電容(rong)觸(chu)摸(mo)(mo)屏的(de)漂移問題。在(zai)(zai)(zai)觸(chu)摸(mo)(mo)屏產品(pin)中,電容(rong)觸(chu)摸(mo)(mo)屏是我們常用(yong)的(de)觸(chu)摸(mo)(mo)屏方式,那么(me),對(dui)于(yu)電容(rong)觸(chu)摸(mo)(mo)屏來說,其產品(pin)本身應用(yong)比(bi)較(jiao)廣(guang)泛(fan),但是也存(cun)在(zai)(zai)(zai)著不少問題。而且由(you)于(yu)現在(zai)(zai)(zai)科技的(de)發展(zhan)程度(du)還無法完(wan)全解決觸(chu)摸(mo)(mo)屏產品(pin)在(zai)(zai)(zai)相關原理上出現的(de)問題,所以對(dui)于(yu)這些(xie)問題,目前還是普遍存(cun)在(zai)(zai)(zai)的(de)。

在這里武漢公司(si)要(yao)跟大家(jia)討論的(de)(de)是(shi)(shi)(shi)(shi)關于(yu)電(dian)容(rong)觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)的(de)(de)"漂(piao)移"問題(ti),這個問題(ti)比較常見,也是(shi)(shi)(shi)(shi)我們在解(jie)決產(chan)品問題(ti)時主要(yao)考慮的(de)(de)方面。    電(dian)容(rong)觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)的(de)(de)漂(piao)移問題(ti)介紹!    武漢觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)公司(si)提示,電(dian)容(rong)觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)本身實際是(shi)(shi)(shi)(shi)一套精密的(de)(de)漏(lou)電(dian)傳感器,帶手套的(de)(de)手不(bu)能觸(chu)(chu)摸(mo)(mo),由于(yu)使用電(dian)容(rong)方式,導致(zhi)有(you)漂(piao)移現象。電(dian)容(rong)觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)和電(dian)阻觸(chu)(chu)摸(mo)(mo)屏(ping)(ping)都是(shi)(shi)(shi)(shi)電(dian)原理工作方式,電(dian)工作方式對(dui)于(yu)多點(dian)觸(chu)(chu)摸(mo)(mo),不(bu)管(guan)是(shi)(shi)(shi)(shi)多少(shao)點(dian),也不(bu)管(guan)是(shi)(shi)(shi)(shi)連續的(de)(de)還是(shi)(shi)(shi)(shi)不(bu)連續的(de)(de)都是(shi)(shi)(shi)(shi)取多點(dian)觸(chu)(chu)摸(mo)(mo)的(de)(de)中心點(dian)判(pan)斷,因為(wei)電(dian)流疊加是(shi)(shi)(shi)(shi)分(fen)不(bu)出來誰是(shi)(shi)(shi)(shi)誰的(de)(de),沒有(you)辦法。

但是(shi)(shi)(shi),目(mu)前(qian)來(lai)說,電(dian)(dian)(dian)容(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)仍(reng)然有(you)不(bu)少問(wen)題(ti)存在(zai)。武漢(han)公司(si)信(xin)為,觸(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)目(mu)前(qian)的(de)(de)(de)(de)(de)(de)透明導電(dian)(dian)(dian)材料(liao)ITO--氧化金屬非常(chang)脆弱,觸(chu)(chu)(chu)摸(mo)(mo)(mo)幾(ji)下就會損壞(huai),還不(bu)能(neng)直(zhi)(zhi)接(jie)用來(lai)作(zuo)工(gong)(gong)作(zuo)層(ceng)。材料(liao)的(de)(de)(de)(de)(de)(de)問(wen)題(ti)一(yi)時還難以解決,只好(hao)委曲求全:在(zai)外(wai)部增加一(yi)層(ceng)非常(chang)薄的(de)(de)(de)(de)(de)(de)堅硬玻璃(li),它(ta)顯然是(shi)(shi)(shi)不(bu)能(neng)導電(dian)(dian)(dian)的(de)(de)(de)(de)(de)(de),直(zhi)(zhi)流(liu)是(shi)(shi)(shi)不(bu)行(xing)了(le),改(gai)用高頻交流(liu)信(xin)號,靠(kao)人(ren)的(de)(de)(de)(de)(de)(de)手指頭(隔著薄玻璃(li))與工(gong)(gong)作(zuo)面形(xing)成的(de)(de)(de)(de)(de)(de)耦(ou)合(he)電(dian)(dian)(dian)容(rong)(rong)(rong)來(lai)吸走一(yi)個(ge)交流(liu)電(dian)(dian)(dian)流(liu),這(zhe)就是(shi)(shi)(shi)電(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)"電(dian)(dian)(dian)容(rong)(rong)(rong)"名(ming)字的(de)(de)(de)(de)(de)(de)由來(lai)。    電(dian)(dian)(dian)容(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)之(zhi)所以出現"漂(piao)(piao)移"的(de)(de)(de)(de)(de)(de)問(wen)題(ti),是(shi)(shi)(shi)因(yin)為耦(ou)合(he)電(dian)(dian)(dian)容(rong)(rong)(rong)的(de)(de)(de)(de)(de)(de)方式(shi)是(shi)(shi)(shi)不(bu)穩(wen)(wen)定(ding)(ding)的(de)(de)(de)(de)(de)(de),它(ta)直(zhi)(zhi)接(jie)受(shou)溫(wen)度(du)(du)、濕度(du)(du)、手指濕潤(run)程(cheng)(cheng)度(du)(du)、人(ren)體體重、地面干(gan)燥程(cheng)(cheng)度(du)(du)影響(xiang),受(shou)外(wai)界大(da)面積物體的(de)(de)(de)(de)(de)(de)干(gan)擾也非常(chang)大(da),帶來(lai)了(le)不(bu)穩(wen)(wen)定(ding)(ding)的(de)(de)(de)(de)(de)(de)結果,這(zhe)些都直(zhi)(zhi)接(jie)違背了(le)作(zuo)為觸(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)這(zhe)種坐標(biao)(biao)系統的(de)(de)(de)(de)(de)(de)基本(ben)要求,不(bu)可避免的(de)(de)(de)(de)(de)(de)要產生漂(piao)(piao)移,有(you)的(de)(de)(de)(de)(de)(de)電(dian)(dian)(dian)容(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)欲求通過25點(dian)校準(zhun)法甚至96點(dian)校準(zhun)法來(lai)解決漂(piao)(piao)移問(wen)題(ti),其實是(shi)(shi)(shi)不(bu)可能(neng)的(de)(de)(de)(de)(de)(de),漂(piao)(piao)移是(shi)(shi)(shi)電(dian)(dian)(dian)容(rong)(rong)(rong)工(gong)(gong)作(zuo)的(de)(de)(de)(de)(de)(de)這(zhe)種方式(shi)決定(ding)(ding)的(de)(de)(de)(de)(de)(de),即使(shi)是(shi)(shi)(shi)在(zai)控制器的(de)(de)(de)(de)(de)(de)單片程(cheng)(cheng)序上(shang)利用動(dong)態(tai)計(ji)(ji)算和經驗(yan)值(zhi)查表,也只能(neng)是(shi)(shi)(shi)治標(biao)(biao)不(bu)治本(ben)。    其實,多點(dian)校準(zhun)法最早是(shi)(shi)(shi)大(da)屏(ping)幕投(tou)影觸(chu)(chu)(chu)摸(mo)(mo)(mo)板使(shi)用的(de)(de)(de)(de)(de)(de)方法,目(mu)的(de)(de)(de)(de)(de)(de)是(shi)(shi)(shi)消(xiao)除坐標(biao)(biao)對應的(de)(de)(de)(de)(de)(de)線xing失真(zhen),電(dian)(dian)(dian)容(rong)(rong)(rong)觸(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)的(de)(de)(de)(de)(de)(de)線xing失真(zhen)也非常(chang)厲害(hai),主要是(shi)(shi)(shi)因(yin)為電(dian)(dian)(dian)容(rong)(rong)(rong)屏(ping)的(de)(de)(de)(de)(de)(de)計(ji)(ji)算建立在(zai)四個(ge)電(dian)(dian)(dian)流(liu)量與觸(chu)(chu)(chu)摸(mo)(mo)(mo)點(dian)到四個(ge)電(dian)(dian)(dian)極的(de)(de)(de)(de)(de)(de)距(ju)離成比例的(de)(de)(de)(de)(de)(de)理想狀(zhuang)態(tai)上(shang),實際由于受(shou)環境電(dian)(dian)(dian)容(rong)(rong)(rong)、線路寄生電(dian)(dian)(dian)容(rong)(rong)(rong)和不(bu)同人(ren)使(shi)用的(de)(de)(de)(de)(de)(de)影響(xiang)。
