Active 3D is a technology used in 3D displays that enhances the viewing experience by providing separate images to each eye. This is typically achieved using special glasses that synchronize with the display, allowing viewers to perceive depth and dimension in the content. Active 3D is commonly found in televisions, cinemas, and video games. The technology works by rapidly alternating the images shown to each eye, creating a stereoscopic effect. This method differs from passive 3D, which uses polarized glasses and a single image. Active 3D is known for delivering sharper images and better color quality, making it popular among enthusiasts of home theater systems.
