Touchable LCD conbination with greenboard have the same function as interactive whiteboard but can without projector.
1.Touchable LCD conbination with greenboard
The LCD can touched by finger It can be applied directly in the classroom teaching, business meeting and various kinds of military command system. infraed Technology adopts high precision, highly anti-light infrared location technology, combines excellent functions of various kind of interactive whiteboard and develops software by themselves for infrared interactive whiteboard. You can write on it directly with any non-transparent objects. It is easy to use and to learn, even you needn't to be trained before you use the WATCH software.
Also Can write by markers
Certificate: CE,FCC,ROHS approve
