Manufacture of multi-view-point auto-stereoscopic LCD panel

For fabricating the autostereoscopic liquid-crystal display panel, the backlight was changed and the front side of the panel was modified. A liquid-crystal device was inserted between the backlight and the TFT LCD panel. Every pixel in the device is a slit. By the Moire fringe (picket fence effect), the device and LCD panel were aligned. When driven with voltage, the backlight is converted into a large number of thin, bright, vertical illuminating lines, between which there is a dark space. Every light source corresponds to four columns of subpixels as the liquid-crystal display panel is illuminated. Sitting at the average viewing distance in front of the display, the observer′s left eye sees only the information on some columns of sub-pixels, and the right eye sees only what is on the other columns. Without voltages, the backlight functions just like the normal LCD, the module can display the normal two-dimension images. The front side of anti-glare polarizer is coated with an anti-reflective layer to avoid light diffusion. The autostereoscopic TFT liquid-crystal display module is a multi-view system, and can display stereo and plane images. The technology can be adopted in mass production.
