一、電容筆和觸控筆的區別

電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)是(shi)利(li)用(yong)(yong)(yong)(yong)(yong)導(dao)體(ti)材料(liao)制作的(de)(de)(de)(de)具(ju)有(you)的(de)(de)(de)(de)導(dao)電(dian)特性，用(yong)(yong)(yong)(yong)(yong)來(lai)在(zai)(zai)(zai)觸(chu)(chu)控(kong)電(dian)容(rong)(rong)(rong)式(shi)屏(ping)(ping)幕(mu)(mu)完成人機(ji)對話操(cao)作用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)，是(shi)利(li)用(yong)(yong)(yong)(yong)(yong)導(dao)體(ti)材料(liao)模仿人體(ti)（通常是(shi)手指(zhi)）完成人機(ji)對話一種輔助裝置。觸(chu)(chu)控(kong)筆(bi)(bi)(bi)(bi)(bi)是(shi)一種小筆(bi)(bi)(bi)(bi)(bi)形的(de)(de)(de)(de)工具(ju)，用(yong)(yong)(yong)(yong)(yong)來(lai)輸(shu)入(ru)指(zhi)令到電(dian)腦屏(ping)(ping)幕(mu)(mu)、移動設備(bei)(bei)、繪(hui)(hui)圖(tu)板(ban)等具(ju)有(you)觸(chu)(chu)摸(mo)屏(ping)(ping)的(de)(de)(de)(de)設備(bei)(bei)，用(yong)(yong)(yong)(yong)(yong)戶可以通過觸(chu)(chu)控(kong)筆(bi)(bi)(bi)(bi)(bi)點擊觸(chu)(chu)控(kong)屏(ping)(ping)幕(mu)(mu)來(lai)選取文件或繪(hui)(hui)畫。電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)和觸(chu)(chu)控(kong)筆(bi)(bi)(bi)(bi)(bi)兩者的(de)(de)(de)(de)區別在(zai)(zai)(zai)導(dao)體(ti)材料(liao)、作用(yong)(yong)(yong)(yong)(yong)機(ji)制和適用(yong)(yong)(yong)(yong)(yong)對象的(de)(de)(de)(de)不(bu)同：電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)筆(bi)(bi)(bi)(bi)(bi)頭帶有(you)靜(jing)電(dian)，電(dian)容(rong)(rong)(rong)屏(ping)(ping)幕(mu)(mu)本身有(you)感應靜(jing)電(dian)的(de)(de)(de)(de)技術(shu)特點，所以電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)適用(yong)(yong)(yong)(yong)(yong)于電(dian)容(rong)(rong)(rong)屏(ping)(ping)；而普通的(de)(de)(de)(de)觸(chu)(chu)控(kong)筆(bi)(bi)(bi)(bi)(bi)是(shi)靠按壓屏(ping)(ping)幕(mu)(mu)，適用(yong)(yong)(yong)(yong)(yong)于電(dian)阻屏(ping)(ping)。電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)和觸(chu)(chu)控(kong)筆(bi)(bi)(bi)(bi)(bi)哪個好，寫字(zi)繪(hui)(hui)畫用(yong)(yong)(yong)(yong)(yong)哪種筆(bi)(bi)(bi)(bi)(bi)主要要根據選擇的(de)(de)(de)(de)產品來(lai)看，不(bu)同的(de)(de)(de)(de)屏(ping)(ping)幕(mu)(mu)適應不(bu)同的(de)(de)(de)(de)筆(bi)(bi)(bi)(bi)(bi)：觸(chu)(chu)控(kong)筆(bi)(bi)(bi)(bi)(bi)主要適用(yong)(yong)(yong)(yong)(yong)于電(dian)阻屏(ping)(ping)，電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)適用(yong)(yong)(yong)(yong)(yong)于電(dian)容(rong)(rong)(rong)屏(ping)(ping)，現在(zai)(zai)(zai)的(de)(de)(de)(de)平板(ban)、手機(ji)等設備(bei)(bei)基本上(shang)都是(shi)用(yong)(yong)(yong)(yong)(yong)的(de)(de)(de)(de)電(dian)容(rong)(rong)(rong)屏(ping)(ping)，因此一般現在(zai)(zai)(zai)用(yong)(yong)(yong)(yong)(yong)電(dian)容(rong)(rong)(rong)筆(bi)(bi)(bi)(bi)(bi)比(bi)較(jiao)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)要注意考慮電容(rong)筆(bi)的防誤觸功能(neng)、延遲、筆(bi)尖(jian)材質、續(xu)航能(neng)力、有無壓感功能(neng)等方面(mian)。

三、電容筆怎么連接平板

電(dian)容(rong)(rong)筆(bi)(bi)分為(wei)被動(dong)式電(dian)容(rong)(rong)筆(bi)(bi)和主動(dong)式電(dian)容(rong)(rong)筆(bi)(bi)，被動(dong)式電(dian)容(rong)(rong)筆(bi)(bi)可以直接(jie)用，主動(dong)式電(dian)容(rong)(rong)筆(bi)(bi)內(nei)置芯片，需要連(lian)接(jie)才(cai)能使(shi)(shi)用，連(lian)接(jie)方法很簡單：1、將手寫(xie)筆(bi)(bi)放在平(ping)板(ban)附近，拉下狀(zhuang)態欄，將藍(lan)(lan)(lan)(lan)牙打開，再長(chang)按(an)“藍(lan)(lan)(lan)(lan)牙”，進入藍(lan)(lan)(lan)(lan)牙界面(mian)(mian)。2、這時(shi)，藍(lan)(lan)(lan)(lan)牙會自動(dong)彈出連(lian)接(jie)界面(mian)(mian)，點擊“連(lian)接(jie)”即可，如果沒有(you)彈出，也可以在藍(lan)(lan)(lan)(lan)牙搜索界面(mian)(mian)里找到手寫(xie)筆(bi)(bi)的ID，然后連(lian)接(jie)。3、連(lian)接(jie)好后，手寫(xie)筆(bi)(bi)就(jiu)可以使(shi)(shi)用了。

四、電容筆是干什么用的

電(dian)容(rong)筆(bi)(bi)(bi)在最初出(chu)現(xian)(xian)(xian)的(de)時候，較(jiao)為普(pu)遍地使用在部(bu)分帶有(you)觸屏(ping)功(gong)能的(de)手機(ji)上，可以用電(dian)容(rong)筆(bi)(bi)(bi)進行操作(zuo)，用于(yu)操作(zuo)對(dui)應的(de)屏(ping)幕上方(fang)功(gong)能按鈕，以達到(dao)使用者(zhe)的(de)目(mu)的(de)。由于(yu)當時技術并不(bu)(bu)先進，導致(zhi)手機(ji)及(ji)平(ping)板(ban)很(hen)多功(gong)能未(wei)被開(kai)發出(chu)來(lai)，而使得電(dian)容(rong)筆(bi)(bi)(bi)的(de)用途受(shou)到(dao)較(jiao)大的(de)局限，不(bu)(bu)過現(xian)(xian)(xian)如(ru)(ru)今(jin)不(bu)(bu)管是硬(ying)件還(huan)是軟件技術都得到(dao)跨越(yue)性的(de)提升，電(dian)容(rong)筆(bi)(bi)(bi)的(de)用途更(geng)加廣(guang)泛。現(xian)(xian)(xian)如(ru)(ru)今(jin)，隨(sui)著更(geng)多App的(de)較(jiao)完善的(de)功(gong)能開(kai)發，讓電(dian)容(rong)筆(bi)(bi)(bi)的(de)功(gong)能也產生(sheng)質的(de)改(gai)變(bian)，不(bu)(bu)再只是用于(yu)觸控操作(zuo)這么(me)簡(jian)單。現(xian)(xian)(xian)如(ru)(ru)今(jin)電(dian)容(rong)筆(bi)(bi)(bi)已經可以直(zhi)接在移動(dong)設備，如(ru)(ru)手機(ji)、筆(bi)(bi)(bi)記(ji)本、平(ping)板(ban)等(deng)，利用APP的(de)功(gong)能開(kai)展工作(zuo)，比如(ru)(ru)進行繪(hui)畫、制圖、更(geng)正(zheng)或者(zhe)標注文檔等(deng)，也可對(dui)相關會議或談話現(xian)(xian)(xian)場(chang)進行快速記(ji)錄(lu)等(deng)。

五、電容筆的工作原理

要知(zhi)道電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆的(de)(de)(de)工作(zuo)原(yuan)理，首先要了解與(yu)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆配(pei)套使(shi)用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)的(de)(de)(de)原(yuan)理：電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)是利(li)(li)用(yong)人(ren)體(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)感應(ying)工作(zuo)的(de)(de)(de)，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)觸(chu)(chu)(chu)摸屏(ping)利(li)(li)用(yong)人(ren)體(ti)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)感應(ying)進行工作(zuo)，當手指觸(chu)(chu)(chu)摸在金屬層上時，由于(yu)人(ren)體(ti)電(dian)(dian)(dian)(dian)(dian)場、用(yong)戶和觸(chu)(chu)(chu)控(kong)屏(ping)表面形(xing)成以(yi)一個(ge)耦合電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)，對(dui)(dui)于(yu)高(gao)頻電(dian)(dian)(dian)(dian)(dian)流(liu)來說，電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)是直(zhi)接導(dao)體(ti)，于(yu)是手指從接觸(chu)(chu)(chu)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(bie)從觸(chu)(chu)(chu)控(kong)屏(ping)四(si)(si)角上的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)極中流(liu)出，并(bing)且(qie)流(liu)經這(zhe)四(si)(si)個(ge)電(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)與(yu)手指到四(si)(si)角的(de)(de)(de)距離成正比(bi)，控(kong)制器(qi)通(tong)過對(dui)(dui)這(zhe)四(si)(si)個(ge)電(dian)(dian)(dian)(dian)(dian)流(liu)比(bi)例的(de)(de)(de)精確計(ji)算，得出觸(chu)(chu)(chu)摸點的(de)(de)(de)位置信(xin)息。電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)筆就(jiu)是通(tong)過導(dao)體(ti)模擬人(ren)體(ti)手指，筆尖觸(chu)(chu)(chu)摸電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)屏(ping)時同樣(yang)產生電(dian)(dian)(dian)(dian)(dian)流(liu)，控(kong)制器(qi)對(dui)(dui)電(dian)(dian)(dian)(dian)(dian)流(liu)計(ji)算得出觸(chu)(chu)(chu)摸信(xin)息，并(bing)完(wan)成操作(zuo)。
