Ukucaciswa Kokuhlola

injongo

Qinisekisa ukuthi imikhiqizo yenkampani ihlangabezana nezidingo zamakhasimende, inikezela ngesisekelo sokuhlolwa komkhiqizo, futhi iqinisekise ikhwalithi yomkhiqizo.

Ububanzi besicelo

Leli zinga lisebenza kuyo yonke imikhiqizo yemodyuli ye-TFT ekhiqizwa yi-XX.

Izinsiza Zokuhlola

Umshini wokulinganisa kagesi, isibonisi sokuhlola, ingilazi yokukhulisa, isibani se-fluorescent, i-vernier caliper

Uhlelo lokusampula kanye nokuhlola izimo zemvelo

Iyunithi yokukhiqiza (noma inqubo ye-QC) yenza ukuhlolwa okugcwele kokuhlolwa kokubukeka nokuhlolwa kokusebenza kukagesi, kanye nokukalwa kosayizi noma ukuhlolwa okukhethekile, isiqeshana sokuqala semodeli ngayinye sithathwa futhi sahlolwa ama-5pcs.

Iyunithi yekhwalithi ilinganisa ama-5pcs esampula yokuqala yemodeli ngayinye, futhi isebenzisa i-GB / —2012 yokuhlola okujwayelekile isampula lesikhathi esisodwa sokuhlolwa kokubukeka, futhi izinga lokuhlola jikelele yi-II.

Izinga elingafanelekile Ileveli evumelekile (AQL) Ukuhlolwa okujwayelekile kwekhwalithi efanelekile
Ukushoda okuyinhloko   Uma usayizi unephutha, 0 thola ukubuya okungu-1

okuphelele

Umhloli udinga ukugqoka indandatho ye-electrostatic namakhothi weminwe ayisishiyagalombili ezandleni zombili.Uma kuyi-LCD ngaphandle kwe-polarizer enamathiselwe, yonke iminwe kufanele ifake imibhede yomunwe.

Umhloli angabheka ngokubukeka noma aqhathanise netafula lokuqhathanisa ifilimu.

Sicela ubheke isampula esivivinyweni sikagesi usebenzisa isibonisi sokuhlola nesikrini sokubonisa.

Ibanga phakathi kwamehlo omhloli nomkhiqizo lingama-30 ~ 40 cm. I-engeli yokubuka yokuhlola ingama- ± 15 degrees ebusweni bangaphambili bephaneli yokubonisa mpo kanye nama- ± 45 degrees ngaphambili kobuso bephaneli yokubonisa enezingqimba (bona isithombe esingezansi)

a) Izindawo ezigqamile: amachashazi akhanyayo, angosayizi oqhubekayo avela ku-LCD ngaphansi kwephethini elimnyama.

b) Amachashazi amnyama: ezithombeni ezihlanzekile ezibomvu, eziluhlaza, neziluhlaza okwesibhakabhaka, amachashazi amnyama anosayizi ofanayo avela ku-LCD.

c) Amaphuzu ama-2 aseduze = i-1 pair = 2 amaphuzu.
