電(dian)(dian)容觸(chu)摸(mo)屏(ping)的(de)漂移問題(ti)。在(zai)觸(chu)摸(mo)屏(ping)產(chan)品(pin)(pin)中，電(dian)(dian)容觸(chu)摸(mo)屏(ping)是我們(men)常用的(de)觸(chu)摸(mo)屏(ping)方(fang)式，那(nei)么(me)，對于(yu)(yu)電(dian)(dian)容觸(chu)摸(mo)屏(ping)來說，其產(chan)品(pin)(pin)本身應用比較廣泛，但是也(ye)存(cun)在(zai)著不少(shao)問題(ti)。而(er)且(qie)由于(yu)(yu)現(xian)在(zai)科技的(de)發(fa)展程度(du)還無法完全解決觸(chu)摸(mo)屏(ping)產(chan)品(pin)(pin)在(zai)相關原理上(shang)出現(xian)的(de)問題(ti)，所(suo)以(yi)對于(yu)(yu)這些(xie)問題(ti)，目前還是普遍存(cun)在(zai)的(de)。
在這里武漢(han)公司要跟(gen)大家討論的(de)是(shi)(shi)關于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)的(de)"漂移"問題，這個(ge)問題比(bi)較常見，也是(shi)(shi)我們在解決產品問題時主要考慮的(de)方面(mian)。 電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)的(de)漂移問題介紹！ 武漢(han)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)公司提示，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)本身實際是(shi)(shi)一套(tao)精密的(de)漏(lou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)傳感(gan)器，帶手套(tao)的(de)手不能觸(chu)(chu)摸(mo)(mo)(mo)，由于(yu)(yu)使用電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)方式(shi)，導(dao)致有漂移現象。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)都是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)原(yuan)理工作(zuo)方式(shi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)工作(zuo)方式(shi)對于(yu)(yu)多點(dian)觸(chu)(chu)摸(mo)(mo)(mo)，不管是(shi)(shi)多少點(dian)，也不管是(shi)(shi)連續的(de)還是(shi)(shi)不連續的(de)都是(shi)(shi)取多點(dian)觸(chu)(chu)摸(mo)(mo)(mo)的(de)中心點(dian)判斷，因為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)疊加是(shi)(shi)分(fen)不出來誰是(shi)(shi)誰的(de)，沒(mei)有辦法。
但(dan)是(shi)(shi)(shi)，目前(qian)來說，電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)仍(reng)然有不(bu)(bu)(bu)少(shao)問題(ti)存(cun)在(zai)。武(wu)漢公(gong)司(si)信(xin)為(wei)，觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)目前(qian)的(de)(de)(de)(de)(de)(de)(de)透明導(dao)電(dian)(dian)材料ITO--氧化金屬非(fei)(fei)常脆弱，觸(chu)(chu)(chu)摸(mo)(mo)幾下就(jiu)會(hui)損壞(huai)，還不(bu)(bu)(bu)能直接(jie)用(yong)來作(zuo)(zuo)工作(zuo)(zuo)層。材料的(de)(de)(de)(de)(de)(de)(de)問題(ti)一時還難以(yi)解(jie)決(jue)，只好委曲求全：在(zai)外(wai)部增加一層非(fei)(fei)常薄的(de)(de)(de)(de)(de)(de)(de)堅硬玻璃(li)(li)，它(ta)顯然是(shi)(shi)(shi)不(bu)(bu)(bu)能導(dao)電(dian)(dian)的(de)(de)(de)(de)(de)(de)(de)，直流(liu)是(shi)(shi)(shi)不(bu)(bu)(bu)行了(le)，改用(yong)高頻(pin)交流(liu)信(xin)號，靠人的(de)(de)(de)(de)(de)(de)(de)手(shou)指頭（隔(ge)著(zhu)薄玻璃(li)(li)）與(yu)工作(zuo)(zuo)面形成的(de)(de)(de)(de)(de)(de)(de)耦合(he)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)來吸走一個交流(liu)電(dian)(dian)流(liu)，這(zhe)就(jiu)是(shi)(shi)(shi)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)屏(ping)"電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)"名(ming)字(zi)的(de)(de)(de)(de)(de)(de)(de)由(you)(you)來。 電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)之所以(yi)出(chu)現(xian)"漂(piao)移(yi)"的(de)(de)(de)(de)(de)(de)(de)問題(ti)，是(shi)(shi)(shi)因為(wei)耦合(he)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)的(de)(de)(de)(de)(de)(de)(de)方(fang)式是(shi)(shi)(shi)不(bu)(bu)(bu)穩定(ding)(ding)的(de)(de)(de)(de)(de)(de)(de)，它(ta)直接(jie)受溫度(du)、濕度(du)、手(shou)指濕潤程度(du)、人體(ti)(ti)體(ti)(ti)重、地面干燥程度(du)影(ying)響，受外(wai)界大面積物體(ti)(ti)的(de)(de)(de)(de)(de)(de)(de)干擾(rao)也非(fei)(fei)常大，帶來了(le)不(bu)(bu)(bu)穩定(ding)(ding)的(de)(de)(de)(de)(de)(de)(de)結(jie)果，這(zhe)些(xie)都直接(jie)違背了(le)作(zuo)(zuo)為(wei)觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)這(zhe)種坐標系統(tong)的(de)(de)(de)(de)(de)(de)(de)基本要(yao)(yao)求，不(bu)(bu)(bu)可避(bi)免的(de)(de)(de)(de)(de)(de)(de)要(yao)(yao)產生(sheng)漂(piao)移(yi)，有的(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)欲(yu)求通(tong)過25點校(xiao)準法(fa)(fa)甚(shen)至96點校(xiao)準法(fa)(fa)來解(jie)決(jue)漂(piao)移(yi)問題(ti)，其實(shi)是(shi)(shi)(shi)不(bu)(bu)(bu)可能的(de)(de)(de)(de)(de)(de)(de)，漂(piao)移(yi)是(shi)(shi)(shi)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)工作(zuo)(zuo)的(de)(de)(de)(de)(de)(de)(de)這(zhe)種方(fang)式決(jue)定(ding)(ding)的(de)(de)(de)(de)(de)(de)(de)，即(ji)使是(shi)(shi)(shi)在(zai)控制器的(de)(de)(de)(de)(de)(de)(de)單片程序上利用(yong)動態(tai)計(ji)(ji)算(suan)和經驗值查表，也只能是(shi)(shi)(shi)治(zhi)(zhi)標不(bu)(bu)(bu)治(zhi)(zhi)本。 其實(shi)，多點校(xiao)準法(fa)(fa)最早是(shi)(shi)(shi)大屏(ping)幕投影(ying)觸(chu)(chu)(chu)摸(mo)(mo)板使用(yong)的(de)(de)(de)(de)(de)(de)(de)方(fang)法(fa)(fa)，目的(de)(de)(de)(de)(de)(de)(de)是(shi)(shi)(shi)消除(chu)坐標對應(ying)的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)xing失(shi)真，電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)屏(ping)的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)xing失(shi)真也非(fei)(fei)常厲害，主要(yao)(yao)是(shi)(shi)(shi)因為(wei)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)屏(ping)的(de)(de)(de)(de)(de)(de)(de)計(ji)(ji)算(suan)建立在(zai)四個電(dian)(dian)流(liu)量與(yu)觸(chu)(chu)(chu)摸(mo)(mo)點到四個電(dian)(dian)極的(de)(de)(de)(de)(de)(de)(de)距離成比例的(de)(de)(de)(de)(de)(de)(de)理想(xiang)狀態(tai)上，實(shi)際由(you)(you)于受環境電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)、線(xian)(xian)路寄(ji)生(sheng)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)和不(bu)(bu)(bu)同人使用(yong)的(de)(de)(de)(de)(de)(de)(de)影(ying)響。
