Speċifikazzjoni tat-Test

għan

Tiżgura li l-prodotti tal-kumpanija jissodisfaw ir-rekwiżiti tal-klijenti, jipprovdu bażi għall-ispezzjoni tal-prodott, u jiżguraw il-kwalità tal-prodott.

Skop ta 'applikazzjoni

Dan l-istandard japplika għall-prodotti kollha tal-modulu TFT prodotti minn XX.

Tagħmir għall-Ittestjar

Magna tal-kejl elettrika, apparat tat-test, lenti, lampa fluworexxenti, kaliper vernier

Pjan ta 'teħid ta' kampjuni u ċċekkja l-kundizzjonijiet ambjentali

L-unità tal-manifattura (jew proċess tal-QC) twettaq spezzjoni sħiħa għall-ispezzjoni tad-dehra u t-test tal-prestazzjoni elettrika, u għall-kejl tad-daqs jew spezzjoni speċjali, l-ewwel biċċa ta 'kull mudell hija meħuda bħala kampjun u ttestjata 5pcs.

L-unità ta 'kwalità tkejjel 5pcs għall-ewwel kampjun ta' kull mudell, u tadotta l-pjan ta 'kampjunar ta' darba GB / —2012 ta 'spezzjoni normali għall-ispezzjoni tad-dehra, u l-livell ta' spezzjoni ġenerali huwa II.

L-eżaminatur jeħtieġ li jilbes ċirku elettrostatiku u tmien kerrikots tas-swaba 'fuq iż-żewġ idejn. Jekk huwa LCD mingħajr polarizzatur imwaħħal, is-swaba' kollha għandhom jilbsu kerrikots tas-swaba '.

L-eżaminatur jista 'jiċċekkja viżwalment jew iqabbel mat-tabella tal-paragun tal-film.

Jekk jogħġbok irreferi għall-kampjun għat-test elettriku billi tuża apparat tat-test u display screen.

Id-distanza bejn għajnejn l-ispettur u l-prodott hija 30 ~ 40 cm. L-angolu tal-vista tal-ispezzjoni huwa ta '± 15-il grad fuq il-wiċċ ta' quddiem tal-pannell tal-wiri vertikali u ± 45 grad fuq il-wiċċ ta 'quddiem tal-pannell tal-wiri orizzontali (ara l-figura hawn taħt)

Iċċekkja l-oġġett

(1) Definizzjoni ta 'difetti puntwali kkawżati minn pannelli interni.

a) Tikek qawwi: tikek tleqq u ta 'daqs kostanti jidhru fuq l-LCD taħt il-mudell iswed.

b) Tikek skuri: Fl-istampi ħomor, ħodor u blu puri, tikek skuri bl-istess daqs jidhru fuq l-LCD.

c) 2 punti biswit = 1 par = 2 punti.
