電(dian)容(rong)觸(chu)摸(mo)屏(ping)的(de)(de)漂移問(wen)(wen)題(ti)(ti)。在觸(chu)摸(mo)屏(ping)產品中，電(dian)容(rong)觸(chu)摸(mo)屏(ping)是我們常用的(de)(de)觸(chu)摸(mo)屏(ping)方式，那(nei)么，對于電(dian)容(rong)觸(chu)摸(mo)屏(ping)來說，其產品本(ben)身應用比較(jiao)廣泛，但是也存在著不少問(wen)(wen)題(ti)(ti)。而且(qie)由(you)于現(xian)在科(ke)技的(de)(de)發展程度還(huan)無法(fa)完(wan)全解決觸(chu)摸(mo)屏(ping)產品在相關原(yuan)理上出(chu)現(xian)的(de)(de)問(wen)(wen)題(ti)(ti)，所以對于這些(xie)問(wen)(wen)題(ti)(ti)，目(mu)前還(huan)是普遍存在的(de)(de)。
在(zai)這(zhe)(zhe)里(li)武漢公司要跟大(da)家討論(lun)的(de)是(shi)關(guan)于(yu)電(dian)(dian)(dian)容觸摸(mo)(mo)屏(ping)的(de)"漂移"問(wen)題(ti)，這(zhe)(zhe)個問(wen)題(ti)比(bi)較(jiao)常見(jian)，也(ye)是(shi)我們(men)在(zai)解決產品問(wen)題(ti)時主要考慮的(de)方(fang)(fang)面。 電(dian)(dian)(dian)容觸摸(mo)(mo)屏(ping)的(de)漂移問(wen)題(ti)介紹！ 武漢觸摸(mo)(mo)屏(ping)公司提示，電(dian)(dian)(dian)容觸摸(mo)(mo)屏(ping)本(ben)身實(shi)際(ji)是(shi)一套精(jing)密的(de)漏(lou)電(dian)(dian)(dian)傳感器，帶手套的(de)手不(bu)能觸摸(mo)(mo)，由于(yu)使用電(dian)(dian)(dian)容方(fang)(fang)式，導(dao)致有(you)漂移現象。電(dian)(dian)(dian)容觸摸(mo)(mo)屏(ping)和電(dian)(dian)(dian)阻觸摸(mo)(mo)屏(ping)都(dou)是(shi)電(dian)(dian)(dian)原理(li)工作方(fang)(fang)式，電(dian)(dian)(dian)工作方(fang)(fang)式對于(yu)多(duo)點(dian)觸摸(mo)(mo)，不(bu)管是(shi)多(duo)少點(dian)，也(ye)不(bu)管是(shi)連續的(de)還是(shi)不(bu)連續的(de)都(dou)是(shi)取多(duo)點(dian)觸摸(mo)(mo)的(de)中(zhong)心點(dian)判斷，因為電(dian)(dian)(dian)流疊加是(shi)分(fen)不(bu)出來誰(shui)是(shi)誰(shui)的(de)，沒有(you)辦法。
但是(shi)，目前(qian)來(lai)(lai)(lai)(lai)說，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)仍(reng)然(ran)有(you)不少問題存在(zai)(zai)。武漢(han)公司信為，觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)目前(qian)的(de)(de)(de)(de)(de)透(tou)明導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)材(cai)料ITO--氧(yang)化金屬(shu)非常(chang)(chang)脆弱，觸(chu)(chu)(chu)摸(mo)(mo)幾下(xia)就會損壞，還不能直(zhi)(zhi)接用(yong)來(lai)(lai)(lai)(lai)作工(gong)作層(ceng)。材(cai)料的(de)(de)(de)(de)(de)問題一(yi)(yi)時還難以解決(jue)，只好委曲求全：在(zai)(zai)外(wai)部增加一(yi)(yi)層(ceng)非常(chang)(chang)薄的(de)(de)(de)(de)(de)堅硬玻璃，它(ta)顯然(ran)是(shi)不能導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)，直(zhi)(zhi)流(liu)是(shi)不行了，改用(yong)高(gao)頻交流(liu)信號，靠人(ren)的(de)(de)(de)(de)(de)手指(zhi)頭（隔著薄玻璃）與工(gong)作面形成的(de)(de)(de)(de)(de)耦(ou)合(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容來(lai)(lai)(lai)(lai)吸走一(yi)(yi)個交流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，這就是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容屏(ping)"電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容"名字(zi)的(de)(de)(de)(de)(de)由(you)來(lai)(lai)(lai)(lai)。 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)之所以出(chu)現"漂(piao)(piao)移(yi)"的(de)(de)(de)(de)(de)問題，是(shi)因(yin)(yin)為耦(ou)合(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容的(de)(de)(de)(de)(de)方式(shi)是(shi)不穩(wen)(wen)定(ding)的(de)(de)(de)(de)(de)，它(ta)直(zhi)(zhi)接受溫度(du)、濕(shi)度(du)、手指(zhi)濕(shi)潤程(cheng)度(du)、人(ren)體(ti)體(ti)重、地面干(gan)燥程(cheng)度(du)影響(xiang)，受外(wai)界大(da)(da)面積物體(ti)的(de)(de)(de)(de)(de)干(gan)擾也(ye)非常(chang)(chang)大(da)(da)，帶(dai)來(lai)(lai)(lai)(lai)了不穩(wen)(wen)定(ding)的(de)(de)(de)(de)(de)結果，這些(xie)都直(zhi)(zhi)接違(wei)背了作為觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)這種坐(zuo)標(biao)系統的(de)(de)(de)(de)(de)基本(ben)要(yao)(yao)求，不可(ke)避免(mian)的(de)(de)(de)(de)(de)要(yao)(yao)產生(sheng)漂(piao)(piao)移(yi)，有(you)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)欲求通(tong)過25點校準(zhun)法甚(shen)至(zhi)96點校準(zhun)法來(lai)(lai)(lai)(lai)解決(jue)漂(piao)(piao)移(yi)問題，其(qi)實(shi)是(shi)不可(ke)能的(de)(de)(de)(de)(de)，漂(piao)(piao)移(yi)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容工(gong)作的(de)(de)(de)(de)(de)這種方式(shi)決(jue)定(ding)的(de)(de)(de)(de)(de)，即使(shi)是(shi)在(zai)(zai)控制(zhi)器的(de)(de)(de)(de)(de)單片程(cheng)序上(shang)利用(yong)動態計算(suan)(suan)和經驗值查表，也(ye)只能是(shi)治(zhi)標(biao)不治(zhi)本(ben)。 其(qi)實(shi)，多點校準(zhun)法最早是(shi)大(da)(da)屏(ping)幕投影觸(chu)(chu)(chu)摸(mo)(mo)板使(shi)用(yong)的(de)(de)(de)(de)(de)方法，目的(de)(de)(de)(de)(de)是(shi)消除坐(zuo)標(biao)對應的(de)(de)(de)(de)(de)線xing失真，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)的(de)(de)(de)(de)(de)線xing失真也(ye)非常(chang)(chang)厲害，主要(yao)(yao)是(shi)因(yin)(yin)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容屏(ping)的(de)(de)(de)(de)(de)計算(suan)(suan)建立(li)在(zai)(zai)四個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)量(liang)與觸(chu)(chu)(chu)摸(mo)(mo)點到四個電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)極的(de)(de)(de)(de)(de)距離(li)成比例(li)的(de)(de)(de)(de)(de)理想狀態上(shang)，實(shi)際(ji)由(you)于受環境電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容、線路寄生(sheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容和不同人(ren)使(shi)用(yong)的(de)(de)(de)(de)(de)影響(xiang)。
