Five, Toshiba 55X1000C 3D principle 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.
Toshiba 55X1000C 3D principle analysis
The Toshiba 55X1000C uses active-shutter 3D technology. The principle is this: The screen will show the picture to the left eye first. At this time, the glasses will cover your right eye simultaneously, which is a bit like a pirate's blindfold. 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.
Toshiba 55X1000C 3D principle analysis
Toshiba 55X1000C comes with 2 pairs of active shutter 3D glasses. The appearance color of the glasses is all black, and the overall design is wide.

Six, Toshiba 55X1000C 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 first is the effect of depth of field. The following are the 3D pictures and 2D pictures taken through the glasses. From the two different positions of the same object, such as the robot and the bridge, we can roughly feel the depth of field effect. The 3D picture of the Toshiba 55X1000C is quite real. .
