Optical engine module

An optical engine module, comprising:

• a circuit board, a light valve module, a thermal conductive member, and a supporting member, wherein
• the circuit board has a first surface, a second surface opposite to the first surface, a first opening hole and at least one second opening hole, the first opening hole and the at least one second opening hole are separately disposed at the circuit board, the first opening hole penetrates through the first surface and the second surface and the at least one second opening hole penetrates through the first surface and the second surface;
• the light valve module is disposed on the first surface and is electrically connected to the circuit board, and the light valve module has a light emitting surface and a back surface opposite to the light emitting surface;
• the thermal conductive member is disposed on the second surface of the circuit board, and a part of the thermal conductive member is thermally connected to the back surface of the light valve module through the first opening hole of the circuit board;
• and
• the supporting member is disposed on one side of the first surface of the circuit board, the supporting member is partially in contact with the light valve module and at least one portion of the supporting member extends into the at least one second opening hole of the circuit board along an extending direction and is thermally connected to a plane of the thermal conductive member disposed on the second surface of the circuit board, wherein the plane of the thermal conductive member is perpendicular to the extending direction, wherein an orthogonal projection of the at least one second opening hole on the plane of the thermal conductive member is overlapped with an orthogonal projection of the at least one portion of the supporting member on the plane of the thermal conductive member.
