为实现自由立体显示，提出了一种新型指向性背光结构，配合人眼跟踪系统，分时显示具有视差的立体图像对，基于视差原理实现了高清分辨率的多用户自由立体显示。着重阐述了基于AVR单片机的发光二极管阵列时分立体显示背光控制系统，并针对视差立体显示中一直存在的串影问题，从背光控制层面提出了3种改善方法：降低背光点亮时间占空比，倍速刷新液晶显示屏以及卡尔曼预测插值背光刷新数据。实验表明，这3种方法可有效改善串影问题，最终实现了具有较强立体感的无分辨率损失的自由立体显示。

In order to realize autostereoscopic display,a new directional optic structure was proposed,which could provide a pair of parallax images time-sequentially aided with the human eye tracking system,and a high resolution multi-user parallax 3D displayer was invented .Its backlight control system based on single chip microcomputer was elaborated,in view of the crosstalk existed in 3 D displays,three methods were put forward for improvement:reducing lit time ratio of backlight,refreshing LCD at a faster speed,and using Kal-man prediction interpolation .As the experimental results shows,these methods can reduce the crosstalk ef-fectively,and finally a strong 3 D visual sense is achieved without loss of resolution .
