激光显示组件及系统研发中心

激光显示组件及系统研发中心

激光显示与传统显示(CRT、等离子、液晶、LED等)相比具有色域范围大(传统显示的2.5倍)、色彩丰富、色饱和度高、颜色表现力强(传统电视的2倍)、光源寿命长(传统电视的5倍)、维护成本低、生产线投资规模小(传统显示生产线1/20)、环保节能(功耗为传统电视1/3)等优点,被誉为“人类视觉史上的革命”,也被誉为继黑白显示、彩色显示、数字显示之后的“第四代显示技术”;同时,各类显示终端既是现代文明传播的重要途径,也是文化装备范畴的核心内容。

主要研发方向:

1) 半导体RGB激光器芯片、封装及器件总成;

2) 基于LCOS、DLP或者MEMS等的激光投影机;

3) 激光显示大屏幕产品及激光微投影系统;

4) 基于云平台、智能化、短焦距和全息技术的新一代激光显示。
