Problems solved by technology

However, since the three-lens reflective LCD panel projector has three projection lenses, the required projection distance is relatively certain. In different places of use, this projection distance will be limited and affected. In some cases, it can be solved by moving the projector (the screen is generally inconvenient to move, for example, a fixed wall is usually used as a screen), but in other cases, it will be difficult to move the projector (limited by the environment and the number of

Abstract

The invention supplies a three lens reflecting type liquid board projector that could automatically align pixel. The feature is that it has a control and adjusting structure that could automatically align pixel in the projector. The structure includes a long shaft, a support, a CCD, two step motors and at lest one control circuit. The input end of control circuit connects to electric coupling component to receive testing signal, and the output end of control circuit connects to step motor to control the actions. The invention could sharply improve convenience for user, and ensure projecting effect.

Description

technical field [0001] The invention relates to a projector, in particular to an automatic pixel alignment three-lens reflective liquid crystal panel (LCOS) projector. Background technique [0002] Projectors are widely used in education, business and home. A common projector generally includes a casing and a light engine, a circuit board, a lighter, a light source and a corresponding heat dissipation mechanism arranged in the casing. According to the number of lenses used in the light engine, projectors can be divided into single-lens projectors and three-lens projectors. In terms of design, the white light generated by a light source is generally separated into red, green and blue three-color light, and the three-color light is modulated by three liquid crystal light valves respectively. The modulated three-color light is designed according to the single-lens or three-lens design. Different methods are used to deal with it. In a single-lens projector, the three-color li...
