由单片DMD、200 W UHP光源、RGBRGB 6段4倍速色轮、20层液晶光阀组成的显示体、投影镜头、折叠光路、控制电路等部分组成。对该显示器的色度学特性进行了分析
其色域是NTSC标准的53.8%
色温是5 401 K。色轮是影响色域的主要因素之一
选择新的色轮后
色域提升至NTSC标准的69.7%。
Abstract
A kind of solid volumetric true 3D display device was developed in this paper. The sample device consists of a single DMD
a UHP of 200 W power
a color wheel of RGBRGB and 240 Hz
20 LC shutters
projection lens
folder mirrors
control circuits
etc. The colorimetric characters of the display device were studied. The color gamut reaches 53.8% of NTSC standard
and the color temperature is 5 401 K. Color wheel is one of key factors affecting the gamut. The color gamut can increase to 69.7% of NTSC standard with the involvement of a new color wheel.
