Hardware features:
1).Self-Adaption Pen
Generally it produces best results when the electronic pen is vertical 90 degrees to whiteboard.Based on this,the electronic pen of NHboard can work when the inclination degree is within 60.
2)Separation between whiteboard and control card.
All the plate circuit and control circuit have been installed in a small box outside the whiteboard,which is convenient to dismantle and maintain.(Patent No:200910132472
.1)
3).Capacity Charge Electronic Pen
We newly developed capacity charge electronic pen,environmental green,no need battery,save power and energy.
4).Promote respondse speed.
Adopting the quick respondse loop dynanmic tracing technologyto promote the speed of writing and make sure that writing keep pace with the pen simultaneously. 
5).Upscale Film
NHboards adopt state-of-art PET film,ensure 300,000 times writing repeatedly no
Defeat,which is durable to use,support whiteboard pen writing,easily clean with the wet cloth,comfortable with your eyes,anti-glare,wear-proof.(patent No:200910132473
.1)

6).Strong Anti-interference Board and High Impact Resistance Ability
All the NHboards were added one anti-interference shielding layer,which can effectively avoid the signal interference outside.Unlike polycarbonate panel of other
Whiteboards,all the NHboards contain a aluminum-plastic panel which have a high
Impact resistance.
