Problems solved by technology

At present, the blackboards in the prior art generally have the shortcomings of reflection and sticky dust. The blackboards seen at certain angles are prone to reflections, and the materials for making blackboards generally use wood, iron, glass and other materials. In addition to the shortcomings of easy dust and environmental pollution when writing, the blackboard made of these materials also has the disadvantages of easy cracking, deformation, and waste of wood; the blackboard made of iron plate also has the disadvantages of easy oxidation, rust, Disadvantages of delamination; the blackboard made of glass plate still has the disadvantages of being fragile, reflective, and unable to absorb magnetism
