What is the principle of 3D smart TV 3D display

What is a 3D smart TV?
3D is in the early stage of shooting, imitating the human eye to view from two angles, and then through post-processing, making the left and right eyes produce visual difference, receive different pictures, and form a 3D stereo effect in the brain. A 3D smart TV is simply a smart TV with 3D capabilities.
What kinds of smart TV 3D?
Throughout the various brands of TV, the most used is nothing more than the shutter 3D and polarized 3D. In fact, there is also a kind of active 3D and passive 3D, in fact, there is a rare naked-eye 3D, perhaps no one is exposed.
3D display principle
When the human eye is watching the same object, there will be a gap of 65mm between the two eyes. Within a certain distance, there will be some visual difference between the two eyes.

Shutter 3D
The advantage of the shutter 3D is that the viewing angle is large, the picture is not blurred or overlapped due to deviation from the center point of the TV, and the overall brightness of the TV is not dimmed by turning on the 3D mode. The shutter 3D mainly realizes the 3D effect by increasing the refresh rate of the TV picture, and divides the image into two according to the frame, so as to achieve different continuous interlaced pictures by the left and right eyes, and the TV infrared emitter controls the left and right lenses of the glasses, and can receive the phase normally. Corresponding screen. The shutter 3D refresh rate should be above 120HZ to see a clear 3D effect.

2. Polarized 3D
Polarized 3D is an inexpensive 3D display mode, and is also positioned as a low-end 3D display mode, commonly known as passive 3D. The cost is low, and the contrast shutter 3D effectively improves the flicker phenomenon, and does not feel uncomfortable because of wearing for a long time. It is widely used in low-end and mid-range TVs, but there is an angle limitation, which also reduces the overall brightness of the TV. Polarized 3D uses the principle of "vibration direction" of light to process the original image, and then adds a polarizing plate to the display screen to obtain two different images, and with the polarized glasses, a stereoscopic 3D image is obtained.

Electronic Tools

The electric tool is a kind of small electric motor or electromagnet as the power. A small tool that drives the working head through a transmission mechanism. There are a wide variety of electric tools, complete functions, easy to carry, and simple to use. They have been widely used in various industries and have entered the family. Electric tools are divided into handheld and movable There are two types. Hand-held power tools are more flexible, convenient and widely used. Many varieties have become necessary tools for production and life. There are many brands of power tools. According to the functions and uses of power tools, they are divided into nine categories. . Mainly are the following nine categories:
1.
