What is 3D TV?

Before learning about passive 3D technology, you need to know what 3D TV is. 3D technology is the technology that creates stereoscopic images from televisions. 3D TV is a type of TV capable of viewing 3D content, the working principle of 3D TV is that the screen will display 2 frames at the same time, one for the right eye and one for the left eye, and they overlap.

What is passive 3D?

Passive 3D technology is equipped on TVs that have a layer of FPR film on the outside of the screen, this film is used to create different images between the eyes.

Passive 3D glasses

Passive 3D glasses are polarized glasses (like cinema glasses). Passive 3D glasses filter the image in each eye, so the left eye only perceives half of the image and the right eye sees the other half. The advantage of passive 3D glasses compared to active 3D glasses is that the glasses are very light, do not use batteries and do not have electromagnetic waves that affect health.

Image quality

Passive 3D glasses used with TVs are compact in size with relatively cheap prices, users can easily equip passive 3D TVs at a moderate cost (passive glasses cost from 50 to more than 400 thousand VND). Images through the specialized glass are brighter, flicker-free and blur-free. Because the two eyes receive light at the same time, the passive 3D image is brighter, not discrete and does not create a sense of noise when wearing glasses. In addition, the viewing angle with passive TV is also higher than with active TV (viewing angle up to 178 degrees).

However, according to some studies, the image display quality of passive 3D televisions is somewhat “inferior” than active 3D (3D passive for HD images / active 3D for Full HD images) but factors No need to charge the battery, the cost of investing in glasses and TVs is relatively cheap, so passive 3D TVs are chosen by many consumers.

Some passive 3D TV models worth buying

Today, most TV brands Sony, Samsung, LG, Toshiba… all use passive 3D technology. Some of the most prominent passive TV models on the market today such as: LG 42LB650T LED Smart TV with Full HD resolution, 42-inch screen costing less than 15 million VND, or TCL L40E5700 degree LED TV model 4K resolution, 40-inch screen and also costs less than 15 million (The popular resolutions on TV today).
