一、電容筆和觸控筆的區別

電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)是(shi)(shi)利用(yong)(yong)導(dao)體材料制(zhi)作的(de)(de)具有的(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)(dian)特性，用(yong)(yong)來在觸(chu)控(kong)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)式屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)完成人機對(dui)話操作用(yong)(yong)的(de)(de)筆(bi)(bi)(bi)，是(shi)(shi)利用(yong)(yong)導(dao)體材料模(mo)仿人體（通常(chang)是(shi)(shi)手指）完成人機對(dui)話一(yi)種(zhong)輔助裝置。觸(chu)控(kong)筆(bi)(bi)(bi)是(shi)(shi)一(yi)種(zhong)小筆(bi)(bi)(bi)形的(de)(de)工具，用(yong)(yong)來輸入指令到電(dian)(dian)(dian)(dian)(dian)(dian)腦屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)、移動設(she)(she)備、繪圖板等(deng)具有觸(chu)摸屏(ping)(ping)(ping)(ping)(ping)的(de)(de)設(she)(she)備，用(yong)(yong)戶可以通過(guo)觸(chu)控(kong)筆(bi)(bi)(bi)點(dian)擊(ji)觸(chu)控(kong)屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)來選取文件或(huo)繪畫。電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)和觸(chu)控(kong)筆(bi)(bi)(bi)兩(liang)者的(de)(de)區(qu)別在導(dao)體材料、作用(yong)(yong)機制(zhi)和適(shi)用(yong)(yong)對(dui)象的(de)(de)不(bu)(bu)同(tong)：電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)筆(bi)(bi)(bi)頭帶有靜電(dian)(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)本(ben)身有感應靜電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)技術特點(dian)，所以電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)適(shi)用(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)；而普通的(de)(de)觸(chu)控(kong)筆(bi)(bi)(bi)是(shi)(shi)靠按(an)壓屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)，適(shi)用(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)阻屏(ping)(ping)(ping)(ping)(ping)。電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)和觸(chu)控(kong)筆(bi)(bi)(bi)哪個好(hao)，寫字(zi)繪畫用(yong)(yong)哪種(zhong)筆(bi)(bi)(bi)主(zhu)要(yao)要(yao)根據(ju)選擇的(de)(de)產品來看(kan)，不(bu)(bu)同(tong)的(de)(de)屏(ping)(ping)(ping)(ping)(ping)幕(mu)(mu)適(shi)應不(bu)(bu)同(tong)的(de)(de)筆(bi)(bi)(bi)：觸(chu)控(kong)筆(bi)(bi)(bi)主(zhu)要(yao)適(shi)用(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)阻屏(ping)(ping)(ping)(ping)(ping)，電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)適(shi)用(yong)(yong)于(yu)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)，現在的(de)(de)平板、手機等(deng)設(she)(she)備基本(ben)上(shang)都是(shi)(shi)用(yong)(yong)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)(ping)，因(yin)此(ci)一(yi)般現在用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(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，還要注意考慮電容筆的防(fang)誤觸(chu)功能(neng)、延遲、筆尖材(cai)質、續航(hang)能(neng)力、有無壓感功能(neng)等方面。

三、電容筆怎么連接平板

電容筆(bi)(bi)(bi)分為(wei)被動(dong)(dong)式電容筆(bi)(bi)(bi)和主動(dong)(dong)式電容筆(bi)(bi)(bi)，被動(dong)(dong)式電容筆(bi)(bi)(bi)可(ke)(ke)以直接(jie)(jie)用，主動(dong)(dong)式電容筆(bi)(bi)(bi)內置芯(xin)片，需要連(lian)接(jie)(jie)才能使(shi)用，連(lian)接(jie)(jie)方(fang)法很簡單：1、將手(shou)寫(xie)(xie)筆(bi)(bi)(bi)放在平板附近，拉下狀態(tai)欄，將藍(lan)(lan)牙打(da)開，再長按“藍(lan)(lan)牙”，進入藍(lan)(lan)牙界面。2、這時，藍(lan)(lan)牙會自動(dong)(dong)彈(dan)出連(lian)接(jie)(jie)界面，點擊“連(lian)接(jie)(jie)”即可(ke)(ke)，如果沒有(you)彈(dan)出，也可(ke)(ke)以在藍(lan)(lan)牙搜(sou)索(suo)界面里(li)找到手(shou)寫(xie)(xie)筆(bi)(bi)(bi)的(de)ID，然后連(lian)接(jie)(jie)。3、連(lian)接(jie)(jie)好后，手(shou)寫(xie)(xie)筆(bi)(bi)(bi)就可(ke)(ke)以使(shi)用了。

四、電容筆是干什么用的

電容(rong)(rong)(rong)筆(bi)在最初出現(xian)的(de)(de)(de)(de)時(shi)候，較為普遍地使用(yong)(yong)在部分帶有觸屏(ping)功(gong)(gong)能(neng)的(de)(de)(de)(de)手(shou)機上(shang)(shang)，可以(yi)用(yong)(yong)電容(rong)(rong)(rong)筆(bi)進行操作(zuo)(zuo)，用(yong)(yong)于操作(zuo)(zuo)對應的(de)(de)(de)(de)屏(ping)幕(mu)上(shang)(shang)方(fang)功(gong)(gong)能(neng)按鈕，以(yi)達到使用(yong)(yong)者(zhe)的(de)(de)(de)(de)目的(de)(de)(de)(de)。由于當(dang)時(shi)技術并(bing)不(bu)先進，導致手(shou)機及平(ping)板(ban)很多(duo)功(gong)(gong)能(neng)未被開發出來，而使得電容(rong)(rong)(rong)筆(bi)的(de)(de)(de)(de)用(yong)(yong)途受到較大的(de)(de)(de)(de)局(ju)限，不(bu)過現(xian)如今(jin)(jin)不(bu)管(guan)是(shi)硬件還是(shi)軟件技術都得到跨越性(xing)的(de)(de)(de)(de)提升(sheng)，電容(rong)(rong)(rong)筆(bi)的(de)(de)(de)(de)用(yong)(yong)途更加廣泛(fan)。現(xian)如今(jin)(jin)，隨(sui)著更多(duo)App的(de)(de)(de)(de)較完(wan)善的(de)(de)(de)(de)功(gong)(gong)能(neng)開發，讓電容(rong)(rong)(rong)筆(bi)的(de)(de)(de)(de)功(gong)(gong)能(neng)也產生(sheng)質的(de)(de)(de)(de)改變，不(bu)再(zai)只是(shi)用(yong)(yong)于觸控操作(zuo)(zuo)這么簡單。現(xian)如今(jin)(jin)電容(rong)(rong)(rong)筆(bi)已(yi)經(jing)可以(yi)直接在移(yi)動設備，如手(shou)機、筆(bi)記本、平(ping)板(ban)等(deng)，利(li)用(yong)(yong)APP的(de)(de)(de)(de)功(gong)(gong)能(neng)開展工(gong)作(zuo)(zuo)，比如進行繪畫、制(zhi)圖、更正(zheng)或(huo)者(zhe)標注文檔等(deng)，也可對相關會議或(huo)談話現(xian)場進行快(kuai)速記錄等(deng)。

五、電容筆的工作原理

要知道電(dian)(dian)容筆(bi)的(de)(de)(de)工(gong)作(zuo)(zuo)原(yuan)(yuan)理(li)，首先要了解與(yu)電(dian)(dian)容筆(bi)配套使用的(de)(de)(de)電(dian)(dian)容屏(ping)(ping)的(de)(de)(de)原(yuan)(yuan)理(li)：電(dian)(dian)容屏(ping)(ping)是(shi)利(li)(li)用人體(ti)的(de)(de)(de)電(dian)(dian)流(liu)(liu)(liu)感應工(gong)作(zuo)(zuo)的(de)(de)(de)，電(dian)(dian)容觸(chu)(chu)(chu)(chu)摸(mo)(mo)屏(ping)(ping)利(li)(li)用人體(ti)的(de)(de)(de)電(dian)(dian)流(liu)(liu)(liu)感應進行工(gong)作(zuo)(zuo)，當手指(zhi)觸(chu)(chu)(chu)(chu)摸(mo)(mo)在(zai)金屬層上時，由于(yu)人體(ti)電(dian)(dian)場、用戶和(he)觸(chu)(chu)(chu)(chu)控(kong)屏(ping)(ping)表面形成以一個(ge)耦合電(dian)(dian)容，對于(yu)高(gao)頻電(dian)(dian)流(liu)(liu)(liu)來說，電(dian)(dian)容是(shi)直接導體(ti)，于(yu)是(shi)手指(zhi)從接觸(chu)(chu)(chu)(chu)點(dian)吸走(zou)一個(ge)很小(xiao)的(de)(de)(de)電(dian)(dian)流(liu)(liu)(liu)。這個(ge)電(dian)(dian)流(liu)(liu)(liu)分別從觸(chu)(chu)(chu)(chu)控(kong)屏(ping)(ping)四(si)(si)角上的(de)(de)(de)電(dian)(dian)極中流(liu)(liu)(liu)出，并且流(liu)(liu)(liu)經這四(si)(si)個(ge)電(dian)(dian)極的(de)(de)(de)電(dian)(dian)流(liu)(liu)(liu)與(yu)手指(zhi)到四(si)(si)角的(de)(de)(de)距(ju)離成正比，控(kong)制器通(tong)過(guo)對這四(si)(si)個(ge)電(dian)(dian)流(liu)(liu)(liu)比例的(de)(de)(de)精確計算，得出觸(chu)(chu)(chu)(chu)摸(mo)(mo)點(dian)的(de)(de)(de)位置信息。電(dian)(dian)容筆(bi)就是(shi)通(tong)過(guo)導體(ti)模擬人體(ti)手指(zhi)，筆(bi)尖觸(chu)(chu)(chu)(chu)摸(mo)(mo)電(dian)(dian)容屏(ping)(ping)時同(tong)樣產生電(dian)(dian)流(liu)(liu)(liu)，控(kong)制器對電(dian)(dian)流(liu)(liu)(liu)計算得出觸(chu)(chu)(chu)(chu)摸(mo)(mo)信息，并完(wan)成操(cao)作(zuo)(zuo)。
