Problems solved by technology

[0008] However, in actual application, the above-mentioned integrated application structure of the projector and the projection screen and the electronic whiteboard and the computer platform has the following disadvantages: an external wire is required to connect the computer platform 20 to the projector 30, and if the electronic whiteboard is connected The interface 11 is a wired RS-232 communication interface, and an external wire is also required to connect the computer platform 20 to the electronic whiteboard 10, which makes the application more inconvenient and tends to make the display venue appear cluttered due to the existence of the external wire. Therefore, it affects the display work; moreover, when the user uses the projector 30 every time, he must adjust the projection angle of the projector 30 to accurately align the optical image sent by the projector 30 to the Therefore, the preparation work is time-consuming and labor-intensive and reduces efficiency; in addition, when the projector projects data onto the screen, the image of the lecturer or operator is likely to interfere with the displayed data projected on the screen, such as personal operation When the dynamic image is projected on the screen at the same time to form a black shadow, it blocks the display of the data. Therefore, when explaining and processing the presentation, the lecturer or operator cannot move or change the operating range arbitrarily, and it is easy to make the information difficult to access. The display is disturbed

Abstract

A projector has at least one projection processing module with at least one optical lens. Said module can receive screen displaying data, convert it to optical image and project it via lens onto a screen. Its feature is that said projection processing module can be selectively arranged at any side of screen, so having no need of regulating its projecting angle.

Description

technical field [0001] The present invention relates to an image display technology, in particular to a projection device for projecting and displaying an image on a desired display area. Background technique [0002] At present, the projectors commonly seen on the market can be divided into several types of projectors, such as transparent sheet type, slide projector type, three-gun type, liquid crystal projection panel and single-gun type. The text is projected onto a larger screen or flat board, so that more people can watch the content of the file at the same time. Even a newer generation of projectors can also be connected to notebook computers or desktop computers, so that images, text or tables can be directly projected, so as to avoid problems such as flat paper or unclear text that affect the overall projection Effect. [0003] Due to the rapid development of electronic technology, the above-mentioned projector can also be used in conjunction with an electronic whi...
