Ib, Technical txoj cai: Lub hauv paus kev koom ua ke ntawm LCD zaub thiab kov tswj
Lub hauv paus ntsiab lus tseem ceeb ntawm lub vijtsam tawg yog los tso saib cov lej thiab cov cim los ntawm kev tswj cov deflection ntawm cov kua siv lead ua kua molecules. Nws cov qauv muaj ob txheej ntawm iav substrates, cov kua siv lead ua kua, txheej electrode, thiab polarizer. Cov "segment" tshwj xeeb yog tsav los ntawm electrodes los tsim cov qauv ruaj xws li 0-9 thiab AZ. Piv txwv li, tus naj npawb "8" muaj 7 ntu ntawm kev ywj pheej, thiab kev hloov pauv digital los ntawm 0 mus rau 9 yog ua tiav los ntawm kev tswj qhov voltage ntawm txhua ntu.
Kev siv cov khawm ua haujlwm yog nyob ntawm kev sib koom ua ke ntawm cov cuab yeej kov. Cov tshuaj tiv thaiv kev ua txhaum cai ib txwm muaj tsuas yog muaj cov haujlwm ua haujlwm, tab sis los ntawm kev ntxiv cov txheej txheem pob tshab (xws li ITO zaj duab xis) ntawm lub iav substrate, capacitive lossis resistive kov circuits tuaj yeem tsim. Tshwj xeeb:
Capacitive kov: Deposition ntawm ib qho - txheej los yog ob npaug - txheej ITO electrodes ntawm iav nto los tsim ib qho chaw kov. Thaum tus ntiv tes kov lub vijtsam, qhov kev hloov pauv hauv cheeb tsam tau kuaj pom tias yog lub teeb liab tseem ceeb, uas muaj qhov zoo ntawm qhov siab rhiab heev thiab ntau qhov kov, tab sis tus nqi kuj yog siab heev.
Resistive kov: Kev tshawb nrhiav qhov tseem ceeb yog ua tiav los ntawm kev sib cuag lub cev ntawm ob txheej ntawm ITO zaj duab xis, nrog cov qauv yooj yim thiab tus nqi qis, tab sis tsis muaj zog, tsim nyog rau tsawg - zaus ua haujlwm zaus.
Kev txheeb xyuas qhov ua tau zoo: Kev ua lag luam kev ua haujlwm tau pom tias kev koom ua ke ntawm QR code screen thiab kov tswj tau ua tiav daim ntawv thov loj -. Piv txwv li, Yangrun Electronics tau kho lub 5-inch VA disconnect screen rau ib yam khoom siv kho mob, uas siv ob txheej ITO capacitive kov cov tshuaj thiab txhawb kev ua haujlwm kub ntawm -30℃txog 80 degree. Lub neej kov ncav cuag ntau dua 1 lab lub sijhawm, txheeb xyuas qhov kev loj hlob ntawm kev daws teeb meem.
2, Txoj Kev Ua Haujlwm: Kev txhawb nqa tag nrho los ntawm cov khoom lag luam mus rau kev sib sib zog nqus
Lub khawm customized ua haujlwm rau lub vijtsam tawg yuav tsum muaj plaub kauj ruam tseem ceeb: kev tsom xam, kev tsim qauv, xaiv cov khoom siv, thiab cov txheej txheem kev sib koom ua ke. Qhov kev sib tw tseem ceeb nyob hauv kev sib npaug ntawm kev ua haujlwm, tus nqi, thiab kev ntseeg siab.
1. Kev tsom xam thiab cov txheej txheem tsim
Customization ntawm cov ntsiab lus tso saib: Txiav txim siab cov zaub teb (xws li qhov kub thiab txias, lub sijhawm, cov xwm txheej icons) thiab khawm layout (xws li paub meej, tshem tawm, kho nce thiab nqis) raws li daim ntawv thov scenario. Piv txwv li, cov tswj hauv tsev ntse yuav tsum tso saib chav tsev kub thiab av noo, thiab nruab nrog cov khawm kov xws li "hom switching" thiab "cua nrawm hloov".
Interaction logic design: Txhais qhov kev sib txuas ntawm cov khawm ua haujlwm thiab tso saib cov ntsiab lus. Piv txwv li, ntev nias lub khawm "Hom" hloov ntawm hom txias / cua sov, thiab nias luv luv los kho lub hom phiaj kub.
Environmental adaptability yuav tsum: Cov cuab yeej siv yuav tsum txhawb kev ua haujlwm kub ntawm -40℃mus rau 85 degree, cov khoom siv kho mob yuav tsum ua tau raws li IP67 waterproof, thiab cov khoom siv sab nraum zoov yuav tsum tiv taus UV aging.
2. Cov qauv thiab cov khoom siv xaiv
Iav substrate: Tshuaj muaj zog iav (xws li Corning Gorilla Glass) raug xaiv los txhim kho kev cuam tshuam, nrog lub thickness tswj ntawm 0.5-1.1mm kom sib npaug kov rhiab heev thiab lub zog ntawm cov qauv.
Txheej txheej: Capacitive kov siv ib zaug - txheej ITO (tus nqi qis) lossis ob npaug - txheej ITO (siab rhiab heev), thaum kov kov siv indium tin oxide (ITO) zaj duab xis lossis hlau mesh.
Backlight module: Xaiv LED sab nraub qaum lossis tag nrho cov teeb pom kev zoo raws li lub teeb pom kev nyob ib puag ncig, nrog qhov ci ci tsawg kawg yog 300cd / m ² kom ntseeg tau tias sab nraum zoov pom.
3. Txheej txheem kev koom ua ke thiab kev kuaj xyuas
Kov thaiv kev tsim: Muab cov pins kov ntawm ntug ntawm lub iav substrate thiab txuas rau lawv mus rau lub motherboard los ntawm FPC (lub rooj tsav xwm hloov tau yooj yim) kom tsis txhob muaj teeb meem cuam tshuam.
Cov txheej txheem ntim khoom: COG (Chip on Glass) lossis COF (Chip on Film) thev naus laus zis yog siv los khi tus tsav tsheb IC rau iav substrate, txo cov ntim ntim.
Kev ntsuam xyuas kev ntseeg tau: Txheeb xyuas qhov kev ruaj ntseg ntawm lub module los ntawm kev kub siab thiab qis qis (-40℃txog 85 degree), ntsev tshuaj tsuag (48 teev), thiab kev vibration test (5-500Hz).
Kev lag luam rooj plaub: Ningbo Xuda Electronics kho lub 3.2-inch STN disconnect screen rau cov cuab yeej siv, kev sib koom ua ke 4 capacitive kov nyees khawm thiab txais yuav ib txheej ITO thaiv kev tsim. Los ntawm optimizing lub electrode layout, cov nyiaj muab tshuaj txhuam tau txo los ntawm 20%, thiab ua ke nrog bulk purchase ntawm iav substrates, tus nqi raug txo los ntawm 15%. Thaum kawg, chav tsev tus nqi tau tswj ntawm 4.2 yuan / thooj, uas yog 18% qis dua qhov kev lag luam nruab nrab hais.
3, Kev lag luam daim ntawv thov: dav dav los ntawm cov neeg siv khoom siv hluav taws xob mus rau siab -kev tsim khoom kawg
Lub pob customized ua haujlwm ntawm lub vijtsam tawg tau nkag mus rau ntau qhov chaw sub, thiab nws cov txiaj ntsig tseem ceeb nyob rau hauv kev txhim kho cov neeg siv kev paub thiab qib kev txawj ntse los ntawm kev tsim qauv ntawm "duab + kev sib cuam tshuam".
1. Ntse Tsev: Sib tham sib hloov kho ntawm Tswj Vaj Huam Sib Luag
Daim ntawv thov scenarios: Tswj vaj huam sib luag rau cua txias, tshuab cua tshiab, ntse qhov rooj xauv, thiab lwm yam khoom siv.
