A yau,mamaye matsayi mai mahimmanci a fagen talla da abubuwan waje. Dangane da buƙatun kowane aikin, kamar zaɓin pixels, ƙuduri, farashi, abun ciki na sake kunnawa, rayuwar nuni, da kiyaye gaba ko baya, za a sami ɓangarorin ciniki daban-daban.
Tabbas, ƙarfin ɗaukar nauyi na wurin shigarwa, haske a kusa da wurin shigarwa, nisan kallo da kusurwar kallo, yanayi da yanayin yanayin wurin shigarwa, ko mai hana ruwa ne, ko yana da iska da kuma iska. bacewa, da sauran yanayi na waje. Don haka yadda ake siyan nunin LED na waje?
1, The need to display the content. An ƙayyade rabon fuskar difloma na hoto bisa ga ainihin abun ciki. Allon bidiyo shine gabaɗaya 4:3 ko 4:3 mafi kusa, kuma madaidaicin rabo shine 16:9.
2. Tabbatar da nisan kallo da kusurwar kallo. Domin tabbatar da hangen nesa mai nisa a yanayin haske mai ƙarfi, dole ne a zaɓi diodes masu fitar da haske mai tsananin haske.
3. Zane-zane na bayyanar da siffar sun sami damar tsara nunin LED bisa ga tsarin taron da siffar ginin. For example, in the 2008 Olympic Games and the Spring Festival Gala, the LED display technology was applied to the extreme to achieve extreme perfection visual effects.
4. Wajibi ne a kula da lafiyar wuta na wurin shigarwa, ka'idodin ceton makamashi na aikin, da dai sauransu Lokacin zabar, ingancin allon LED, da sabis na tallace-tallace na samfurin duk mahimman dalilai ne. to be considered. Ana shigar da allon nunin LED a waje, galibi ana fallasa shi ga rana da ruwan sama, kuma yanayin aiki yana da tsauri. Jika ko tsananin damshin kayan lantarki na iya haifar da gajeriyar kewayawa ko ma wuta, haifar da gazawa ko ma wuta, haifar da asara. Therefore, the requirement on the LED cabinet is to take into account the weather conditions, and be able to protect against wind, rain, and lightning.

Shigar da kayan aikin samun iska don kwantar da hankali, saboda zafin ciki na allon LED yana tsakanin -10 ℃ ~ 40 ℃. An shigar da fan na axial flow fan a bayan allon, wanda zai iya fitar da zafi lokacin da zafin jiki ya yi yawa.
6. Cost control. Yin amfani da wutar lantarki na nunin LED abu ne wanda dole ne a yi la'akari da shi.
