The piezoelectric type electric writing pen for electronic ink display consists of automatic ball-point pen (including refill, shaft and push-button switch) and piezoelectric ceramic, in which the refill and piezoelectric ceramic are placed in the shaft of the pen, said piezoelectric ceramic and the refill can be up-and-down contacted and connected. When it is used for writing, the refill can be sprung out, and can be used for writing on the electronic paper lightly, said repill can apply a pressure to the piezoelectric ceramic, so that two ends of the piezoelectric ceramic can produce positive and negative charges, can be static charges can be collected on the ball-point of the refill to excite a static electric field with 20-200V near by ball-point. |
