Aspect ratio describes the ratio of the width to the height of the screen.
The projector provides a 256-level gray scale and uses eight bits of data per color. Each device has more than 2.3 million mirrors. A resolution of 1920 x 1035 was chosen for demonstration purposes due to the video input source. The DMD also has the resolution capability to handle the proposed North American, high-definition standard of 1920 x 1080. We've made substantial progress, both in contrast ratio and light efficiency, from the standard resolution projector that we demonstrated at SID last year.
