Five, Hisense LED46XT39G3D 3D principle of analysis
3D is an abbreviation for English Three-Dimensional, which is a three-dimensional image. Due to the difference in the angles of the objects observed by both eyes, it can be discerned that the objects form a stereoscopic vision far and near, and 3D TV uses this principle to separate the images seen by the left and right eyes, and finally synthesize the separated images in the human brain. Form a three-dimensional image at your fingertips.
Hisense LED46XT39G3D 3D principle of analysis
There are many ways to achieve 3D video viewing, which can be mainly divided into naked-eye type and glasses type. Among them, the naked-eye raster display method and holographic display method are difficult to achieve, and it is expensive and difficult 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, brightness is relatively low; time division method is also known as active shutter 3D technology, widely used, excellent results, the disadvantage is that glasses are expensive and some of the screen will A sense of flicker. Hisense 46XT39G3D uses mainstream active shutter 3D technology.
Hisense LED46XT39G3D 3D principle of analysis
In the 3D display solution, Hisense XT39G3D series uses a 3D video chip, true +240Hz LED, active shutter 3D glasses program.

Six, Hisense LED46XT39G3D 3D screen effect
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. The following is the 3D screen effect of "Alice in Wonderland" played on a 3D Blu-ray player.

The use of 3D technology in the LCD TV platform will inevitably create a problem, that is, the problem of viewing angle. The angle of viewing here is not the viewing angle, but the angle between the horizontal position of the 3D glasses and the TV. In a word, the problem is whether you can wear 3D glasses and watch TV on your side. Judging from the actual playback effect, when the 46XT39G3D is wearing 3D eyes, the brightness of the screen through the glasses will be continuously attenuated as the viewing angle increases. When the angle between the glasses and the screen reaches 90°, the screen will be completely blocked.
