紅外觸摸屏的工作原理：

觸(chu)(chu)摸(mo)屏的(de)四周布滿紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)接(jie)收(shou)(shou)管(guan)和紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)發射(she)管(guan)，這些紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)管(guan)在觸(chu)(chu)摸(mo)屏表面呈一(yi)(yi)(yi)(yi)一(yi)(yi)(yi)(yi)對(dui)應(ying)的(de)排列關系，形成(cheng)一(yi)(yi)(yi)(yi)張由紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)線(xian)(xian)布成(cheng)的(de)光(guang)網(wang)，當(dang)有物(wu)體(手(shou)指、帶(dai)手(shou)套或(huo)任何觸(chu)(chu)摸(mo)物(wu)體)進(jin)入紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)光(guang)網(wang)阻擋住某處(chu)的(de)紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)線(xian)(xian)發射(she)接(jie)收(shou)(shou)時，此點橫(heng)豎兩個方向的(de)接(jie)收(shou)(shou)管(guan)收(shou)(shou)到(dao)的(de)紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)線(xian)(xian)的(de)強弱就會發生變化(hua)，設備通(tong)過了解紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)線(xian)(xian)的(de)接(jie)收(shou)(shou)情況的(de)變化(hua)就能知道何處(chu)進(jin)行(xing)(xing)了觸(chu)(chu)摸(mo)。紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)觸(chu)(chu)摸(mo)屏通(tong)過硬件設計(ji)和軟件編程，可以(yi)對(dui)各(ge)點數據(ju)進(jin)行(xing)(xing)插值計(ji)算，可以(yi)達到(dao)32768 X 32768的(de)分辨率。在紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)觸(chu)(chu)摸(mo)屏工(gong)作時的(de)同一(yi)(yi)(yi)(yi)瞬(shun)間，只(zhi)有一(yi)(yi)(yi)(yi)對(dui)紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)對(dui)管(guan) (指物(wu)理位置相對(dui)應(ying)的(de)一(yi)(yi)(yi)(yi)只(zhi)發射(she)管(guan)和一(yi)(yi)(yi)(yi)只(zhi)接(jie)收(shou)(shou)管(guan))在進(jin)行(xing)(xing)數據(ju)工(gong)作，電路通(tong)過對(dui)紅(hong)(hong)(hong)(hong)(hong)(hong)外(wai)(wai)(wai)對(dui)管(guan)高頻率的(de)數據(ju)采(cai)集來達到(dao)迅速反應(ying)的(de)效(xiao)果，因此觸(chu)(chu)摸(mo)屏的(de)反應(ying)速度(du)非常(chang)快.

紅外線觸摸屏使(shi)用原(yuan)理：

在(zai)顯(xian)示(shi)器上(shang)加上(shang)光(guang)點距(ju)架框（紅(hong)外(wai)(wai)觸(chu)(chu)(chu)(chu)摸(mo)框），無(wu)需(xu)在(zai)屏(ping)幕表面(mian)加上(shang)涂層(ceng)或(huo)接駁控制(zhi)器。光(guang)點距(ju)架框的(de)(de)四邊排列了(le)(le)紅(hong)外(wai)(wai)線(xian)發射管及接收管，在(zai)屏(ping)幕表面(mian)形成一個紅(hong)外(wai)(wai)線(xian)網。以手指觸(chu)(chu)(chu)(chu)摸(mo)屏(ping)幕某一點，便(bian)會(hui)擋(dang)住經過該位置的(de)(de)橫豎兩(liang)條(tiao)紅(hong)外(wai)(wai)線(xian)，計算機(ji)便(bian)可(ke)(ke)即時算出觸(chu)(chu)(chu)(chu)摸(mo)點位置。從而便(bian)可(ke)(ke)以代(dai)替(ti)了(le)(le)傳(chuan)統的(de)(de)鼠(shu)標(biao)和鍵(jian)(jian)盤(pan)這樣的(de)(de)外(wai)(wai)接設備，直接在(zai)顯(xian)示(shi)器上(shang)用手指或(huo)者(zhe)(zhe)不(bu)透(tou)明名物體在(zai)顯(xian)示(shi)器上(shang)觸(chu)(chu)(chu)(chu)摸(mo)點擊(ji)任何操(cao)作圖(tu)標(biao)，系統在(zai)接上(shang)觸(chu)(chu)(chu)(chu)摸(mo)設備時會(hui)自動出現觸(chu)(chu)(chu)(chu)摸(mo)軟鍵(jian)(jian)盤(pan)，同(tong)樣可(ke)(ke)以在(zai)顯(xian)示(shi)桌(zhuo)面(mian)上(shang)使(shi)用軟鍵(jian)(jian)盤(pan)操(cao)作，真正(zheng)意義(yi)上(shang)的(de)(de)達到了(le)(le)人機(ji)互(hu)動的(de)(de)感念(nian)。觸(chu)(chu)(chu)(chu)摸(mo)屏(ping)的(de)(de)出現也為不(bu)太習慣鼠(shu)標(biao)及鍵(jian)(jian)盤(pan)的(de)(de)使(shi)用者(zhe)(zhe)帶(dai)來了(le)(le)方便(bian)，可(ke)(ke)以直接在(zai)電(dian)腦桌(zhuo)面(mian)上(shang)手寫。隨著時代(dai)的(de)(de)發展，紅(hong)外(wai)(wai)觸(chu)(chu)(chu)(chu)摸(mo)屏(ping)可(ke)(ke)以實現多點操(cao)作及支(zhi)持多人操(cao)作，這是(shi)傳(chuan)統的(de)(de)鼠(shu)標(biao)不(bu)能(neng)達到的(de)(de)領域(yu)。
