DIGITAL MICRO-MIRROR DEVICE ASSEMBLY FOR OPTICAL PROJECTION SYSTEM

摘要

A DMD(Digital Micro-mirror Device) assembly of an optical projection system is provided to remove the use of screws, reduce the number of components, and save material cost by caulking and assembling a heat radiating member. A DMD circuit board(10) loads various IC chips necessary for forming images. A heat radiating member(20) radiates heat generated when the IC chips are driven. The first holder(30) contains and supports the DMD circuit board(10). The second holder(40) is combined to the first holder(30), and the heat radiating member(20) is caulked and fixed in the second holder(40).
