Electronic blackboard-writing multi-screen display system and method based on same PC

Abstract

The invention relates to a multi-screen display technology of computer screen display signals, discloses an electronic blackboard-writing multi-screen display system and method based on the same PC, and solves the problems that according to a multi-screen display scheme in the prior art, the operation is complex, and the multi-screen display scheme is prone to being affected by the resolution of adisplay screen after working modes are switched are solved. Double-screen or multi-screen copy display and asynchronous display are realized in a PC extended display mode, differentiated display requirements are met, and the problems of low teaching efficiency and high cost of a double-all-in-one machine scheme are solved. The operating system based on the same PC works in a double-large-screen or multi-large-screen extended display mode, the content of blackboard-writing software on a main screen is copied, or the content of a front page is extended and displayed, or the content of a specified page is extended and displayed on other extended screens, and the scheme is suitable for application scenes such as multi-screen teaching, office conferences and training speeches.

Description

technical field [0001] The invention relates to a multi-screen display technology for displaying signals on a computer screen, in particular to an electronic blackboard multi-screen display system and method based on the same PC, which is applicable to application scenarios such as multi-screen teaching, office meetings, and training lectures. Background technique [0002] At present, in teaching, office meetings, training lectures and other scenarios, most of them use a single large-screen display solution, that is, there is only one host and one large-screen display, or a touch-screen all-in-one computer is used to realize content display; this single The single-screen display solution has certain disadvantages: first, for application scenarios with a large space, people who are far away from the screen may not be able to clearly view the content displayed on the screen due to the viewing angle of the single-screen display; secondly, the single-screen display cannot satisfy...

AI Technical Summary

Problems solved by technology

[0012] The technical problem to be solved by the present invention is: to propose a multi-screen display system and method based on the same PC for electronic blackboard writing, to solve the problem of tedious operation in the multi-screen display scheme in the traditional technology, and the problem that the resolution of the display screen is easily affected after switching the working mode. The problems brought about by the impact of the PC expansion display mode can achieve dual-screen or multi-screen copy display and asynchronous display to meet the needs of differentiated display and solve the problem of low teaching efficiency and high cost of the dual-in-one machine solution. question
