Cynllun samplu a gwirio amodau amgylcheddol

Mae'r uned weithgynhyrchu (neu'r broses QC) yn cynnal arolygiad llawn ar gyfer archwilio ymddangosiad a phrawf perfformiad trydanol, ac ar gyfer mesur maint neu arolygiad arbennig, mae darn cyntaf pob model yn cael ei samplu a'i brofi 5cc.

Mae'r uned ansawdd yn mesur 5cc ar gyfer sampl gyntaf pob model, ac yn mabwysiadu cynllun samplu un-amser arolygu arferol GB / —2012 ar gyfer yr arolygiad ymddangosiad, a'r lefel arolygu gyffredinol yw II.

cyfanswm

Mae angen i'r arholwr wisgo modrwy electrostatig ac wyth cot bys ar ei ddwy law. Os yw'n LCD heb polarydd ynghlwm, dylai'r holl fysedd wisgo cotiau bys.

Gall yr arholwr wirio neu gymharu â'r tabl cymharu ffilm yn weledol.

Cyfeiriwch at y sampl ar gyfer y prawf trydanol gan ddefnyddio gosodiad prawf a sgrin arddangos.

Y pellter rhwng llygaid yr arolygydd a'r cynnyrch yw 30 ~ 40 cm. Mae ongl wylio'r arolygiad yn ± 15 gradd ar wyneb blaen y panel arddangos fertigol a ± 45 gradd ar wyneb blaen y panel arddangos llorweddol (gweler y ffigur isod)

Goleuadau amgylchedd: 800 ～ 1200LUX ar gyfer archwiliad gweledol

Tymheredd yr amgylchedd: 25 ± 5 ℃

Lleithder: 25 ~ 75% RH

(1) Diffiniad o ddiffygion pwynt a achosir gan baneli mewnol.

a) Smotiau llachar: mae dotiau llachar, maint cyson yn ymddangos ar yr LCD o dan y patrwm du.

b) Dotiau tywyll: Yn y lluniau coch, gwyrdd a glas pur, mae dotiau tywyll gyda'r un maint yn ymddangos ar yr LCD.

c) 2 bwynt yn gyfagos = 1 pâr = 2 bwynt.

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.
