YONGS Electronic Technology Co., Ltd., kumpanija professjonali tal-wiri LED, it-tfaċċar tal-wiri LED għamlitha aktar u aktar konvenjenti għan-nies biex jiksbu informazzjoni, u żiedet ukoll aktar kanali għar-reklamar u t-tixrid tal-informazzjoni. ġabu bidliet ta'-earthing. Madankollu, sibna li l-iskrin tal-wiri LED spiss ikollu din it-tip ta 'problema fil-proċess ta' applikazzjoni, jiġifieri, l-iskrin tal-wiri jista 'jaħdem normalment fil-bidu tal-użu, iżda wara perjodu ta' użu, l-iskrin se jidher dawl baxx, teptip , falliment, Luminożità intermittenti u fenomeni oħra se jġibu ħsara serja lill-prodott. Hemm ħafna raġunijiet għal dan il-fenomenu. Illum, ser niffoka fuq li nispjega wieħed mill-aktar fatturi importanti, li huwa l-proċess ta 'tixjiħ tal-iskrin tal-wiri.
First of all, aging is an important guarantee for the reliability of LED electronic display products, and it is also a procedure that must be followed after each display is completed. If there is no aging display, whether it is indoor, outdoor or monochrome, two-color and full-color , are substandard products. And LED products can improve performance after aging, and help to stabilize the performance in later use. The aging test is a very important link in product quality control, but it is often ignored in many cases, and it is impossible to carry out correct and effective aging. LED aging test is a countermeasure taken according to the characteristics of the product's failure rate curve, that is, the bathtub curve, so as to improve the reliability of the product.
It-tieni nett, il-metodi tat-tixjiħ LED jinkludu tixjiħ kostanti tal-kurrent u tixjiħ kostanti tal-vultaġġ.
1. Constant current source means that the current is constant at any time. If there is a frequency problem, it is not a constant current. That's AC or pulsating current. The AC or pulsating current source can be designed to have a constant RMS value, but this kind of power source cannot be called a constant current source. Constant current aging is the most suitable LED current working characteristic and the most scientific LED aging method;
2. It-tixjiħ tal-impatt tal-kurrent żejjed huwa wkoll metodu ġdid ta 'tixjiħ adottat mill-manifatturi. Bl-użu ta 'sors ta' kurrent kostanti bi frekwenza aġġustabbli u kurrent aġġustabbli għal tali tixjiħ, il-kwalità u l-istennija tal-ħajja tal-LED jistgħu jiġu ġġudikati fi żmien qasir, u jistgħu jintgħażlu. Hemm ħafna perikli moħbija li ma jistgħux jiġu esklużi mit-tixjiħ konvenzjonali.
Fl-aħħarnett, l-affarijiet li għandek tagħti attenzjoni waqt it-test tal-ħruq-in huma kif ġej:
1. Il-ħin tat-test tal-iskrin tal-wiri mhuwiex inqas minn 48 siegħa.
2. It-test tat-tixjiħ tal-wiri tal-iskrin LED kbir-għandu jattendi xi ħadd fuq ix-xogħol. Jekk jinstabu xi problemi, għandhom jiġu rrappurtati lill-maniġer tal-inġinerija għall-ipproċessar.
3. It-test tal-gradjent monokromatiku u fuq skala griża m'għandux ikun inqas minn 48 siegħa.
4. It-test tal-effett tal-vidjo u tat-test m'għandux ikun inqas minn 48 siegħa.
5. Kontenut tat-test: skrin abjad, aħmar, aħdar, blu, monokromu, gradjent fuq skala griża, effett tal-vidjo, effett tat-test.
