3D TVs without glasses, also known as autostereoscopic displays, allow viewers to enjoy 3D content without the need for special eyewear. This technology works by creating images that trick the eyes into perceiving depth using techniques such as:

Parallax Barrier: A barrier is placed in front of the screen, allowing each eye to see a slightly different image, creating the illusion of depth.

Lenticular Lens: This technology uses a series of lenses that direct light differently to each eye, also creating a 3D effect.

OLED or LCD Screens: Some TVs use specific display technologies, like OLED, which can enhance the viewing experience by providing more vibrant colors and better contrast.

Brands like LG, Toshiba, and Samsung have explored glasses-free 3D TVs, but the popularity of these technologies has varied, with many brands focusing more on improvements in 2D image quality and streaming solutions. If you’re considering purchasing one, it's a good idea to check for availability and reviews of specific models.
