1、原(yuan)理(li)不同

被動(dong)式電容筆：筆尖的(de)足夠觸控面積(ji)能夠吸取足夠多的(de)電信(xin)號(hao)(hao)，模(mo)擬手指，通過導電筆桿(gan)將這個電信(xin)號(hao)(hao)傳遞(di)到手上。

主動式電(dian)(dian)(dian)容筆(bi)：一個(ge)像(xiang)泵(beng)一樣的電(dian)(dian)(dian)路主動地把更多的電(dian)(dian)(dian)流(liu)吸取上來，需要電(dian)(dian)(dian)池（無論是充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池還是標準可(ke)更換電(dian)(dian)(dian)池）。

2、精度不同

主(zhu)動(dong)(dong)式(shi)電(dian)容(rong)(rong)筆(bi)(bi)的(de)筆(bi)(bi)尖(jian)比被(bei)動(dong)(dong)式(shi)電(dian)容(rong)(rong)筆(bi)(bi)的(de)筆(bi)(bi)尖(jian)細(xi)，所以導致了主(zhu)動(dong)(dong)式(shi)電(dian)容(rong)(rong)筆(bi)(bi)比被(bei)動(dong)(dong)式(shi)電(dian)容(rong)(rong)筆(bi)(bi)精(jing)度高，不(bu)過在主(zhu)動(dong)(dong)式(shi)電(dian)容(rong)(rong)筆(bi)(bi)電(dian)量(liang)為零的(de)情況(kuang)下就完全不(bu)能使(shi)用(yong)了。

3、筆(bi)尖直徑不同

被動式電容筆：筆尖的直(zhi)徑超過(guo)6mm。

主動式(shi)電容筆：筆尖的(de)直徑小于等于3mm。

4、價格不同

主動(dong)式電(dian)容筆(bi)(bi)通(tong)常比被(bei)動(dong)式電(dian)容筆(bi)(bi)多了內部(bu)的芯片(pian)，結構也更復雜一些(xie)，因此(ci)價格(ge)通(tong)常更貴，被(bei)動(dong)式電(dian)容筆(bi)(bi)可能十幾元到幾十元就能買到，主動(dong)式電(dian)容筆(bi)(bi)要一百(bai)多元甚至五六百(bai)元。
