Abstract

The invention provides a projector and its optical machine. The optical machine includes an optical machine housing and a DMD assembly arranged on the optical machine housing. The circuit board includes a first PCB board and a second PCB board. A part of the plurality of electronic devices is arranged on the first PCB board, and the other part is arranged on the second PCB board. PCB board, the electronic device arranged on the second PCB board includes a non-volatile storage device; the first PCB board is arranged on the back side of the optical machine housing, and the compression structure compresses the first PCB board and the connector to the DMD device , the second PCB board is arranged on the bottom side of the optical machine housing; the first side of the first PCB board close to the second PCB board is connected to the second PCB board through the first flexible circuit board, and the first PCB board is connected to the first PCB board The second side opposite to the side is connected with a second flexible circuit board, and the second flexible circuit board is used for electrical connection with external devices, so as to make full use of the bottom surface space of the optical chassis and make the structure of the optical chassis more compact.

Description

technical field [0001] The invention relates to the technical field of DLP projection, in particular to a projector and its optical machine. Background technique [0002] Micro-projection technology is a new type of modern projection display technology. With its miniaturization and portability, it gradually penetrates into people's daily life, and has gradually become an important development trend of projection display. The digital light processing (Digital Light Processing, DLP) projection display method has the characteristics of high brightness, high contrast, and high resolution. It is combined with a new LED light source to realize a miniaturized portable micro-projection, which meets people's desire for portable and free projection display. demand. [0003] The circuit board in the optical engine of the existing DLP projector is set as a whole board structure. In order to realize the reliable installation of the circuit board, it is necessary to match the optical cha...
