eesmärk
Veenduge, et ettevõtte tooted vastavad klientide nõuetele, loovad aluse toote kontrollimiseks ja tagavad toote kvaliteedi.
Kohaldamisala
See standard kehtib kõigi XX poolt toodetud TFT-moodulite toodete kohta.
Testimisseadmed
Elektriline mõõteseade, katseseade, luup, luminofoorlamp, vernieri nihik
Proovivõtuplaan ja kontrollige keskkonnatingimusi
Tootmisüksus (või protsessi kvaliteedikontroll) teostab väliskontrolli ja elektrilise jõudluse testi täieliku kontrolli ning suuruse mõõtmiseks või spetsiaalseks kontrollimiseks võetakse iga mudeli esimesest tükist proov ja proovitakse 5 tk.
Kvaliteediüksus mõõdab iga mudeli esimese proovi jaoks 5 tk ja võtab väljanägemise kontrollimiseks vastu GB / —2012 tavalise kontrolli ühekordse proovivõtuplaani ning üldine kontrollitase on II.

Eksamineerija peab mõlemal käel kandma elektrostaatilist rõngast ja kaheksat sõrmevoodit. Kui see on LCD-ekraan ilma polarisaatorita, peaksid kõik sõrmed kandma sõrmevoodeid.
Eksamineerija saab filmide võrdlustabelit visuaalselt kontrollida või võrrelda.
Palun vaadake prooviseadme ja ekraaniga elektrikatse näidist.
Inspektori silmade ja toote vaheline kaugus on 30 ~ 40 cm. Vaatlusnurk on vertikaalse kuvapaneeli esipinnal ± 15 kraadi ja horisontaalse ekraanipaneeli esipinnal ± 45 kraadi (vt allolevat joonist)
Keskkonna valgustus: visuaalseks kontrolliks 800 ～ 1200LUX
Keskkonna temperatuur: 25 ± 5 ℃
Niiskus: 25 ~ 75% suhteline õhuniiskus
Kontrollige üksust
(1) Sisepaneelide põhjustatud punktivigade määratlus.
a) Heledad laigud: LCD-ekraanile ilmuvad musta mustri alla heledad, konstantsed punktid.
b) Tumedad punktid: Punasel, rohelisel ja sinisel pildil on LCD-ekraanil sama suurusega tumedad punktid.
c) 2 kõrvuti asetsevat punkti = 1 paar = 2 punkti.

Remarks:
1. Ignore any defects on the protective film of the polarizer, such as scratches, bubbles and particles on the protective film.
2. The angle of all damage must be greater than 90 degrees as shown on the right.
3. If the customer has specified requirements according to customer requirements.
