大动态宽幅度自由立体显示背光控制系统

Backlight Control System of Autostereoscopic Display with Large Dynamic and Wide Range

提出并实现一种大动态宽幅度自由立体显示背光控制系统。本系统采用LCD作为基本显示屏幕,以柱镜光栅作为指向性光学部件,以LED阵列作为可寻址背光组件,以步进电机改变栅屏距离,采用Atmega128单片机作为控制处理器,辅以高精度实时人眼跟踪模块与之通信。本系统的大动态体现在观看视角较大且连续,宽幅度体现在可同时满足多个有效观看距离。

A large dynamic and wide range autostereoscopic display backlight control system is proposed and real-ized. The system uses LCD as the basic display screen,uses lenticularlensas a directional optical component,usesLED array as the addressable backlight module,uses stepper motor to change the distance between lenticular lensand screen,uses Atmega 128 microcontroller as the control processor,combined with high accuracy real time eyetracking module to communicatewith it. The system of the large dynamic reflected in viewing angle large and contin-uous,and the wide range reflected in itcan meet multiple effective viewing distance.
