Mayeso a Mayeso

cholinga

Onetsetsani kuti zinthu zomwe kampaniyo ikugulitsa zikugwirizana ndi zomwe makasitomala amafunikira, perekani maziko oyendera malonda, ndikuwonetsetsa kuti mankhwala ali abwino.

Kukula kwa ntchito

Mulingo uwu umagwira pazogulitsa zonse za TFT zopangidwa ndi XX.

Zida Zoyesera

Makina oyesera amagetsi, makina oyesera, galasi lokulitsira, nyali ya fulorosenti, chowongolera cha vernier

Zitsanzo zazitsanzo ndikuwunika momwe zachilengedwe zilili

Chipangizo chopangira (kapena QC) chimayang'ana kwathunthu pakuwunika ndi kuyesa kwa magwiridwe antchito amagetsi, ndikuyesa kukula kapena kuyang'anira kwapadera, chidutswa choyamba cha mtundu uliwonse chimayesedwa ndi ma 5pcs.

Gawo loyeserera limayesa ma 5pcs pachitsanzo choyambirira cha mtundu uliwonse, ndipo amatenga GB / -2012 kuyendera koyenera nthawi imodzi yazitsanzo zowunika, ndipo gawo loyang'anira ndi II.

Mulingo wosayenerera Mulingo wovomerezeka (AQL) Kuyenerera kwamachitidwe oyenerera
Chosowa chachikulu   Ngati kukula kwake kulibe vuto, 0 landirani 1 kubwerera
Kugonjera  
okwana

Woyesayo amafunika kuvala mphete yamagetsi ndi miphika isanu ndi itatu m'manja mwake.Ngati ndi LCD yopanda polarizer, zala zonse ziyenera kuvala mphasa zala.

Woyesayo amatha kuwona kapena kuyerekezera ndi tebulo lofanizira kanema.

Chonde onani zitsanzo za mayeso amagetsi pogwiritsa ntchito fixture ndi mawonekedwe owonetsera.

Mtunda pakati pa maso a woyang'anira ndi malonda ake ndi 30 ~ 40 cm. Mawonekedwe owonera ndi ± 15 madigiri kutsogolo kwa mawonekedwe owonekera ndi ± madigiri a 45 kutsogolo kwa mawonekedwe owonetsera (onani chithunzi pansipa)

Kuunikira kwachilengedwe: 800 ~ 1200LUX kuti muwone zowoneka

Kutentha kwa chilengedwe: 25 ± 5 ℃

Chinyezi: 25 ~ 75% RH

Fufuzani chinthu

(1) Tanthauzo la zolakwika zomwe zimayambitsidwa ndi magawo amkati.

a) Mawanga owala: madontho owala, osasintha nthawi zonse amawonekera pa LCD pansi pa mtundu wakuda.

b) Madontho akuda: Muzithunzi zoyera, zobiriwira, ndi buluu, madontho akuda okhala ndi kukula komweko amawonekera pa LCD.

c) 2 mfundo pafupi = 1 peya = 2 mfundo.

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.
