Currently, there are many TV models on the market of 3D TVs, and if you have to choose, users will surely face many difficulties, they do not understand the 3D technology applied on those TV models. Which technology will be more suitable. So the following article, WebTech360 will send you information about 3D technology that is widely used on today's TVs.

What is 3D TV?
In the simplest sense, 3D TV is a television line with display capabilities that help users view 3D images. In principle, the work of these TV models is that the screen will display 2 frames at the same time, 1 frame for the left eye and the other frame for the right eye, and with the combination of specialized glasses. Viewers' vision will be deceived by 2 frames and those images will be merged to form one image in 3-dimensional space. Currently there is some information about the development of new generation TVs with the ability to watch 3D content without using glasses, but the price will be very high and has not yet been introduced in the market. Vietnamese school.

3D display technology
Active 3D technology
Active 3D technology uses shutter glasses or Shutter Glass for viewing. This shutter glass is a battery-powered device for operation and uses a wireless connection to synchronize the display image with the TV. For this active 3D technology, you must use glasses to feel it because the glasses are a device used to rotate the frame on the TV and display separately 2 content for the left eye and right eye.
Shutter Glass
The advantage of this active technology is that the display quality of 3D images can be up to Full HD , for sharp, smooth image quality that brings the most realistic feeling to the viewer.
Good display quality
The biggest downside of this technology is the Shutter Glass, when wearing this device we will feel quite heavy, and the viewing angle is not very good, the image is only really beautiful and sharp when we sit. directly to the TV. In addition, this glasses only works with TV models of the same origin, for example Panasonic glasses can only be used on Panasonic TVs and absolutely not work for other brands.
Viewing angles are not good
Passive 3D technology
Passive 3D technology is applied to TV models that are coated with FPR film on the screen by the manufacturer, with the use of creating different images on the left and right eyes. For passive 3D technology, the glasses used are polarizing glasses, those used in movie theaters. The use of this glasses is to divide the displayed image into two eyes, then through the glass, the images are combined to create a 3-dimensional space.
Passive 3D technology
The advantage of this passive 3D technology is that the glasses, its weight is much lighter than the Shutter Glass, in addition the viewing angle is also significantly expanded, allowing the viewer to freely choose the position. At the same time, the brightness from the glasses is also better, reducing eye strain when viewing for a long time. And without using the battery, this product is good for the health of the user when it does not emit a connection signal.
Glass is extremely light in weight
The downside of this technology is the display image quality, it depends too much on the film glued to the front of the screen, so the resolution is greatly reduced compared to active 3D technology. its maximum visibility is just HD.
The resolution is not good
