The Evolution of Three Dimensional (3D) Imagery
The 3D effect is achieved using a parallax barrier technique to separate light signals. Light from the LCD is divided so that different patterns reach the viewer's left and right eyes. The direction in which light leaves the display is controlled so that the left and right eyes see different images. When centered in front of the display, each eye receives the correct visual information for the brain to process. This makes it possible for the image on the screen to appear in three dimensions without the user having to wear special goggles.
"Sharp's TFT 3D LCD technology works on the principle of displaying left and right eye views that are separated so that the left eye sees only the left eye image, and the right eye sees only the right eye image," explained Ian Matthew, 3D Solutions Business Development Manager at Sharp Systems of America. "Since these images have perspective and are offset in the same
way that the human eye normally sees the two images, the brain naturally interprets the image disparity and creates a 'sense-of-depth' effect. The result is a 3D, 'out-of-screen' display that provides users with a visual experience previously unattainable without polarized or liquid crystal shuttering lenses."
