Lub infrared kov tshuaj ntsuam siv los ntawm kov tag nrho-hauv-ib lub tshuab siv lub infrared matrix densely faib rau hauv X thiab y cov lus qhia los kuaj xyuas thiab nrhiav tus neeg siv kov. Lub infrared kov screen yog nruab nrog lub rooj tsav xwm Circuit Court ncej nyob rau hauv pem hauv ntej ntawm cov zaub. Lub rooj tsav xwm hauv Circuit Court yog teem nrog infrared transmitting hlab thiab infrared txais cov raj ntawm plaub sab ntawm lub vijtsam, ib qho los ntawm ib qho sib txuas rau kab rov tav thiab ntsug cross infrared matrix. Thaum tus neeg siv kov lub vijtsam, nws tus ntiv tes yuav thaiv ob kab kab rov tav thiab ntsug infrared hluav taws xob dawb board kab hla txoj haujlwm, yog li nws tuaj yeem txiav txim siab txoj haujlwm ntawm qhov kov ntawm lub vijtsam. Infrared touch screen yog ib qho khoom siv hluav taws xob sib xyaw ua ke zoo heev. Lub infrared kov screen muaj ib tug ua tiav integrated tswj Circuit Court, ib pab pawg neeg ntawm high-precision thiab anti-interference infrared transmitting hlab thiab ib pab pawg neeg ntawm infrared txais hlab, uas yog ntoo khaub lig mounted nyob rau hauv heev integrated Circuit Court board nyob rau hauv ob opposite lus qhia los tsim ib tug tsis pom kev. infrared grating. Cov kev tswj xyuas ntse uas tau muab tso rau hauv lub voj voog tswj tsis tu ncua xa cov pulses mus rau diode los ua ib qho infrared deflection beam grid. Thaum kov cov khoom xws li cov ntiv tes nkag mus rau hauv lub grating, lub teeb ci ntsa iab raug thaiv. Qhov kev tswj xyuas ntse yuav kuaj xyuas qhov kev hloov pauv ntawm lub teeb poob thiab xa cov teeb liab mus rau qhov kev tswj xyuas kom paub meej txog qhov x-axis thiab y-axis kev tswj hwm qhov tseem ceeb.
