Description

[0001] Field [0002] The invention relates to a large-screen electronic display screen, in particular to a multifunctional large-screen electronic teaching display screen that can replace the original blackboard for teaching. Background technique [0003] At present, in the thousands of years of teaching in our country, the traditional teaching method is that the teacher imparts all the knowledge to the students through the blackboard, so the teacher has always been known as the teacher who eats chalk dust.

Bring certain harm to human health. In addition, when manufacturing blackboards, most of them are painted with black lacquer, so there is reflection phenomenon on the blackboard to a certain extent, so that students...
