First, TCL P7200 first evaluation after the test
P7200 is different from TCL's flagship model V8200, and does not carry super smart features. Instead, it uses the ordinary mitv 2.0 operation menu. However, the P7200 still has two kinds of wireless and wired network connection methods, and has an intelligent application store, you can use Sina Weibo, Baidu maps and other types of applications, so its smart features still have a good degree of practicality. In 3D, TCL does not use flash 3D technology like other domestic manufacturers. Instead, it uses active shutter 3D technology to display true full HD 3D images.

Five, TCL P7200 3D principle analysis
At present, there are many ways to realize 3D video viewing, which can be mainly classified into naked-eye type and glasses type, among which the naked-eye type raster display method and holographic display method are difficult to achieve, and it is expensive and hard to popularize. Spectacle type is divided into color separation method, light division method, time division method and other technologies, color separation method is the earliest and cheapest 3D technology, but easy to cause color cast, 3D effect is also the worst; light division method that is high school textbook introduction The polarizing 3D technology is better than the color separation method, but the screen is difficult to achieve full HD resolution, brightness is relatively low; time division method is also known as active shutter 3D technology, most current first-line TV manufacturers use this technology, have no effect The advantage of the picture effect is that the glasses are heavy and expensive and some of the pictures have a flickering effect.
TCL P7200 3D principle analysis
TCL P7200 uses the active shutter 3D technology, the principle is this: the screen will be displayed to the left eye to see the screen, then the glasses will cover your right eye at the same time, a bit like pirates wear goggles. Then, the screen will quickly switch to the right eye. At this time, the glasses will turn to cover your left eye and make sure that the picture you see is correct. This process alternated very quickly, reaching 120 times per second, so it was impossible for the human eye to see this shift.
TCL P7200 3D principle analysis
TCL P7200 with the glasses in appearance is relatively simple, the material is also more general polished plastic, but the temples with a plastic material, easy to wear.
TCL P7200 3D Glasses Details
Relative to the polarized 3D technology, most of the current joint-venture first-line brands still use active-shutter 3D technology, and TCL is also one of the few domestic manufacturers currently adopting this technology. This technology can guarantee the sharpness of the image while realizing the 3D picture. >>
Six, TCL P7200 3D screen effect
The TCL P7200 uses the active shutter 3D technology commonly used in joint venture brands. How does it perform? Xiao Bian will now perform 2D and 3D screen captures of similar clips in playback to compare the differences between 2D and 3D screens, especially the two major differences between depth of field and brightness.

TCL P7200 3D effect test
The 3D image played this time is played by Sony Blu-ray player S470. Because the 3D image is formed by the difference in the distance between the left and right eyes, the blurry ghost image will only be seen when the 3D image is viewed without glasses. The 3D degree created by different scenes is also different, so the ghost image may not be correct. Will be very obvious

Seven, TCL P7200 gray scale comparison test
Since the screen shot has undergone the necessary software processing and is affected by the actual effect of the netizens' display, the screen displayed on the screen will eventually differ from the actual effect of the TV. Therefore, the actual effect is based on the author's text description. The author uses Hi-Definition Reference Disc to test the disc, using the Sony S470 as Blu-ray player. The camera was shot with a Canon 30D and the lens was a Canon EF-S 17-85mm f/4-5.6.
The first test was a 15-gradient grayscale test. From the actual screen, the P7200 LCD TV performed fairly well. It was easy to distinguish each gray level, and the 0, 1, 14 and 15 gray levels were more obvious. . It should be noted that when the natural light technology is turned on, the screen brightness is slightly higher than when the natural light technology is turned off, and the user can select whether to turn on or off according to his own needs.

In black and white contrast, the separation of the clothes of the black woman and the background is more obvious, and at the same time, there is also a good reduction effect on the details of the white highlights.
Color test
After changing the position, the edge of the black woman is still relatively sharp, and the texture of the silk clothes is also relatively good, and the red color is not too bright.
Color test
In the girl's image performance, P7200 restores the skin tone of the girls to be somewhat yellow, but the restoration of the red clothes is not too bright, and the restoration of the hair details is also relatively clear.
Color test
From the gray-scale contrast test, it can be seen that the P7200 performs better on the details of the dark part, but it has noise problems when displaying the dark part of the image, which may be a problem of the internal image processing circuit. In color restoration, the P7200 is more vivid and saturated with color reproduction, and it is also somewhat warm. >>
Nine, TCL P7200 dynamic screen test
In this part of the test, you need to pay attention to what the netizens are paying attention to is the car behind the windows of the fast-moving train and the body plates of the car. The author used the same ISO and aperture during the shooting process. The parameters are ISO-400 and F4.5. The exposure time is 1/100 seconds. TCL P7200 uses 120Hz speed processing technology, let us look at how it performs on the dynamic screen.
Judging from the effect of the moving train, the edge of the house through the train window display is relatively clear, which shows that it is excellent in the display of dynamic images.
