一种超高清激光电视系统的设计方案

摘要

文章介绍一种超高清激光电视系统的设计方案,详细阐述了方案的设计原理.系统TV SOC模块将电视信号处理成像素为4M×2N@f的超高清图像信号,图像处理模块对超高清图像信号进行采样、分割和倍频处理后得到2路（√2 M×√2）N@2f的高清图像信号,DMD驱动模块对2路高清图像信号进行合并处理得到（2√2M×√2N@2f）图像信号来驱动DMD芯片,DMD芯片投射出分辨率为（2√2M×√2N）的图像光;采用振镜使DMD投射的相邻帧图像光位置微移,从而显示出4M×2N@f的合成画面.该方案可以快速应用于超高清激光电视产品,具有广泛应用价值.%The article describes a Solution for Ultra High-definition Laser TV System.The principle of the solution are highlight-ed.First,TV SOC module of the system processes TV signals into Ultra High-definition image(named UHD)signal with a frame rate of f and 4M×2N pixels per frame.Image processing module extracts pixels from the 4M×2N image and divides the UHD sig-nal into two High-definition (named HD)image signals,and each HD image signal with a frame rate of 2f and（√2M×√2N） pix-els per frame.DMD driver module combines the two HD image signals into image signal with the same frame rate and （2√2M×√2N）pixels per frame and then drive a DMD chip.The DMD chip is drived and emit light to form a light image with（2√2M×√2N）resolution.Two adjacent light images are micro optically shifted by an Actuator to present an synthetic picture with 4M×2N resolu-tion on the screen.Finally,under the drive of the image signal with（2√2M×√2N@2f,）continuous pictures with a frame rate of f and 4M×2N resolution are presented on the screen.The solution can be quickly applied to Ultra High-definition Laser TV,and can be spread widely.
