Nrog rau kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, peb lub neej tau muaj xim ntau dua. Txawm li cas los xij, LCD Screen kuj muaj cov khoom lag luam zoo hauv 5G era thiab pab pawg tshaj lij. Lawv feem ntau siv rau TV, khoos phis tawj saib, laptops, ntsiav tshuaj, smartphones, koob yees duab digital, portable gaming devices, thiab car displays. Lawv kuj muaj nyob rau hauv cov khoom siv, khoom siv kho mob, thiab ntau yam khoom siv hluav taws xob. Lub vijtsam kov yog ib qho khoom siv uas tso cai rau cov neeg siv tuaj yeem kov lub vijtsam ncaj qha rau kev tawm tswv yim. Nws tso cai rau cov neeg siv los ua ntau yam lus txib thiab kev ua haujlwm los ntawm kev kov lub vijtsam ncaj qha nrog lawv cov ntiv tes lossis cov cwj mem tshwj xeeb thiab lwm yam khoom. Touchscreens feem ntau yog siv rau hauv cov khoom siv hluav taws xob thiab cov tshuab computer, muab cov kev paub zoo thiab kev sib tham zoo heev ntawm kev ua haujlwm, thiab tau siv dav hauv ntau yam khoom siv xws li smartphones, ntsiav tshuaj, cov ntaub ntawv kiosks, vending machines, industrial control equipment, etc.
Resistive Touch Screen:
Hom kev tshuaj ntsuam no siv ob txheej txheej ntawm cov yeeb yaj kiab rhiab heev. Thaum tus neeg siv kov lub vijtsam, ob lub yeeb yaj kiab tuaj rau hauv kev sib cuag thiab hloov qhov tam sim no, yog li txiav txim siab qhov chaw kov. Qhov kom zoo dua ntawm cov ntxaij vab tshaus tiv thaiv yog tias lawv pheej yig, tab sis lawv cov kev daws teeb meem thiab pob tshab yog qhov tsawg.
Nto capacitive touchscreen:
Lub ntsej muag capacitive kov npo pom qhov chaw kov raws li tus nqi ntawm tus neeg siv tus ntiv tes. Nws qhov zoo muaj xws li kev txhawb nqa rau ntau qhov kov, siab dua pob tshab, thiab kav ntev. Cov tshuab no feem ntau muab faib ua ob hom: inductive capacitive type thiab nto acoustic yoj hom.
Projected Capacitive Touch Screen: siv inductive inductance rau kov nrhiav, haum rau high-precision thiab ntau kov.
Surface Acoustic Wave Touch Screen: siv lub suab nthwv dej los nthuav tawm thiab xav txog ntawm cov iav qhov chaw kom pom cov haujlwm kov, haum rau cov ntawv thov uas xav tau kom pom tseeb thiab cov khoom siv kho qhov muag zoo heev.
Lwm hom:
Infrared Touch Screen: siv lub ntsuas hluav taws xob infrared txhawm rau txheeb xyuas txoj haujlwm ntawm tus neeg siv tus ntiv tes lossis khoom.
Khoov Sensor Kov Screen: Txoj haujlwm kov yog txiav txim siab los ntawm kev kuaj xyuas qhov deformation ntawm lub vijtsam los ntawm khoov sensor.
Active Digitizer Touchscreen: Ua ke nrog tus cwj mem digital kom paub meej cov tswv yim thiab kev sau ntawv.
Optical Imaging Touch Screen: Kev ntes tus neeg siv txoj haujlwm kov los ntawm cov khoom siv kho qhov muag.
Muaj ob peb hom kev kov cov ntxaij vab tshaus, suav nrog cov resistive (dual) deg capacitive thiab inductive capacitive, nto acoustic yoj, infrared thiab dabtsi yog khoov yoj, nrog rau cov kev hloov pauv digital thiab cov duab kho qhov muag. Nws tuaj yeem muab faib ua ob pawg. Ib qho tseem ceeb T9, xws li thawj peb lub vijtsam kov, thiab lwm qhov uas tsis tas yuav ITO, xws li tom kawg. Feem ntau siv cov tshuaj tiv thaiv kov cov ntxaij vab tshaus thiab capacitive kov cov ntxaij vab tshaus ntawm kev ua lag luam tam sim no siv cov ntaub ntawv ITO.
ITO sawv cev rau indium tin oxide. Nws yog pob tshab conductor. Los ntawm kev kho cov tin ratio, deposition txoj kev, oxidation degree, thiab grain loj, cov khoom ntawm t khoom yuav raug kho. Hom thib peb ntawm cov khoom siv ITO muaj cov pob tshab zoo tab sis kev ua haujlwm siab; ITO cov khoom muaj impedance tsawg tab sis tsis pom zoo. Thaum PET tso rau ntawm polyester zaj duab xis, cov tshuaj tiv thaiv kub poob qis dua 150 degrees, uas ua rau tsis tiav oxidation ntawm ITO. Tom qab daim ntawv thov, ITO yuav raug rau huab cua lossis huab cua hauv ib cheeb tsam, thiab nws cov impedance tom qab oxidation hloov raws sijhawm. Qhov no ua rau cov tshuaj tiv thaiv kov kom tau txais kev ntsuas tsis tu ncua.
