20250181301
This application claims the priority benefit of Taiwan application serial no. 112146992, filed on Dec. 4, 2023. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
The invention relates to a display system and a display method, and particularly relates to a display method for displaying slides and speaker's notes respectively and a display system suitable for the display method.
When a speaker uses a laptop computer to read or edit a presentation file, the laptop computer may display a slide and speaker notes. The speaker may use the speaker notes to guide the presentation. However, when the laptop is communicatively connected to a projector, an interactive flat panel or an interactive whiteboard, taking the interactive flat panel as an example, since the notebook computer implements a screen mirroring function to allow the interactive flat panel displaying the same image with the notebook computer, when the interactive flat panel displays a slide of the notebook computer, neither the interactive flat panel nor the notebook computer may display the speaker notes.
