Paper Abstract

Autostereoscopic displays with flat panel liquid crystal display and lenticular sheets are receiving much attention. Multiview 3D-LCD is truly autostereoscopic because no head tracking is necessary and the technology is well poised to become a mass market consumer 3D display medium as the price of liquid crystal displays continues to drop. Making the viewing experience as natural as possible is of prime importance. The main challenges are to reduce the picket fence effect of the black mask and to try to get away with as few perspective views as possible. Our solution is to 'blur' the boundaries between the views. This hides the black mask image by spreading it out and softens the transition between one view and the next, encouraging the user to perceive 'solid objects' instead of a succession of flipping views. One way to achieve this is by introducing a new pixel design in which the pixels are slanted with respect to the column direction. Another way is to place the lenticular at a small (9.46 degree) angle with respect to the LCD columns. The effect of either method is that, as the observer moves sideways in front of the display, he always 'sees' a constant amount of black mask. This renders the black mask, in effect, invisible and eliminates the picket fence effect.
