DIGITAL LIGHT PROCESSING TECHNOLOGY

ABSTRACT

DIGITAL Light Processing (DLPTM) is a revolutionary new way to project and display information. Based on the Digital Micromirror Device (DMDTM) developed by Texas Instruments, DLP creates the final link to display digital visual information. DLP technology is being provided as subsystems or “engines” to market leaders in the consumer, business, and professional segments of the projection display industry. In the same way the compact disc revolutionized the audio industry, DLP will revolutionize video projection.

INTRODUCTION

DLP has three key advantages over existing projection technologies. The inherent digital nature of DLP enables noise-free, precise image quality with digital gray scale and color reproduction. Its digital nature also positions DLP to be the final link in the digital video infrastructure. DLP is more efficient than competing transmissive liquid crystal display (LCD) technology because it is based on the reflective DMD and does not require polarized light. Finally, close spacing of the micromirrors causes video images to be projected as seamless pictures with higher perceived resolution. For movie projection, a computer slide presentation, or an interactive, multi-person, worldwide collaboration DLP is the only choice for digital visual communications, today and in the future.
