What are the different types of 3D TV glasses?

with three -dimensional (3D) TVs on the market is looking for many consumers 3D TV glasses that allow them to view movies and television shows created for this technology. Many people know about paper glasses with red and blue lenses because they are cheap and have been for years. However, there are new ways to display 3D images because newer technologies have allowed different types of 3D glasses. One example is the polarized type of glasses, which falls into the passive category of glasses as an updated version of the species with red and blue lenses. Active glasses are also popular, especially among those who long for the ability to see colors exactly when watching 3D television.

The least expensive type of 3D TV glasses is a passive type. The most common example is the poor cardboard glasses with one red lens and one blue lens, which many people used during childhood. This product is referred to as anaglyphic glasses with 3D TVs would not work because the colors would not be precisely displayed. With this technology, two different projectors are used on the screen to place a red image and a blue image. When viewers use anaglyphic glasses, the blue lens can filter a red image, while the red lens filters the blue image and creates an optical effect that causes images on the screen.

Another example of passive 3D television glasses is a polarized species that generally replaced the type of anaglyph, so the colors are more accurate, although the idea is the same. As with anaglyphic glasses, two projectors, each with a different polarization, place a picture on the TV screen. Each polarized lens filters the image, allowing each eye to see a different image, resulting in the look that the image is 3D. Linear passive glasses require viewers to look directly forward at The Screen to display 3D images as the head move from one side to the other can spoilIT optical effect. For this reason, circular passive glasses are more popular because viewers can still see a 3D picture when they extinguish their head.

Active 3D TV glasses are usually more expensive, but are often preferred over the passive type because this technology is more compatible with modern 3D TVs. In most cases, liquid crystal lenses (LCD) alternate between opening and closing at different times, so each eye sees a different image on the screen, resulting in an optical effect. These glasses are usually called active 3D TV glasses and their disadvantages include a higher price than passive glasses and energy source. In addition, each eye sees the screen at different times, because each lens opens and closes, which means it is basically reduced to half, which slightly reduces the quality of the image. For many people, the ability to accurately color in 3D images without much eye tension is worth any disadvantages, so these 3D TV glasses are popular.
