PROJECTION TYPE DISPLAY SYSTEM, PROJECTION TYPE DISPLAY DEVICE, AND SCREEN

摘要

PROBLEM TO BE SOLVED: To avoid black floating caused in an environment wherein luminance of a circumference of a screen on a picture from a projector is projected is high with simple constitution. SOLUTION: A front projector system uses what is called an electronic paper display (electronic ink) for providing black-and-white display with an electric signal for a screen 31 to be used. The electronic paper display makes a black display image part corresponding to an image 20 projected on the screen 31 black and an image part which is high in luminance and chroma white. Then an optical image (image 20) from a projection type display device is projected and displayed by overlapping. COPYRIGHT: (C)2008,JPO&INPIT
