xedea
Ziurtatu enpresaren produktuek bezeroen eskakizunak betetzen dituztela, produktuak ikuskatzeko oinarriak eskaintzen dituztela eta produktuaren kalitatea bermatzen dutela.
Aplikazio eremua
Arau hau XX-k sortutako TFT moduluen produktu guztiei aplikatzen zaie.
Saiakuntza Ekipamendua
Neurtzeko makina elektrikoa, probatzeko aparatua, lupa, lanpara fluoreszentea, kalabaza
Laginketa plana eta ingurumen baldintzak egiaztatu
Fabrikazio-unitateak (edo QC prozesuak) ikuskapen osoa egiten du itxura ikuskatzeko eta errendimendu elektrikoaren probetarako, eta tamaina neurtzeko edo ikuskapen berezia egiteko, modelo bakoitzaren lehen pieza 5 pieza probatu eta probatu da.
Kalitate unitateak 5 pieza neurtzen ditu modelo bakoitzeko lehen laginerako, eta GB / —2012 ikuskapen arruntaren laginketa bakarra hartzen du itxura ikuskatzeko, eta ikuskapen maila orokorra II da.

Aztertzaileak eraztun elektrostatikoa eta bi eskuetako zortzi hatz jantzi behar ditu. Polarizatzailerik erantsita ez duen LCDa bada, hatz guztiek hatzetako sehaskak eraman beharko dituzte.
Aztertzaileak ikusmenean edo filmarekin alderatzeko taularekin alderatu dezake.
Mesedez, jo ezazu laginera proba elektrikoetarako probarako aparatua eta pantaila pantaila erabiliz.
Ikuskariaren begien eta produktuaren arteko distantzia 30 ~ 40 cm-koa da. Ikuskapenaren angelua ± 15 gradu da bistaratze-panel bertikalaren aurrealdean eta ± 45 gradu bistaratze-panel horizontalaren aurrealdean (ikus beheko irudia)
Ingurumeneko argiztapena: 800 ～ 1200LUX ikusizko ikuskapenerako
Ingurumenaren tenperatura: 25 ± 5 ℃
Hezetasuna: 25 ~ 75% RH
Egiaztatu elementua
(1) Barruko panelek eragindako akats puntualen definizioa.
a) Leku argiak: tamaina konstanteko puntu distiratsuak agertzen dira LCD eredu beltzaren azpian.
b) Puntu ilunak: gorri, berde eta urdin irudietan, tamaina bereko puntu ilunak agertzen dira LCDan.
c) 2 puntu aldamenean = 1 bikote = 2 puntu.
