一、電容筆和觸控筆的區別

電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)(bi)是(shi)(shi)利(li)用導(dao)(dao)體材(cai)料(liao)(liao)制作(zuo)的(de)(de)(de)(de)(de)具有的(de)(de)(de)(de)(de)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)特性，用來(lai)(lai)在(zai)(zai)觸(chu)(chu)(chu)控(kong)(kong)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)式屏(ping)(ping)(ping)(ping)幕(mu)完成人(ren)(ren)機對(dui)話操作(zuo)用的(de)(de)(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)(bi)，是(shi)(shi)利(li)用導(dao)(dao)體材(cai)料(liao)(liao)模仿(fang)人(ren)(ren)體（通常是(shi)(shi)手指(zhi)）完成人(ren)(ren)機對(dui)話一(yi)種輔助(zhu)裝置。觸(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)(bi)是(shi)(shi)一(yi)種小筆(bi)(bi)(bi)(bi)(bi)(bi)形的(de)(de)(de)(de)(de)工具，用來(lai)(lai)輸(shu)入指(zhi)令到電(dian)(dian)(dian)(dian)(dian)腦屏(ping)(ping)(ping)(ping)幕(mu)、移動(dong)設(she)備、繪(hui)圖(tu)板等(deng)具有觸(chu)(chu)(chu)摸屏(ping)(ping)(ping)(ping)的(de)(de)(de)(de)(de)設(she)備，用戶可以通過觸(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)(bi)點擊觸(chu)(chu)(chu)控(kong)(kong)屏(ping)(ping)(ping)(ping)幕(mu)來(lai)(lai)選(xuan)(xuan)取文件或繪(hui)畫。電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)(bi)和觸(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)(bi)兩者的(de)(de)(de)(de)(de)區別(bie)在(zai)(zai)導(dao)(dao)體材(cai)料(liao)(liao)、作(zuo)用機制和適(shi)(shi)用對(dui)象的(de)(de)(de)(de)(de)不同(tong)：電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)(bi)(bi)頭帶有靜電(dian)(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)幕(mu)本身有感應靜電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)技術特點，所以電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)(bi)適(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)；而(er)普通的(de)(de)(de)(de)(de)觸(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)(bi)是(shi)(shi)靠按(an)壓(ya)屏(ping)(ping)(ping)(ping)幕(mu)，適(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)屏(ping)(ping)(ping)(ping)。電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)(bi)和觸(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)(bi)哪個好(hao)，寫字繪(hui)畫用哪種筆(bi)(bi)(bi)(bi)(bi)(bi)主(zhu)要要根據選(xuan)(xuan)擇的(de)(de)(de)(de)(de)產品來(lai)(lai)看(kan)，不同(tong)的(de)(de)(de)(de)(de)屏(ping)(ping)(ping)(ping)幕(mu)適(shi)(shi)應不同(tong)的(de)(de)(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)(bi)：觸(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)(bi)(bi)(bi)主(zhu)要適(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)阻(zu)(zu)屏(ping)(ping)(ping)(ping)，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)(bi)適(shi)(shi)用于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)，現在(zai)(zai)的(de)(de)(de)(de)(de)平(ping)板、手機等(deng)設(she)備基本上都是(shi)(shi)用的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)，因此(ci)一(yi)般(ban)現在(zai)(zai)用電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)筆(bi)(bi)(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，還要注意考慮電容(rong)筆(bi)的防誤觸功能、延遲(chi)、筆(bi)尖材質、續航(hang)能力、有(you)無壓感功能等方面。

三、電容筆怎么連接平板

電(dian)(dian)容筆(bi)分為被動(dong)式電(dian)(dian)容筆(bi)和(he)主(zhu)動(dong)式電(dian)(dian)容筆(bi)，被動(dong)式電(dian)(dian)容筆(bi)可以直接用(yong)，主(zhu)動(dong)式電(dian)(dian)容筆(bi)內(nei)置芯片，需要連(lian)接才能使用(yong)，連(lian)接方(fang)法(fa)很簡單：1、將手寫筆(bi)放在平板附(fu)近，拉下狀態欄，將藍牙(ya)(ya)(ya)(ya)打開，再長(chang)按“藍牙(ya)(ya)(ya)(ya)”，進(jin)入藍牙(ya)(ya)(ya)(ya)界面。2、這時，藍牙(ya)(ya)(ya)(ya)會(hui)自動(dong)彈出(chu)連(lian)接界面，點擊“連(lian)接”即(ji)可，如果沒有彈出(chu)，也(ye)可以在藍牙(ya)(ya)(ya)(ya)搜索界面里找到手寫筆(bi)的ID，然后(hou)連(lian)接。3、連(lian)接好(hao)后(hou)，手寫筆(bi)就可以使用(yong)了。

四、電容筆是干什么用的

電(dian)(dian)(dian)(dian)容(rong)(rong)筆在(zai)最初(chu)出現(xian)的(de)(de)(de)(de)時(shi)(shi)候，較為普遍地使用(yong)(yong)在(zai)部分帶有觸(chu)屏(ping)(ping)功(gong)(gong)能(neng)的(de)(de)(de)(de)手機上(shang)，可以(yi)用(yong)(yong)電(dian)(dian)(dian)(dian)容(rong)(rong)筆進(jin)行操作，用(yong)(yong)于操作對應(ying)的(de)(de)(de)(de)屏(ping)(ping)幕上(shang)方(fang)功(gong)(gong)能(neng)按鈕，以(yi)達到(dao)(dao)使用(yong)(yong)者(zhe)的(de)(de)(de)(de)目的(de)(de)(de)(de)。由于當時(shi)(shi)技術(shu)并不先進(jin)，導致手機及平(ping)板很多功(gong)(gong)能(neng)未被開發出來，而使得電(dian)(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)用(yong)(yong)途(tu)受到(dao)(dao)較大的(de)(de)(de)(de)局限，不過現(xian)如今不管是(shi)(shi)硬件還是(shi)(shi)軟(ruan)件技術(shu)都(dou)得到(dao)(dao)跨越(yue)性(xing)的(de)(de)(de)(de)提(ti)升，電(dian)(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)用(yong)(yong)途(tu)更加廣泛。現(xian)如今，隨著更多App的(de)(de)(de)(de)較完善(shan)的(de)(de)(de)(de)功(gong)(gong)能(neng)開發，讓電(dian)(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)(de)功(gong)(gong)能(neng)也產生質的(de)(de)(de)(de)改變，不再只是(shi)(shi)用(yong)(yong)于觸(chu)控操作這么簡單。現(xian)如今電(dian)(dian)(dian)(dian)容(rong)(rong)筆已經可以(yi)直接在(zai)移動設備(bei)，如手機、筆記本、平(ping)板等，利用(yong)(yong)APP的(de)(de)(de)(de)功(gong)(gong)能(neng)開展工作，比如進(jin)行繪(hui)畫、制圖、更正或者(zhe)標(biao)注文檔等，也可對相關會議或談話(hua)現(xian)場(chang)進(jin)行快(kuai)速記錄(lu)等。

五、電容筆的工作原理

要(yao)知道電(dian)(dian)(dian)(dian)容(rong)筆(bi)的(de)工(gong)作(zuo)(zuo)原理，首先(xian)要(yao)了解(jie)與(yu)電(dian)(dian)(dian)(dian)容(rong)筆(bi)配套(tao)使(shi)用的(de)電(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)的(de)原理：電(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)是利用人(ren)(ren)體的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)感應工(gong)作(zuo)(zuo)的(de)，電(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)利用人(ren)(ren)體的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)感應進行工(gong)作(zuo)(zuo)，當手(shou)指(zhi)觸(chu)(chu)摸(mo)(mo)在金屬層上(shang)時(shi)，由于人(ren)(ren)體電(dian)(dian)(dian)(dian)場、用戶和(he)觸(chu)(chu)控屏(ping)(ping)表(biao)面形成(cheng)以(yi)一(yi)個(ge)耦合電(dian)(dian)(dian)(dian)容(rong)，對(dui)于高頻電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)來說，電(dian)(dian)(dian)(dian)容(rong)是直接(jie)(jie)導(dao)體，于是手(shou)指(zhi)從接(jie)(jie)觸(chu)(chu)點(dian)吸走一(yi)個(ge)很小的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)。這個(ge)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)分別從觸(chu)(chu)控屏(ping)(ping)四(si)角上(shang)的(de)電(dian)(dian)(dian)(dian)極中流(liu)(liu)(liu)(liu)出(chu)，并(bing)且流(liu)(liu)(liu)(liu)經這四(si)個(ge)電(dian)(dian)(dian)(dian)極的(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)與(yu)手(shou)指(zhi)到四(si)角的(de)距離成(cheng)正比(bi)，控制器通過對(dui)這四(si)個(ge)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)比(bi)例的(de)精確計(ji)算，得(de)出(chu)觸(chu)(chu)摸(mo)(mo)點(dian)的(de)位(wei)置(zhi)信(xin)息。電(dian)(dian)(dian)(dian)容(rong)筆(bi)就是通過導(dao)體模擬人(ren)(ren)體手(shou)指(zhi)，筆(bi)尖(jian)觸(chu)(chu)摸(mo)(mo)電(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)時(shi)同樣產(chan)生(sheng)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，控制器對(dui)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)計(ji)算得(de)出(chu)觸(chu)(chu)摸(mo)(mo)信(xin)息，并(bing)完成(cheng)操作(zuo)(zuo)。
