To understand whether you need 3D glasses for 3D TV, it’s essential to know how the technology works. There are several types of 3D TV technologies available in the market, including:
Stereoscopic 3D
Stereoscopic 3D is the most common type of 3D technology used in TVs. It works by displaying two separate images, one for each eye, which are then combined by the brain to create a 3D effect. This technology requires the use of 3D glasses to separate the images and direct them to the correct eye.
Autostereoscopic 3D
Autostereoscopic 3D, on the other hand, does not require the use of 3D glasses. This technology uses a special screen that directs the images to the viewer’s eyes, creating a 3D effect without the need for glasses. However, this technology is still in its infancy, and the content available for autostereoscopic 3D TVs is limited.
Active Shutter 3D
Active shutter 3D is another type of 3D technology that requires the use of special glasses. These glasses have shutters that open and close in sync with the TV’s refresh rate, directing the images to the correct eye. Active shutter 3D provides a more immersive experience than stereoscopic 3D, but it can be more expensive.
The Role Of 3D Glasses
3D glasses play a crucial role in stereoscopic 3D and active shutter 3D technologies. They help to separate the images and direct them to the correct eye, creating a 3D effect. There are several types of 3D glasses available, including:
Polarized 3D Glasses
Polarized 3D glasses use polarized filters to separate the images. They are relatively inexpensive and provide a good 3D experience. However, they can be prone to ghosting, which is a phenomenon where the images appear to overlap.
Active Shutter 3D Glasses
Active shutter 3D glasses, as mentioned earlier, have shutters that open and close in sync with the TV’s refresh rate. They provide a more immersive experience than polarized 3D glasses but can be more expensive.
