Good for Vision

Techie Multi-function Teaching Board was designed base on twilight quantum theory. Its beige surface provides a comfortable visual experience. Beige color has chromatography wavelength between 550 and 770 nm which is the best receptive color to human retina. It helps to reduce eye fatigue and improve eye recognition capability. Its beige color design provides the best visual environment that helps protect eyesight and prevent myopia.

 

 

It can be directly used as a projection screen

A typical classroom has blackboard or whiteboard and a projection screen. The projection screen is installed separately either above or beside the blackboard or whiteboard. It is inconvenient to use such system. Our teaching board combines the functions of both projection screen and whiteboard. Presenter can write directly on projection area. This innovative product maximizes the utilization of the classroom resources.
