaging principle is simple, the cost is low, and the glasses cost is only a few dollars, but the 3D picture is also the worst. The color difference type 3D first separates the spectral information by the rotating filter whee, and uses the filters of different colors to filter the picture, so that two pictures can be produced in one picture, and each picture of the person sees different pictures. This method is easy to make the color of the screen margin.

Polarized 3D skills

Polarized 3D skills are also called polarized 3D skills. English is PolarizaTIon 3D. Transparent screens use passive polarized glasses. The effect of polarized 3D skills is better than that of color difference, and the cost of glasses is not too high. Nowadays, more cinemas use this type of skills, but the brightness of display devices is higher. On LCD TVs, the application of polarized 3D skills requires the TV to have a refresh rate of 240 Hz or higher.
