一、電容筆和觸控筆的區別
電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)是(shi)(shi)利用(yong)導(dao)體(ti)材(cai)料(liao)制作(zuo)(zuo)的(de)(de)(de)具(ju)有的(de)(de)(de)導(dao)電(dian)(dian)(dian)(dian)特性，用(yong)來(lai)在(zai)觸(chu)(chu)(chu)(chu)控(kong)(kong)電(dian)(dian)(dian)(dian)容式屏(ping)(ping)幕完成人(ren)機對(dui)話操(cao)作(zuo)(zuo)用(yong)的(de)(de)(de)筆(bi)(bi)(bi)，是(shi)(shi)利用(yong)導(dao)體(ti)材(cai)料(liao)模(mo)仿人(ren)體(ti)（通常是(shi)(shi)手指）完成人(ren)機對(dui)話一(yi)種(zhong)輔助裝置。觸(chu)(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)是(shi)(shi)一(yi)種(zhong)小筆(bi)(bi)(bi)形的(de)(de)(de)工具(ju)，用(yong)來(lai)輸入(ru)指令到電(dian)(dian)(dian)(dian)腦屏(ping)(ping)幕、移動設備(bei)、繪圖板等具(ju)有觸(chu)(chu)(chu)(chu)摸屏(ping)(ping)的(de)(de)(de)設備(bei)，用(yong)戶可(ke)以通過觸(chu)(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)點擊觸(chu)(chu)(chu)(chu)控(kong)(kong)屏(ping)(ping)幕來(lai)選取文件或繪畫(hua)。電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)和(he)觸(chu)(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)兩者的(de)(de)(de)區別在(zai)導(dao)體(ti)材(cai)料(liao)、作(zuo)(zuo)用(yong)機制和(he)適(shi)(shi)用(yong)對(dui)象(xiang)的(de)(de)(de)不(bu)同：電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)筆(bi)(bi)(bi)頭帶有靜電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)容屏(ping)(ping)幕本身有感(gan)應(ying)靜電(dian)(dian)(dian)(dian)的(de)(de)(de)技術特點，所(suo)以電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)適(shi)(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)容屏(ping)(ping)；而普通的(de)(de)(de)觸(chu)(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)是(shi)(shi)靠按(an)壓(ya)屏(ping)(ping)幕，適(shi)(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)阻屏(ping)(ping)。電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)和(he)觸(chu)(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)哪個好(hao)，寫字(zi)繪畫(hua)用(yong)哪種(zhong)筆(bi)(bi)(bi)主(zhu)要要根據選擇的(de)(de)(de)產品來(lai)看，不(bu)同的(de)(de)(de)屏(ping)(ping)幕適(shi)(shi)應(ying)不(bu)同的(de)(de)(de)筆(bi)(bi)(bi)：觸(chu)(chu)(chu)(chu)控(kong)(kong)筆(bi)(bi)(bi)主(zhu)要適(shi)(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)阻屏(ping)(ping)，電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)適(shi)(shi)用(yong)于(yu)(yu)電(dian)(dian)(dian)(dian)容屏(ping)(ping)，現在(zai)的(de)(de)(de)平板、手機等設備(bei)基(ji)本上都是(shi)(shi)用(yong)的(de)(de)(de)電(dian)(dian)(dian)(dian)容屏(ping)(ping)，因此一(yi)般現在(zai)用(yong)電(dian)(dian)(dian)(dian)容筆(bi)(bi)(bi)比較多(duo)。
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誤(wu)觸功(gong)能(neng)、延遲、筆尖材質、續航(hang)能(neng)力、有無壓感(gan)功(gong)能(neng)等方面。
三、電容筆怎么連接平板
電容筆(bi)(bi)分(fen)為被動式(shi)電容筆(bi)(bi)和(he)主動式(shi)電容筆(bi)(bi)，被動式(shi)電容筆(bi)(bi)可(ke)以(yi)直接(jie)用(yong)，主動式(shi)電容筆(bi)(bi)內置芯片，需要連接(jie)才能使用(yong)，連接(jie)方法很簡單：1、將(jiang)手(shou)寫筆(bi)(bi)放在平板附近，拉下狀態(tai)欄，將(jiang)藍(lan)牙(ya)打(da)開，再長(chang)按(an)“藍(lan)牙(ya)”，進入藍(lan)牙(ya)界面(mian)。2、這時，藍(lan)牙(ya)會自動彈出(chu)連接(jie)界面(mian)，點擊“連接(jie)”即可(ke)，如(ru)果沒有彈出(chu)，也可(ke)以(yi)在藍(lan)牙(ya)搜索界面(mian)里(li)找(zhao)到(dao)手(shou)寫筆(bi)(bi)的ID，然后連接(jie)。3、連接(jie)好(hao)后，手(shou)寫筆(bi)(bi)就可(ke)以(yi)使用(yong)了(le)。
四、電容筆是干什么用的
電容(rong)筆(bi)(bi)在最初(chu)出現(xian)的(de)(de)(de)(de)(de)時候，較(jiao)為普遍地使用(yong)在部分帶有觸屏功能(neng)的(de)(de)(de)(de)(de)手(shou)機(ji)上，可(ke)以(yi)用(yong)電容(rong)筆(bi)(bi)進(jin)行操(cao)作(zuo)，用(yong)于操(cao)作(zuo)對(dui)應的(de)(de)(de)(de)(de)屏幕(mu)上方功能(neng)按鈕(niu)，以(yi)達到使用(yong)者的(de)(de)(de)(de)(de)目(mu)的(de)(de)(de)(de)(de)。由于當時技術(shu)并不(bu)(bu)先進(jin)，導致手(shou)機(ji)及(ji)平(ping)板很多功能(neng)未被(bei)開(kai)(kai)發出來，而(er)使得電容(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)用(yong)途受(shou)到較(jiao)大的(de)(de)(de)(de)(de)局限，不(bu)(bu)過(guo)現(xian)如(ru)今(jin)不(bu)(bu)管是(shi)硬件還是(shi)軟件技術(shu)都得到跨越性(xing)的(de)(de)(de)(de)(de)提升，電容(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)用(yong)途更(geng)加廣泛(fan)。現(xian)如(ru)今(jin)，隨著更(geng)多App的(de)(de)(de)(de)(de)較(jiao)完善的(de)(de)(de)(de)(de)功能(neng)開(kai)(kai)發，讓電容(rong)筆(bi)(bi)的(de)(de)(de)(de)(de)功能(neng)也(ye)產生質的(de)(de)(de)(de)(de)改變，不(bu)(bu)再只(zhi)是(shi)用(yong)于觸控操(cao)作(zuo)這么簡(jian)單。現(xian)如(ru)今(jin)電容(rong)筆(bi)(bi)已(yi)經(jing)可(ke)以(yi)直(zhi)接在移動(dong)設(she)備，如(ru)手(shou)機(ji)、筆(bi)(bi)記本、平(ping)板等，利用(yong)APP的(de)(de)(de)(de)(de)功能(neng)開(kai)(kai)展(zhan)工作(zuo)，比如(ru)進(jin)行繪畫、制圖、更(geng)正或者標(biao)注文檔等，也(ye)可(ke)對(dui)相關(guan)會(hui)議(yi)或談話現(xian)場(chang)進(jin)行快速記錄等。
五、電容筆的工作原理
要知道(dao)電(dian)(dian)(dian)(dian)容(rong)筆(bi)的(de)(de)(de)(de)工(gong)作(zuo)原(yuan)理，首先要了解(jie)與(yu)電(dian)(dian)(dian)(dian)容(rong)筆(bi)配套使用的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)的(de)(de)(de)(de)原(yuan)理：電(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)是(shi)(shi)利用人(ren)(ren)體(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)感(gan)應工(gong)作(zuo)的(de)(de)(de)(de)，電(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)(chu)(chu)摸(mo)屏(ping)(ping)利用人(ren)(ren)體(ti)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)感(gan)應進行工(gong)作(zuo)，當手(shou)(shou)指(zhi)觸(chu)(chu)(chu)(chu)摸(mo)在金屬層上(shang)時(shi)，由于人(ren)(ren)體(ti)電(dian)(dian)(dian)(dian)場、用戶和(he)觸(chu)(chu)(chu)(chu)控屏(ping)(ping)表面形成以一個耦合電(dian)(dian)(dian)(dian)容(rong)，對(dui)于高(gao)頻電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)來說，電(dian)(dian)(dian)(dian)容(rong)是(shi)(shi)直接導(dao)體(ti)，于是(shi)(shi)手(shou)(shou)指(zhi)從接觸(chu)(chu)(chu)(chu)點吸走(zou)一個很小的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)。這個電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)分別從觸(chu)(chu)(chu)(chu)控屏(ping)(ping)四(si)(si)(si)角(jiao)上(shang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)極中流(liu)(liu)(liu)出，并(bing)且流(liu)(liu)(liu)經這四(si)(si)(si)個電(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)與(yu)手(shou)(shou)指(zhi)到(dao)四(si)(si)(si)角(jiao)的(de)(de)(de)(de)距離成正比，控制(zhi)器通過(guo)對(dui)這四(si)(si)(si)個電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)比例的(de)(de)(de)(de)精確計算(suan)，得出觸(chu)(chu)(chu)(chu)摸(mo)點的(de)(de)(de)(de)位(wei)置信(xin)息。電(dian)(dian)(dian)(dian)容(rong)筆(bi)就是(shi)(shi)通過(guo)導(dao)體(ti)模擬人(ren)(ren)體(ti)手(shou)(shou)指(zhi)，筆(bi)尖觸(chu)(chu)(chu)(chu)摸(mo)電(dian)(dian)(dian)(dian)容(rong)屏(ping)(ping)時(shi)同樣產(chan)生電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)，控制(zhi)器對(dui)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)計算(suan)得出觸(chu)(chu)(chu)(chu)摸(mo)信(xin)息，并(bing)完成操作(zuo)。
