doel
Verseker dat die produkte van die maatskappy aan die vereistes van die kliënt voldoen, die basis bied vir die inspeksie van produkte en die kwaliteit van die produk.
Omvang van die toepassing
Hierdie standaard is van toepassing op alle TFT-moduleprodukte wat deur XX vervaardig word.
Toets toerusting
Elektriese meetmasjien, toetsapparaat, vergrootglas, fluoresserende lamp, skuifkaliper
Monsternemingsplan en kontroleer die omgewingstoestande
Die vervaardigingseenheid (of proses QC) doen volledige inspeksie vir voorkomsinspeksie en elektriese prestasietoets, en vir grootte meting of spesiale inspeksie word die eerste stuk van elke model 5 stuks getoets en getoets.
Die kwaliteitseenheid meet 5 stuks vir die eerste monster van elke model, en aanvaar die GB / —2012 normale inspeksie-eenmalige steekproefplan vir die voorkomsinspeksie, en die algemene inspeksievlak is II.

Die eksaminator moet 'n elektrostatiese ring en agt vingerbedjies aan beide hande dra. As dit 'n LCD is sonder 'n polarisator, moet alle vingers vingerbedjies dra.
Die eksaminator kan die filmvergelykingstabel visueel nagaan of vergelyk.
Raadpleeg die monster vir die elektriese toets met behulp van die toetsinrigting en die skerm.
Die afstand tussen die inspekteur se oë en die produk is 30 ~ 40 cm. Die inspeksiehoek is ± 15 grade op die voorkant van die vertikale vertoonpaneel en ± 45 grade op die voorkant van die horisontale vertoonpaneel (sien die onderstaande figuur)
Omgewingsbeligting: 800 ～ 1200LUX vir visuele inspeksie
Omgewingstemperatuur: 25 ± 5 ℃
Humiditeit: 25 ~ 75% RH

(1) Definisie van puntdefekte wat deur interne panele veroorsaak word.
a) Helder kolle: helder, kolletjies met konstante grootte verskyn op die LCD onder die swart patroon.
b) Donker kolletjies: In die suiwer rooi, groen en blou prente verskyn donker kolletjies met dieselfde grootte op die LCD.
c) 2 aangrensende punte = 1 paar = 2 punte.
