1、原理不同(tong)

被動式電容筆：筆尖的(de)足(zu)夠(gou)觸控面積能(neng)夠(gou)吸取足(zu)夠(gou)多的(de)電信號，模擬手指，通過導電筆桿將這個電信號傳遞到手上。

主動式(shi)電(dian)容筆：一(yi)個像泵一(yi)樣(yang)的電(dian)路主動地把(ba)更多(duo)的電(dian)流吸取上來，需要電(dian)池(chi)（無論是充電(dian)電(dian)池(chi)還(huan)是標準可更換電(dian)池(chi)）。

2、精度不同

主(zhu)動(dong)式(shi)電(dian)(dian)容(rong)(rong)筆(bi)的筆(bi)尖(jian)比被動(dong)式(shi)電(dian)(dian)容(rong)(rong)筆(bi)的筆(bi)尖(jian)細，所以導(dao)致了(le)主(zhu)動(dong)式(shi)電(dian)(dian)容(rong)(rong)筆(bi)比被動(dong)式(shi)電(dian)(dian)容(rong)(rong)筆(bi)精度高，不(bu)過(guo)在主(zhu)動(dong)式(shi)電(dian)(dian)容(rong)(rong)筆(bi)電(dian)(dian)量為零的情況下(xia)就完全不(bu)能使用了(le)。

3、筆尖直徑(jing)不同

被(bei)動式電容筆：筆尖的直(zhi)徑超過6mm。

主動式電容筆(bi)：筆(bi)尖的直徑小于等于3mm。

4、價格不同

主動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)(bi)通常(chang)比被動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)(bi)多了內部的芯片，結構(gou)也更復雜一些，因(yin)此價格(ge)通常(chang)更貴，被動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)(bi)可能(neng)十幾(ji)元(yuan)(yuan)到幾(ji)十元(yuan)(yuan)就能(neng)買(mai)到，主動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)(bi)要一百多元(yuan)(yuan)甚(shen)至(zhi)五六(liu)百元(yuan)(yuan)。
