Dab tsi kov qhov tseeb tiag txhais tau tias
Kov Accuracy vs Touch Sensitivity - Tsis yog Ib Yam
Kov qhov tseeb yog qhov ze ze npaum li cas qhov kev tshaj tawm kov sib koom ua ke nrog qhov tseeb ntawm lub cev tiv tauj. rhiab heev yog hais txog qhov yuav tsum tau muaj zog me me los yog qhov sib thooj los sau npe rau qhov kov. Kev daws teeb meem cuam tshuam rau qhov tsawg tshaj plaws uas pom tau txav mus los.
Ib qho yuam kev feem ntau yog qhov tsis meej pem siab nrog qhov raug siab. Ib qho screen rhiab heev tseem tuaj yeem raug kev txom nyem los ntawm cov kab tsis zoo thiab qhov ua yuam kev siab, tshwj xeeb tshaj yog nyob ze ntawm ntug lossis nyob rau hauv ib puag ncig kev ntxhov siab.
Kov qhov raug ntsuas li cas thiab cov lej txhais li cas
Cov kev ntsuas tseem ceeb suav nrog kev ua yuam kev linearity (kev sib npaug ntawm qhov chaw), kev rov ua dua (kev sib raug zoo thaum kov tib lub ntsiab lus), thiab ntug sib txawv. Cov no feem ntau raug soj ntsuam siv cov txheej txheem hais hauv IEC 62977 thiab cov qauv zoo sib xws.
Kev lag luam- qib kov qhov tseeb muaj cov kev daws teeb meem feem ntau lub hom phiaj ± 1mm lossis zoo dua nyob rau hauv thaj chaw nquag, thaum ntau cov neeg siv khoom vaj huam sib luag nyob ntawm ± 2-3mm. Nco ntsoov thov cov ncauj lus kom ntxaws linearity es tsis lees txais cov lus tsis meej "high precision" kev lag luam.
Lub 7-nti Waterproof Touch Screen LCD
Waterproof designs qhia txog kev cov nyom. Cov khaubncaws sab nraud povtseg ntxiv thiab cov iav npog tuab tuaj yeem ua rau parallax (visual offset) thiab me ntsis attenuate touch signals. Cov yeeb yaj kiab dej ntawm qhov chaw ua rau muaj kev nyuaj siab ntxiv rau capacitive sensing.
Kev ntsuas IP siab dua (IP65–IP68) feem ntau xav tau kev lag luam engineering- tawm. Hauv cov chaw ua zaub mov, ib puag ncig marine, thiab sab nraum zoov kiosks, a7-nti Waterproof Touch Screen LCDyuav tsum tswj kom ntseeg tau qhov tseeb txawm tias muaj dej noo, hnab looj tes, thiab kub hloov pauv. Yog tias koj daim ntawv thov cuam tshuam nrog dej tsis tu ncua, ntsuas qhov ntsuas qhov tseeb ntawm cov txheej txheem thaum ntxov.
Kev daws raws li kev muaj tiag
Lub 7 Nti 1024x600 LCD Screen muab kwv yees li 0.111mm ib pixel, xa cov lus pom zoo rau kev lag luam HMIs. Txawm li cas los xij, cov zaub siab daws teeb meem tsis tau txhais mus rau qhov sib piv kov precision. Kev tsis sib haum xeeb ua rau pom kev ua haujlwm tsis zoo - cov neeg siv coj mus rhaub ib lub caij tab sis qhib lwm qhov.

Capacitive vs Resistive Touch
Yuav Ua Li Cas Txhua Lub Tshuab Ua tiav (lossis poob) qhov tseeb
Capacitive kov cia siab rau kev sib cuam tshuam algorithms thoob plaws qhov ntsuas hluav taws xob rau qhov chaw raug zoo. Resistive kov yog nyob ntawm qhov sib xws ntawm ITO txheej thiab kev faib tawm siab sib xws.
Qhov Twg Txhua Tus Ua Tsis Tau
Capacitive cov ntxaij vab tshaus feem ntau poob qhov tseeb ntawm cov npoo, nrog cov yeeb yaj kiab dej, lossis thaum siv hnab looj tes. Cov ntxaij vab tshaus muaj peev xwm ua rau muaj kev sib tw linearity nyob rau hauv hnyav ntev - siv sijhawm.

7 TFT LCD Xim Zaub thiab cov khoom zais zais uas cuam tshuam rau qhov tseeb kov
Npog iav Thickness thiab nws cuam tshuam rau Kov Offset
Thicker tiv thaiv iav tsub kom parallax yuam kev ntawm lub qhov muag pom thiab qhov tseeb kov point. Kev sib txuas kho qhov muag ua rau txo qhov teeb meem no, txo qis parallax los ntawm 1.5-2mm hauv cov huab cua ib txwm- qhov sib txawv tsim kom qis dua 0.3mm raws li cov ntaub ntawv kho qhov muag.
Kub, Humidity, thiab Kov Accuracy Drift
Qhov ntsuas kub hloov pauv hloov ITO qhov tseem ceeb, thaum cov av noo cuam tshuam nrog kev nkag siab ntawm qhov chaw. Dav - qhov kub thiab txias modules nrog cov ntaub ntawv ruaj khov tswj tau zoo dua kov linearity LCD kev ua haujlwm thoob plaws kev ua haujlwm.
Controller IC Zoo thiab Calibration Algorithms
Kov maub los IC thiab nws cov txheej txheem interpolation muaj qhov cuam tshuam loj tshaj plaws ntawm qhov tseeb kawg. Factory calibration siv 9-point los yog 25-point txoj kev muab cov txiaj ntsig zoo dua li qhov yooj yim 4-point calibration, tshwj xeeb tshaj yog rau cov ntsiab lus kov ntau.
Lub LCD vaj huam sib luag tsuas yog ib feem ntawm zaj dab neeg - maub los zoo thiab calibration feem ntau txiav txim siab seb qhov tseeb raug tuav tom qab rau lub hlis ntawm kev xa tawm tiag.

Hauv tag nrho cov xwm txheej no, kev nqis peev hauv kev txheeb xyuas qhov tseeb ua rau txo qis qhov tsis ua hauj lwm hauv cheeb tsam thiab ntev - cov nqi them nyiaj yug.
Yuav ua li cas kom paub meej kov qhov tseeb thaum Sourcing los ntawm ib lub chaw tsim khoom lossis lub Hoobkas
Thaum ua haujlwm nrog cov chaw tsim khoom siv dej tsis sib haum, cov khoom lag luam kov tau raug, lossis 7 nti kov cov khoom lag luam, thov cov tsib yam tseem ceeb no:
Linearity yuam kev thoob plaws thaj chaw ua haujlwm (center thiab ntug)
Repeatability thiab hysteresis specifications
Qhov tseeb ntawm lub hom phiaj (kub, av noo, hnab looj tes, dej)
Calibration method thiab tus naj npawb ntawm cov ntsiab lus calibration
Long -cov ntaub ntawv xeem drift
Tsis txhob nug "qhov tseeb yog dab tsi?" - thov kom tiav daim ntawv tshaj tawm kev xeem, cov ntsiab lus ntawm cov txheej txheem calibration, thiab kev lees paub tias qhov tseeb yog lav ntawm cov npoo, tsis yog qhov chaw nruab nrab xwb.
Rau cov qauv siv tau, siv 9-grid lossis 25-grid xeem nyob rau hauv koj cov kev ua haujlwm tiag tiag, ntsuas qhov sib txawv ntawm ntau lub ntsiab lus nrog cov cuab yeej ntsuas.
Cov ntawv pov thawj thiab cov qauv uas muaj peev xwm ua tau raws li qhov tseeb kov qhov kev thov
Cov qauv tseem ceeb suav nrog IEC 62977 (kev ntsuas kev ntsuas), ISO 9241-411 (ergonomics ntawm kov interfaces), MIL-STD-461 (EMC cuam tshuam rau kev ua haujlwm), thiab IP kev ntsuas nrog kev tswj hwm kev ua haujlwm. Daim ntawv thov kev kho mob siv IEC 60601 series clauses ntawm kev siv tau thiab raug.
