一、電容筆和觸控筆的區別

電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)是利用(yong)(yong)導(dao)體(ti)材料(liao)制(zhi)作的(de)(de)(de)具有的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)特性，用(yong)(yong)來在觸(chu)控(kong)(kong)電(dian)(dian)(dian)(dian)(dian)容(rong)式(shi)屏(ping)(ping)(ping)(ping)幕(mu)完成(cheng)人機(ji)對話操作用(yong)(yong)的(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)，是利用(yong)(yong)導(dao)體(ti)材料(liao)模仿人體(ti)（通(tong)常是手指）完成(cheng)人機(ji)對話一(yi)種(zhong)輔助裝置。觸(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)是一(yi)種(zhong)小筆(bi)(bi)(bi)(bi)(bi)形(xing)的(de)(de)(de)工具，用(yong)(yong)來輸入指令到電(dian)(dian)(dian)(dian)(dian)腦屏(ping)(ping)(ping)(ping)幕(mu)、移動設(she)(she)備(bei)、繪圖板等(deng)具有觸(chu)摸屏(ping)(ping)(ping)(ping)的(de)(de)(de)設(she)(she)備(bei)，用(yong)(yong)戶可以通(tong)過觸(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)點(dian)擊觸(chu)控(kong)(kong)屏(ping)(ping)(ping)(ping)幕(mu)來選取文件(jian)或繪畫。電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)和觸(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)兩(liang)者的(de)(de)(de)區(qu)別在導(dao)體(ti)材料(liao)、作用(yong)(yong)機(ji)制(zhi)和適(shi)用(yong)(yong)對象的(de)(de)(de)不同：電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)(bi)頭帶(dai)有靜(jing)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)(ping)(ping)幕(mu)本(ben)身有感應靜(jing)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)技術特點(dian)，所以電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)適(shi)用(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)(ping)(ping)；而普(pu)通(tong)的(de)(de)(de)觸(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)是靠按(an)壓屏(ping)(ping)(ping)(ping)幕(mu)，適(shi)用(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)阻屏(ping)(ping)(ping)(ping)。電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)和觸(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)哪個好，寫字繪畫用(yong)(yong)哪種(zhong)筆(bi)(bi)(bi)(bi)(bi)主要(yao)要(yao)根據選擇(ze)的(de)(de)(de)產品來看(kan)，不同的(de)(de)(de)屏(ping)(ping)(ping)(ping)幕(mu)適(shi)應不同的(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)：觸(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)主要(yao)適(shi)用(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)阻屏(ping)(ping)(ping)(ping)，電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)適(shi)用(yong)(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)(ping)(ping)，現(xian)在的(de)(de)(de)平板、手機(ji)等(deng)設(she)(she)備(bei)基本(ben)上都是用(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)(ping)(ping)，因此一(yi)般(ban)現(xian)在用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)(bi)(bi)(bi)(bi)比(bi)較多(duo)。

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(wai)，還(huan)要注意考慮(lv)電(dian)容(rong)筆的防誤觸功能(neng)、延(yan)遲、筆尖材質(zhi)、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)容(rong)筆(bi)(bi)分為被(bei)動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)和(he)主動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)，被(bei)動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)可(ke)(ke)以(yi)直(zhi)接(jie)用(yong)，主動(dong)(dong)式(shi)電(dian)容(rong)筆(bi)(bi)內置(zhi)芯片，需要連接(jie)才能(neng)使用(yong)，連接(jie)方法很簡單：1、將手寫(xie)筆(bi)(bi)放在平板附(fu)近，拉下狀(zhuang)態(tai)欄，將藍(lan)牙(ya)打開，再長按“藍(lan)牙(ya)”，進入(ru)藍(lan)牙(ya)界面。2、這時，藍(lan)牙(ya)會自動(dong)(dong)彈出(chu)(chu)連接(jie)界面，點擊“連接(jie)”即(ji)可(ke)(ke)，如果沒有彈出(chu)(chu)，也可(ke)(ke)以(yi)在藍(lan)牙(ya)搜(sou)索界面里(li)找到手寫(xie)筆(bi)(bi)的ID，然后(hou)連接(jie)。3、連接(jie)好后(hou)，手寫(xie)筆(bi)(bi)就可(ke)(ke)以(yi)使用(yong)了。

四、電容筆是干什么用的

電(dian)容(rong)(rong)筆(bi)(bi)在(zai)最初出現(xian)(xian)的(de)(de)(de)(de)(de)(de)(de)時(shi)候，較為普遍地(di)使(shi)(shi)用(yong)在(zai)部(bu)分(fen)帶有觸(chu)屏(ping)功(gong)(gong)能(neng)(neng)的(de)(de)(de)(de)(de)(de)(de)手機上，可(ke)(ke)以(yi)用(yong)電(dian)容(rong)(rong)筆(bi)(bi)進行(xing)操(cao)作，用(yong)于操(cao)作對應的(de)(de)(de)(de)(de)(de)(de)屏(ping)幕上方功(gong)(gong)能(neng)(neng)按鈕(niu)，以(yi)達到使(shi)(shi)用(yong)者的(de)(de)(de)(de)(de)(de)(de)目的(de)(de)(de)(de)(de)(de)(de)。由(you)于當時(shi)技術并(bing)不(bu)(bu)先(xian)進，導致手機及平板(ban)很多功(gong)(gong)能(neng)(neng)未被開(kai)發出來(lai)，而使(shi)(shi)得電(dian)容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)(de)(de)用(yong)途受到較大的(de)(de)(de)(de)(de)(de)(de)局限，不(bu)(bu)過現(xian)(xian)如(ru)今(jin)不(bu)(bu)管是硬件還是軟件技術都得到跨越(yue)性的(de)(de)(de)(de)(de)(de)(de)提升，電(dian)容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)(de)(de)用(yong)途更加廣泛。現(xian)(xian)如(ru)今(jin)，隨(sui)著更多App的(de)(de)(de)(de)(de)(de)(de)較完善的(de)(de)(de)(de)(de)(de)(de)功(gong)(gong)能(neng)(neng)開(kai)發，讓電(dian)容(rong)(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)(de)(de)功(gong)(gong)能(neng)(neng)也產生質(zhi)的(de)(de)(de)(de)(de)(de)(de)改變，不(bu)(bu)再只是用(yong)于觸(chu)控操(cao)作這么簡單。現(xian)(xian)如(ru)今(jin)電(dian)容(rong)(rong)筆(bi)(bi)已(yi)經(jing)可(ke)(ke)以(yi)直接在(zai)移動設備，如(ru)手機、筆(bi)(bi)記本、平板(ban)等，利用(yong)APP的(de)(de)(de)(de)(de)(de)(de)功(gong)(gong)能(neng)(neng)開(kai)展工作，比如(ru)進行(xing)繪畫、制圖、更正(zheng)或者標注文檔等，也可(ke)(ke)對相關會議或談話現(xian)(xian)場進行(xing)快速記錄等。

五、電容筆的工作原理

要知(zhi)道電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)的(de)工(gong)作原理，首先要了解(jie)與電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)配套使用(yong)(yong)(yong)的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)屏的(de)原理：電(dian)(dian)(dian)(dian)(dian)容(rong)屏是利用(yong)(yong)(yong)人(ren)體(ti)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)感應(ying)工(gong)作的(de)，電(dian)(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)摸(mo)屏利用(yong)(yong)(yong)人(ren)體(ti)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)感應(ying)進行工(gong)作，當手指(zhi)(zhi)觸(chu)(chu)摸(mo)在金屬(shu)層上時，由(you)于(yu)人(ren)體(ti)電(dian)(dian)(dian)(dian)(dian)場(chang)、用(yong)(yong)(yong)戶和觸(chu)(chu)控屏表面形成(cheng)以一(yi)個(ge)耦合電(dian)(dian)(dian)(dian)(dian)容(rong)，對于(yu)高頻電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)來說，電(dian)(dian)(dian)(dian)(dian)容(rong)是直接導(dao)體(ti)，于(yu)是手指(zhi)(zhi)從接觸(chu)(chu)點吸走一(yi)個(ge)很小的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)。這(zhe)個(ge)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)分(fen)別從觸(chu)(chu)控屏四(si)角上的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)中流(liu)(liu)(liu)(liu)出，并且流(liu)(liu)(liu)(liu)經這(zhe)四(si)個(ge)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)與手指(zhi)(zhi)到四(si)角的(de)距離成(cheng)正比(bi)，控制(zhi)(zhi)器(qi)通(tong)過對這(zhe)四(si)個(ge)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)比(bi)例(li)的(de)精確計算，得出觸(chu)(chu)摸(mo)點的(de)位(wei)置信(xin)(xin)息(xi)。電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)就(jiu)是通(tong)過導(dao)體(ti)模擬人(ren)體(ti)手指(zhi)(zhi)，筆(bi)尖觸(chu)(chu)摸(mo)電(dian)(dian)(dian)(dian)(dian)容(rong)屏時同(tong)樣產(chan)生電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，控制(zhi)(zhi)器(qi)對電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)計算得出觸(chu)(chu)摸(mo)信(xin)(xin)息(xi)，并完成(cheng)操作。
