Industrial Quality TFT Display Requirements

1. Kev ntseeg tau ntawm cov khoom

Feem ntau ntawm cov duab LCD yog tsim los rau cov neeg siv khoom siv xws li smartphones, koob yees duab, ntsiav tshuaj computers, thiab cov khoom siv ua si. Tab sis lawv muaj cov kev xav tau sib txawv dua li cov kev siv rau kev lag luam. Vim yog tus nqi sib tw heev thiab cov voj voog ntau lawm, cov neeg siv khoom siv cov khoom siv tsis tas yuav suav nrog cov kav ntev, kev ntseeg siab, thiab cov yam ntxwv siab heev uas yuav tsum muaj kom muaj sia nyob hauv ib puag ncig kev lag luam. Cov khoom lag luam lub neej voj voog kuj feem ntau luv dua hauv cov neeg siv khoom siv. Cov ntxaij vab tshaus tsim rau cov ntawv thov no feem ntau tsuas yog muaj rau ib qho, hauv qhov zoo tshaj plaws ob xyoos. Nyob rau hauv sib piv, tso saib modules rau industrial daim ntaub ntawv yuav tsum tau ntev cov khoom lub neej voj voog - feem ntau mus txog kaum xyoo los yog ntau tshaj. Ntxiv rau, thaum ib qho kev lag luam module raug txiav tawm los ntawm cov chaw tsim khoom, cov khoom lag luam yuav tsum tau rov qab-tshaj li kom haum rau hauv cov ntaub ntawv uas twb muaj lawm yam tsis tas yuav rov tsim kho tag nrho cov kab ke.


2. Kev ua haujlwm ib puag ncig

Lub peev xwm tiv taus qhov kub thiab txias thiab kev poob siab thiab kev vibration kuj yog ib qho tseem ceeb rau kev txiav txim siab thaum xaiv cov khoom siv niaj hnub no. Lawv yuav tsum muaj zog txaus los tiv thaiv kev sib tsoo los yog jiggles los ntawm cov neeg tsav tsheb thiab cov khoom siv nyob ib puag ncig, thiab tseem yuav tsum muaj peev xwm tswj tau ntau yam kev ua haujlwm kub.

Dav kev ua haujlwm kub

Cov khoom lag luam feem ntau yog nyob hauv ib lub thawv uas yog ib feem ntawm cov khoom siv loj dua. Nyob rau hauv cov xwm txheej no, cov cua sov uas tsim los ntawm cov khoom siv nyob ib puag ncig tau raug daig hauv qhov chaw kaw, uas tuaj yeem ua rau muaj kev puas tsuaj rau ntau qhov chaw. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum khaws cia qhov tseeb thiab kev ua haujlwm kub hauv siab thaum xaiv cov zaub. Thaum cov kev ntsuas tuaj yeem raug coj los ua kom cov cua sov tsim tawm - xws li siv cov kiv cua hauv lub thawv - txoj hauv kev zoo tshaj plaws los xyuas kom muaj kev ua raws li kev cia thiab kev ua haujlwm kub yog xaiv cov zaub uas zoo rau cov hom kev kawm no. Hmoov zoo, kev txhim kho hauv cov ntaub ntawv ua kua siv lead ua tau ua rau nws muaj peev xwm txuas ntxiv kev ua haujlwm kub ntawm LCDs ntawm -30 txog 80 degree tam sim no.

Shock, Vibration, EMI thiab Mechanical Damage

Feem ntau, cov khoom siv hauv kev lag luam yuav tsum muaj rugged ntau dua piv rau cov khoom siv txheem. Kev txo tus naj npawb ntawm tus pin thiab lub qhov (socket connectors) thiab qhia cov chip-on-glass semiconductors yog ib txoj hauv kev ua kom muaj kev poob siab ntau dua thiab kev co. Tsis tas li ntawd, kev txhim kho hlau bezels es tsis txhob siv cov khoom yas pab txhim kho lub tsev EMI cov yam ntxwv thiab kev ua haujlwm tsis zoo. Ntxiv tshuaj ntxiv dag zog rau pem hauv ntej iav pab kom tsis txhob khawb thiab blemishes ntawm tus neeg siv nto.

3. Nyeem tau

Brightness

Nws yog ib qho tseem ceeb uas cov lus qhia siv nyob rau hauv cov ntawv thov kev lag luam txhawb kev pom meej thiab meej los ntawm ntau lub ces kaum nyob rau hauv ntau yam teeb pom kev zoo. Qhov ci ntsa iab ntawm ib puag ncig, qhov nyuaj dua nws tuaj yeem nyeem tau tus qauv transmissive LCD zaub nrog qhov ci ci ntawm 250 txog 300 cd / m2. NVD tau tsim cov lus qhia uas tuaj yeem ua tau hauv 800-cd / m2- thiab ntau dua los ntawm kev siv cov LEDs muaj txiaj ntsig zoo rau chav teeb pom kev rov qab - yog tias tsim nyog, ua ke nrog cov yeeb yaj kiab tshwj xeeb txhim kho qhov ci.

Qhov sib piv piv

Ua kom cov zaub qhov sib piv piv yog lwm txoj hauv kev zoo uas cov chaw tsim khoom tuaj yeem txhim kho cov duab nyeem hauv qhov chaw ci ntsa iab. Qhov sib piv zoo sib piv rau cov khoom tsis yog kev lag luam yog nyob rau hauv thaj tsam ntawm 200: 1 txog 300: 1, uas tej zaum yuav tsis txaus thaum tus neeg teb xov tooj tau saib cov zaub los ntawm qhov deb. Cov lus pom nrog qhov sib piv ntawm 500: 1 lossis ntau dua yog qhov zoo dua rau kev lag luam ib puag ncig. Lwm qhov txiaj ntsig ntawm txoj kev no yog tias nws tsis nce lub zog siv.

Transflective LCDs

Transflective LCDs yog ib qho kev daws teeb meem zoo rau ib puag ncig nrog lub teeb pom kev sib txawv. Muaj ob qho tib si transmissive thiab reflective yam ntxwv, transflective LCDs muaj kev xaiv los ntawm kev siv lub backlight nyob rau hauv dim teeb pom kev zoo (hom transmissive), nrog rau siv cov khoom reflective nyob rau hauv lub teeb pom kev zoo (reflective hom). Qhov no txo ​​qis kev siv hluav taws xob thiab hluav taws xob ntau lawm hauv hom kev cuam tshuam vim tsis siv lub teeb rov qab.

Saib cov ces kaum

Multi-angle readability yog lwm qhov tseem ceeb xaiv qhov tseem ceeb. Nyob rau hauv ib qho kev lag luam ib puag ncig, tus neeg teb xov tooj lub tshuab muaj feem ntau yuav tsum tau muab tso rau ntawm lub kaum sab xis es tsis yog nyob rau pem hauv ntej ntawm lub vijtsam. Kev siv cov zaub tsim los rau cov neeg siv khoom siv feem ntau tsis ua haujlwm zoo hauv qhov xwm txheej no, vim tias muaj cov duab distortion thiab xim hloov thaum saib ntawm lub kaum sab xis. Txawm li cas los xij, ntau cov thev naus laus zis tau ua haujlwm los txhim kho qhov pom ntawm lub kaum sab xis hauv cov duab, ua rau lawv tsim nyog rau kev siv hauv kev lag luam. Qee cov thev naus laus zis ua yeeb yaj kiab ua rau pom cov kaum sab xis ntawm 160º kab rov tav thiab 140º ntsug, tab sis qee qhov, qhov no tseem tsis txaus. Nyob rau hauv dav hlau hloov tshuab (IPS), multi-domain vertical alignment (MVA), thiab fringe teb switching (FFS) muaj lwm txoj kev. Cov thev naus laus zis no muaj peev xwm ua tiav qhov pom ntawm yuav luag 90-degrees mus rau tag nrho plaub cov lus qhia yam tsis muaj xim hloov.

Ntxiv qhov loj thiab kev daws teeb meem

Qhov loj me thiab kev daws teeb meem kuj tseem ua lub luag haujlwm hauv kev nyeem tag nrho. Cov lus qhia ntawm 2 thiab 25-inch kab pheeb ces kaum yog siv feem ntau hauv cov ntawv thov kev lag luam. Qhov ntau thiab tsawg no muab thaj chaw txaus los saib cov duab, waveforms, thiab lwm yam graphical cov ntaub ntawv yam tsis tas siv cov khoom vaj khoom tsev ntau dhau ntawm cov khoom siv.

Los ntawm qhov piv txwv 4: 3 pib, cov khoom lag luam tam sim no hloov mus rau ntau hom nrog WVGA rau WXGA daws teeb meem. Cov hom dav dav ua rau cov neeg siv tuaj yeem saib cov ntawv ntev dua thiab cov ntaub ntawv ntau dua ntawm ib qho zaub. Cov zaub modules no tseem tuaj yeem tsim los koom nrog cov haujlwm tseem ceeb, tso cai rau cov tuam txhab tsim khoom hla lub cev hloov pauv thiab cov nyees khawm thiab tsim HMIs raws li software ntau dua li kho vajtse.
