3D display

HDL and HDB Comparison- There are basically two directions of the 3D technology. One is called the (A) parallax barrier the other is called (B) lenticular. Both of these technologies involve the glass lens that lies on top of a normal LCD TFT panel.

- The basis theory behind the parallax barrier technology is that it is a flat lens with the main purpose of blocking light coming from the TFT panel. The blocking of light causes the left eye and right eye to perceive different images which causes a trickery of a persons vision hence the persons brain perceives the object in 3D.

- The basis theory behind the lenticular technology is that it is a curved lens with a very minute curvature located for a group of pixels on the TFT LCD, the curvatures are finite (naked to the eye). This curvature bends light coming from the TFT panel. The bending of this light is very precise and also causes the left and right eye to perceive different images.
