Last Updated: September 23, 2026 ⚓ How can a projector create a detailed digital image using millions of microscopic mirrors? The answer lies in the Digital Micromirror Device (DMD), a remarkable microelectromechanical technology developed by Texas Instruments. Introduction: 👉 A Digital Micromirror Device, commonly called a DMD, is a semiconductor-based optical component containing an array of tiny movable mirrors. These mirrors rapidly change position to control the direction of light and help create images, video, patterns, and other forms of precisely controlled optical output. DMD technology is at the heart of Texas Instruments' DLP technology. Depending on the specific device and application. DMDs are used in display and projection systems as well as industrial applications such as 3D printing, machine vision, spectr...
