一、電容筆和觸控筆的區別

電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)是(shi)(shi)利用(yong)(yong)(yong)(yong)(yong)導(dao)體材料(liao)制作(zuo)(zuo)(zuo)的(de)(de)(de)具(ju)有(you)的(de)(de)(de)導(dao)電(dian)(dian)特性，用(yong)(yong)(yong)(yong)(yong)來在觸(chu)控(kong)電(dian)(dian)容(rong)(rong)(rong)(rong)式屏(ping)幕(mu)完(wan)成人機對(dui)話(hua)操作(zuo)(zuo)(zuo)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)筆(bi)(bi)(bi)，是(shi)(shi)利用(yong)(yong)(yong)(yong)(yong)導(dao)體材料(liao)模仿人體（通(tong)常是(shi)(shi)手(shou)指(zhi)）完(wan)成人機對(dui)話(hua)一種輔(fu)助(zhu)裝置。觸(chu)控(kong)筆(bi)(bi)(bi)是(shi)(shi)一種小筆(bi)(bi)(bi)形的(de)(de)(de)工(gong)具(ju)，用(yong)(yong)(yong)(yong)(yong)來輸(shu)入指(zhi)令到(dao)電(dian)(dian)腦(nao)屏(ping)幕(mu)、移動設備、繪圖板(ban)等具(ju)有(you)觸(chu)摸屏(ping)的(de)(de)(de)設備，用(yong)(yong)(yong)(yong)(yong)戶(hu)可以通(tong)過觸(chu)控(kong)筆(bi)(bi)(bi)點(dian)擊(ji)觸(chu)控(kong)屏(ping)幕(mu)來選取文件或繪畫。電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)和(he)觸(chu)控(kong)筆(bi)(bi)(bi)兩者的(de)(de)(de)區(qu)別在導(dao)體材料(liao)、作(zuo)(zuo)(zuo)用(yong)(yong)(yong)(yong)(yong)機制和(he)適用(yong)(yong)(yong)(yong)(yong)對(dui)象的(de)(de)(de)不(bu)(bu)同(tong)(tong)：電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)筆(bi)(bi)(bi)頭帶有(you)靜(jing)電(dian)(dian)，電(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)幕(mu)本身有(you)感應靜(jing)電(dian)(dian)的(de)(de)(de)技術(shu)特點(dian)，所以電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)適用(yong)(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)；而普通(tong)的(de)(de)(de)觸(chu)控(kong)筆(bi)(bi)(bi)是(shi)(shi)靠(kao)按壓(ya)屏(ping)幕(mu)，適用(yong)(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)阻屏(ping)。電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)和(he)觸(chu)控(kong)筆(bi)(bi)(bi)哪個好，寫字繪畫用(yong)(yong)(yong)(yong)(yong)哪種筆(bi)(bi)(bi)主(zhu)要要根據(ju)選擇的(de)(de)(de)產品來看，不(bu)(bu)同(tong)(tong)的(de)(de)(de)屏(ping)幕(mu)適應不(bu)(bu)同(tong)(tong)的(de)(de)(de)筆(bi)(bi)(bi)：觸(chu)控(kong)筆(bi)(bi)(bi)主(zhu)要適用(yong)(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)阻屏(ping)，電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)適用(yong)(yong)(yong)(yong)(yong)于(yu)電(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)，現在的(de)(de)(de)平(ping)板(ban)、手(shou)機等設備基(ji)本上都是(shi)(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)電(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)，因此一般現在用(yong)(yong)(yong)(yong)(yong)電(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)比較(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(huan)要注意考慮(lv)電容筆的防誤觸功(gong)能、延遲、筆尖材(cai)質、續航能力(li)、有(you)無壓感(gan)功(gong)能等(deng)方面。

三、電容筆怎么連接平板

電(dian)(dian)容(rong)筆(bi)分(fen)為被動(dong)式(shi)電(dian)(dian)容(rong)筆(bi)和(he)主動(dong)式(shi)電(dian)(dian)容(rong)筆(bi)，被動(dong)式(shi)電(dian)(dian)容(rong)筆(bi)可(ke)以(yi)直接(jie)用，主動(dong)式(shi)電(dian)(dian)容(rong)筆(bi)內置(zhi)芯片，需要連(lian)接(jie)才(cai)能使(shi)用，連(lian)接(jie)方法很簡(jian)單：1、將手寫(xie)筆(bi)放在(zai)平板附近，拉下狀態欄，將藍(lan)牙(ya)打開，再長按(an)“藍(lan)牙(ya)”，進入藍(lan)牙(ya)界(jie)面(mian)。2、這時，藍(lan)牙(ya)會(hui)自動(dong)彈(dan)出(chu)連(lian)接(jie)界(jie)面(mian)，點(dian)擊(ji)“連(lian)接(jie)”即可(ke)，如果(guo)沒有彈(dan)出(chu)，也可(ke)以(yi)在(zai)藍(lan)牙(ya)搜(sou)索界(jie)面(mian)里找到(dao)手寫(xie)筆(bi)的ID，然后連(lian)接(jie)。3、連(lian)接(jie)好后，手寫(xie)筆(bi)就可(ke)以(yi)使(shi)用了(le)。

四、電容筆是干什么用的

電容(rong)(rong)筆(bi)(bi)在(zai)(zai)最初出現(xian)的(de)(de)(de)(de)(de)時(shi)候(hou)，較為普(pu)遍地使用(yong)在(zai)(zai)部(bu)分帶有觸屏功(gong)(gong)能(neng)的(de)(de)(de)(de)(de)手機上，可(ke)以(yi)用(yong)電容(rong)(rong)筆(bi)(bi)進行(xing)(xing)操作，用(yong)于操作對應的(de)(de)(de)(de)(de)屏幕(mu)上方(fang)功(gong)(gong)能(neng)按鈕，以(yi)達(da)到(dao)使用(yong)者的(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)。由于當時(shi)技(ji)術并不先進，導(dao)致手機及(ji)平(ping)(ping)板很多(duo)功(gong)(gong)能(neng)未被開發(fa)出來，而使得(de)電容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)用(yong)途受(shou)到(dao)較大的(de)(de)(de)(de)(de)局限(xian)，不過現(xian)如今(jin)不管(guan)是(shi)(shi)硬件(jian)還是(shi)(shi)軟件(jian)技(ji)術都(dou)得(de)到(dao)跨越性(xing)的(de)(de)(de)(de)(de)提升，電容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)用(yong)途更加廣泛。現(xian)如今(jin)，隨著更多(duo)App的(de)(de)(de)(de)(de)較完善的(de)(de)(de)(de)(de)功(gong)(gong)能(neng)開發(fa)，讓電容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)功(gong)(gong)能(neng)也產生質的(de)(de)(de)(de)(de)改變，不再只是(shi)(shi)用(yong)于觸控(kong)操作這么簡單(dan)。現(xian)如今(jin)電容(rong)(rong)筆(bi)(bi)已經可(ke)以(yi)直接在(zai)(zai)移動設(she)備，如手機、筆(bi)(bi)記(ji)本(ben)、平(ping)(ping)板等，利用(yong)APP的(de)(de)(de)(de)(de)功(gong)(gong)能(neng)開展(zhan)工作，比(bi)如進行(xing)(xing)繪畫(hua)、制圖(tu)、更正或(huo)者標注文檔等，也可(ke)對相關會議(yi)或(huo)談話現(xian)場進行(xing)(xing)快(kuai)速記(ji)錄等。

五、電容筆的工作原理

要(yao)知道(dao)電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)的工作原理，首先要(yao)了解與電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)配套(tao)使(shi)用的電(dian)(dian)(dian)(dian)容(rong)(rong)屏的原理：電(dian)(dian)(dian)(dian)容(rong)(rong)屏是利(li)(li)用人體(ti)(ti)的電(dian)(dian)(dian)(dian)流感應工作的，電(dian)(dian)(dian)(dian)容(rong)(rong)觸摸(mo)(mo)屏利(li)(li)用人體(ti)(ti)的電(dian)(dian)(dian)(dian)流感應進行工作，當手(shou)指(zhi)觸摸(mo)(mo)在金屬層上時，由于人體(ti)(ti)電(dian)(dian)(dian)(dian)場(chang)、用戶和(he)觸控(kong)屏表面(mian)形成(cheng)以一個耦合電(dian)(dian)(dian)(dian)容(rong)(rong)，對于高頻電(dian)(dian)(dian)(dian)流來說，電(dian)(dian)(dian)(dian)容(rong)(rong)是直接(jie)(jie)導體(ti)(ti)，于是手(shou)指(zhi)從接(jie)(jie)觸點(dian)吸走一個很小的電(dian)(dian)(dian)(dian)流。這(zhe)個電(dian)(dian)(dian)(dian)流分(fen)別從觸控(kong)屏四(si)角上的電(dian)(dian)(dian)(dian)極中流出，并且流經這(zhe)四(si)個電(dian)(dian)(dian)(dian)極的電(dian)(dian)(dian)(dian)流與手(shou)指(zhi)到四(si)角的距(ju)離成(cheng)正(zheng)比，控(kong)制器通過對這(zhe)四(si)個電(dian)(dian)(dian)(dian)流比例的精確計算(suan)，得(de)出觸摸(mo)(mo)點(dian)的位置信(xin)息。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)就(jiu)是通過導體(ti)(ti)模擬人體(ti)(ti)手(shou)指(zhi)，筆(bi)尖觸摸(mo)(mo)電(dian)(dian)(dian)(dian)容(rong)(rong)屏時同樣產生電(dian)(dian)(dian)(dian)流，控(kong)制器對電(dian)(dian)(dian)(dian)流計算(suan)得(de)出觸摸(mo)(mo)信(xin)息，并完成(cheng)操作。
