Abstract

The invention discloses a DMD assembly, a DLP light machine module and a DLP projector. Wherein the DMD assembly comprises a circuit board, a DMD seat and a DMD chip, the DMD seat comprises an insulating body, a conductive elastic piece and a conductive block, the insulating body is provided with a first surface and a second surface which are oppositely arranged, the conductive block is arranged on the first surface, and the conductive block is welded and connected to the circuit board; and the conductive elastic piece is arranged on the second surface and is electrically connected with the conductive block, and the DMD chip is fixed on the second surface and is connected with the conductive elastic piece. According to the technical scheme, the technical problem of poor contact between the DMD chip and the circuit board is solved, and the contact reliability between the DMD chip and the circuit board is improved.

Description

technical field [0001] The invention relates to the field of optics and projection technology, in particular to a DMD component, a DLP optical machine module and a DLP projector. Background technique [0002] DMD (Digta1Micromirror Device, digital micromirror device) is a key device in a DLP (Digtal LightProcession, digital light processing) projector. The DMD chip is connected to the circuit board through the DMD adapter. If there is poor contact between the DMD chip, the DMD seat or the circuit board, it will not only affect the display quality of the product, but also easily cause damage to the DMD chip. The two opposite surfaces of the traditional DMD seat are all provided with elastic pins, and the DMD chip, the DMD seat and the circuit board are locked by screws, so that the elastic pins on the two surfaces of the DMD seat are respectively connected to the DMD chip and the circuit board. The pins are contacted to realize the communication between the DMD chip and the ...
