Abstract

The projection type color display device includes one light source, one digital lens combination, one projecting lens, one projecting space and one projecting screen. The digital lens combination includes successively arranged silicon substrate, CMOS, metal layer, twisting pivot layer and reflecting mirror layer. White light from the light source is reflected in the digital lens combination to form red light, green light and blue light combined randomly and transmitted to the projecting lens before passing through the projecting space and reaching the projecting screen.

Description

【Technical field】 [0001] The invention relates to a color display device, in particular to a projection type color display device. 【Background technique】 [0002] With the development of HDTV (High Definition TeleVision, high-definition television), color projection display technology and its devices are playing an important role. A color projection display device is a device that uses an optical system and a projection space to magnify a color luminescent image and display it on a projection screen. [0003] A projection-type color display device is usually composed of a display device for displaying a color luminous image, a projection optical system, a projection space and a projection screen. The display device can be composed of one color display device or three monochrome display devices of red, green and blue, or one group of color display devices or multiple groups of red, green and blue monochrome display devices. The function of the projection screen is to provid...
