Pixel buffer circuits for implementing improved methods of displaying grey-scale or color images
TLDR
In this article, a spatial light modulator can store pixel data in a plurality of small circuits coupled to pixel mirrors and simultaneously drive these pixel mirrors a frame at a time, which can convert binary images to grey-scale images and separate red, green and blue images into color images.Abstract:
A device such as a display device or a spatial light modulator can store pixel data in a plurality of small circuits coupled to pixel mirrors and simultaneously drive these pixel mirrors a frame at a time. This device is particularly beneficial for implementing improved image quality techniques which can convert binary images to grey-scale images and/or separate red, green and blue images into color images and displaying those images using the natural process of integration which occurs when a person views images at sufficiently high rates.read more
