Namuhla, ama-LED asetshenziswa kabanzi, kodwa i-diode yokuqala ekhipha ukukhanya yasungulwa eminyakeni engaphezu kwengu-50 edlule ngumsebenzi wakwaGeneral Electric. Amandla ama-LED abonakala ngokushesha, njengoba ayemancane, ehlala isikhathi eside, futhi ekhanyayo. Ama-LED nawo asebenzise amandla amancane kunama-incandescent bulb. Ngokuhamba kweminyaka, ubuchwepheshe be-LED buye benza intuthuko enkulu. Eminyakeni eyishumi edlule, ukulungiswa okuphezulu okukhuluIzibonisi ze-LEDasetshenziswe ezinkundleni zemidlalo, ekusakazweni kukamabonakude, ezindaweni zomphakathi, nanjengamabhakabhaka akhanyayo e-Las Vegas nase-Times Square.
Izinguquko ezintathu ezinkulu zibe nomthelela ekuboniseni kwesimanje kwe-LED: ukulungiswa okuthuthukisiwe, ukukhanya okukhuphukile, nokusebenzisana okusekelwe kuhlelo lokusebenza. Ake sihlole ngayinye ngokuningiliziwe.
Ukulungiswa Okuthuthukisiwe
Imboni yokubonisa i-LED isebenzisa ukuphakama kwephikseli njengesilinganiso esijwayelekile ukukhombisa ukulungiswa kwezibonisi zedijithali. Ukuphakama kwe-Pixel ibanga ukusuka kuphikseli eyodwa (iqoqo le-LED) ukuya kuphikseli elandelayo eduze, ngaphezulu, noma ngaphansi kwayo. Amaphikseli amancane acindezela isikhala, okuvumela ukulungiswa okuphezulu. Izibonisi ze-LED zakuqala zazisebenzisa ama-bulb anokulungiswa okuphansi okungakhiqiza umbhalo kuphela. Nokho, ngokufika kobuchwepheshe obusha be-LED obuphezulu, manje sekungenzeka ukuthi ungagcini nje ngokuveza umbhalo kodwa nezithombe, izithombe ezinyakazayo, iziqeshana zevidiyo, nolunye ulwazi. Namuhla, izibonisi ze-4K ezinenani lamaphikseli avundlile angu-4,096 ziba izinga ngokushesha. Ngisho nezinqumo eziphakeme, njenge-8K, zingenzeka, nakuba zingavamile.
Ukugqama Kwandisiwe
Amaqoqo e-LED akha izibonisi ze-LED athuthuke kakhulu. Namuhla, ama-LED angakhipha ukukhanya okukhanyayo, okucacile ngezigidi zemibala. Lawa maphikseli noma ama-diode, uma ehlangene, angakha izibonisi ezikhangayo ezibukeka ngama-engeli abanzi. Ama-LED manje anikezela ngamaleveli okukhanya aphakeme kakhulu anoma yiluphi uhlobo lwesibonisi. Lokhu okukhiphayo okugqamile kuvumela izikrini ukuthi ziqhudelane nokukhanya kwelanga okuqondile—inzuzo enkulu yezibonisi zangaphandle nangaphambili kwesitolo.
Ukuhlukahluka kokusetshenziswa kwe-LED
Ngokuhamba kweminyaka, onjiniyela baye basebenza ukwenza kahle ukubekwa kwemishini kagesi ngaphandle. Izibonisi ze-LED zidinga ukumelana nezinselele zemvelo, okuhlanganisa ukushintshashintsha kwezinga lokushisa ezimweni eziningi zezulu, amazinga womswakamo ahlukahlukene, nomoya onosawoti ezindaweni ezisogwini. Izibonisi ze-LED zanamuhla zithembeke kakhulu kuzo zombili izindawo ezingaphakathi nangaphandle, zinikeza amathuba amaningi okukhangisa nokusabalalisa ulwazi.
Izakhiwo ezingabenyezi zeIzikrini ze-LEDzizenze zibe yinketho ekhethwayo yezilungiselelo ezihlukahlukene, ezihlanganisa ukusakaza, ukuthengisa, nemicimbi yezemidlalo.
Ikusasa
Izibonisi ze-Digital LEDziye zashintsha kakhulu phakathi neminyaka. Izikrini sezikhudlwana, zizacile, futhi ziza ngezinhlobo nosayizi abahlukahlukene. Izibonisi ze-LED zesikhathi esizayo zizohlanganisa ubuhlakani bokwenziwa, ukukhulisa ukusebenzisana, ngisho nokuhlinzeka ngezinketho zokuzisiza. Ukwengeza, ukuphakama kwephikseli kuzoqhubeka nokuncipha, okuvumela ukudalwa kwezikrini ezinkulu kakhulu ezingabukelwa eduze ngaphandle kokudela ukulungiswa.
I-Hot Electronics ithengisa izinhlobonhlobo zezibonisi ze-LED. Isungulwe ngo-2003, i-Hot Electronics iyingqalabutho eyawina umklomelo kuzimpawu zedijithali ezisha futhi isibe ngomunye wabasabalalisi bezokuthengisa be-LED abakhula ngokushesha ezweni, abahlinzeki bokuqasha, nabahlanganisi. I-Hot Electronics isebenzisa ubudlelwano bamasu ukuze idale izixazululo ezintsha futhi ihlale igxile kumakhasimende ukuze ilethe ulwazi olungcono kakhulu lwe-LED.
