Abstract

The invention provides an optical machine engine and projection equipment, relates to the field of projection equipment, and aims at solving the problems that in the prior art, the image quality is possibly influenced, the influence of vibration cannot be effectively eliminated, and then noise still exists. The optical machine engine comprises a galvanometer, a support and a mounting shell, the galvanometer is fixed on the support, a first mounting hole is formed in the support, and a first fastener penetrates through the first mounting hole and is fixed with the mounting shell, so the support, to which the galvanometer is fixed, is fixed to the mounting shell through the first mounting hole; and a first vibration reduction pad is arranged in the first mounting hole in a matched mode, andafter the support and the mounting shell are fixed, the first fastener is isolated from the support through the first vibration reduction pad, and the the first vibration reduction pad is at a naturestate. The invention is used for production of projection equipment.

Description

technical field [0001] The invention relates to the field of projection equipment, in particular to an optical engine and projection equipment. Background technique [0002] Projection equipment includes LCD (Liquid Crystal Display) projectors, DLP (Digital Light Processing, digital light processing) projectors, and the like. The core device in DLP projection equipment is DMD (Digital Micromirror Device, digital micromirror device). Due to space and technical limitations, current projection equipment cannot achieve 4K resolution (pixel resolution of 4096×2160) through the DMD chip alone. To achieve 4K resolution, a galvanometer is required. The galvanometer is a planar mirror structure located between the DMD chip and the projection lens that deflects vibrations. The current implementation of home 4K DLP projectors is the structure of a DMD chip plus a vibrating mirror. The working principle of the vibrating mirror is to increase the lower native resolution to 4K through i...
