ABSTRACT
The Grating Light ValveŒ (GLVŒ) technology is a micromechanical phase
grating. . Operation is based on electrically controlling the mechanical
positions of grating elements to modulate diffraction efficiency.
Thus by providing
controlled diffraction of incident light, a GLV device will produce bright or dark pixels
in a display system .With pulse width modulation, a GLV device will produce precise
gray-scale or color variations. Built using micro electromecha nical system (MEMS)
technology, and designed to be manufactured using mainstream IC fabrication
technology, the GLV device can be made both small and inexpensively. A variety of
display systems can be built using GLV technology each benefiting from the hig h
contrast ratio, fill ratio, and brightness of this technology. In addition, GLV technology
can provide high resolution, low power consumption, and digital gray -scale and color
reproduction
