一、電容筆和觸控筆的區別

電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)是(shi)利用(yong)(yong)(yong)(yong)導(dao)(dao)體(ti)(ti)材料制作(zuo)(zuo)的(de)(de)具(ju)有(you)(you)的(de)(de)導(dao)(dao)電(dian)(dian)特性，用(yong)(yong)(yong)(yong)來(lai)在(zai)(zai)觸(chu)(chu)(chu)控(kong)(kong)(kong)電(dian)(dian)容(rong)(rong)(rong)式屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)完成人機對(dui)話操作(zuo)(zuo)用(yong)(yong)(yong)(yong)的(de)(de)筆(bi)(bi)，是(shi)利用(yong)(yong)(yong)(yong)導(dao)(dao)體(ti)(ti)材料模仿人體(ti)(ti)（通常(chang)是(shi)手指(zhi)）完成人機對(dui)話一(yi)種(zhong)輔(fu)助裝置。觸(chu)(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)是(shi)一(yi)種(zhong)小筆(bi)(bi)形的(de)(de)工具(ju)，用(yong)(yong)(yong)(yong)來(lai)輸入指(zhi)令到電(dian)(dian)腦屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)、移動設(she)備(bei)、繪圖板等(deng)具(ju)有(you)(you)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)(ping)(ping)的(de)(de)設(she)備(bei)，用(yong)(yong)(yong)(yong)戶可以(yi)通過(guo)觸(chu)(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)點擊觸(chu)(chu)(chu)控(kong)(kong)(kong)屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)來(lai)選取文件或(huo)繪畫。電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)和(he)(he)觸(chu)(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)兩者(zhe)的(de)(de)區別在(zai)(zai)導(dao)(dao)體(ti)(ti)材料、作(zuo)(zuo)用(yong)(yong)(yong)(yong)機制和(he)(he)適(shi)(shi)(shi)用(yong)(yong)(yong)(yong)對(dui)象(xiang)的(de)(de)不同：電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)筆(bi)(bi)頭帶(dai)有(you)(you)靜電(dian)(dian)，電(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)本身(shen)有(you)(you)感應(ying)靜電(dian)(dian)的(de)(de)技術特點，所以(yi)電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)適(shi)(shi)(shi)用(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)；而普通的(de)(de)觸(chu)(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)是(shi)靠(kao)按壓屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)，適(shi)(shi)(shi)用(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)阻屏(ping)(ping)(ping)(ping)(ping)。電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)和(he)(he)觸(chu)(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)哪(na)個好，寫字繪畫用(yong)(yong)(yong)(yong)哪(na)種(zhong)筆(bi)(bi)主要要根據選擇(ze)的(de)(de)產品來(lai)看，不同的(de)(de)屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)(mu)適(shi)(shi)(shi)應(ying)不同的(de)(de)筆(bi)(bi)：觸(chu)(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)主要適(shi)(shi)(shi)用(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)阻屏(ping)(ping)(ping)(ping)(ping)，電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)適(shi)(shi)(shi)用(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)，現在(zai)(zai)的(de)(de)平(ping)板、手機等(deng)設(she)備(bei)基(ji)本上都是(shi)用(yong)(yong)(yong)(yong)的(de)(de)電(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)，因此(ci)一(yi)般現在(zai)(zai)用(yong)(yong)(yong)(yong)電(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)比(bi)較(jiao)多。

二、電容筆是什么平板都可以用嗎

電容筆對于操作平板電腦來說還是比較方便的，尤其是對需要經常在平板上寫寫畫畫的人來說，很多朋友比較關心電容筆的兼容性，其實一般來說，只要是電容屏的產品，電容筆都是通用的，因為電容屏的使用原理是一樣的，電容筆的使用原理也都是一樣，被動式電容筆可以用在所有電容屏產品上，只是效果可能有一些差異。另外，有的品牌的電容筆不是被動電容筆，而是內部有芯片的主動式電容筆，需要藍牙連接才能使用的，這種不一定可以通用，因此建議大家看看自家平板是什么品牌，然后買同品牌的電容筆。購買電容筆的時候，除了注意電容筆品牌外，還要注意考慮電容筆的防誤觸功能(neng)、延(yan)遲、筆尖材(cai)質、續航能(neng)力、有無壓感功能(neng)等方(fang)面。

三、電容筆怎么連接平板

電(dian)(dian)容(rong)筆分為被動式(shi)電(dian)(dian)容(rong)筆和主(zhu)動式(shi)電(dian)(dian)容(rong)筆，被動式(shi)電(dian)(dian)容(rong)筆可(ke)(ke)以(yi)直接(jie)(jie)用，主(zhu)動式(shi)電(dian)(dian)容(rong)筆內(nei)置芯片，需(xu)要連(lian)接(jie)(jie)才能使(shi)用，連(lian)接(jie)(jie)方法很簡單：1、將(jiang)手(shou)(shou)寫筆放在平板(ban)附近，拉(la)下狀態欄，將(jiang)藍(lan)(lan)牙打開，再長按“藍(lan)(lan)牙”，進(jin)入藍(lan)(lan)牙界面(mian)。2、這時(shi)，藍(lan)(lan)牙會自動彈(dan)(dan)出(chu)連(lian)接(jie)(jie)界面(mian)，點(dian)擊“連(lian)接(jie)(jie)”即可(ke)(ke)，如果(guo)沒有(you)彈(dan)(dan)出(chu)，也可(ke)(ke)以(yi)在藍(lan)(lan)牙搜索界面(mian)里(li)找到手(shou)(shou)寫筆的ID，然(ran)后連(lian)接(jie)(jie)。3、連(lian)接(jie)(jie)好后，手(shou)(shou)寫筆就可(ke)(ke)以(yi)使(shi)用了。

四、電容筆是干什么用的

電(dian)(dian)容筆在(zai)最初出現的(de)(de)(de)(de)時候(hou)，較為(wei)普遍地(di)使用(yong)(yong)在(zai)部分帶有觸屏功能(neng)(neng)的(de)(de)(de)(de)手機(ji)上，可(ke)(ke)以(yi)用(yong)(yong)電(dian)(dian)容筆進(jin)行(xing)操作(zuo)(zuo)，用(yong)(yong)于操作(zuo)(zuo)對應的(de)(de)(de)(de)屏幕上方功能(neng)(neng)按鈕，以(yi)達到(dao)使用(yong)(yong)者的(de)(de)(de)(de)目的(de)(de)(de)(de)。由(you)于當時技術(shu)(shu)并不先進(jin)，導致手機(ji)及平板很(hen)多(duo)功能(neng)(neng)未被開(kai)發出來，而(er)使得電(dian)(dian)容筆的(de)(de)(de)(de)用(yong)(yong)途(tu)受到(dao)較大的(de)(de)(de)(de)局限，不過現如(ru)(ru)今(jin)不管是(shi)硬件還是(shi)軟件技術(shu)(shu)都得到(dao)跨越(yue)性的(de)(de)(de)(de)提升，電(dian)(dian)容筆的(de)(de)(de)(de)用(yong)(yong)途(tu)更加廣(guang)泛。現如(ru)(ru)今(jin)，隨著更多(duo)App的(de)(de)(de)(de)較完善(shan)的(de)(de)(de)(de)功能(neng)(neng)開(kai)發，讓電(dian)(dian)容筆的(de)(de)(de)(de)功能(neng)(neng)也(ye)產生質的(de)(de)(de)(de)改變，不再只是(shi)用(yong)(yong)于觸控(kong)操作(zuo)(zuo)這么簡(jian)單。現如(ru)(ru)今(jin)電(dian)(dian)容筆已經(jing)可(ke)(ke)以(yi)直接在(zai)移(yi)動設備，如(ru)(ru)手機(ji)、筆記本、平板等，利用(yong)(yong)APP的(de)(de)(de)(de)功能(neng)(neng)開(kai)展工(gong)作(zuo)(zuo)，比如(ru)(ru)進(jin)行(xing)繪畫、制(zhi)圖、更正或者標注文檔等，也(ye)可(ke)(ke)對相(xiang)關會議或談話現場(chang)進(jin)行(xing)快速記錄(lu)等。

五、電容筆的工作原理

要知道電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)的(de)工作(zuo)原理，首先(xian)要了(le)解(jie)與電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)配套(tao)使(shi)用的(de)電(dian)(dian)(dian)容(rong)(rong)屏(ping)的(de)原理：電(dian)(dian)(dian)容(rong)(rong)屏(ping)是利用人(ren)體(ti)(ti)的(de)電(dian)(dian)(dian)流(liu)(liu)感應工作(zuo)的(de)，電(dian)(dian)(dian)容(rong)(rong)觸(chu)(chu)摸屏(ping)利用人(ren)體(ti)(ti)的(de)電(dian)(dian)(dian)流(liu)(liu)感應進行工作(zuo)，當手指(zhi)(zhi)(zhi)觸(chu)(chu)摸在金屬層上時，由于人(ren)體(ti)(ti)電(dian)(dian)(dian)場、用戶和觸(chu)(chu)控(kong)屏(ping)表(biao)面形(xing)成以(yi)一個(ge)耦(ou)合電(dian)(dian)(dian)容(rong)(rong)，對于高頻電(dian)(dian)(dian)流(liu)(liu)來說，電(dian)(dian)(dian)容(rong)(rong)是直(zhi)接(jie)導體(ti)(ti)，于是手指(zhi)(zhi)(zhi)從接(jie)觸(chu)(chu)點(dian)吸走一個(ge)很小的(de)電(dian)(dian)(dian)流(liu)(liu)。這個(ge)電(dian)(dian)(dian)流(liu)(liu)分別從觸(chu)(chu)控(kong)屏(ping)四(si)角(jiao)上的(de)電(dian)(dian)(dian)極中流(liu)(liu)出，并且流(liu)(liu)經(jing)這四(si)個(ge)電(dian)(dian)(dian)極的(de)電(dian)(dian)(dian)流(liu)(liu)與手指(zhi)(zhi)(zhi)到四(si)角(jiao)的(de)距離成正比，控(kong)制器通(tong)(tong)過(guo)對這四(si)個(ge)電(dian)(dian)(dian)流(liu)(liu)比例的(de)精確計(ji)算(suan)，得出觸(chu)(chu)摸點(dian)的(de)位置信(xin)息。電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)就是通(tong)(tong)過(guo)導體(ti)(ti)模擬人(ren)體(ti)(ti)手指(zhi)(zhi)(zhi)，筆(bi)(bi)尖(jian)觸(chu)(chu)摸電(dian)(dian)(dian)容(rong)(rong)屏(ping)時同樣產(chan)生電(dian)(dian)(dian)流(liu)(liu)，控(kong)制器對電(dian)(dian)(dian)流(liu)(liu)計(ji)算(suan)得出觸(chu)(chu)摸信(xin)息，并完成操作(zuo)。
