Did you notice? Most of the large films that have just been released now support 3D effects, such as the recently acclaimed "Tianjin Lion". The shocking audio-visual effect is fascinating, but it is very inconvenient to watch in the theater. It is better to watch the game directly at home. All you have to do is buy a 3D TV. But with 3D TV brands and types, how can I buy a satisfactory 3D LCD TV? Look at the following content and you will know.
Which kind of 3D TV should I buy?
3D TV can be divided into active shutter 3D, polarized 3D and naked-eye 3D TV. Which type is better?
1, active shutter 3D technology
Active shutter 3D technology is the earliest 3D technology. The main imaging principle of this technology is based on the refresh of the affected frequency by the human eye. By increasing the refresh rate of the picture, the left and right eyes can see two different fast-switching images and thereby generate a simulated stereo image in the brain.
The current active shutter type 3D TV has the advantage that it has few residual images, and as long as the update frequency can meet the requirements, 1080P full HD 3D images can be realized.
2, passive polarization 3D technology
Polarized 3D technology uses the principle of "vibration direction" of light to decompose the original image. By adding a polarizing plate to the display screen, two different polarization directions can be transmitted to the viewer. When the image passes through the polarized glasses, Since each lens of the polarized glasses can only receive one picture of the polarization direction, the left and right eyes of the person will receive two sets of pictures, and finally the stereoscopic image will be synthesized through the brain.
The polarized 3D TV can effectively improve the screen flashing phenomenon of the 3D picture, and the user does not have any physical discomfort because of the lightness of the glasses.
3, naked eye 3D technology
The naked eye 3D technology can be divided into three types: light barrier type, lenticular lens technology and pointing light source. Since the angle of the human eye is slightly different, it is possible to distinguish the object from the distance and produce a stereoscopic vision.
As far as the current market is concerned, the naked-eye 3D TVs that are really used for home use are still relatively few. The vast majority of naked-eye 3D TVs are used for commercial or military use.
How can I find a 3D TV that I like?
1. Is the 3D TV selected LED, LCD or plasma?
The traditional LCD TV adopts CCFL as the backlight source, which has obvious price advantage, and the color of the 3D TV is sharper and brighter in display effect. Plasma TVs have a relatively high refresh rate, and the performance of the dynamic picture is obvious, and the display size is relatively large. The 3D plasma TV performs best in the reduction of cinema effects.
LED TVs are LCD TVs that use LEDs as backlights. It has become the standard for 3D LCD TVs. The new generation of LED technology - FULL LED backlight technology combines the advantages of side-entry and direct-lit LED, evenly distribute the LED backlight on the back of the screen, adjust the amount of illumination of each LED according to the picture, let the screen brightness More even, more comfortable eyes, and half the power.
Therefore, in summary, Xiao Bian is still recommending LED TVs that dominate the market.
3. How big is the size of 3D TV?
It is of course more shocking to see the large size of the 3D TV. Only in this way can you experience the 3D effect better and fully integrate into the immersive three-dimensional world. This is mainly because, on the one hand, the large screen can present more details of the picture; on the other hand, when consumers wear 3D glasses to watch, they can concentrate on the TV screen without being affected by the extra perspective. .
At the same time, Xiao Bian reminds consumers that the size of the specific purchase should be determined according to the size of the individual housing space. The size of the space mentioned here mainly refers to the best visible distance.
3, 3D TV refresh rate is high
The refresh rate is an important indicator to determine the quality of the TV picture, especially the dynamic picture. The higher the refresh rate, the more stable the image and the less damage to the eyes. At present, the mainstream 3D TVs need to wear 3D glasses, and the left and right eyes receive only half of the original frame frames per second, which puts higher requirements on the refresh rate.
The above content is the method and precautions that I have summed up to purchase 3D LCD TV. I hope that I can provide some help for everyone's purchase after reading it.
