教你如何選購一個適當的(de)觸摸屏

教你如何選購一(yi)個適(shi)當(dang)的(de)(de)觸摸屏(ping),觸摸屏(ping)在(zai)當(dang)今(jin)的(de)(de)新產(chan)品設計上是一(yi)項新的(de)(de)零件, 在(zai)這三年(nian)內(nei)有許(xu)多(duo)觸摸屏(ping)的(de)(de)工廠誕生(sheng), 使用者可能從外觀無法(fa)判別某一(yi)家生(sheng)產(chan)的(de)(de)觸摸屏(ping)品質好(hao)壞(huai), 我們在(zai)此提出(chu)一(yi)些簡(jian)單的(de)(de)方法(fa)可以由外觀上看出(chu)大略產(chan)品的(de)(de)品質。

另外(wai)市場上有(you)4線(xian)式、5線(xian)式、6線(xian)式和8線(xian)式的(de)(de)生(sheng)產廠商(shang), 到底那(nei)一種設計(ji)才符合我們的(de)(de)需要?當(dang)拿到一片觸摸屏時看一下(xia)觸摸屏的(de)(de)四周是否印(yin)有(you)綠色的(de)(de)邊框, 如果有(you)的(de)(de)話, 大概可以猜到是絕(jue)緣(yuan)油墨(mo), 但絕(jue)緣(yuan)油墨(mo)也可能是半透明(ming)的(de)(de)顏色。

不(bu)論(lun)如何, 采(cai)用絕緣油墨的(de)設計(ji)會(hui)比采(cai)用有(you)基材雙面膠(jiao)的(de)品(pin)質稍差(cha)。另外可(ke)(ke)以看(kan)(kan)一(yi)(yi)看(kan)(kan)出(chu)線(xian)端的(de)設計(ji),若出(chu)線(xian)尾巴連(lian)接的(de)地方與觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏本身(shen)粘的(de)力量(liang)不(bu)夠, 此觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏很容(rong)易就壞掉(diao)了,觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏若壞掉(diao)要(yao)修復的(de)機會(hui)不(bu)大(da)。再者可(ke)(ke)以將觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏拿在手(shou)上用60°角度(du)看(kan)(kan)一(yi)(yi)下(xia)(xia)表(biao)面是否(fou)有(you)牛頓環(huan)(huan)產生, 若有(you)牛頓環(huan)(huan)產生的(de)觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏, 表(biao)示此工廠在處(chu)理牛頓環(huan)(huan)問題經驗不(bu)夠。用手(shou)指(zhi)按觸(chu)(chu)(chu)(chu)(chu)(chu)觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏感(gan)覺一(yi)(yi)下(xia)(xia)是不(bu)是觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏有(you)上下(xia)(xia)二(er)層, 若感(gan)覺到則表(biao)示此工廠對提供一(yi)(yi)個(ge)良好品(pin)質的(de)觸(chu)(chu)(chu)(chu)(chu)(chu)摸(mo)(mo)屏產品(pin)還有(you)一(yi)(yi)段路(lu)要(yao)走。

再者, 我們根據不(bu)同的(de)(de)(de)(de)(de)(de)(de)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)設(she)計(ji)(ji)提供(gong)一(yi)(yi)(yi)些(xie)看法。 4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)設(she)計(ji)(ji)這(zhe)是(shi)最基本的(de)(de)(de)(de)(de)(de)(de)做法, 也是(shi)當今90%觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)工廠的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)(ji)主流(liu),因(yin)(yin)為將觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)X.Y軸的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路直(zhi)接拉出來(lai)(lai), 透過(guo)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)控制器轉換, 可讀到(dao)使用(yong)者觸(chu)(chu)摸(mo)(mo)(mo)的(de)(de)(de)(de)(de)(de)(de)位置。 4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)(ji)最好(hao)是(shi)用(yong)在(zai)小(xiao)(xiao)尺寸(cun)產(chan)(chan)品上(shang), 小(xiao)(xiao)尺寸(cun)指的(de)(de)(de)(de)(de)(de)(de)是(shi)10.4’’以(yi)(yi)下的(de)(de)(de)(de)(de)(de)(de)尺寸(cun), 因(yin)(yin)為觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)是(shi)靠(kao)表面(mian)電(dian)阻(zu)的(de)(de)(de)(de)(de)(de)(de)阻(zu)質(zhi)經加(jia)入電(dian)壓后轉算出觸(chu)(chu)摸(mo)(mo)(mo)的(de)(de)(de)(de)(de)(de)(de)位置, 表面(mian)電(dian)阻(zu)可能會因(yin)(yin)為環境或其它原因(yin)(yin)的(de)(de)(de)(de)(de)(de)(de)緣故產(chan)(chan)生老(lao)化現象(xiang)(xiang), 在(zai)小(xiao)(xiao)尺寸(cun)的(de)(de)(de)(de)(de)(de)(de)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)上(shang)不(bu)易被使用(yong)者感(gan)覺出來(lai)(lai), 4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)會是(shi)一(yi)(yi)(yi)個很好(hao)的(de)(de)(de)(de)(de)(de)(de)選擇。 8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping) 8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)則是(shi)可以(yi)(yi)彌補4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)設(she)計(ji)(ji)和(he)大(da)(da)尺寸(cun)發生的(de)(de)(de)(de)(de)(de)(de)現象(xiang)(xiang), 所以(yi)(yi)8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)在(zai)每一(yi)(yi)(yi)邊上(shang)設(she)計(ji)(ji)了一(yi)(yi)(yi)條“感(gan)應線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)”, 若(ruo)表面(mian)電(dian)阻(zu)發生老(lao)化現象(xiang)(xiang)可以(yi)(yi)靠(kao)感(gan)應線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)立刻(ke)調整回(hui)正常情況, 所以(yi)(yi)8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)(ji)對10.4”以(yi)(yi)上(shang)的(de)(de)(de)(de)(de)(de)(de)尺寸(cun)是(shi)一(yi)(yi)(yi)項最好(hao)的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)(ji)。 5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping): 5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)(ji)是(shi)指X,Y軸皆放(fang)在(zai)底層玻璃上(shang), 上(shang)面(mian)的(de)(de)(de)(de)(de)(de)(de)導電(dian)薄(bo)膜則只(zhi)是(shi)條感(gan)應線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian), 這(zhe)種(zhong)設(she)計(ji)(ji)只(zhi)能用(yong)在(zai)大(da)(da)尺寸(cun)上(shang), 因(yin)(yin)為四邊的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路區域要比(bi)8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)路來(lai)(lai)的(de)(de)(de)(de)(de)(de)(de)寬。一(yi)(yi)(yi)般5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping)價格比(bi)4線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)和(he)8線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)要高。 6線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)觸(chu)(chu)摸(mo)(mo)(mo)屏(ping) 6線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)是(shi)在(zai)5線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)式(shi)(shi)(shi)(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)(ji)再加(jia)上(shang)一(yi)(yi)(yi)條“地線(xian)(xian)(xian)(xian)(xian)(xian)(xian)(xian)”(Grounding)。
