Problems solved by technology

[0002] Projectors are now widely used in a wide range of applications. Projectors are mostly used in school classes, company meetings, vocational training, and product launches. The function of the projector is to project PPT and other images on the screen. Using images to explain, PPT generally contains less text and more content. Most of the content cannot be seen in PPT, and some content is not suitable for PPT. If you are not familiar with the content at this time , you need some reminder materials, some people are holding the speech prompt card, etc., which will affect the lecture effect

Abstract

The invention discloses a liquid crystal polarization invisible mentioning DLP projector system which comprises a light source, a first convergence mirror, a color wheel, a second convergence mirror,a digital micromirror, a digital micromirror driving module, a lens, a liquid crystal panel, a liquid crystal panel control circuit, a subtitle data generation module, a video data generation module,a subtitle superposition module and polarization glasses. The method comprises the steps of: processing the video data through a subtitle superposition module, and projecting the processed video datato an imaging plane through a digital micromirror; after polarizing eyeglass is worn, observing hidden subtitles on an imaging plane; and enabling audiences without polarization glasses not to observethe hidden subtitles on the imaging plane. According to the invention, the design is reasonable, the use is convenient, the projector system can be used as a common projector, the function of givingwords to a speaker can be realized, and the watching of the audience is not influenced.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a liquid crystal polarization invisible teleprompter DLP projector system. Background technique [0002] Projectors are now widely used in a wide range of applications. Most of them are used in school classes, company meetings, vocational training, and product launches. The function of the projector is to project PPT and other images on the screen. Using images to explain, PPT generally contains less text and more content. Most of the content cannot be seen in PPT, and some content is not suitable for PPT. If you are not familiar with the content at this time , you need some reminder materials, and some people are holding lecture notes and reminder cards, etc., which will affect the lecture effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liquid crystal polarization invisible teleprompter DLP projection t...
