From childhood to adulthood, the blackboard is the educational equipment required for modern education. What we came into contact with at first was the traditional blackboard, made of board files, glass, etc. But in recent years, the mobile writing board has also appeared and tends to replace the blackboard.

From a health point of view, we know that green can protect the eyes. In addition, when the black-white contrast is not too distinct, the mobile writing board can reduce the damage to the eyes, so writing on a green blackboard with chalk does not hurt the eyes and helps protect eyesight.

In terms of contrast, black and white is a sharp contrast, which can show better text content in teaching applications. Black means that visible light does not enter the visual range. White means that all visible light enters the visual range at the same time, emphasizing white content against a black background. Therefore, from a teaching point of view, the blackboard is better than the green blackboard.

Some people say it is better to use glass whiteboards; one cannot deny that they are indeed very good. But this mobile writing board is suitable for home and office. Special classrooms are very bright, and whiteboards easily reflect light, so students need to tilt their heads to see clearly, which is not good for eyesight.

In particular, the price of electronic boards must be higher than ordinary blackboards. There are many classrooms in schools. It is especially a little difficult for all classrooms in ordinary schools to use electronic whiteboards. Therefore, under the premise of protecting the health of teachers and students and within the school's affordable budget, the mobile writing board is very suitable for education.

The green of the mobile writing board is a common color in nature, and green plays a protective role. The green spectrum is more easily absorbed by the human eye than other colors, so students sitting in the back of the classroom can see the green board more clearly. Not only that, the magnetic surface of such a mobile writing board has no problem with stickers and small items; during class meetings in the classroom, it can be used as a display wall and blackboard news.
