Namhlanje, ii-LED zisetyenziswa ngokubanzi, kodwa i-diode yokuqala ekhupha ukukhanya yaqanjwa ngaphezu kweminyaka engama-50 edlulileyo ngumsebenzi woMbane Jikelele. Ukukwazi kwee-LED kwabonakala ngokukhawuleza, njengoko zincinci, zihlala ziqinile kwaye zikhanya. Ii-LED nazo zasebenzisa amandla amancinci kunee-incandescent bulbs. Ukutyhubela iminyaka, itekhnoloji ye-LED yenze amanyathelo abalulekileyo. Kwiminyaka elishumi edlulileyo, i-high-resolution enkuluIziboniso ze-LEDziye zasetyenziswa kumabala emidlalo, kusasazo lukamabonakude, kwiindawo zikawonke wonke, nanjengeebhakana ezikhanyayo eLas Vegas naseTimes Square.
Iinguqu ezintathu ezinkulu ziphembelele iziboniso ze-LED zanamhlanje: isisombululo esiphuculweyo, ukukhanya okwandisiweyo, kunye nokuguquguquka okusekwe kwisicelo. Makhe sihlolisise nganye ngokweenkcukacha.
ISigqibo esomeleziweyo
Imboni yokubonisa i-LED isebenzisa i-pixel pitch njengomlinganiselo oqhelekileyo wokubonisa isisombululo semiboniso yedijithali. Ukuphakama kwePixel ngumgama ukusuka kwipixel enye (iqela le-LED) ukuya kwipixel elandelayo ecaleni, ngaphezulu, okanye ngaphantsi kwayo. Iipixel ezincinci zicinezela isithuba, zivumela isisombululo esiphezulu. Iziboniso ze-LED zakuqala zazisebenzisa iiglowubhu ezinesombululo esisezantsi ezinokusebenza kuphela ngokubhaliweyo. Nangona kunjalo, ngokufika kobuchwephesha obutsha be-LED, ngoku kunokwenzeka ukuba kungekuphela nje umbhalo kodwa kunye nemifanekiso, oopopayi, iiklip zevidiyo kunye nolunye ulwazi. Namhlanje, imiboniso ye-4K ene-pixel count ye-4,096 ikhawuleza ibe ngumgangatho. Izigqibo eziphezulu, ezifana ne-8K, zinokwenzeka, nangona zincinci.
Ukwandiswa kokuKhanya
Amaqela e-LED enza iziboniso ze-LED zihambele phambili kakhulu. Kule mihla, ii-LED zinokukhupha ukukhanya okuqaqambileyo, okucacileyo kwizigidi zemibala. Ezi pixels okanye diode, xa zidityanisiwe, zinokudala iziboniso ezinomtsalane ezinokubonwa kwii-engile ezibanzi. Ii-LED ngoku zibonelela ngemigangatho ephezulu yokuqaqamba kwalo naluphi na uhlobo lokubonisa. Le mveliso iqaqambileyo ivumela izikrini ukuba zikhuphisane nokukhanya kwelanga ngqo-inzuzo enkulu kwimiboniso yangaphandle kunye nevenkile yangaphambili.
Ukuguquguquka kokusetyenziswa kwe-LED
Ukutyhubela iminyaka, iinjineli zisebenzele ukugqibelela ukubekwa kwezixhobo zombane ngaphandle. Iziboniso ze-LED kufuneka zimelane nemingeni yendalo, kubandakanywa ukuguquguquka kweqondo lokushisa kwiimozulu ezininzi, amanqanaba ahlukeneyo okufuma, kunye nomoya onetyuwa kwiindawo eziselunxwemeni. Iziboniso ze-LED zanamhlanje zithembeke kakhulu kwindawo yangaphakathi nangaphandle, zibonelela ngamathuba amaninzi entengiso kunye nokusasazwa kolwazi.
Iipropati ezingezizo ilitha zeIzikrini ze-LEDbenze ukhetho olukhethwayo kwiisethingi ezahlukeneyo, kubandakanya usasazo, ukuthengisa, kunye nemidlalo.
Ngelixa elizayo
Iziboniso zeDijithali ze-LEDzitshintshe kakhulu ekuhambeni kweminyaka. Izikrini ziye zaba zikhulu, zincinci, kwaye ziza kwiimilo ezahlukeneyo kunye nobukhulu. Imiboniso ye-LED yexesha elizayo iya kubandakanya ubukrelekrele bokwenziwa, ukwandisa ukusebenzisana, kunye nokubonelela ngeendlela zokuzisebenzela. Ukongeza, i-pixel pitch iya kuqhubeka iyancipha, ivumela ukuyilwa kwezikrini ezikhulu kakhulu ezinokujongwa ngokusondeleyo ngaphandle kokuncama isisombululo.
I-Hot Electronics ithengisa uluhlu olubanzi lweziboniso ze-LED. Yasekwa ngo-2003, iHot Electronics nguvulindlela ophumelele ibhaso kwimiqondiso yedijithali kwaye uye wakhawuleza waba yenye yabathengisi be-LED abakhula ngokukhawuleza elizweni, ababoneleli berenti, kunye nabahlanganisi. I-Hot Electronics iphakamisa ubuhlakani obucwangcisiweyo ukwenza izisombululo ezintsha kwaye ihlala igxile kubathengi ukuhambisa awona mava abalaseleyo e-LED.
