Multi-Screen Smart Classroom Environment Components
Configure the teacher's main and secondary displays at the classroom frontend: the main display presents lecture content, while the secondary display shows content and control panels to the teacher. Place group screens evenly across the center of the classroom, with one companion device assigned to each learning group.
The teacher host and all student group devices connect to a single switch via wired network. The switch links to an AP or router to form the classroom LAN. Screen sharing, broadcasting, and device calls are handled entirely within the classroom LAN, without relying on external bandwidth.
Teacher Dashboard
Connect to a TV, projector, or all-in-one device via Projector HDMI to present main content.
Teacher Secondary Display
Connect a monitor via HDMI to the podium display for content viewing and control.
Group Display
Each learning group has a display driven by the HDMI output from the group's slave unit.
Touch Control
When the display device is a touchscreen, connect to the touch port via the smart terminal's USB port for touch control.
Six Multi-Screen Collaboration Capabilities
The group discussion teaching solution covers the full workflow—from individual screen sharing to in-group content sharing—with one-click operations.
Wireless Screen Sharing: Teacher and Group Views
The teacher's station and each learning group have a display screen, allowing the teacher and students to wirelessly share content from computers or mobile devices.
Main Screen Content Broadcast
Presenter can broadcast the main screen content to other group screens with one click, sharing the same presentation materials.
Cast group screen to main screen
Presenters can display content from one or more group screens on the main display for presentation or comparison.
Broadcast group screen to other group screens
First, pull content from a group to the main screen, then push it to other group screens for demonstration.
Teacher Mode: Dual-Screen Sync
The main screen displays only content, while the secondary screen shows both content and a control bar. Teachers can manage multi-screen operations by simply facing their student groups.
Teacher: Multi-Source Simultaneous Display
The main screen displays multiple video sources simultaneously—including wired input, wireless screen sharing, and network input from sub-screens—and supports customizable layouts.
Usage in the Classroom
Before the session begins, the presenter broadcasts the content displayed on the main screen at the front of the classroom to all learning group screens, introducing the problem to be solved or the exercise to be completed.
During class, each group shares content on its group screen for discussion. The presenter can display a specific group's content on the main classroom screen to highlight that group's progress.
Near the end, the presenter shares individual group content with other groups for feedback and suggestions. These operations rely on direct, simple video streaming and multi-screen collaboration capabilities.
System Connection and Deployment
The teacher station connects its Projector HDMI port to the main display and its Monitor HDMI port to the lectern control screen. Each student group's device connects via HDMI cable to its respective group display.
All smart terminals connect via wired network to a single switch, which then connects to an AP or router to form an interconnected classroom LAN.
Main Screen Output
Connect projector via HDMI directly to TV, projector, or all-in-one touch screen.
Auxiliary Screen Output
Monitor HDMI connection to podium display or all-in-one touch screen, with a dedicated side menu.
Group Screen Output
Group slave HDMI output to group display.
Network Configuration
Wired access switch for terminals; uplinks to APs or routers to form a LAN.
