Problems solved by technology

However, the cost of this six-axis adjustment machine is high, the size of the equipment is large, and professional personnel are required for maintenance. The thermal expansion coefficient of the UV light-cured adhesive is different from that of the glued material, and the imaging quality of the produced projection display is unstable. In addition, the laser welding method takes a long time to align with the light
It can be seen from the above description that the aforementioned method has disadvantages such as high equipment cost and inconvenient use.

Embodiment Construction

[0013] The optical path adjustment mechanism of the projection display of the present invention will be described in detail below through a preferred embodiment and accompanying drawings.

[0014] As shown in Figures 1, 2, and 3, the best embodiment of the optical path adjustment mechanism 10 of the present invention is a group of three, and they are installed together in a projection display 1 for adjusting the optical paths of the three color lights, assuming a projection display 1. When there are two colored lights to be processed, the number of the optical path adjustment mechanisms 10 is two. In the state of use shown in FIG. 2 , the projection display 1 has two mirror bases 11 (only one is shown in FIG. 2 ), and a beam splitter 12 (not shown in FIG. 2 ) clamped on the mirror base 11 , the beam splitter 12 allows at least one color light to be projected from a light exit surface 121 , and then transmitted to the light path adjustment mechanism 10 . And each optical path ...

Abstract

A light-path regulation mechanism of projection display consists of a light valve being set in interval way to light splitter and a regulation unit. It is featured as forming said regulation unit by regulation base being set between said light valve and said light splitter as well as fixing component set on said base and used to vary angle of said light valve then enabling to use such simple mechanical structure to vary position and angle between light valve and regulation base.

Description

technical field [0001] The invention relates to an optical path adjustment mechanism, in particular to an optical path adjustment mechanism of a projection display. Background technique [0002] Projection display is a common electronic device. In order to improve the quality of the projected picture, the projection positions of red, green and blue colors in the projection display and the modulation of the three colors of light are then converged into one beam and emitted. The optical path adjustment function becomes very important. Therefore, when manufacturing projection displays, the industry must first adjust the position and angle of the LCD panel and other components in the projection display to the best state, and then combine them with each other to achieve a good optical path adjustment. Function, in order to facilitate the light splitting and combination of each color light. [0003] In the past, there are two ways in the industry to adjust the position and angle...
