紅(hong)外觸摸屏的工(gong)作(zuo)原(yuan)理：

觸(chu)(chu)(chu)(chu)摸(mo)(mo)屏的(de)(de)四周(zhou)布滿(man)紅(hong)(hong)(hong)外(wai)(wai)接收管和(he)紅(hong)(hong)(hong)外(wai)(wai)發(fa)(fa)射管，這些紅(hong)(hong)(hong)外(wai)(wai)管在(zai)觸(chu)(chu)(chu)(chu)摸(mo)(mo)屏表(biao)面呈一(yi)一(yi)對應(ying)的(de)(de)排列關系，形成(cheng)一(yi)張(zhang)由(you)紅(hong)(hong)(hong)外(wai)(wai)線(xian)(xian)布成(cheng)的(de)(de)光(guang)網，當有物(wu)體(ti)(手指、帶手套或任(ren)何觸(chu)(chu)(chu)(chu)摸(mo)(mo)物(wu)體(ti))進入紅(hong)(hong)(hong)外(wai)(wai)光(guang)網阻擋住某處(chu)的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)線(xian)(xian)發(fa)(fa)射接收時，此點橫豎兩個方(fang)向的(de)(de)接收管收到(dao)的(de)(de)紅(hong)(hong)(hong)外(wai)(wai)線(xian)(xian)的(de)(de)強(qiang)弱就會發(fa)(fa)生(sheng)變化，設(she)(she)備通(tong)過了(le)解紅(hong)(hong)(hong)外(wai)(wai)線(xian)(xian)的(de)(de)接收情況的(de)(de)變化就能知道何處(chu)進行(xing)了(le)觸(chu)(chu)(chu)(chu)摸(mo)(mo)。紅(hong)(hong)(hong)外(wai)(wai)觸(chu)(chu)(chu)(chu)摸(mo)(mo)屏通(tong)過硬(ying)件設(she)(she)計(ji)(ji)和(he)軟件編程，可(ke)(ke)以對各點數據進行(xing)插值計(ji)(ji)算(suan)，可(ke)(ke)以達到(dao)32768 X 32768的(de)(de)分辨率。在(zai)紅(hong)(hong)(hong)外(wai)(wai)觸(chu)(chu)(chu)(chu)摸(mo)(mo)屏工(gong)作時的(de)(de)同一(yi)瞬間，只(zhi)有一(yi)對紅(hong)(hong)(hong)外(wai)(wai)對管 (指物(wu)理位(wei)置相對應(ying)的(de)(de)一(yi)只(zhi)發(fa)(fa)射管和(he)一(yi)只(zhi)接收管)在(zai)進行(xing)數據工(gong)作，電路通(tong)過對紅(hong)(hong)(hong)外(wai)(wai)對管高頻率的(de)(de)數據采集來達到(dao)迅(xun)速反應(ying)的(de)(de)效果，因(yin)此觸(chu)(chu)(chu)(chu)摸(mo)(mo)屏的(de)(de)反應(ying)速度非(fei)常快(kuai).

紅外線(xian)觸摸屏(ping)使用原理(li)：

在(zai)顯示器(qi)上(shang)(shang)(shang)(shang)加上(shang)(shang)(shang)(shang)光點距(ju)架框（紅(hong)外觸(chu)摸(mo)框），無(wu)需在(zai)屏(ping)(ping)幕表面加上(shang)(shang)(shang)(shang)涂層或接(jie)(jie)駁控制器(qi)。光點距(ju)架框的(de)(de)四邊排列了紅(hong)外線(xian)(xian)發射管及接(jie)(jie)收(shou)管，在(zai)屏(ping)(ping)幕表面形成一(yi)個(ge)紅(hong)外線(xian)(xian)網。以手指(zhi)觸(chu)摸(mo)屏(ping)(ping)幕某一(yi)點，便(bian)會擋住經(jing)過該位置的(de)(de)橫豎兩條紅(hong)外線(xian)(xian)，計算(suan)機便(bian)可即時(shi)算(suan)出(chu)觸(chu)摸(mo)點位置。從而便(bian)可以代替了傳統(tong)的(de)(de)鼠(shu)標(biao)和鍵盤這樣的(de)(de)外接(jie)(jie)設(she)備，直(zhi)接(jie)(jie)在(zai)顯示器(qi)上(shang)(shang)(shang)(shang)用(yong)(yong)(yong)手指(zhi)或者不(bu)透明名物體在(zai)顯示器(qi)上(shang)(shang)(shang)(shang)觸(chu)摸(mo)點擊任何操作圖標(biao)，系(xi)統(tong)在(zai)接(jie)(jie)上(shang)(shang)(shang)(shang)觸(chu)摸(mo)設(she)備時(shi)會自動出(chu)現(xian)觸(chu)摸(mo)軟鍵盤，同樣可以在(zai)顯示桌(zhuo)(zhuo)面上(shang)(shang)(shang)(shang)使(shi)用(yong)(yong)(yong)軟鍵盤操作，真(zhen)正(zheng)意義上(shang)(shang)(shang)(shang)的(de)(de)達到(dao)了人(ren)(ren)機互動的(de)(de)感念。觸(chu)摸(mo)屏(ping)(ping)的(de)(de)出(chu)現(xian)也為不(bu)太習慣鼠(shu)標(biao)及鍵盤的(de)(de)使(shi)用(yong)(yong)(yong)者帶來了方便(bian)，可以直(zhi)接(jie)(jie)在(zai)電腦桌(zhuo)(zhuo)面上(shang)(shang)(shang)(shang)手寫。隨著時(shi)代的(de)(de)發展(zhan)，紅(hong)外觸(chu)摸(mo)屏(ping)(ping)可以實現(xian)多點操作及支(zhi)持多人(ren)(ren)操作，這是傳統(tong)的(de)(de)鼠(shu)標(biao)不(bu)能達到(dao)的(de)(de)領域。
