Problems solved by technology

[0002] As a commonly used tool in teaching work, the writing board is generally monochrome and cannot be self-illuminated. Long-term use will cause user eye fatigue and reduce teaching efficiency. It cannot adapt to the current situation where the learning pace is getting faster and faster. The traditional writing board needs manual erasing, which is more harmful to the human body, increases labor intensity, wastes time, is difficult to realize automation, has great disadvantages, and needs to be improved

Description

technical field [0001] The invention relates to the technical field of teaching, in particular to a luminescent writing board. Background technique [0002] As a commonly used tool in teaching work, the writing board is generally monochromatic and cannot be self-illuminated. Long-term use will cause user eye fatigue and reduce teaching efficiency. It cannot adapt to the current situation where the learning pace is getting faster and faster. The traditional writing board needs to be erased manually, which is harmful to the human body, increases labor intensity, wastes time, and is difficult to realize automation. It has great disadvantages and needs to be improved. Contents of the invention [0003] Aiming at the deficiencies of the above technologies, the present invention proposes a light-emitting writing board. [0004] The present invention is a light-emitting writing board, comprising a main frame body and a reset device arranged in the main frame body, the main frame...
