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 an invisible prompting projector system which comprises a light source, a first convergence mirror, a color wheel, a second convergence mirror, a digital micro-mirror, a digital micro-mirror driving module and a lens, and further comprises a frame synchronization signal transmitting module, liquid crystal glasses, a subtitle data generation module, a video data generation module and a subtitle superposition module. Video data is processed through the subtitle superposition module, the processed video data is projected to the lens by the digital micro-mirror, and a projection area is formed on an imaging plane. After the pair of liquid crystal glasses is worn, hidden subtitles can be observed on the imaging plane. Audiences without the liquid crystal glasses cannot observe the hidden subtitles on the imaging plane. The video data on the imaging plane under the visual angle of the audience has the same effect as video data projected by a common projector. According to the invention, the design is reasonable, the use is convenient, the projector can be used as a common projector, the function of prompting 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 an invisible teleprompter projector system. Background technique [0002] Nowadays, the scope of projector application is very wide. The projector is 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. The speaker should combine the projection In terms of images, PPT generally contains less text and more content. Most of the content is not visible on PPT, and some content is not suitable for PPT. At this time, if you are not familiar with the content , You need some reminder materials, some people are holding presentation cards, etc., which will affect the lecture effect. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an invisible teleprompter projector system that is reasonable in design and convenient to use, ...
