Mitsubishi, Samsung, Panasonic, Sony, and JVC will all be showing off 3-D products at CES.

Companies including RealD and Dolby have developed technology that provides the correct visual information to the left and right eye using polarizing lenses that filter two differently polarized versions of video footage to their respective eyes.

Philips has offered a display that bypassing the glasses altogether. Its 3-D television plays specially created videos that contain two frames for each scene, one with color information, and the other with grayscale depth information. Lenses on the screen itself project these slightly different images to the left and right eyes, creating the illusion of depth.
