Nyob rau niaj hnub no lub sijhawm ntawm kev coj noj coj ua uas nrov tshaj plaws, lub teeb selfie thiab sau cov khoom siv teeb pom kev zoo tau dhau los ua cov cuab yeej tseem ceeb rau cov neeg nyiam selfie vim lawv qhov kev txav tau yooj yim thiab siv tau, thiab kuj yog ib qho ntawm cov khoom tawg hauv kev hla ciam teb e-lag luam thiab kev lag luam tawm txawv teb chaws.
Raws li hom tshiab ntawm cov khoom siv teeb pom kev zoo, lub teeb selfie muaj ntau hom, feem ntau muab faib ua peb pawg: handheld, desktop, thiab bracket. Handheld selfie teeb yog lub teeb yuag thiab nqa tau yooj yim, haum rau siv sab nraum zoov lossis mus ncig; Desktop selfie teeb yog tsim los siv rau hauv qhov chaw ruaj khov xws li tsev lossis chaw ua haujlwm; Lub bracket style selfie teeb sib txuas ua haujlwm ntawm tus pas selfie thiab lub teeb sau, ua kom yooj yim rau cov neeg siv thaij duab los ntawm ntau lub kaum ntse ntse. Cov khoom sib txawv ntawm cov khoom siv selfie yog tsim rau cov xwm txheej sib txawv, xws li nyob streaming, cov yeeb yaj kiab luv luv, pawg duab selfie, thiab lwm yam.
Raws li kev lag luam tawm txawv teb chaws thiab kev muag khoom, cov qauv ua raws li kev tshuaj xyuas tus kheej portrait teeb kuj sib txawv.
IEC tus qauv: Tus qauv tsim los ntawm International Electrotechnical Commission (IEC), uas tsom mus rau kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom. Cov khoom lag luam ntawm tus kheej portrait yuav tsum ua tau raws li cov qauv kev nyab xeeb ntsig txog cov teeb thiab cov khoom siv teeb pom kev zoo hauv IEC.
UL tus qauv: Hauv Teb Chaws Asmeskas kev lag luam, cov khoom siv lub teeb pom kev zoo yuav tsum ua tau raws li cov qauv kev nyab xeeb tsim los ntawm UL (Underwriters Laboratories), xws li UL153, uas piav qhia txog kev nyab xeeb ntawm cov teeb txawb uas siv cov hlua hluav taws xob thiab cov ntsaws ruaj ruaj li cov cuab yeej txuas.
Suav txheem: Suav teb chaws tus qauv GB7000 series, sib xws rau IEC60598 series, yog tus qauv kev nyab xeeb uas cov khoom lag luam selfie yuav tsum ua kom tau raws li thaum muag hauv Suav lag luam. Tsis tas li ntawd, Tuam Tshoj kuj tseem siv Tuam Tshoj Compulsory Certification System (CCC), uas yuav tsum tau tag nrho cov khoom siv hluav taws xob thiab hluav taws xob kom dhau CCC daim ntawv pov thawj thiaj li yuav muag hauv khw.
European Standard: EN (European Norm) yog tus qauv tsim los ntawm cov koom haum tsim qauv hauv ntau lub tebchaws nyob sab Europe. Tus kheej portrait teeb khoom nkag mus rau European lag luam yuav tsum ua tau raws li cov kev cai hais txog cov teeb thiab cov khoom siv teeb pom kev zoo hauv EN tus qauv.
Japanese Industrial Standards(JIS) yog tus qauv kev lag luam hauv Nyij Pooj uas yuav tsum muaj cov khoom lag luam teeb pom kev zoo kom ua tau raws li cov kev cai ntawm JIS cov qauv thaum muag hauv khw hauv Nyij Pooj.
Los ntawm qhov kev xav ntawm kev soj ntsuam thib peb, cov ntsiab lus tseem ceeb ntawm kev tshuaj xyuas cov khoom lag luam rau lub teeb selfie suav nrog:
Lub teeb pom kev zoo: Tshawb xyuas seb lub teeb pom kev zoo li cas, tsis muaj qhov tsaus ntuj lossis ci ntsa iab, kom ntseeg tau tias cov nyhuv tua.
Roj teeb kev ua tau zoo: Kuaj roj teeb endurance thiab them ceev kom ntseeg tau tias cov khoom ruaj khov.
Cov khoom siv durability: Xyuas seb cov khoom siv puas ruaj khov thiab ruaj khov, tuaj yeem tiv taus qee qhov kev poob thiab nyem.
Kev ncaj ncees ntawm cov khoom siv: Xyuas seb cov khoom siv khoom puas ua tiav, xws li cov xov hlau them, cov hlua khi, thiab lwm yam.
Cov txheej txheem tshuaj xyuas thib peb feem ntau muab faib ua cov kauj ruam hauv qab no:
Lub thawv sampling: Randomly xaiv ib tus lej ntawm cov qauv ntawm cov khoom batch rau kev tshuaj xyuas.
Kev tshuaj xyuas qhov tshwm sim: Ua ib qho kev soj ntsuam zoo ntawm tus qauv kom tsis muaj qhov tsis xws luag lossis khawb.
Kev sim ua haujlwm: Ua cov kev ntsuas kev ua haujlwm ntawm cov qauv, xws li ci ntsa iab, xim kub, roj teeb lub neej, thiab lwm yam.
Kev soj ntsuam kev nyab xeeb: Ua kev ntsuas kev nyab xeeb ntawm cov qauv, xws li kev nyab xeeb hluav taws xob, hluav taws kub tsis kam, thiab nplaim hluav taws.
Kev tshuaj xyuas ntim khoom: xyuas seb cov khoom ntim puas tiav thiab tsis muaj kev puas tsuaj, nrog cov cim meej thiab cov khoom siv tiav.
Sau thiab tshaj tawm: Sau cov txiaj ntsig kev tshuaj ntsuam hauv ib daim ntawv thiab muab cov lus qhia ntxaws ntxaws.
Rau cov khoom lag luam selfie teeb, thaum lub sijhawm tshuaj xyuas, cov neeg soj ntsuam yuav ntsib cov teeb meem zoo hauv qab no, uas feem ntau hu ua qhov tsis xws luag:
Cov tsos mob tshwm sim: xws li khawb, xim sib txawv, deformations, thiab lwm yam.
Kev ua haujlwm tsis zoo: xws li qhov ci tsis txaus, xim kub sib txawv, tsis muaj peev xwm them, thiab lwm yam.
Cov teeb meem kev nyab xeeb: xws li hluav taws xob muaj kev nyab xeeb, cov khoom siv hluav taws xob, thiab lwm yam.
Cov teeb meem ntim khoom: xws li cov ntim khoom puas, daim ntawv tsis pom kev, cov khoom siv uas ploj lawm, thiab lwm yam.
Hais txog cov khoom tsis xws luag, cov neeg soj ntsuam yuav tsum tau sau tam sim thiab muab cov lus tawm tswv yim rau cov neeg siv khoom thiab cov chaw tsim khoom txhawm rau kho thiab txhim kho cov khoom zoo raws sijhawm.
Kev paub txog kev paub thiab kev txawj ntse ntawm tus kheej portrait teeb cov khoom tshuaj xyuas yog qhov tseem ceeb rau kev ua haujlwm zoo hauv kev tshuaj xyuas thiab ua kom cov khoom zoo ntawm cov neeg siv khoom. Los ntawm cov ncauj lus kom ntxaws tsom xam thiab qhia txog cov ntsiab lus saum toj no, Kuv ntseeg tias koj tau nkag siab tob txog kev tshuaj xyuas cov khoom lag luam teeb pom kev zoo. Hauv kev ua haujlwm zoo, nws yog qhov yuav tsum tau hloov kho thiab ua kom zoo dua cov txheej txheem tshuaj xyuas thiab cov txheej txheem raws li cov khoom tshwj xeeb thiab kev xav tau ntawm kev lag luam.
