教(jiao)你如何選購一個適(shi)當的觸摸屏

教你如何選購(gou)一(yi)個適當(dang)的觸(chu)摸(mo)(mo)(mo)屏,觸(chu)摸(mo)(mo)(mo)屏在當(dang)今的新產(chan)品設計上是(shi)一(yi)項新的零件, 在這三年內(nei)有許多觸(chu)摸(mo)(mo)(mo)屏的工廠(chang)誕生, 使用者可能(neng)從(cong)外觀(guan)無(wu)法(fa)判別某一(yi)家生產(chan)的觸(chu)摸(mo)(mo)(mo)屏品質好壞, 我們在此提(ti)出一(yi)些簡單的方法(fa)可以由(you)外觀(guan)上看出大略產(chan)品的品質。

另外市(shi)場上有4線(xian)式、5線(xian)式、6線(xian)式和8線(xian)式的(de)(de)生產(chan)廠(chang)商(shang), 到(dao)底(di)那一種設計(ji)才符(fu)合我們的(de)(de)需要?當拿到(dao)一片觸摸屏時看一下觸摸屏的(de)(de)四周是否(fou)印有綠色的(de)(de)邊框, 如果有的(de)(de)話, 大(da)概(gai)可以猜到(dao)是絕緣(yuan)油墨, 但絕緣(yuan)油墨也可能是半透明的(de)(de)顏色。

不(bu)(bu)論如(ru)何, 采(cai)用絕緣油墨(mo)的(de)設計會(hui)比采(cai)用有基材雙面(mian)膠的(de)品(pin)(pin)質稍差(cha)。另(ling)外可以(yi)(yi)看一看出線端的(de)設計,若(ruo)(ruo)出線尾(wei)巴連接(jie)的(de)地方與觸(chu)摸(mo)屏(ping)(ping)(ping)本身(shen)粘的(de)力量不(bu)(bu)夠, 此(ci)觸(chu)摸(mo)屏(ping)(ping)(ping)很容易(yi)就壞掉了,觸(chu)摸(mo)屏(ping)(ping)(ping)若(ruo)(ruo)壞掉要修復的(de)機(ji)會(hui)不(bu)(bu)大。再者可以(yi)(yi)將(jiang)觸(chu)摸(mo)屏(ping)(ping)(ping)拿在手上(shang)用60°角度看一下表(biao)面(mian)是否(fou)有牛(niu)頓環(huan)產生, 若(ruo)(ruo)有牛(niu)頓環(huan)產生的(de)觸(chu)摸(mo)屏(ping)(ping)(ping), 表(biao)示此(ci)工廠在處理牛(niu)頓環(huan)問題經驗(yan)不(bu)(bu)夠。用手指按(an)觸(chu)觸(chu)摸(mo)屏(ping)(ping)(ping)感覺(jue)一下是不(bu)(bu)是觸(chu)摸(mo)屏(ping)(ping)(ping)有上(shang)下二(er)層, 若(ruo)(ruo)感覺(jue)到(dao)則表(biao)示此(ci)工廠對提供一個良好品(pin)(pin)質的(de)觸(chu)摸(mo)屏(ping)(ping)(ping)產品(pin)(pin)還有一段路要走。

再者(zhe), 我們(men)根據不(bu)(bu)同的(de)(de)(de)觸(chu)摸(mo)(mo)屏(ping)(ping)設(she)(she)(she)計(ji)(ji)提供一些看法(fa)。 4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)設(she)(she)(she)計(ji)(ji)這是(shi)(shi)(shi)(shi)最(zui)基(ji)本的(de)(de)(de)做(zuo)法(fa), 也是(shi)(shi)(shi)(shi)當今(jin)90%觸(chu)摸(mo)(mo)屏(ping)(ping)工廠(chang)的(de)(de)(de)設(she)(she)(she)計(ji)(ji)主(zhu)流(liu),因為(wei)將觸(chu)摸(mo)(mo)屏(ping)(ping)X.Y軸的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)直接拉出(chu)來, 透過觸(chu)摸(mo)(mo)屏(ping)(ping)控制(zhi)器(qi)轉換, 可(ke)(ke)讀到使(shi)(shi)用者(zhe)觸(chu)摸(mo)(mo)的(de)(de)(de)位置(zhi)(zhi)。 4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)的(de)(de)(de)設(she)(she)(she)計(ji)(ji)最(zui)好是(shi)(shi)(shi)(shi)用在(zai)(zai)小(xiao)(xiao)尺(chi)寸(cun)(cun)產(chan)品上, 小(xiao)(xiao)尺(chi)寸(cun)(cun)指的(de)(de)(de)是(shi)(shi)(shi)(shi)10.4’’以(yi)(yi)(yi)下(xia)的(de)(de)(de)尺(chi)寸(cun)(cun), 因為(wei)觸(chu)摸(mo)(mo)屏(ping)(ping)是(shi)(shi)(shi)(shi)靠表面(mian)電(dian)阻的(de)(de)(de)阻質(zhi)經加入(ru)電(dian)壓后轉算(suan)出(chu)觸(chu)摸(mo)(mo)的(de)(de)(de)位置(zhi)(zhi), 表面(mian)電(dian)阻可(ke)(ke)能會因為(wei)環境或其(qi)它原因的(de)(de)(de)緣故產(chan)生(sheng)老化(hua)現象(xiang), 在(zai)(zai)小(xiao)(xiao)尺(chi)寸(cun)(cun)的(de)(de)(de)觸(chu)摸(mo)(mo)屏(ping)(ping)上不(bu)(bu)易被使(shi)(shi)用者(zhe)感覺(jue)出(chu)來, 4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping)會是(shi)(shi)(shi)(shi)一個很好的(de)(de)(de)選擇。 8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping) 8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping)則是(shi)(shi)(shi)(shi)可(ke)(ke)以(yi)(yi)(yi)彌補4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping)設(she)(she)(she)計(ji)(ji)和大尺(chi)寸(cun)(cun)發生(sheng)的(de)(de)(de)現象(xiang), 所以(yi)(yi)(yi)8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping)在(zai)(zai)每(mei)一邊上設(she)(she)(she)計(ji)(ji)了一條“感應(ying)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)”, 若表面(mian)電(dian)阻發生(sheng)老化(hua)現象(xiang)可(ke)(ke)以(yi)(yi)(yi)靠感應(ying)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)立刻調整(zheng)回(hui)正(zheng)常情況, 所以(yi)(yi)(yi)8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)的(de)(de)(de)設(she)(she)(she)計(ji)(ji)對10.4”以(yi)(yi)(yi)上的(de)(de)(de)尺(chi)寸(cun)(cun)是(shi)(shi)(shi)(shi)一項最(zui)好的(de)(de)(de)設(she)(she)(she)計(ji)(ji)。 5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping): 5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)的(de)(de)(de)設(she)(she)(she)計(ji)(ji)是(shi)(shi)(shi)(shi)指X,Y軸皆放在(zai)(zai)底層玻璃上, 上面(mian)的(de)(de)(de)導電(dian)薄(bo)膜(mo)則只是(shi)(shi)(shi)(shi)條感應(ying)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian), 這種設(she)(she)(she)計(ji)(ji)只能用在(zai)(zai)大尺(chi)寸(cun)(cun)上, 因為(wei)四(si)邊的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)區域(yu)要比8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)的(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路(lu)來的(de)(de)(de)寬。一般5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)的(de)(de)(de)觸(chu)摸(mo)(mo)屏(ping)(ping)價格比4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)和8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)要高。 6線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)觸(chu)摸(mo)(mo)屏(ping)(ping) 6線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)是(shi)(shi)(shi)(shi)在(zai)(zai)5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)的(de)(de)(de)設(she)(she)(she)計(ji)(ji)再加上一條“地線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)”(Grounding)。
