55Inch LCD 4K UHD Resolution Capacitive Touch Sensor Digital Smart Board Interactive Panel Interact Whiteboard
Capacitive technology which is similar to the latest IPhone/IPad technology for touch screen is now the most advanced technology in Interactive Whiteboard Industry. It is different from and superior to other traditional Interactive Whiteboard (Electromagnetic/Infrared/Optical) technologies and will become the future trend.
Data processing load is 100 times of infrared technology, which results in excellent multi-writing performance, supporting up to 10 different users writing simultaneously. The multi-touch technology results in more dynamic interactions around the contents.
The capacitive film inside the board identifies and locates static electrical capacity of the human body when a person touches the board. As it recognizes only finger touch or capacitive pen touch, any inaccurate touch or writing triggered by the objects on or close to the board can be eliminated.
