觸(chu)摸(mo)屏板的工作原理 觸(chu)摸(mo)屏板的種類
1、觸摸屏板的工作原理
從(cong)技(ji)術(shu)原理(li)(li)(li)來區別(bie)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping),可分(fen)為五個基本種(zhong)類:矢量壓(ya)(ya)力傳感技(ji)術(shu)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)、電阻技(ji)術(shu)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)、電容技(ji)術(shu)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)、紅外線技(ji)術(shu)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)、表(biao)面聲波(bo)技(ji)術(shu)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)。其(qi)中矢量壓(ya)(ya)力傳感技(ji)術(shu)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)已退出歷(li)史舞臺。觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)紅外屏(ping)(ping)(ping)價格低廉,但(dan)其(qi)外框易碎,容易產生光(guang)干擾,曲面情況下失真(zhen);電容屏(ping)(ping)(ping)設計理(li)(li)(li)論好(hao),但(dan)其(qi)圖象失真(zhen)問題很難得(de)到根本解決;電阻屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)定位準確,但(dan)其(qi)價格頗高,且怕刮易損。表(biao)面聲波(bo)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)解決了以(yi)往(wang)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)各種(zhong)缺陷(xian),清(qing)晰抗暴,適于各種(zhong)場合,缺憾是屏(ping)(ping)(ping)表(biao)面的(de)(de)(de)(de)(de)水(shui)滴、塵土(tu)會(hui)使(shi)觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)變的(de)(de)(de)(de)(de)遲鈍,甚至不工(gong)作(zuo)。按照觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)的(de)(de)(de)(de)(de)工(gong)作(zuo)原理(li)(li)(li)和(he)傳輸(shu)信息的(de)(de)(de)(de)(de)介質,我們(men)把觸(chu)(chu)(chu)摸(mo)屏(ping)(ping)(ping)分(fen)為四種(zhong),它(ta)們(men)分(fen)別(bie)為電阻式、紅外線式、電容感應式以(yi)及表(biao)面聲波(bo)式。
(1)電阻觸摸屏
電(dian)(dian)阻(zu)觸摸屏的(de)屏體部分(fen)(fen)是(shi)一(yi)(yi)(yi)塊與顯示器表面相(xiang)匹配的(de)多層(ceng)(ceng)復(fu)合薄(bo)膜,由一(yi)(yi)(yi)層(ceng)(ceng)玻(bo)璃或(huo)有機(ji)玻(bo)璃作為(wei)基層(ceng)(ceng),表面涂有一(yi)(yi)(yi)層(ceng)(ceng)透(tou)(tou)明(ming)(ming)的(de)導電(dian)(dian)層(ceng)(ceng),上面再蓋有一(yi)(yi)(yi)層(ceng)(ceng)外表面硬(ying)化處理、光滑防刮的(de)塑(su)料層(ceng)(ceng),它(ta)的(de)內表面也(ye)涂有一(yi)(yi)(yi)層(ceng)(ceng)透(tou)(tou)明(ming)(ming)導電(dian)(dian)層(ceng)(ceng),在兩層(ceng)(ceng)導電(dian)(dian)層(ceng)(ceng)之(zhi)間有許多細小(小于千分(fen)(fen)之(zhi)一(yi)(yi)(yi)英寸(cun))的(de)透(tou)(tou)明(ming)(ming)隔離(li)點把它(ta)們隔開絕緣。
當(dang)手指觸(chu)摸屏幕時,平常相互(hu)絕(jue)緣(yuan)的(de)(de)(de)(de)(de)兩層(ceng)(ceng)(ceng)導電(dian)(dian)(dian)層(ceng)(ceng)(ceng)就在(zai)觸(chu)摸點位(wei)置有了一(yi)個接(jie)(jie)觸(chu),因其中一(yi)面導電(dian)(dian)(dian)層(ceng)(ceng)(ceng)接(jie)(jie)通Y軸(zhou)(zhou)方(fang)向(xiang)的(de)(de)(de)(de)(de)均勻電(dian)(dian)(dian)壓(ya)(ya)場,使得(de)(de)(de)偵測層(ceng)(ceng)(ceng)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)由(you)零變為(wei)非(fei)零,這種接(jie)(jie)通狀態(tai)被控制器偵測到(dao)后,進行A/D轉換,并將得(de)(de)(de)到(dao)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)值與(yu)基準相比(bi)即可得(de)(de)(de)到(dao)觸(chu)摸點的(de)(de)(de)(de)(de)Y軸(zhou)(zhou)坐標,同理得(de)(de)(de)出X軸(zhou)(zhou)的(de)(de)(de)(de)(de)坐標,這就是(shi)所有電(dian)(dian)(dian)阻(zu)技(ji)術觸(chu)摸屏共同的(de)(de)(de)(de)(de)最基本原理。電(dian)(dian)(dian)阻(zu)類觸(chu)摸屏的(de)(de)(de)(de)(de)關鍵(jian)在(zai)于材料科技(ji)。電(dian)(dian)(dian)阻(zu)屏根據引出線數多(duo)(duo)少,分(fen)為(wei)四線、五線、六線等多(duo)(duo)線電(dian)(dian)(dian)阻(zu)觸(chu)摸屏。電(dian)(dian)(dian)阻(zu)式觸(chu)摸屏在(zai)強化玻璃表面分(fen)別涂上兩層(ceng)(ceng)(ceng)OTI透明(ming)氧化金屬(shu)導電(dian)(dian)(dian)層(ceng)(ceng)(ceng),最外面的(de)(de)(de)(de)(de)一(yi)層(ceng)(ceng)(ceng)OTI涂層(ceng)(ceng)(ceng)作為(wei)導電(dian)(dian)(dian)體,第二層(ceng)(ceng)(ceng)OTI則(ze)經過精密(mi)的(de)(de)(de)(de)(de)網絡附上橫豎(shu)兩個方(fang)向(xiang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)(ya)場,兩層(ceng)(ceng)(ceng)OTI之間以細(xi)小的(de)(de)(de)(de)(de)透明(ming)隔離點隔開(kai)。當(dang)手指接(jie)(jie)觸(chu)屏幕時,兩層(ceng)(ceng)(ceng)OTI導電(dian)(dian)(dian)層(ceng)(ceng)(ceng)就會(hui)出現一(yi)個接(jie)(jie)觸(chu)點,電(dian)(dian)(dian)腦同時檢測電(dian)(dian)(dian)壓(ya)(ya)及(ji)電(dian)(dian)(dian)流(liu),計(ji)算(suan)出觸(chu)摸的(de)(de)(de)(de)(de)位(wei)置,反(fan)應速度為(wei)10-20ms。
五線(xian)電(dian)(dian)阻觸(chu)摸屏的(de)外層(ceng)導電(dian)(dian)層(ceng)使(shi)用(yong)的(de)是(shi)延(yan)展性好(hao)的(de)鎳金(jin)(jin)涂層(ceng)材(cai)料,外導電(dian)(dian)層(ceng)由于頻繁觸(chu)摸,使(shi)用(yong)延(yan)展性好(hao)的(de)鎳金(jin)(jin)材(cai)料目的(de)是(shi)為(wei)了延(yan)長使(shi)用(yong)壽命(ming),但是(shi)工(gong)藝成本較(jiao)為(wei)高(gao)昂(ang)。鎳金(jin)(jin)導電(dian)(dian)層(ceng)雖然(ran)延(yan)展性好(hao),但是(shi)只能作透明導體,不適合(he)作為(wei)電(dian)(dian)阻觸(chu)控(kong)屏的(de)工(gong)作面(mian),因為(wei)它導電(dian)(dian)率高(gao),而且金(jin)(jin)屬(shu)不易做到(dao)厚度非常均勻,不宜(yi)作電(dian)(dian)壓(ya)分布層(ceng),只能作為(wei)探層(ceng)。
電阻(zu)(zu)觸(chu)摸(mo)屏是一種(zhong)對(dui)外(wai)界完(wan)全隔離的(de)工(gong)作環境,不怕灰塵和水汽,它可以(yi)用任(ren)何物(wu)體來觸(chu)摸(mo),可以(yi)用來寫字畫(hua)(hua)畫(hua)(hua),比較(jiao)適合工(gong)業控(kong)制領域及辦公室(shi)內(nei)有(you)限人的(de)使用。電阻(zu)(zu)觸(chu)摸(mo)屏共(gong)同的(de)缺(que)點是因為復合薄膜的(de)外(wai)層(ceng)采用塑膠材料,不知道的(de)人太(tai)用力或使用銳器觸(chu)摸(mo)可能劃傷(shang)整個觸(chu)控(kong)屏而導致報廢(fei)。不過,在限度(du)之內(nei),劃傷(shang)只會傷(shang)及外(wai)導電層(ceng),外(wai)導電層(ceng)的(de)劃傷(shang)對(dui)于五線(xian)電阻(zu)(zu)觸(chu)摸(mo)屏來說沒有(you)關系,而對(dui)四(si)線(xian)電阻(zu)(zu)觸(chu)摸(mo)屏來說是致命的(de)。
(2)電容技術觸摸屏:
是(shi)(shi)(shi)利用(yong)人體的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)感應進行工(gong)作(zuo)(zuo)的(de)(de)(de)。電(dian)(dian)(dian)(dian)容式(shi)觸(chu)摸屏是(shi)(shi)(shi)是(shi)(shi)(shi)一(yi)塊四(si)(si)(si)層(ceng)(ceng)(ceng)(ceng)復合玻(bo)璃(li)(li)屏,玻(bo)璃(li)(li)屏的(de)(de)(de)內表面和(he)夾層(ceng)(ceng)(ceng)(ceng)各涂有一(yi)層(ceng)(ceng)(ceng)(ceng)ITO,最外層(ceng)(ceng)(ceng)(ceng)是(shi)(shi)(shi)一(yi)薄(bo)層(ceng)(ceng)(ceng)(ceng)矽土玻(bo)璃(li)(li)保護層(ceng)(ceng)(ceng)(ceng),夾層(ceng)(ceng)(ceng)(ceng)ITO涂層(ceng)(ceng)(ceng)(ceng)作(zuo)(zuo)為工(gong)作(zuo)(zuo)面,四(si)(si)(si)個(ge)角(jiao)上引(yin)出(chu)四(si)(si)(si)個(ge)電(dian)(dian)(dian)(dian)極,內層(ceng)(ceng)(ceng)(ceng)ITO為屏蔽層(ceng)(ceng)(ceng)(ceng)以保證良好的(de)(de)(de)工(gong)作(zuo)(zuo)環境。當手(shou)(shou)指(zhi)(zhi)觸(chu)摸在(zai)金屬(shu)層(ceng)(ceng)(ceng)(ceng)上時,由于(yu)人體電(dian)(dian)(dian)(dian)場(chang),用(yong)戶(hu)和(he)觸(chu)控屏表面形成以一(yi)個(ge)耦合電(dian)(dian)(dian)(dian)容,對于(yu)高頻電(dian)(dian)(dian)(dian)流(liu)(liu)來說,電(dian)(dian)(dian)(dian)容是(shi)(shi)(shi)直(zhi)接導體,于(yu)是(shi)(shi)(shi)手(shou)(shou)指(zhi)(zhi)從(cong)(cong)接觸(chu)點吸(xi)走一(yi)個(ge)很(hen)小的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)。這個(ge)電(dian)(dian)(dian)(dian)流(liu)(liu)分從(cong)(cong)觸(chu)控屏的(de)(de)(de)四(si)(si)(si)角(jiao)上的(de)(de)(de)電(dian)(dian)(dian)(dian)極中流(liu)(liu)出(chu),并且流(liu)(liu)經(jing)這四(si)(si)(si)個(ge)電(dian)(dian)(dian)(dian)極的(de)(de)(de)電(dian)(dian)(dian)(dian)流(liu)(liu)與手(shou)(shou)指(zhi)(zhi)到四(si)(si)(si)角(jiao)的(de)(de)(de)距離成正比,控制(zhi)器通(tong)過對這四(si)(si)(si)個(ge)電(dian)(dian)(dian)(dian)流(liu)(liu)比例的(de)(de)(de)精確計(ji)算,得出(chu)觸(chu)摸點的(de)(de)(de)位置(zhi)。電(dian)(dian)(dian)(dian)容觸(chu)控屏的(de)(de)(de)特(te)點:
■對大多(duo)數的環境污染物(wu)有抗力。
■人(ren)體成為(wei)線路(lu)的一(yi)部分,因而(er)漂移現(xian)象比較嚴重。
■帶手套不起作用。
■需經常校準。
■不適用于(yu)金屬機柜。
■當(dang)外界有電(dian)感和磁感的(de)時候,會使觸(chu)摸屏失靈。
上(shang)面說的那么(me)多,其實很簡單,觸摸屏板(ban)有兩(liang)個導電(dian)層(ceng)(ceng),一(yi)層(ceng)(ceng)有電(dian)壓,一(yi)層(ceng)(ceng)沒(mei)有電(dian)壓,兩(liang)層(ceng)(ceng)之(zhi)間有小小的空間使兩(liang)層(ceng)(ceng)平時(shi)不接觸,按下(xia)觸摸屏時(shi)兩(liang)層(ceng)(ceng)的某一(yi)點(dian)接觸上(shang),沒(mei)有電(dian)壓一(yi)層(ceng)(ceng)會有一(yi)個電(dian)壓,這(zhe)個電(dian)壓通過另外兩(liang)線輸出,送(song)給CPU處理,在(zai)與程序做對比,就(jiu)知道使用者按的是哪(na)里(li)了。
2、觸摸屏板的種類
觸摸屏(ping)板大家都知道一般有(you)四種,通(tong)常(chang)我們手機用(yong)(yong)的都是(shi)電(dian)阻屏(ping),用(yong)(yong)別的屏(ping)的基(ji)本沒(mei)有(you),那么我們經常(chang)看(kan)到的手機用(yong)(yong)的觸摸屏(ping)板,都是(shi)四線引出的,基(ji)本可以斷定都是(shi)電(dian)阻屏(ping),因為電(dian)容屏(ping)的缺點太(tai)多,比如帶手套就(jiu)沒(mei)辦(ban)法觸摸到或是(shi)位(wei)置不準(zhun),而且還要需要經常(chang)的校準(zhun),所以很(hen)少用(yong)(yong)在手機上。
3、觸摸屏板的測量及分辯X軸和Y軸
觸(chu)摸(mo)屏板一般(ban)用(yong)看走線的(de)(de)方(fang)法(fa)都能看的(de)(de)出來,一般(ban)的(de)(de)手機(ji)觸(chu)摸(mo)屏板,引線在屏下方(fang),觸(chu)摸(mo)面向上,屏內的(de)(de)引線連(lian)到最左(zuo)邊的(de)(de)那條(tiao)豎線,可以看做是(shi)Y軸,和(he)屏下方(fang)那條(tiao)相連(lian)的(de)(de)連(lian)線,可以看做是(shi)X軸,和(he)這(zhe)兩條(tiao)線對(dui)應方(fang)向的(de)(de)那兩條(tiao)分(fen)別是(shi)Y-和(he)X-。(這(zhe)里提到的(de)(de)是(shi)多數機(ji)器的(de)(de)走線)。
首先要找到(dao)觸(chu)摸(mo)板上的(de)(de)對(dui)(dui)應(ying)(ying)的(de)(de)線(xian)(xian),也就(jiu)(jiu)(jiu)是Y對(dui)(dui)Y-,X對(dui)(dui)X-,這(zhe)也不是必須的(de)(de),用(yong)(yong)萬(wan)用(yong)(yong)表測量,可以很快的(de)(de)找到(dao)這(zhe)兩(liang)(liang)(liang)(liang)組對(dui)(dui)應(ying)(ying)的(de)(de)線(xian)(xian),用(yong)(yong)兩(liang)(liang)(liang)(liang)個表筆先接任意接兩(liang)(liang)(liang)(liang)條引(yin)出(chu)(chu)線(xian)(xian),同時(shi)(shi)用(yong)(yong)手(shou)去觸(chu)摸(mo)屏的(de)(de)觸(chu)摸(mo)面,如果萬(wan)用(yong)(yong)表的(de)(de)阻值(zhi)不變,那可以斷定這(zhe)兩(liang)(liang)(liang)(liang)條就(jiu)(jiu)(jiu)是對(dui)(dui)應(ying)(ying)的(de)(de)兩(liang)(liang)(liang)(liang)條線(xian)(xian),也就(jiu)(jiu)(jiu)是YY-或XX-的(de)(de)引(yin)出(chu)(chu)線(xian)(xian),剩(sheng)下的(de)(de)兩(liang)(liang)(liang)(liang)條線(xian)(xian)就(jiu)(jiu)(jiu)是另外一(yi)組線(xian)(xian),如果阻值(zhi)變化,那就(jiu)(jiu)(jiu)不是對(dui)(dui)應(ying)(ying)的(de)(de)線(xian)(xian),這(zhe)時(shi)(shi)就(jiu)(jiu)(jiu)應(ying)(ying)該(gai)在去測別的(de)(de)引(yin)線(xian)(xian),直(zhi)到(dao)測出(chu)(chu)來(lai),記錄(lu)下觸(chu)摸(mo)屏板的(de)(de)引(yin)出(chu)(chu)線(xian)(xian)的(de)(de)對(dui)(dui)應(ying)(ying)一(yi)組線(xian)(xian)的(de)(de)定義以做(zuo)備用(yong)(yong),(暫(zan)時(shi)(shi)不用(yong)(yong)分出(chu)(chu)YY-和XX-)。
4、觸摸屏的代換
看(kan)(kan)出(chu)(chu)走(zou)(zou)(zou)線(xian)(xian)和(he)測(ce)(ce)出(chu)(chu)X軸(zhou)(zhou)(zhou)和(he)Y軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)大致位(wei)置以后我(wo)們就(jiu)可以換屏(ping)(ping)板(ban)(ban)(ban)了(le),代換最(zui)(zui)基本的(de)(de)(de)(de)(de)(de)原則就(jiu)是(shi)(shi)(shi)(shi)大小一(yi)(yi)(yi)致,走(zou)(zou)(zou)線(xian)(xian)盡量一(yi)(yi)(yi)致,也(ye)就(jiu)是(shi)(shi)(shi)(shi)X軸(zhou)(zhou)(zhou)和(he)Y軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)位(wei)置與原屏(ping)(ping)板(ban)(ban)(ban)一(yi)(yi)(yi)樣的(de)(de)(de)(de)(de)(de)是(shi)(shi)(shi)(shi)最(zui)(zui)好的(de)(de)(de)(de)(de)(de),但(dan)多數時(shi)候(hou)我(wo)們遇不(bu)(bu)到(dao)(dao)那(nei)(nei)(nei)么合適的(de)(de)(de)(de)(de)(de)屏(ping)(ping)板(ban)(ban)(ban),這(zhe)時(shi)候(hou)就(jiu)要想辦法代換了(le),先(xian)(xian)看(kan)(kan)壞掉的(de)(de)(de)(de)(de)(de)那(nei)(nei)(nei)個屏(ping)(ping)板(ban)(ban)(ban),能看(kan)(kan)出(chu)(chu)線(xian)(xian)的(de)(de)(de)(de)(de)(de)走(zou)(zou)(zou)向的(de)(de)(de)(de)(de)(de)就(jiu)按(an)線(xian)(xian)的(de)(de)(de)(de)(de)(de)走(zou)(zou)(zou)向去(qu)接(jie),看(kan)(kan)不(bu)(bu)出(chu)(chu)的(de)(de)(de)(de)(de)(de)就(jiu)要測(ce)(ce)了(le),用(yong)(yong)萬(wan)用(yong)(yong)表測(ce)(ce)主板(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)觸(chu)摸(mo)屏(ping)(ping)的(de)(de)(de)(de)(de)(de)那(nei)(nei)(nei)四(si)條(tiao)線(xian)(xian),這(zhe)四(si)條(tiao)線(xian)(xian)中(zhong),有(you)(you)(you)兩條(tiao)是(shi)(shi)(shi)(shi)有(you)(you)(you)電(dian)壓(ya)的(de)(de)(de)(de)(de)(de),兩條(tiao)沒(mei)有(you)(you)(you),這(zhe)兩條(tiao)有(you)(you)(you)電(dian)壓(ya)的(de)(de)(de)(de)(de)(de),一(yi)(yi)(yi)般就(jiu)是(shi)(shi)(shi)(shi)Y和(he)Y-。好,我(wo)們來(lai)看(kan)(kan)怎(zen)么代換,先(xian)(xian)用(yong)(yong)測(ce)(ce)出(chu)(chu)的(de)(de)(de)(de)(de)(de)觸(chu)摸(mo)屏(ping)(ping)板(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)兩條(tiao)Y軸(zhou)(zhou)(zhou)線(xian)(xian),接(jie)到(dao)(dao)主板(ban)(ban)(ban)有(you)(you)(you)電(dian)壓(ya)的(de)(de)(de)(de)(de)(de)那(nei)(nei)(nei)兩端(duan),最(zui)(zui)好是(shi)(shi)(shi)(shi)能看(kan)(kan)出(chu)(chu)原機(ji)觸(chu)摸(mo)屏(ping)(ping)板(ban)(ban)(ban)的(de)(de)(de)(de)(de)(de)左(zuo)右(you)走(zou)(zou)(zou)線(xian)(xian)(YY-),這(zhe)樣可以很快的(de)(de)(de)(de)(de)(de)接(jie)好另外兩條(tiao),原機(ji)屏(ping)(ping)板(ban)(ban)(ban)看(kan)(kan)不(bu)(bu)出(chu)(chu)或是(shi)(shi)(shi)(shi)沒(mei)有(you)(you)(you)了(le),也(ye)可以先(xian)(xian)不(bu)(bu)用(yong)(yong)管(guan),接(jie)上(shang)(shang)就(jiu)行。在接(jie)上(shang)(shang)另兩條(tiao)線(xian)(xian),也(ye)就(jiu)是(shi)(shi)(shi)(shi)XX-,這(zhe)兩條(tiao)暫時(shi)不(bu)(bu)用(yong)(yong)分,主板(ban)(ban)(ban)加電(dian),試下看(kan)(kan)觸(chu)摸(mo)屏(ping)(ping)上(shang)(shang)有(you)(you)(you)沒(mei)有(you)(you)(you)什么反(fan)(fan)應(ying)(ying),如(ru)果都好用(yong)(yong)了(le),那(nei)(nei)(nei)恭(gong)喜你(ni)(ni),可以處理好裝機(ji)了(le),校準后可以正常用(yong)(yong)了(le),如(ru)果出(chu)(chu)現按(an)鍵錯亂(luan),比如(ru)說按(an)上(shang)(shang)面(mian)下面(mian)有(you)(you)(you)反(fan)(fan)應(ying)(ying),那(nei)(nei)(nei)就(jiu)是(shi)(shi)(shi)(shi)X軸(zhou)(zhou)(zhou)那(nei)(nei)(nei)兩條(tiao)接(jie)反(fan)(fan)了(le),也(ye)就(jiu)是(shi)(shi)(shi)(shi)上(shang)(shang)下那(nei)(nei)(nei)兩條(tiao)線(xian)(xian)反(fan)(fan)了(le),按(an)左(zuo)出(chu)(chu)右(you)那(nei)(nei)(nei)是(shi)(shi)(shi)(shi)Y軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)反(fan)(fan)了(le),換過來(lai)一(yi)(yi)(yi)般就(jiu)會好,要是(shi)(shi)(shi)(shi)出(chu)(chu)按(an)左(zuo)下,右(you)上(shang)(shang)的(de)(de)(de)(de)(de)(de)卻出(chu)(chu)來(lai)了(le),那(nei)(nei)(nei)不(bu)(bu)用(yong)(yong)我(wo)說,你(ni)(ni)也(ye)應(ying)(ying)該知道(dao)四(si)條(tiao)都反(fan)(fan)了(le),要Y軸(zhou)(zhou)(zhou)和(he)X軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)對應(ying)(ying)換過來(lai),這(zhe)些都是(shi)(shi)(shi)(shi)觸(chu)摸(mo)屏(ping)(ping)有(you)(you)(you)反(fan)(fan)應(ying)(ying)的(de)(de)(de)(de)(de)(de),要是(shi)(shi)(shi)(shi)沒(mei)有(you)(you)(you)任何反(fan)(fan)應(ying)(ying),那(nei)(nei)(nei)一(yi)(yi)(yi)定(ding)是(shi)(shi)(shi)(shi)你(ni)(ni)的(de)(de)(de)(de)(de)(de)Y軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)兩條(tiao)線(xian)(xian)接(jie)錯了(le),可能接(jie)到(dao)(dao)X軸(zhou)(zhou)(zhou)的(de)(de)(de)(de)(de)(de)引線(xian)(xian)上(shang)(shang)去(qu)了(le)或者(zhe)接(jie)錯了(le)一(yi)(yi)(yi)根線(xian)(xian),那(nei)(nei)(nei)這(zhe)時(shi)候(hou)機(ji)器的(de)(de)(de)(de)(de)(de)觸(chu)摸(mo)屏(ping)(ping)就(jiu)一(yi)(yi)(yi)點反(fan)(fan)應(ying)(ying)也(ye)沒(mei)有(you)(you)(you),這(zhe)就(jiu)是(shi)(shi)(shi)(shi)最(zui)(zui)基本的(de)(de)(de)(de)(de)(de)方法。
