Ngophuhliso olukhawulezayo lwetekhnoloji yokubonisa ye-LED, iimveliso zokubonisa ze-LED zibonisa uphuhliso olwahlukeneyo. Izikrini zemiboniso zangoku ze-LED zisetyenziswa ngokubanzi kumashishini ahlukeneyo. Nangona kunjalo, kubaqalayo, amagama amaninzi obuchwephesha abonisa i-LED asetyenziswa. Andazi, ke ngawaphi amagama aqhelekileyo obuchwephesha kwimiboniso ye-LED?
Ukukhanya kwe-LED: Ukuqaqamba kwediode ekhupha ukukhanya kubonakaliswa ngokubanzi kukukhanya okuKhanyayo kwiiyunithi zeCandela cd; I-1000ucd (encinci-candela) = 1 mcd (induli candela), 1000mcd = 1 cd. Ubungakanani bokukhanya kwe-LED enye yokusetyenziswa kwangaphakathi ngokubanzi yi-500ucd-50 mcd, ngelixa ukukhanya kokukhanya kwe-LED enye yokusetyenziswa kwangaphandle kufanele kube yi-100 mcd-1000 mcd okanye i-1000 mcd okanye nangaphezulu.
Imodyuli ye-pixel ye-LED: Ii-LEDs zilungiswe kwimatrix okanye kwinxalenye yepen, kwaye zikhethwe kwiimodyuli ezinobungakanani obuqhelekileyo. Umboniso wasendlwini oqhele ukusetyenziswa kwimodyuli ye-pixel eyi-8, 8 yamagama ayi-7 icandelo leemodyuli zedijithali. Imodyuli ye-pixel yokubonisa yangaphandle ineenkcukacha ezinje nge-4 * 4, 8 * 8, 8 * 16 pixels. Imodyuli ye-pixel yesikrini somboniso sangaphandle sikwabhekiswa njengesihloko semodyuli yentloko kuba ipikseli nganye inezinto ezimbini okanye nangaphezulu zeetyhubhu ze-LED.
IPixel kunye nePixel Ububanzi: Iyunithi nganye yokukhanyisa ukukhanya kwe-LED (ichaphaza) enokulawulwa ngokukodwa kumboniso we-LED ibizwa ngokuba yi-pixel (okanye ipikseli). Ububanzi bepikseli ∮ bubhekisa kububanzi bepikseli nganye ngeemilimitha.
Resolution: Inani lemiqolo kunye neekholamu ze-pixels zokubonisa ze-LED zibizwa ngokuba sisisombululo sesiboniso se-LED. Isisombululo linani elipheleleyo leepekseli kwisiboniso, esimisela ulwazi kulwazi lomboniso.
Isilinganisi esingwevu: Isikali esingwevu sibhekisa kwinqanaba apho ukukhanya kwe-pixel kutshintsha. Isikali esingwevu sombala oyintloko ngokubanzi sinamanqanaba asi-8 ukuya kweli-12. Umzekelo, ukuba inqanaba elingwevu lombala ngamnye ophambili ngamanqanaba angama-256, kwimbala emibini yesikrini sombala wokuqala, umbala obonisiweyo ngu-256 × 256 = 64K umbala, okwabizwa ngokuba sisikrini sombala esingu-256.
Imibala emibini ephambili: Uninzi lwemibala ebonakalayo ye-LED namhlanje ziiscreen zemibala emibini, oko kukuthi, ipikseli nganye ine-LED ezimbini eziswelekileyo: enye yeyokufa okubomvu enye kukufa okuluhlaza. I-pixel ibomvu xa i-red die ikhanyisiwe, i-green iba luhlaza xa i-green die ikhanyisiwe, kwaye i-pixel yona imthubi xa i-red kunye ne-green dies is ngaxeshanye zikhanyisiwe. Phakathi kwazo, obomvu nohlaza kuthiwa yimibala ephambili.
Umbala opheleleyo: umbala obomvu nohlaza ophindwe kabini kunye nomibala eluhlaza okwesibhakabhaka, imibala emithathu ephambili yembala epheleleyo. Ukusukela ukuba itekhnoloji yokwenza imibala egcweleyo ngombala kunye nokufa okuluhlaza okusulungekileyo sele ikhulile, intengiso yimibala epheleleyo.
I-SMT kunye ne-SMD: I-SMT bubuchwephesha bokuphakama komhlaba (bufutshane be-Surface Mounted Technology), okwangoku yeyona teknoloji ithandwayo kunye nenkqubo kwishishini lendibano ye-elektroniki; I-SMD sisixhobo esonyusa umphezulu womhlaba (mfutshane ngesixhobo esinyuswe umphezulu)
