smart school blackboard.At present, there are three types of copy-type electronic whiteboards, interactive whiteboards and digital touch screens on the market. The interactive whiteboards are divided into electromagnetic, infrared and pressure sensitive types. If you only use it in the discussion, it is enough to choose a copy-type whiteboard; if you need to do multiple demonstrations, you should choose some interactive whiteboards and digital touch screens. Digital touch screens should be used in schools because, in contrast, digital touch screens are the best in transmission speed, safety and aging resistance. In some important units or military departments, because of the shielding, it is advisable to choose a pressure-sensitive electronic whiteboard or digital touch screen with strong anti-interference.
