【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。更多还原

【Abstract】 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 twodimension 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.更多还原
