Abstract:
1. A digital micromirror device module, comprising: a circuit board, comprising a first surface, a second surface and a through hole, wherein the first surface is opposite to the second surface; a digital micromirror device element, electrically connected to the circuit board; a soft elastic pad, disposed on the first surface of the circuit board and surrounding the through hole; a heat dissipation pad, passing through the through hole and contacting the digital micromirror device element; and a heat sink, wherein the soft elastic pad is sandwiched between the circuit board and the heat sink, the heat dissipation pad is sandwiched between the heat sink and the digital micromirror device element, and the heat sink contacts the soft elastic pad and the heat dissipation pad to apply a force to the soft elastic pad and the heat dissipation pad.
