一、電容筆和觸控筆的區別

電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)是利(li)用(yong)導(dao)體材(cai)(cai)料(liao)制作的(de)(de)(de)具(ju)有(you)的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)(dian)特性，用(yong)來在(zai)觸(chu)(chu)控(kong)(kong)(kong)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)式屏(ping)幕完(wan)成(cheng)人(ren)機(ji)(ji)對(dui)話操作用(yong)的(de)(de)(de)筆(bi)(bi)，是利(li)用(yong)導(dao)體材(cai)(cai)料(liao)模仿人(ren)體（通常(chang)是手指）完(wan)成(cheng)人(ren)機(ji)(ji)對(dui)話一種(zhong)輔助(zhu)裝(zhuang)置。觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)是一種(zhong)小(xiao)筆(bi)(bi)形的(de)(de)(de)工具(ju)，用(yong)來輸(shu)入指令到電(dian)(dian)(dian)(dian)(dian)腦屏(ping)幕、移動設備、繪(hui)(hui)圖板等(deng)具(ju)有(you)觸(chu)(chu)摸屏(ping)的(de)(de)(de)設備，用(yong)戶可以(yi)通過觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)點擊觸(chu)(chu)控(kong)(kong)(kong)屏(ping)幕來選取(qu)文件或繪(hui)(hui)畫(hua)。電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)和觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)兩者的(de)(de)(de)區別在(zai)導(dao)體材(cai)(cai)料(liao)、作用(yong)機(ji)(ji)制和適(shi)用(yong)對(dui)象的(de)(de)(de)不(bu)同：電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)筆(bi)(bi)頭帶有(you)靜(jing)電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)幕本身有(you)感應靜(jing)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)技術特點，所以(yi)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)適(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)；而普(pu)通的(de)(de)(de)觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)是靠按壓屏(ping)幕，適(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)阻屏(ping)。電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)和觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)哪(na)個(ge)好，寫字繪(hui)(hui)畫(hua)用(yong)哪(na)種(zhong)筆(bi)(bi)主(zhu)要(yao)(yao)要(yao)(yao)根(gen)據(ju)選擇的(de)(de)(de)產(chan)品來看，不(bu)同的(de)(de)(de)屏(ping)幕適(shi)應不(bu)同的(de)(de)(de)筆(bi)(bi)：觸(chu)(chu)控(kong)(kong)(kong)筆(bi)(bi)主(zhu)要(yao)(yao)適(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)阻屏(ping)，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)適(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)，現(xian)在(zai)的(de)(de)(de)平(ping)板、手機(ji)(ji)等(deng)設備基本上(shang)都是用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)，因此一般現(xian)在(zai)用(yong)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆(bi)(bi)比(bi)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(huan)要注意考慮(lv)電容筆(bi)的防誤觸(chu)功(gong)能、延遲(chi)、筆(bi)尖材質、續航(hang)能力(li)、有無壓感(gan)功(gong)能等方(fang)面。

三、電容筆怎么連接平板

電容(rong)(rong)筆分為被動(dong)式電容(rong)(rong)筆和主(zhu)動(dong)式電容(rong)(rong)筆，被動(dong)式電容(rong)(rong)筆可(ke)以直(zhi)接(jie)(jie)用(yong)，主(zhu)動(dong)式電容(rong)(rong)筆內置芯(xin)片，需(xu)要(yao)連接(jie)(jie)才(cai)能使用(yong)，連接(jie)(jie)方法(fa)很簡單：1、將(jiang)(jiang)手(shou)寫(xie)(xie)筆放在(zai)平板附近，拉下狀態欄，將(jiang)(jiang)藍牙(ya)打開，再長(chang)按(an)“藍牙(ya)”，進入藍牙(ya)界面(mian)。2、這時，藍牙(ya)會(hui)自動(dong)彈出(chu)連接(jie)(jie)界面(mian)，點(dian)擊“連接(jie)(jie)”即(ji)可(ke)，如果(guo)沒有彈出(chu)，也(ye)可(ke)以在(zai)藍牙(ya)搜索界面(mian)里找到手(shou)寫(xie)(xie)筆的ID，然后(hou)連接(jie)(jie)。3、連接(jie)(jie)好后(hou)，手(shou)寫(xie)(xie)筆就可(ke)以使用(yong)了(le)。

四、電容筆是干什么用的

電(dian)容筆(bi)在(zai)最初(chu)出現(xian)的(de)時候，較(jiao)為普遍地使用(yong)(yong)在(zai)部分帶有觸(chu)屏功能(neng)的(de)手(shou)機(ji)上(shang)，可(ke)(ke)以(yi)用(yong)(yong)電(dian)容筆(bi)進(jin)行操作，用(yong)(yong)于操作對(dui)應的(de)屏幕上(shang)方功能(neng)按鈕，以(yi)達到使用(yong)(yong)者(zhe)的(de)目的(de)。由于當時技術并不(bu)(bu)(bu)先進(jin)，導致手(shou)機(ji)及平板很(hen)多功能(neng)未被(bei)開(kai)發(fa)(fa)出來，而使得(de)(de)電(dian)容筆(bi)的(de)用(yong)(yong)途受到較(jiao)大的(de)局(ju)限，不(bu)(bu)(bu)過(guo)現(xian)如今不(bu)(bu)(bu)管是硬(ying)件還是軟(ruan)件技術都得(de)(de)到跨(kua)越性的(de)提升，電(dian)容筆(bi)的(de)用(yong)(yong)途更加(jia)廣泛。現(xian)如今，隨著更多App的(de)較(jiao)完善的(de)功能(neng)開(kai)發(fa)(fa)，讓電(dian)容筆(bi)的(de)功能(neng)也產生(sheng)質的(de)改(gai)變，不(bu)(bu)(bu)再只是用(yong)(yong)于觸(chu)控操作這(zhe)么(me)簡(jian)單。現(xian)如今電(dian)容筆(bi)已(yi)經(jing)可(ke)(ke)以(yi)直(zhi)接在(zai)移動設備，如手(shou)機(ji)、筆(bi)記(ji)(ji)本、平板等(deng)，利用(yong)(yong)APP的(de)功能(neng)開(kai)展工作，比如進(jin)行繪(hui)畫、制圖(tu)、更正或者(zhe)標注文檔等(deng)，也可(ke)(ke)對(dui)相關會議或談(tan)話現(xian)場進(jin)行快速記(ji)(ji)錄等(deng)。

五、電容筆的工作原理

要(yao)知道電(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)工作原理，首先要(yao)了解與電(dian)(dian)(dian)容(rong)(rong)筆配套使用的(de)(de)(de)(de)電(dian)(dian)(dian)容(rong)(rong)屏(ping)的(de)(de)(de)(de)原理：電(dian)(dian)(dian)容(rong)(rong)屏(ping)是利用人體(ti)(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)感應工作的(de)(de)(de)(de)，電(dian)(dian)(dian)容(rong)(rong)觸(chu)摸(mo)屏(ping)利用人體(ti)(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)感應進(jin)行工作，當手(shou)指觸(chu)摸(mo)在(zai)金屬(shu)層上時，由(you)于人體(ti)(ti)電(dian)(dian)(dian)場、用戶和(he)觸(chu)控(kong)屏(ping)表(biao)面形成(cheng)以(yi)一個(ge)耦合電(dian)(dian)(dian)容(rong)(rong)，對(dui)于高(gao)頻電(dian)(dian)(dian)流(liu)來說，電(dian)(dian)(dian)容(rong)(rong)是直(zhi)接(jie)導(dao)體(ti)(ti)，于是手(shou)指從接(jie)觸(chu)點(dian)吸走一個(ge)很小的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)。這(zhe)個(ge)電(dian)(dian)(dian)流(liu)分別從觸(chu)控(kong)屏(ping)四(si)角上的(de)(de)(de)(de)電(dian)(dian)(dian)極(ji)中流(liu)出，并(bing)且流(liu)經這(zhe)四(si)個(ge)電(dian)(dian)(dian)極(ji)的(de)(de)(de)(de)電(dian)(dian)(dian)流(liu)與手(shou)指到(dao)四(si)角的(de)(de)(de)(de)距離成(cheng)正比，控(kong)制器通過對(dui)這(zhe)四(si)個(ge)電(dian)(dian)(dian)流(liu)比例的(de)(de)(de)(de)精確計算，得出觸(chu)摸(mo)點(dian)的(de)(de)(de)(de)位(wei)置(zhi)信息(xi)。電(dian)(dian)(dian)容(rong)(rong)筆就是通過導(dao)體(ti)(ti)模(mo)擬人體(ti)(ti)手(shou)指，筆尖觸(chu)摸(mo)電(dian)(dian)(dian)容(rong)(rong)屏(ping)時同樣產生電(dian)(dian)(dian)流(liu)，控(kong)制器對(dui)電(dian)(dian)(dian)流(liu)計算得出觸(chu)摸(mo)信息(xi)，并(bing)完成(cheng)操(cao)作。
