But have you ever wondered who invented this revolutionary technology? In this article, we will delve into the history of the Digital Micromirror Device and uncover the brilliant mind behind its invention.
The Birth Of The Digital Micromirror Device
The Digital Micromirror Device was first conceived in the late 1970s by a team of researchers at Texas Instruments (TI). The team, led by Dr. Larry Hornbeck, was working on a project to develop a new type of display technology that could produce high-quality images using a digital signal. At that time, display technologies were limited to analog systems, which were prone to distortion and had limited resolution.
Dr. Hornbeck, an American physicist and engineer, is credited with inventing the first Digital Micromirror Device in 1977. He developed a device that used a matrix of tiny mirrors to reflect light and create images. Each mirror was controlled by an electrostatic charge, which allowed it to tilt and reflect light in a specific direction. This innovative design enabled the creation of high-resolution images with unprecedented brightness and contrast.
The Science Behind The Digital Micromirror Device
The Digital Micromirror Device works on the principle of electromechanical deflection. Each mirror is attached to a hinge and can be tilted by applying an electrostatic charge. When a mirror is tilted, it reflects light in a specific direction, creating a pixel on the screen. The mirrors are arranged in a matrix, with each mirror corresponding to a specific pixel. By controlling the tilt of each mirror, the DMD can create a wide range of images, from simple text to complex graphics.
The DMD uses a technique called binary pulse-width modulation (PWM) to control the mirrors. In this technique, the mirrors are switched on and off at high speed, creating a series of pulses that correspond to the desired image. The human eye integrates these pulses, creating the illusion of a continuous image.
