一、電容筆和觸控筆的區別

電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)是(shi)利(li)用(yong)導體材(cai)料(liao)(liao)制(zhi)作(zuo)(zuo)的(de)(de)具(ju)(ju)有(you)(you)的(de)(de)導電(dian)(dian)(dian)(dian)特性，用(yong)來(lai)在觸(chu)(chu)控電(dian)(dian)(dian)(dian)容(rong)(rong)式屏(ping)幕(mu)完成人(ren)(ren)機對(dui)話操作(zuo)(zuo)用(yong)的(de)(de)筆(bi)(bi)(bi)，是(shi)利(li)用(yong)導體材(cai)料(liao)(liao)模仿人(ren)(ren)體（通常是(shi)手指）完成人(ren)(ren)機對(dui)話一種輔助裝置。觸(chu)(chu)控筆(bi)(bi)(bi)是(shi)一種小筆(bi)(bi)(bi)形的(de)(de)工具(ju)(ju)，用(yong)來(lai)輸入指令(ling)到電(dian)(dian)(dian)(dian)腦屏(ping)幕(mu)、移動設備、繪圖板等具(ju)(ju)有(you)(you)觸(chu)(chu)摸屏(ping)的(de)(de)設備，用(yong)戶(hu)可以(yi)通過(guo)觸(chu)(chu)控筆(bi)(bi)(bi)點(dian)擊觸(chu)(chu)控屏(ping)幕(mu)來(lai)選取文件(jian)或繪畫。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)和(he)觸(chu)(chu)控筆(bi)(bi)(bi)兩者的(de)(de)區(qu)別在導體材(cai)料(liao)(liao)、作(zuo)(zuo)用(yong)機制(zhi)和(he)適(shi)(shi)用(yong)對(dui)象的(de)(de)不(bu)同：電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)筆(bi)(bi)(bi)頭帶有(you)(you)靜電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)幕(mu)本身有(you)(you)感應靜電(dian)(dian)(dian)(dian)的(de)(de)技術特點(dian)，所以(yi)電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)適(shi)(shi)用(yong)于電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)；而普通的(de)(de)觸(chu)(chu)控筆(bi)(bi)(bi)是(shi)靠按壓(ya)屏(ping)幕(mu)，適(shi)(shi)用(yong)于電(dian)(dian)(dian)(dian)阻(zu)屏(ping)。電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)和(he)觸(chu)(chu)控筆(bi)(bi)(bi)哪個好，寫字繪畫用(yong)哪種筆(bi)(bi)(bi)主要(yao)要(yao)根據選擇的(de)(de)產品來(lai)看(kan)，不(bu)同的(de)(de)屏(ping)幕(mu)適(shi)(shi)應不(bu)同的(de)(de)筆(bi)(bi)(bi)：觸(chu)(chu)控筆(bi)(bi)(bi)主要(yao)適(shi)(shi)用(yong)于電(dian)(dian)(dian)(dian)阻(zu)屏(ping)，電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)適(shi)(shi)用(yong)于電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)，現在的(de)(de)平板、手機等設備基本上都是(shi)用(yong)的(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)，因此一般現在用(yong)電(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)比較多。

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(kao)慮電容筆的防誤(wu)觸功能、延遲、筆尖材質、續航(hang)能力(li)、有無壓感(gan)功能等(deng)方面。

三、電容筆怎么連接平板

電(dian)容(rong)(rong)筆(bi)(bi)(bi)分(fen)為被(bei)動式電(dian)容(rong)(rong)筆(bi)(bi)(bi)和主(zhu)動式電(dian)容(rong)(rong)筆(bi)(bi)(bi)，被(bei)動式電(dian)容(rong)(rong)筆(bi)(bi)(bi)可以直接(jie)用(yong)，主(zhu)動式電(dian)容(rong)(rong)筆(bi)(bi)(bi)內(nei)置芯片，需(xu)要連(lian)接(jie)才能使用(yong)，連(lian)接(jie)方法很(hen)簡單：1、將手寫筆(bi)(bi)(bi)放在平板(ban)附(fu)近，拉下狀態(tai)欄(lan)，將藍牙(ya)打開，再(zai)長按“藍牙(ya)”，進(jin)入藍牙(ya)界(jie)面。2、這時，藍牙(ya)會自動彈出連(lian)接(jie)界(jie)面，點擊(ji)“連(lian)接(jie)”即可，如果沒有彈出，也(ye)可以在藍牙(ya)搜索界(jie)面里找到手寫筆(bi)(bi)(bi)的ID，然后連(lian)接(jie)。3、連(lian)接(jie)好后，手寫筆(bi)(bi)(bi)就(jiu)可以使用(yong)了。

四、電容筆是干什么用的

電(dian)(dian)容(rong)筆在最初出現(xian)(xian)(xian)的(de)(de)時候，較為普遍地使(shi)用(yong)(yong)(yong)在部分帶有(you)觸屏功(gong)(gong)能(neng)的(de)(de)手機(ji)(ji)上，可以(yi)(yi)用(yong)(yong)(yong)電(dian)(dian)容(rong)筆進行(xing)操(cao)作(zuo)，用(yong)(yong)(yong)于操(cao)作(zuo)對應的(de)(de)屏幕上方功(gong)(gong)能(neng)按(an)鈕，以(yi)(yi)達到使(shi)用(yong)(yong)(yong)者的(de)(de)目的(de)(de)。由于當時技(ji)術(shu)并不先進，導致手機(ji)(ji)及(ji)平板很多功(gong)(gong)能(neng)未被開發出來，而使(shi)得(de)電(dian)(dian)容(rong)筆的(de)(de)用(yong)(yong)(yong)途受到較大(da)的(de)(de)局限，不過現(xian)(xian)(xian)如(ru)今不管(guan)是硬件還是軟件技(ji)術(shu)都得(de)到跨(kua)越性的(de)(de)提(ti)升，電(dian)(dian)容(rong)筆的(de)(de)用(yong)(yong)(yong)途更(geng)加(jia)廣(guang)泛(fan)。現(xian)(xian)(xian)如(ru)今，隨著(zhu)更(geng)多App的(de)(de)較完(wan)善的(de)(de)功(gong)(gong)能(neng)開發，讓電(dian)(dian)容(rong)筆的(de)(de)功(gong)(gong)能(neng)也產生(sheng)質的(de)(de)改變，不再只是用(yong)(yong)(yong)于觸控操(cao)作(zuo)這么簡單。現(xian)(xian)(xian)如(ru)今電(dian)(dian)容(rong)筆已經可以(yi)(yi)直接在移動設備，如(ru)手機(ji)(ji)、筆記本、平板等(deng)，利用(yong)(yong)(yong)APP的(de)(de)功(gong)(gong)能(neng)開展(zhan)工作(zuo)，比如(ru)進行(xing)繪(hui)畫、制圖(tu)、更(geng)正(zheng)或者標注文檔等(deng)，也可對相關(guan)會(hui)議或談話(hua)現(xian)(xian)(xian)場進行(xing)快(kuai)速記錄等(deng)。

五、電容筆的工作原理

要(yao)知(zhi)道電(dian)(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)工(gong)作原(yuan)理(li)，首先(xian)要(yao)了解與電(dian)(dian)(dian)(dian)容(rong)(rong)筆配套使用(yong)(yong)(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)的(de)(de)(de)原(yuan)理(li)：電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)是(shi)利(li)用(yong)(yong)(yong)人(ren)(ren)體(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)感(gan)應工(gong)作的(de)(de)(de)，電(dian)(dian)(dian)(dian)容(rong)(rong)觸摸(mo)(mo)屏(ping)利(li)用(yong)(yong)(yong)人(ren)(ren)體(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)感(gan)應進(jin)行工(gong)作，當(dang)手(shou)指(zhi)(zhi)觸摸(mo)(mo)在金(jin)屬層上時，由于(yu)人(ren)(ren)體(ti)電(dian)(dian)(dian)(dian)場(chang)、用(yong)(yong)(yong)戶和觸控(kong)屏(ping)表面形成(cheng)以一(yi)個耦(ou)合電(dian)(dian)(dian)(dian)容(rong)(rong)，對于(yu)高頻電(dian)(dian)(dian)(dian)流(liu)(liu)來(lai)說，電(dian)(dian)(dian)(dian)容(rong)(rong)是(shi)直(zhi)接導(dao)體(ti)，于(yu)是(shi)手(shou)指(zhi)(zhi)從(cong)接觸點吸走一(yi)個很小的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)。這個電(dian)(dian)(dian)(dian)流(liu)(liu)分別從(cong)觸控(kong)屏(ping)四(si)角(jiao)(jiao)上的(de)(de)(de)電(dian)(dian)(dian)(dian)極中流(liu)(liu)出(chu)，并(bing)且流(liu)(liu)經這四(si)個電(dian)(dian)(dian)(dian)極的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)與手(shou)指(zhi)(zhi)到四(si)角(jiao)(jiao)的(de)(de)(de)距(ju)離成(cheng)正比，控(kong)制器通過對這四(si)個電(dian)(dian)(dian)(dian)流(liu)(liu)比例的(de)(de)(de)精確計(ji)算，得出(chu)觸摸(mo)(mo)點的(de)(de)(de)位置(zhi)信息。電(dian)(dian)(dian)(dian)容(rong)(rong)筆就是(shi)通過導(dao)體(ti)模擬人(ren)(ren)體(ti)手(shou)指(zhi)(zhi)，筆尖觸摸(mo)(mo)電(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)時同樣產生電(dian)(dian)(dian)(dian)流(liu)(liu)，控(kong)制器對電(dian)(dian)(dian)(dian)流(liu)(liu)計(ji)算得出(chu)觸摸(mo)(mo)信息，并(bing)完成(cheng)操作。
