觸摸屏(ping)(ping)板的工作(zuo)原(yuan)理(li) 觸摸屏(ping)(ping)板的種類(lei)

1、觸摸屏板的工作原理

從技(ji)術(shu)原(yuan)理(li)來(lai)區別觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)，可分(fen)為(wei)五個基本種(zhong)類(lei)：矢量壓(ya)力傳感技(ji)術(shu)觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)、電阻技(ji)術(shu)觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)、電容(rong)(rong)(rong)技(ji)術(shu)觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)、紅(hong)外(wai)(wai)線(xian)技(ji)術(shu)觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)、表面(mian)聲波技(ji)術(shu)觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)。其中矢量壓(ya)力傳感技(ji)術(shu)觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)已退出歷史舞臺。觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)紅(hong)外(wai)(wai)屏(ping)(ping)(ping)(ping)價(jia)格低廉，但其外(wai)(wai)框易碎，容(rong)(rong)(rong)易產生光干擾(rao)，曲面(mian)情況下失(shi)真；電容(rong)(rong)(rong)屏(ping)(ping)(ping)(ping)設計理(li)論(lun)好，但其圖象失(shi)真問題很難得到(dao)根本解(jie)決(jue)；電阻屏(ping)(ping)(ping)(ping)的(de)(de)定位準確，但其價(jia)格頗高，且怕刮易損。表面(mian)聲波觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)解(jie)決(jue)了以往觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)的(de)(de)各種(zhong)缺(que)陷，清(qing)晰(xi)抗暴，適(shi)于各種(zhong)場合，缺(que)憾是(shi)屏(ping)(ping)(ping)(ping)表面(mian)的(de)(de)水滴、塵土會使觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)變的(de)(de)遲鈍，甚至不工作(zuo)。按照觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)的(de)(de)工作(zuo)原(yuan)理(li)和傳輸信息(xi)的(de)(de)介(jie)質，我們(men)把觸(chu)(chu)(chu)(chu)摸(mo)(mo)(mo)屏(ping)(ping)(ping)(ping)分(fen)為(wei)四種(zhong)，它們(men)分(fen)別為(wei)電阻式(shi)、紅(hong)外(wai)(wai)線(xian)式(shi)、電容(rong)(rong)(rong)感應式(shi)以及表面(mian)聲波式(shi)。

（1）電阻觸摸屏

電(dian)(dian)阻觸摸屏的屏體部(bu)分是一(yi)塊與顯示(shi)器表面相(xiang)匹(pi)配的多層(ceng)復(fu)合(he)薄膜，由一(yi)層(ceng)玻璃或有(you)機玻璃作為基層(ceng)，表面涂有(you)一(yi)層(ceng)透(tou)(tou)明(ming)的導電(dian)(dian)層(ceng)，上面再蓋有(you)一(yi)層(ceng)外表面硬化處理、光(guang)滑(hua)防刮的塑料層(ceng)，它(ta)的內(nei)表面也涂有(you)一(yi)層(ceng)透(tou)(tou)明(ming)導電(dian)(dian)層(ceng)，在兩層(ceng)導電(dian)(dian)層(ceng)之(zhi)間有(you)許(xu)多細小(小于千分之(zhi)一(yi)英(ying)寸(cun))的透(tou)(tou)明(ming)隔離點把(ba)它(ta)們隔開絕(jue)緣。

當手指觸(chu)(chu)(chu)摸(mo)屏幕(mu)時，平常相互(hu)絕緣的(de)(de)兩(liang)(liang)層(ceng)(ceng)(ceng)(ceng)導(dao)(dao)電(dian)(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)就(jiu)在(zai)觸(chu)(chu)(chu)摸(mo)點(dian)位(wei)置(zhi)有了一(yi)個接(jie)觸(chu)(chu)(chu)，因其中一(yi)面(mian)導(dao)(dao)電(dian)(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)接(jie)通Y軸方向的(de)(de)均勻電(dian)(dian)(dian)(dian)壓(ya)場(chang)，使得偵測層(ceng)(ceng)(ceng)(ceng)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)由零變(bian)為非零，這(zhe)種接(jie)通狀態被控制器偵測到(dao)(dao)后，進行A／D轉換(huan)，并將得到(dao)(dao)的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)值與基準相比即(ji)可得到(dao)(dao)觸(chu)(chu)(chu)摸(mo)點(dian)的(de)(de)Y軸坐(zuo)標(biao)，同(tong)理(li)得出(chu)X軸的(de)(de)坐(zuo)標(biao)，這(zhe)就(jiu)是所有電(dian)(dian)(dian)(dian)阻(zu)技(ji)術觸(chu)(chu)(chu)摸(mo)屏共同(tong)的(de)(de)最基本原理(li)。電(dian)(dian)(dian)(dian)阻(zu)類(lei)觸(chu)(chu)(chu)摸(mo)屏的(de)(de)關鍵在(zai)于材料(liao)科技(ji)。電(dian)(dian)(dian)(dian)阻(zu)屏根據引出(chu)線(xian)(xian)數多(duo)少，分為四線(xian)(xian)、五線(xian)(xian)、六線(xian)(xian)等多(duo)線(xian)(xian)電(dian)(dian)(dian)(dian)阻(zu)觸(chu)(chu)(chu)摸(mo)屏。電(dian)(dian)(dian)(dian)阻(zu)式(shi)觸(chu)(chu)(chu)摸(mo)屏在(zai)強化玻璃表面(mian)分別涂上兩(liang)(liang)層(ceng)(ceng)(ceng)(ceng)OTI透明(ming)氧化金屬導(dao)(dao)電(dian)(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)，最外面(mian)的(de)(de)一(yi)層(ceng)(ceng)(ceng)(ceng)OTI涂層(ceng)(ceng)(ceng)(ceng)作為導(dao)(dao)電(dian)(dian)(dian)(dian)體，第二層(ceng)(ceng)(ceng)(ceng)OTI則(ze)經過精密的(de)(de)網絡附上橫(heng)豎兩(liang)(liang)個方向的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)場(chang)，兩(liang)(liang)層(ceng)(ceng)(ceng)(ceng)OTI之間以細(xi)小的(de)(de)透明(ming)隔離點(dian)隔開。當手指接(jie)觸(chu)(chu)(chu)屏幕(mu)時，兩(liang)(liang)層(ceng)(ceng)(ceng)(ceng)OTI導(dao)(dao)電(dian)(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)就(jiu)會(hui)出(chu)現一(yi)個接(jie)觸(chu)(chu)(chu)點(dian)，電(dian)(dian)(dian)(dian)腦(nao)同(tong)時檢測電(dian)(dian)(dian)(dian)壓(ya)及電(dian)(dian)(dian)(dian)流，計算出(chu)觸(chu)(chu)(chu)摸(mo)的(de)(de)位(wei)置(zhi)，反應速度(du)為10-20ms。

五線電(dian)(dian)(dian)阻觸摸屏的(de)(de)外層(ceng)(ceng)(ceng)(ceng)導(dao)電(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)使(shi)用的(de)(de)是延(yan)(yan)展(zhan)(zhan)(zhan)性(xing)好的(de)(de)鎳金(jin)涂層(ceng)(ceng)(ceng)(ceng)材料，外導(dao)電(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)由(you)于頻繁觸摸，使(shi)用延(yan)(yan)展(zhan)(zhan)(zhan)性(xing)好的(de)(de)鎳金(jin)材料目(mu)的(de)(de)是為(wei)了延(yan)(yan)長使(shi)用壽命，但(dan)是工(gong)藝成本較為(wei)高昂。鎳金(jin)導(dao)電(dian)(dian)(dian)層(ceng)(ceng)(ceng)(ceng)雖然延(yan)(yan)展(zhan)(zhan)(zhan)性(xing)好，但(dan)是只(zhi)能作(zuo)(zuo)透明(ming)導(dao)體，不(bu)適(shi)合作(zuo)(zuo)為(wei)電(dian)(dian)(dian)阻觸控屏的(de)(de)工(gong)作(zuo)(zuo)面，因(yin)為(wei)它導(dao)電(dian)(dian)(dian)率高，而且金(jin)屬(shu)不(bu)易(yi)做到厚度非(fei)常均勻，不(bu)宜作(zuo)(zuo)電(dian)(dian)(dian)壓分布層(ceng)(ceng)(ceng)(ceng)，只(zhi)能作(zuo)(zuo)為(wei)探(tan)層(ceng)(ceng)(ceng)(ceng)。

電(dian)(dian)(dian)阻觸(chu)(chu)摸(mo)屏(ping)是一種對(dui)外(wai)(wai)(wai)界完(wan)全隔離的(de)工作環(huan)境，不怕(pa)灰塵和水汽，它(ta)可(ke)(ke)(ke)以(yi)用(yong)任(ren)何物體來(lai)觸(chu)(chu)摸(mo),可(ke)(ke)(ke)以(yi)用(yong)來(lai)寫字畫畫，比較適合工業控制領域及辦(ban)公室內有限(xian)人的(de)使(shi)用(yong)。電(dian)(dian)(dian)阻觸(chu)(chu)摸(mo)屏(ping)共同的(de)缺點是因為(wei)復合薄膜的(de)外(wai)(wai)(wai)層采用(yong)塑膠材(cai)料,不知道的(de)人太用(yong)力或使(shi)用(yong)銳器觸(chu)(chu)摸(mo)可(ke)(ke)(ke)能(neng)劃(hua)傷(shang)整(zheng)個觸(chu)(chu)控屏(ping)而導致(zhi)報(bao)廢。不過,在限(xian)度之內，劃(hua)傷(shang)只會(hui)傷(shang)及外(wai)(wai)(wai)導電(dian)(dian)(dian)層，外(wai)(wai)(wai)導電(dian)(dian)(dian)層的(de)劃(hua)傷(shang)對(dui)于五線電(dian)(dian)(dian)阻觸(chu)(chu)摸(mo)屏(ping)來(lai)說沒有關系,而對(dui)四(si)線電(dian)(dian)(dian)阻觸(chu)(chu)摸(mo)屏(ping)來(lai)說是致(zhi)命的(de)。

（2）電容技術觸摸屏：

是(shi)(shi)利用(yong)人體(ti)的(de)(de)電(dian)(dian)流(liu)感應進行工作(zuo)的(de)(de)。電(dian)(dian)容(rong)(rong)式觸(chu)摸(mo)屏(ping)(ping)(ping)是(shi)(shi)是(shi)(shi)一(yi)塊四(si)(si)層(ceng)(ceng)(ceng)(ceng)(ceng)復(fu)合(he)玻璃屏(ping)(ping)(ping)，玻璃屏(ping)(ping)(ping)的(de)(de)內表面和(he)(he)夾(jia)層(ceng)(ceng)(ceng)(ceng)(ceng)各涂(tu)有一(yi)層(ceng)(ceng)(ceng)(ceng)(ceng)ITO，最外(wai)層(ceng)(ceng)(ceng)(ceng)(ceng)是(shi)(shi)一(yi)薄層(ceng)(ceng)(ceng)(ceng)(ceng)矽土玻璃保護層(ceng)(ceng)(ceng)(ceng)(ceng),夾(jia)層(ceng)(ceng)(ceng)(ceng)(ceng)ITO涂(tu)層(ceng)(ceng)(ceng)(ceng)(ceng)作(zuo)為工作(zuo)面,四(si)(si)個(ge)(ge)角上(shang)引出(chu)四(si)(si)個(ge)(ge)電(dian)(dian)極，內層(ceng)(ceng)(ceng)(ceng)(ceng)ITO為屏(ping)(ping)(ping)蔽層(ceng)(ceng)(ceng)(ceng)(ceng)以保證(zheng)良好的(de)(de)工作(zuo)環境。當(dang)手(shou)指(zhi)觸(chu)摸(mo)在金(jin)屬層(ceng)(ceng)(ceng)(ceng)(ceng)上(shang)時，由于人體(ti)電(dian)(dian)場，用(yong)戶(hu)和(he)(he)觸(chu)控(kong)屏(ping)(ping)(ping)表面形(xing)成以一(yi)個(ge)(ge)耦合(he)電(dian)(dian)容(rong)(rong)，對(dui)于高頻電(dian)(dian)流(liu)來說，電(dian)(dian)容(rong)(rong)是(shi)(shi)直接導體(ti)，于是(shi)(shi)手(shou)指(zhi)從接觸(chu)點吸走一(yi)個(ge)(ge)很(hen)小的(de)(de)電(dian)(dian)流(liu)。這個(ge)(ge)電(dian)(dian)流(liu)分從觸(chu)控(kong)屏(ping)(ping)(ping)的(de)(de)四(si)(si)角上(shang)的(de)(de)電(dian)(dian)極中流(liu)出(chu)，并且(qie)流(liu)經這四(si)(si)個(ge)(ge)電(dian)(dian)極的(de)(de)電(dian)(dian)流(liu)與手(shou)指(zhi)到(dao)四(si)(si)角的(de)(de)距離成正比，控(kong)制器(qi)通(tong)過對(dui)這四(si)(si)個(ge)(ge)電(dian)(dian)流(liu)比例的(de)(de)精(jing)確計算，得出(chu)觸(chu)摸(mo)點的(de)(de)位置。電(dian)(dian)容(rong)(rong)觸(chu)控(kong)屏(ping)(ping)(ping)的(de)(de)特點：

■對大多數的環(huan)境污(wu)染(ran)物有抗力。

■人體成為線路的一部(bu)分，因而漂移(yi)現象比較嚴(yan)重。

■帶(dai)手套(tao)不(bu)起作用。

■需經常校準。

■不適用(yong)于(yu)金屬機柜。

■當外界(jie)有電感和(he)磁感的(de)時候，會(hui)使觸摸屏失靈。

上面說(shuo)的(de)那么多，其實很簡單，觸(chu)摸屏板(ban)有(you)(you)兩(liang)個導電(dian)層(ceng)(ceng)(ceng)，一(yi)層(ceng)(ceng)(ceng)有(you)(you)電(dian)壓，一(yi)層(ceng)(ceng)(ceng)沒有(you)(you)電(dian)壓，兩(liang)層(ceng)(ceng)(ceng)之間有(you)(you)小小的(de)空(kong)間使兩(liang)層(ceng)(ceng)(ceng)平(ping)時不接(jie)觸(chu)，按(an)下觸(chu)摸屏時兩(liang)層(ceng)(ceng)(ceng)的(de)某一(yi)點接(jie)觸(chu)上，沒有(you)(you)電(dian)壓一(yi)層(ceng)(ceng)(ceng)會有(you)(you)一(yi)個電(dian)壓，這個電(dian)壓通(tong)過另外兩(liang)線輸(shu)出，送給(gei)CPU處理，在與程序(xu)做對比，就知道使用(yong)者按(an)的(de)是哪(na)里了。

2、觸摸屏板的種類

觸(chu)摸屏(ping)板大家都(dou)知(zhi)道一般有四(si)種(zhong)，通常我們手機用的(de)都(dou)是(shi)電阻屏(ping)，用別(bie)的(de)屏(ping)的(de)基本(ben)(ben)沒有，那么我們經常看到(dao)的(de)手機用的(de)觸(chu)摸屏(ping)板，都(dou)是(shi)四(si)線引出的(de)，基本(ben)(ben)可以(yi)斷定都(dou)是(shi)電阻屏(ping)，因(yin)為電容屏(ping)的(de)缺點太多，比如帶(dai)手套就(jiu)沒辦(ban)法觸(chu)摸到(dao)或(huo)是(shi)位置不(bu)準，而且(qie)還要(yao)(yao)需要(yao)(yao)經常的(de)校準，所以(yi)很(hen)少用在手機上。

3、觸摸屏板的測量及分辯X軸和Y軸

觸(chu)摸(mo)屏(ping)板一(yi)般用看(kan)(kan)(kan)走(zou)線(xian)的(de)方法都能(neng)看(kan)(kan)(kan)的(de)出來，一(yi)般的(de)手(shou)機觸(chu)摸(mo)屏(ping)板，引線(xian)在屏(ping)下方，觸(chu)摸(mo)面向(xiang)上，屏(ping)內的(de)引線(xian)連(lian)到最左邊(bian)的(de)那條(tiao)(tiao)豎線(xian)，可以看(kan)(kan)(kan)做是Y軸，和屏(ping)下方那條(tiao)(tiao)相連(lian)的(de)連(lian)線(xian)，可以看(kan)(kan)(kan)做是X軸，和這(zhe)兩(liang)條(tiao)(tiao)線(xian)對(dui)應方向(xiang)的(de)那兩(liang)條(tiao)(tiao)分(fen)別(bie)是Y-和X-。（這(zhe)里提到的(de)是多數機器的(de)走(zou)線(xian)）。

首先要找(zhao)到(dao)觸(chu)摸板(ban)上的(de)(de)(de)(de)(de)(de)(de)對(dui)(dui)應(ying)的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)，也(ye)(ye)就是Y對(dui)(dui)Y-，X對(dui)(dui)X-，這(zhe)也(ye)(ye)不(bu)是必須的(de)(de)(de)(de)(de)(de)(de)，用(yong)(yong)(yong)(yong)萬用(yong)(yong)(yong)(yong)表測量，可以很快的(de)(de)(de)(de)(de)(de)(de)找(zhao)到(dao)這(zhe)兩組對(dui)(dui)應(ying)的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)，用(yong)(yong)(yong)(yong)兩個(ge)表筆(bi)先接任意接兩條(tiao)引出(chu)(chu)(chu)線(xian)(xian)，同時(shi)用(yong)(yong)(yong)(yong)手(shou)去觸(chu)摸屏(ping)的(de)(de)(de)(de)(de)(de)(de)觸(chu)摸面，如果(guo)萬用(yong)(yong)(yong)(yong)表的(de)(de)(de)(de)(de)(de)(de)阻值(zhi)不(bu)變，那可以斷定這(zhe)兩條(tiao)就是對(dui)(dui)應(ying)的(de)(de)(de)(de)(de)(de)(de)兩條(tiao)線(xian)(xian)，也(ye)(ye)就是YY-或XX-的(de)(de)(de)(de)(de)(de)(de)引出(chu)(chu)(chu)線(xian)(xian)，剩下的(de)(de)(de)(de)(de)(de)(de)兩條(tiao)線(xian)(xian)就是另外一組線(xian)(xian)，如果(guo)阻值(zhi)變化(hua)，那就不(bu)是對(dui)(dui)應(ying)的(de)(de)(de)(de)(de)(de)(de)線(xian)(xian)，這(zhe)時(shi)就應(ying)該(gai)在去測別的(de)(de)(de)(de)(de)(de)(de)引線(xian)(xian)，直(zhi)到(dao)測出(chu)(chu)(chu)來，記錄下觸(chu)摸屏(ping)板(ban)的(de)(de)(de)(de)(de)(de)(de)引出(chu)(chu)(chu)線(xian)(xian)的(de)(de)(de)(de)(de)(de)(de)對(dui)(dui)應(ying)一組線(xian)(xian)的(de)(de)(de)(de)(de)(de)(de)定義以做備用(yong)(yong)(yong)(yong)，（暫時(shi)不(bu)用(yong)(yong)(yong)(yong)分出(chu)(chu)(chu)YY-和(he)XX-）。
