摘要 为了制作不需要立体眼镜的自动立体显示器,文章对显示屏驱动电路进行了研究,并调查了多种立体显示屏上像素和图像的排列规律及立体输入信号的具体格式,制作了立体信号变换电路,该电路主要由FPGA和QDRSRAM构成,放在Scaler和LVDS电路之间,对输入信号进行处理,最终发送到显示屏中相应的像素上。此电路可以适应多种液晶立体显示屏,并兼容多种立体信号源。通过实验表明整体技术和方案是成功的,可用于改进各种车辆、舰船和飞机的显示系统。 The driving circuits for autostereoscopic displays have been developed.With autostereoscopic displays,the three dimension images would be displayed,and no headgears needed.Some kinds of stereo video signals have been investigated,and after analysis of some optical technologies of auto stereoscopic displays,the transformation of images and pixels has been designed.The new circuit board has been developed,the board includes two FPGAs and QDR SRAMs.The new board is inserted in the driving circuits of ordinary LCD,between the scaler and the LVDS interface.It receives the signals,stores the images for right eyes to RAMs,and other images to another RAMs,then transforms them,transports the new signals to the LVDS interface and the LCD panel.The drive circuit is suitable for kinds of autostereoscopic displays and stereo video signals,and its functions can be easily extended and changed by VHDL codes.They can be used in vehicles,ships and planes.
