Cooling for Digital Light Processors

February 17, 2021 by Laird Download White Paper

 

Digital light processors (DLPs) employ a laser light source and millions of tiny mirrors to produce vibrant, high-resolution images for a wide variety of industries and applications. It is critical to maintain an optimum operating temperature during use to prevent degradation of the digital light processing technology. Active cooling solutions utilizing thermoelectric coolers can provide DLP thermal management in a wide range of high-temperature applications. 

DLP technology is based on optical micro-electro-mechanical systems (MEMS) technology. It uses a grid of microscopic, highly-reflective aluminum mirrors placed on a semiconductor chip known as a digital micromirror device (DMD). A DLP chip uses millions of micromirrors to project sharp, crisp images with extremely high feature resolution and vibrant colors. 

In this application note from Laird Thermal Systems, learn about cooling for digital light processors and how it can be used in automotive, display and projection, and advanced light control applications.
