Kev ntsuas qhov ntsuas

lub hom phiaj

Ua kom ntseeg tau tias lub tuam txhab cov khoom lag luam ua tau raws li cov neeg siv khoom, muab lub hauv paus rau kev tshuaj xyuas cov khoom lag luam, thiab xyuas kom cov khoom zoo.

Cov tau txais daim ntawv thov

Cov qauv no siv rau txhua TFT cov khoom lag luam tsim tawm los ntawm XX.

Cov Khoom Siv Soj Ntsuam

Lub tshuab ntsuas lub tshuab hluav taws xob, kuaj hluav taws xob, ntsuas lub khob iav, lub teeb roj fluorescent, vernier caliper

Qauv npaj thiab kuaj cov teeb meem ib puag ncig

Lub chaw tsim khoom (lossis cov txheej txheem QC) ua qhov ntsuas tag nrho rau kev tshuaj ntsuam thiab ntsuas qhov ntsuas hluav taws xob, thiab rau kev ntsuas loj lossis ntsuas tshwj xeeb, thawj daim ntawm txhua tus qauv yog kuaj thiab kuaj 5pcs.

Cov khoom ntsuas zoo ntsuas 5pcs rau thawj qhov qauv ntawm txhua tus qauv, thiab saws GB / —2012 kev soj ntsuam ib txwm kuaj ib zaug qauv rau kev soj ntsuam cov tsos, thiab qib ntsuas kev soj ntsuam dav dav yog II.

Tsis tsim nyog qib Qib uas tso cai (AQL) Ntsig txog kev ntsuas tus qauv zoo
Lub cev tsis muaj peev xwm   Yog hais tias qhov loj tsis zoo, 0 tau txais 1 rov qab

tag nrho

Tus neeg kuaj yuav tsum hnav lub nplhaib electrostatic thiab yim ntiv tes ntiv tes ntawm ob txhais tes.Yog hais tias nws yog LCD uas tsis muaj lub polarizer txuas, txhua tus ntiv tes yuav tsum hnav ntiv tes cots.

Cov ntawv xeem tuaj yeem pom los yog saib lub rooj sib piv ntawm zaj duab xis.

Thov xa mus rau cov qauv coj mus rau qhov ntsuas hluav taws xob uas siv cov khoom siv ntsuas thiab ntsuas tshuaj ntsuam.

Qhov kev ncua deb ntawm tus neeg kuaj xyuas lub qhov muag thiab khoom yog 30 ~ 40 cm. Kev soj ntsuam saib lub kaum ntse ntse yog ± 15 degrees nyob rau sab pem hauv ntej ntawm lub vaj huam sib luag rau txoj kab ntsug thiab on 45 degrees ntawm qhov chaw ua ntej ntawm cov kab rov tav ua vaj huam sib luag (saib daim duab hauv qab)

Chaw teeb pom kev zoo ib puag ncig: 800 ~ 1200LUX rau kev kuaj pom

Ib puag ncig kub: 25 ± 5 ℃

Vaum: 25 ~ 75% RH

Tshawb cov khoom

(1) Cov ntsiab lus ntawm qhov taw tes tsis xws luag los ntawm cov phiaj xwm sab hauv.

a) Cov duab ci ntsa iab: lub teeb ci ntsa iab, tas li-qhov pom tshwm ntawm lub LCD raws cov qauv dub.

b) Cov dot tsaus nti: Hauv cov ntshiab xim liab, ntsuab, thiab xiav, duab tsaus nti nrog cov loj tib yam tshwm sim ntawm LCD.

c) 2 cov ntsiab lus nyob ib sab = 1 khub = 2 ntsiab lus.
