Sinov spetsifikatsiyasi

maqsad

Kompaniyaning mahsulotlarini mijozlar talablariga javob berishini, mahsulotni tekshirish uchun asos yaratilishini va mahsulot sifatini ta'minlashni ta'minlash.

Qo'llash sohasi

Ushbu standart XX tomonidan ishlab chiqarilgan barcha TFT moduli mahsulotlariga tegishli.

Sinov uskunalari

Elektr o'lchash apparati, sinov moslamasi, lupa, lyuminestsent chiroq, vernier kaliperi

Namuna olish rejasi va atrof-muhit sharoitlarini tekshirish

Ishlab chiqarish birligi (yoki jarayon QC) tashqi ko'rinishini tekshirish va elektr samaradorligini sinash uchun to'liq tekshiruvni amalga oshiradi va o'lchamlarni o'lchash yoki maxsus tekshirish uchun har bir modelning birinchi bo'lagi namuna olinadi va 5 dona sinovdan o'tkaziladi.

Sifat birligi har bir modelning birinchi namunasi uchun 5 donani o'lchaydi va tashqi ko'rinishini tekshirish uchun GB / —2012 normal tekshiruvning bir martalik namunaviy rejasini qabul qiladi va umumiy tekshirish darajasi II ga teng.

Tekshiruvchi elektrostatik uzuk va ikkita qo'lida sakkizta barmoq karyolasini kiyishi kerak, agar u polarizator biriktirilmagan LCD bo'lsa, barcha barmoqlar barmoq karyolasini kiyishi kerak.

Tekshiruvchi vizual ravishda tekshirishi yoki filmlarni taqqoslash jadvali bilan taqqoslashi mumkin.

Iltimos, sinov moslamasi va displey ekrani yordamida elektr sinovi uchun namunaga murojaat qiling.

Inspektorning ko'zlari bilan mahsulot o'rtasidagi masofa 30 ~ 40 sm. Tekshiruvni ko'rish burchagi vertikal displey panelining old yuzasida ± 15 daraja va gorizontal displey panelining old yuzasida ± 45 daraja (quyidagi rasmga qarang).

Atrof muhitni yoritish: vizual tekshirish uchun 800 ~ 1200LUX

Atrof muhit harorati: 25 ± 5 ℃

Namlik: 25 ~ 75% RH

Ob'ektni tekshiring

(1) Ichki panellardan kelib chiqqan nuqson nuqsonlarining ta'rifi.

a) Yorqin dog'lar: LCD displeyda qora naqsh ostida yorqin, doimiy o'lchamdagi nuqtalar paydo bo'ladi.

b) qorong'u nuqtalar: toza qizil, yashil va ko'k rangdagi rasmlarda LCD displeyda bir xil o'lchamdagi quyuq nuqtalar paydo bo'ladi.

v) ulashgan 2 ball = 1 juft = 2 ball.
