一、電容筆和觸控筆的區別
電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)是(shi)(shi)利(li)用(yong)(yong)(yong)導(dao)(dao)體(ti)(ti)材(cai)料(liao)(liao)制作(zuo)(zuo)的(de)(de)具有(you)(you)的(de)(de)導(dao)(dao)電(dian)(dian)(dian)特性，用(yong)(yong)(yong)來(lai)(lai)(lai)在(zai)觸(chu)控(kong)(kong)(kong)電(dian)(dian)(dian)容(rong)(rong)式屏(ping)(ping)(ping)幕(mu)(mu)完(wan)成人機(ji)對(dui)(dui)話(hua)操作(zuo)(zuo)用(yong)(yong)(yong)的(de)(de)筆(bi)(bi)(bi)(bi)，是(shi)(shi)利(li)用(yong)(yong)(yong)導(dao)(dao)體(ti)(ti)材(cai)料(liao)(liao)模仿人體(ti)(ti)（通(tong)(tong)常是(shi)(shi)手指）完(wan)成人機(ji)對(dui)(dui)話(hua)一(yi)種(zhong)輔助裝置(zhi)。觸(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)是(shi)(shi)一(yi)種(zhong)小筆(bi)(bi)(bi)(bi)形的(de)(de)工具，用(yong)(yong)(yong)來(lai)(lai)(lai)輸入指令到電(dian)(dian)(dian)腦(nao)屏(ping)(ping)(ping)幕(mu)(mu)、移(yi)動設(she)(she)備、繪(hui)(hui)(hui)圖(tu)板等具有(you)(you)觸(chu)摸屏(ping)(ping)(ping)的(de)(de)設(she)(she)備，用(yong)(yong)(yong)戶可以(yi)通(tong)(tong)過觸(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)點擊觸(chu)控(kong)(kong)(kong)屏(ping)(ping)(ping)幕(mu)(mu)來(lai)(lai)(lai)選取文件或(huo)繪(hui)(hui)(hui)畫。電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)和觸(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)兩者的(de)(de)區別(bie)在(zai)導(dao)(dao)體(ti)(ti)材(cai)料(liao)(liao)、作(zuo)(zuo)用(yong)(yong)(yong)機(ji)制和適(shi)用(yong)(yong)(yong)對(dui)(dui)象(xiang)的(de)(de)不(bu)同：電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)頭帶有(you)(you)靜電(dian)(dian)(dian)，電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)幕(mu)(mu)本(ben)身(shen)有(you)(you)感(gan)應(ying)靜電(dian)(dian)(dian)的(de)(de)技術特點，所以(yi)電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)；而(er)普通(tong)(tong)的(de)(de)觸(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)是(shi)(shi)靠按(an)壓屏(ping)(ping)(ping)幕(mu)(mu)，適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)阻屏(ping)(ping)(ping)。電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)和觸(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)哪個好，寫字繪(hui)(hui)(hui)畫用(yong)(yong)(yong)哪種(zhong)筆(bi)(bi)(bi)(bi)主要要根據選擇的(de)(de)產品來(lai)(lai)(lai)看，不(bu)同的(de)(de)屏(ping)(ping)(ping)幕(mu)(mu)適(shi)應(ying)不(bu)同的(de)(de)筆(bi)(bi)(bi)(bi)：觸(chu)控(kong)(kong)(kong)筆(bi)(bi)(bi)(bi)主要適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)阻屏(ping)(ping)(ping)，電(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)(bi)(bi)適(shi)用(yong)(yong)(yong)于電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)，現在(zai)的(de)(de)平板、手機(ji)等設(she)(she)備基(ji)本(ben)上(shang)都是(shi)(shi)用(yong)(yong)(yong)的(de)(de)電(dian)(dian)(dian)容(rong)(rong)屏(ping)(ping)(ping)，因此(ci)一(yi)般現在(zai)用(yong)(yong)(yong)電(dian)(dian)(dian)容(rong)(rong)筆(bi)(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(wai)，還要(yao)注意考慮(lv)電容筆的防誤(wu)觸功(gong)能、延遲、筆尖(jian)材質(zhi)、續航(hang)能力(li)、有無壓感功(gong)能等方面。
三、電容筆怎么連接平板
電容(rong)筆(bi)分為被動(dong)式(shi)電容(rong)筆(bi)和主動(dong)式(shi)電容(rong)筆(bi)，被動(dong)式(shi)電容(rong)筆(bi)可(ke)(ke)以直接用(yong)，主動(dong)式(shi)電容(rong)筆(bi)內置芯片，需要(yao)連(lian)接才能使(shi)用(yong)，連(lian)接方法很(hen)簡單：1、將手寫(xie)(xie)筆(bi)放在平板附近，拉下狀態欄(lan)，將藍(lan)(lan)牙(ya)打開，再長按“藍(lan)(lan)牙(ya)”，進入(ru)藍(lan)(lan)牙(ya)界(jie)面。2、這時(shi)，藍(lan)(lan)牙(ya)會自動(dong)彈(dan)出連(lian)接界(jie)面，點擊“連(lian)接”即可(ke)(ke)，如果沒(mei)有彈(dan)出，也可(ke)(ke)以在藍(lan)(lan)牙(ya)搜索界(jie)面里找到(dao)手寫(xie)(xie)筆(bi)的ID，然后(hou)連(lian)接。3、連(lian)接好后(hou)，手寫(xie)(xie)筆(bi)就(jiu)可(ke)(ke)以使(shi)用(yong)了。
四、電容筆是干什么用的
電(dian)(dian)容筆(bi)在最初出現的(de)時(shi)候(hou)，較(jiao)為普遍(bian)地使(shi)用(yong)(yong)在部分帶有觸(chu)屏功(gong)(gong)能的(de)手(shou)(shou)機上，可以用(yong)(yong)電(dian)(dian)容筆(bi)進行(xing)操作(zuo)(zuo)，用(yong)(yong)于(yu)操作(zuo)(zuo)對(dui)應的(de)屏幕上方功(gong)(gong)能按鈕(niu)，以達到(dao)使(shi)用(yong)(yong)者(zhe)的(de)目的(de)。由于(yu)當時(shi)技術(shu)并不(bu)(bu)先(xian)進，導致手(shou)(shou)機及平板很多(duo)功(gong)(gong)能未被開發出來(lai)，而使(shi)得(de)電(dian)(dian)容筆(bi)的(de)用(yong)(yong)途受到(dao)較(jiao)大的(de)局限，不(bu)(bu)過現如(ru)(ru)今(jin)不(bu)(bu)管是硬件(jian)還是軟(ruan)件(jian)技術(shu)都得(de)到(dao)跨越性的(de)提升，電(dian)(dian)容筆(bi)的(de)用(yong)(yong)途更加(jia)廣(guang)泛(fan)。現如(ru)(ru)今(jin)，隨著更多(duo)App的(de)較(jiao)完善的(de)功(gong)(gong)能開發，讓電(dian)(dian)容筆(bi)的(de)功(gong)(gong)能也產(chan)生質的(de)改(gai)變，不(bu)(bu)再只是用(yong)(yong)于(yu)觸(chu)控操作(zuo)(zuo)這么簡單。現如(ru)(ru)今(jin)電(dian)(dian)容筆(bi)已經可以直接在移動設備，如(ru)(ru)手(shou)(shou)機、筆(bi)記本、平板等(deng)(deng)，利用(yong)(yong)APP的(de)功(gong)(gong)能開展工作(zuo)(zuo)，比如(ru)(ru)進行(xing)繪(hui)畫、制圖、更正或(huo)者(zhe)標注文(wen)檔等(deng)(deng)，也可對(dui)相關會議或(huo)談話現場進行(xing)快速記錄等(deng)(deng)。
五、電容筆的工作原理
要知道電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)的(de)(de)(de)工作原(yuan)理，首先要了解(jie)與電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)配套(tao)使用的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)的(de)(de)(de)原(yuan)理：電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)是利用人(ren)(ren)體(ti)(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)感應(ying)工作的(de)(de)(de)，電(dian)(dian)(dian)(dian)(dian)容(rong)觸摸(mo)屏(ping)利用人(ren)(ren)體(ti)(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)感應(ying)進(jin)行(xing)工作，當手指觸摸(mo)在金屬(shu)層上時(shi)，由于人(ren)(ren)體(ti)(ti)電(dian)(dian)(dian)(dian)(dian)場、用戶和觸控屏(ping)表面(mian)形成以一個(ge)耦合(he)電(dian)(dian)(dian)(dian)(dian)容(rong)，對于高(gao)頻電(dian)(dian)(dian)(dian)(dian)流(liu)來說，電(dian)(dian)(dian)(dian)(dian)容(rong)是直接(jie)導(dao)體(ti)(ti)，于是手指從(cong)接(jie)觸點吸走一個(ge)很小的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)。這(zhe)個(ge)電(dian)(dian)(dian)(dian)(dian)流(liu)分別從(cong)觸控屏(ping)四角(jiao)(jiao)上的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極(ji)中流(liu)出，并且流(liu)經這(zhe)四個(ge)電(dian)(dian)(dian)(dian)(dian)極(ji)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)與手指到四角(jiao)(jiao)的(de)(de)(de)距(ju)離成正比，控制器通(tong)過(guo)對這(zhe)四個(ge)電(dian)(dian)(dian)(dian)(dian)流(liu)比例的(de)(de)(de)精(jing)確(que)計(ji)算，得出觸摸(mo)點的(de)(de)(de)位置信息(xi)。電(dian)(dian)(dian)(dian)(dian)容(rong)筆(bi)就(jiu)是通(tong)過(guo)導(dao)體(ti)(ti)模擬人(ren)(ren)體(ti)(ti)手指，筆(bi)尖觸摸(mo)電(dian)(dian)(dian)(dian)(dian)容(rong)屏(ping)時(shi)同(tong)樣產生電(dian)(dian)(dian)(dian)(dian)流(liu)，控制器對電(dian)(dian)(dian)(dian)(dian)流(liu)計(ji)算得出觸摸(mo)信息(xi)，并完(wan)成操作。
