Imaging system applied for optical machine of projection device

Abstract

This invention relates to image system for projection device motor, which comprises light machine, prism device, digital micro lens device, projection lens device and light source system, wherein, the prism device and light machine have first slide structure to move relatively and to make prism lens an projection lens get adjustable distance; digital micro lens device and prism lens device have second slide move structure to generate level relative displacement and to make digital lens effective light process area and lens bus bottom position adjustable.

Description

technical field [0001] The present invention relates to an imaging system, in particular to an imaging system used in an optical machine of a projection device, which can easily and conveniently adjust the detailed devices, so that the focus and position of imaging are more accurate. Background technique [0002] Commonly used rear projection systems can be roughly divided into two types: Liquid Crystal on Silicon (LCOS) and Digital Light Processing (DLP) according to optical machine technology. Device (Digital Micromirror Device, DMD), so the image performance is good, becoming the mainstream projection equipment. [0003] FIG. 1 is an optical-mechanical schematic perspective view of a typical reflective digital light processing (DLP) projection device. After the image is generated from the light source system 190, it enters the prism device 120 after passing through the color wheel 191 and the light integrating column, and after being processed by the digital micromirror ...

Problems solved by technology

This is adjusted by using an adjustment jig (not shown in the figure), and then fixed by dispensing glue. Although the relative position between the light source system 290 and the projection lens device 240 is easier to control, the adjustment jig needs to be designed separately, and its operation The procedures on the board are relatively complicated, which makes the adjustment operation time uneconomical, and the special heat-resistant and durable dispensing cost used for fixing is very high, and once the glue is fixed, there is no possibility of recovery and adjustment; for the whole The cost of process cost is not reduced

[0007] In order to effectively achieve the adjustment of image focus and position, and to avoid the lack of complicated procedures, long operation time, high cost and difficult process control, an improved imaging system is produced, so that the optical machine of the projection equipment can be used before leaving the factory. Image quality can be easily adjusted to the best state, making the product quality more stable after leaving the factory, which has become an urgent goal for the industry
