Sònrachadh deuchainn

adhbhar

Dèan cinnteach gu bheil toraidhean a ’chompanaidh a’ coinneachadh ri riatanasan luchd-cleachdaidh, a ’toirt seachad bunait airson sgrùdadh toraidh, agus a’ dèanamh cinnteach à càileachd toraidh.

Farsaingeachd an tagraidh

Tha an inbhe seo a ’buntainn ris a h-uile toradh modal TFT a chaidh a dhèanamh le XX.

Uidheam deuchainn

Inneal tomhais dealain, tàmh-àirneis deuchainn, glainne meudachaidh, lampa flùraiseach, vernier caliper

Plana samplachaidh agus sgrùdadh suidheachadh na h-àrainneachd

Bidh an aonad saothrachaidh (no pròiseas QC) a ’dèanamh làn sgrùdadh airson sgrùdadh coltas agus deuchainn coileanaidh dealain, agus airson tomhas meud no sgrùdadh sònraichte, tha a’ chiad phìos de gach modail air a samplachadh agus air a dhearbhadh 5pcs.

Tha an aonad càileachd a ’tomhas 5pcs airson a’ chiad sampall de gach modail, agus a ’gabhail ri plana samplachaidh aon-ùine sgrùdadh àbhaisteach GB / —2012 airson sgrùdadh coltas, agus is e an ìre sgrùdaidh coitcheann II.

iomlan

Feumaidh an neach-sgrùdaidh fàinne electrostatach agus ochd cotan meòir a chaitheamh air an dà làmh. Mas e LCD a th ’ann às aonais polarizer ceangailte, bu chòir còtaichean meòir a bhith air gach corrag.

Faodaidh an neach-sgrùdaidh sgrùdadh lèirsinneach a dhèanamh no coimeas a dhèanamh ris a ’chlàr coimeas film.

Feuch an toir thu sùil air an sampall airson an deuchainn dealain a ’cleachdadh tàmh-àirneis deuchainn agus scrion taisbeanaidh.

Is e an astar eadar sùilean an neach-sgrùdaidh agus an toradh 30 ~ 40 cm. Tha an ceàrn seallaidh sgrùdaidh ± 15 ceum air uachdar aghaidh a ’phannail taisbeanaidh dìreach agus ± 45 ceum air uachdar aghaidh a’ phannal taisbeanaidh chòmhnard (faic am figear gu h-ìosal)

Solas àrainneachd: 800 ~ 1200LUX airson sgrùdadh lèirsinneach

Teòthachd na h-àrainneachd: 25 ± 5 ℃

Taiseachd: 25 ~ 75% RH

Thoir sùil air cuspair

(1) Mìneachadh air lochdan puing air adhbhrachadh le pannalan a-staigh.

a) Spotan soilleir: nochdaidh dotagan soilleir, seasmhach air an LCD fon phàtran dubh.

b) dotagan dorcha: Anns na dealbhan fìor dearg, uaine agus gorm, tha dotagan dorcha leis an aon mheud a ’nochdadh air an LCD.

c) 2 phuing ri taobh = 1 paidhir = 2 phuing.
