Five, LG 47LW6500-CA does not flash 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, also known as active shutter 3D technology, has the advantage of not affecting the picture effect, the disadvantage is that the glasses are heavy And the price is expensive and some of the screen will have a flicker.
3D image imaging principle
Different from traditional shutter 3D TVs, LW6500's "Flashless Full HD 3D" technology utilizes high-precision panel film technology. Through the principle of polarized light, the left eye and the right eye each see the best image. It not only makes the 3D image quality clearer, brighter and more realistic, but also avoids the problem of flickering and ghosting in 3D images.
Polarized 3D left and right screen enters left and right eyes at the same time
The 3D glasses that are compatible with the LW6500 need no power supply and do not need a signal receiving system. Therefore, they are lighter and more comfortable to wear, and do not give the user a negative feeling. And, its price is also closer to the public, so that we can easily have more 3D glasses, you can share the wonderful 3D vision with your family.
LW6500 3D glasses do not need power
The LG LW6500 adopts the polarized 3D principle, which has the characteristics of no flicker, no ghosting, etc. In addition, it also gives the user a more comfortable viewing experience and can see the 3D picture even when lying on the sofa. The LW6500's glasses are cheap, light weight, and comfortable to wear. >>
Six, LG 47LW6500-CA does not flash 3D screen effect
One of the great features of the LG 47LW6500-CA is "do not flash Full HD 3D". How does the 3D effect behave in the end? Below we look at the screen shots. In order to allow users to experience the difference between 3D images and 2D images more intuitively, the authors used the naked eye and the 3D glasses to perform screen captures. In the naked eye, we see 3D images with ghost images. The picture taken through the 3D glasses is a 2D image. By comparing the two, we can still find many differences and the general effect of 3D images.
LG 47LW6500 "do not flash full HD 3D" effect?
The first is depth of field and crosstalk (Crosstalk). From the following 3D screens and 2D images captured through glasses, the depth of field of the LW6500 is still relatively clear, and the crosstalk is very good, and crosstalk is hardly noticeable. phenomenon.

The last is the screen color, according to the author's actual experience, LG 47LW6500's color performance is relatively bright and full, but is limited to LCD TV display principle, to improve the brightness of the viewing screen, the screen style will be slightly white biased effect.

In addition, it is necessary to mention that the LG 47LW6500 supports 2D to 3D functions. Even ordinary 2D video can be converted into 3D images in real time, which breaks through the limitation that only 3D sources can watch 3D TVs. Although the stereoscopic effect of the converted 3D image is inferior to native 3D, this function is still quite practical, which greatly reduces the problems caused by the shortage of 3D film sources.

Compared with the traditional 3D TVs that must be “sitting side by side†to watch, the LW6500's “Not Flash Full HD 3D†also gives users a more free viewing experience. Users can choose to watch TV in various comfortable postures. You can get clear 3D images from the LW6500 even when lying down.
3D glasses rotate about 45° counterclockwise (simulating left to watch)
3D glasses rotate clockwise by about 75° (simulating to the right)
In terms of angle, the advantages of the LW6500 are very obvious. The brightness of the 3D screen will not be attenuated with the change of the angle. The following will be experienced through a dynamic picture of glasses from 0° to 90°.
LG LW6500's 3D screen brightness does not dim due to viewing angle changes
Due to the polarized 3D principle, the 3D picture displayed by the LW6500 has almost no ghosting and crosstalk. After wearing glasses, it still has a higher picture brightness, and the angle advantage is even more pronounced. View 3D images from an angle. >>
Seven, LG 47LW6500-CA grayscale, black and white contrast 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 used a Hi-Definition Reference Disc to test the disc. The digital camera used was a Canon 50D. The lens used a Canon EF-S 18-200mm f/3.5-5.6 IS.
The first test was a 15-gradient grayscale test. From the actual picture, the LG 47LW6500-CA LCD TV performed satisfactorily, and it was easy to distinguish each gray level difference between 0 and 1, 14 and 15 gray levels. Are very obvious.
