Description

Technical field [0001] The invention relates to the field of environmental art related equipment, in particular to a teaching display device for environmental art design majors. Background technique [0002] At present, many schools have set up multimedia teaching. Teachers display the content of teaching through multimedia. The use of teaching boards is less. However, teachers majoring in environmental design have to involve some animations and some structural extensions when teaching. Multimedia teaching alone does not help students understand well, and teaching boards are still very important.
