| 摘要 | 为了研制出不需要立体眼镜，且兼容平面显示的自动立体显示屏，利用液晶制作出透光狭缝，放在面板和背光源之间，使之加上电压时只有狭缝透光，背光变成一排平行的线光源，照射液晶屏时每个光源对应4列子像素，左右眼只能看到不同像素，进而产生立体感。不加电压时背光变成面光源，和普通液晶显示屏一样显示平面图像。为了减少面板表面防眩偏振片的影响，用减反射涂层覆盖防眩偏振片。通过改变普通液晶屏的背光，以及对普通液晶屏表面进行处理，制作出了4个视点的立体显示屏，实现了立体显示和平面显示的切换。该技术方案可满足批量生产的要求。 |
| 其他摘要 | For fabricating the autostereoscopic liquid-crystal display panel, the backlight was changed and the front side of the panel was modified. A llquld-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 subpixels 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 antl-glare polarizer is coated with an antl-reflectlve 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. |
