From the QM-HL4200 of push-pull green board product parameters, teaching process to on-site acceptance, analyze how Qtenboard can use MT9679/RK3588 multi-platform chip configuration, Q AI system-level framework and supporting push-pull green board scheme to help schools and integrators design a landing smart classroom teaching wall.

October 2026Qtenboard integration schemeRead for about 16 minutes.

Instead of replacing traditional blackboard writing, let the two teaching methods coexist. The digital classroom should not allow teachers to abandon the familiar habit of writing on the blackboard. Teachers need to use green boards to write deductions, list steps or draw pictures. At the same time, they need to open courseware, videos, experimental demonstrations or students' screen casting. In the middle, they need to cut back the blackboard writing from the digital content and then return to the courseware explanation. After class, they need to save some blackboard writing, annotations or classroom contents.

The integrated value of the push-pull green board and the interactive whiteboard lies in allowing teachers to choose blackboard writing or digital content according to the teaching rhythm, rather than being forced to switch back and forth between the two teaching methods. The integration plan should be designed around the real classroom process, not just complete equipment installation.

Summary save.Save courseware comments, screenshots, or class content by project configuration. The Q AI supports the generation of structured class summaries in 5 seconds. Qtenboard whiteboard content can be saved with one click, supporting export PDF or picture.

Take math class as an example: teachers first use Qtenboard interactive whiteboard to show examples, slide out QM-HL4200 green board to write problem-solving steps, slide back to whiteboard to use courseware or comments when explaining graphics, and save whiteboard content after class for students to review or teachers to reuse.

Take science class as an example: teachers use Qtenboard whiteboards to display experimental principles or videos, and use QM-HL4200 green boards to record experimental steps and observation results. When real objects or experimental materials need to be displayed, they can combine video booths to save experimental conclusions or key contents as classroom materials.

4. equipment mix and classroom layout

Teaching wall is not a simple splicing, need to confirm the size, operation and viewing relationship

The common combination mode is: the Qtenboard interactive flat plate is centered, and the outer green plate is QM-HL4200 to slide. When the green plate is closed, it forms a complete writing surface with a total length of ≥ 4000mm. During multimedia teaching, the movable board slides open to reveal the interactive tablet. Green board can expand the board book area, service large class or large space classroom.

The classroom layout verification needs to confirm the classroom width, viewing distance and rear line of sight. Whether the sliding direction of the green board is affected by the platform, door or passage; Whether the teacher's operation height and writing range are appropriate; Whether the sliding of the green board will block the students' sight; Whether it is necessary to move the bracket, wall hanging or embedded installation. In terms of size adaptation, it is necessary to check the size of the Qtenboard interactive flat plate (55-110 inches), the total width of the QM-HL4200 green plate ≥ 4000mm, the height adjustable according to the size of the flat plate, the length and installation position of the track, the available width of the classroom wall surface, and the space of the platform, desks and chairs and passages.
