[0002] Teaching display devices are the core tools for classroom teaching, experimental demonstrations, and science popularization exhibitions. They are tools in the education field for visually comparing knowledge points, experimental phenomena, or historical events. Their technological evolution has always revolved around the three major requirements of information presentation efficiency, interactivity, and interdisciplinary adaptability. During in-plant training, a large number of comparison teaching devices are needed to facilitate trainees' understanding of the training content.

[0003] Currently, traditional teaching display devices have significant limitations. They are static displays lacking comparison dimensions. Traditional wall charts, models, or slides only support single-content presentation and cannot achieve on-screen comparison. Teachers need to manually switch teaching aids, interrupting the classroom coherence. Trainees passively receive information and it is difficult for them to actively explore the differences, resulting in low understanding efficiency for trainees. The display devices in some classrooms are greatly affected by factors such as viewing angles. Large teaching aids are difficult to move, and small devices have a small visible range. Trainees in the back row or corners may not be able to clearly view the display content, and it is not possible to flexibly adjust the height and angle of the display device according to the classroom layout and the line-of-sight height of trainees, leading to poor teaching effects and inconvenience in using teaching in different teaching scenarios.
