Abstract

The present invention provides a projection device, comprising: a signal input unit, configured to receive a video signal generated by a video source; a signal output unit, configured to transmit the video signal received by the signal input unit to a signal image processing unit; a signal image processing unit, configured to receive the video signal transmitted by the signal output unit, process the image of the video signal and project it for display; the signal output unit is also used to receive the video signal received by the signal input unit After the video signal is processed, it is output as an input signal of a signal input unit of another projection device. The invention also provides a projection system and a projection method. Compared with related technologies, the projection equipment, projection system and projection method of the present invention are low in cost and easy to use.

Description

technical field [0001] The present invention relates to the technical field of light and shadow display, in particular to a projection device, a projection system and a projection method. Background technique [0002] With the development of the intelligent era, light and shadow display has become a development trend and has been used in more and more fields, such as projection equipment, especially in large-scale exhibitions, conferences, and teaching. [0003] In some special occasions, such as product exhibitions, large conference rooms or auditoriums, multiple display screens (projection) are required, and the same content needs to be displayed synchronously. For example, large lectures require display screens in different positions to display the same content. [0004] Among the projection devices of the related art, the external VGA signal splitter is widely used to realize one input and multiple outputs. However, on the one hand, this method will increase a certain c...
