Xa ukhetha umboniso omtsha, nokuba kumabonakude, ukubeka iliso, okanye imiqondiso yedijithali, enye yezona ngxaki zixhaphakileyo kukwenza isigqibo phakathi kwe-LED kunye ne-LCD ubuchwepheshe. Omabini la magama ahlala edibana kwihlabathi letekhnoloji, kodwa athetha ukuthini ngokwenene? Ukuqonda umahluko phakathi kwe-LED kunye ne-LCD kunokukunceda wenze isigqibo esinolwazi malunga nokuba yeyiphi itekhnoloji yokubonisa eyilungele iimfuno zakho.
Ukuqonda i-LED kunye ne-LCD Technologies
Ukuqala, kubalulekile ukucacisa ukuba "i-LED" (i-Light Emitting Diode) kunye ne "LCD" (i-Liquid Crystal Display) ayizona iteknoloji ezihluke ngokupheleleyo. Enyanisweni, badla ngokusebenza kunye. Nantsi indlela:
- LCD: Umboniso weLCD usebenzisa iikristale ezingamanzi ukulawula ukukhanya kunye nokwenza imifanekiso kwiscreen. Nangona kunjalo, ezi kristale azivelisi ukukhanya ngokwazo. Endaweni yoko, bafuna isibane esingasemva ukukhanyisa umboniso.
- I-LED: I-LED ibhekisa kuhlobo lokukhanyisa umva olusetyenziswa kwiziboniso zeLCD. IiLCDs zemveli zisebenzisa iCCFL (izibane ezibandayo zecathode fluorescent) ukukhanyisa ngasemva, ngelixa iziboniso ze-LED zisebenzisa iidiode ezikhupha ukukhanya. Oku kukhanya kwe-LED koko kunika i-LED ukubonisa igama labo.
Enyanisweni, "i-LED display" ngokwenene "yi-LED-backlit LCD display." Umahluko ulele kuhlobo lwesibane esisemva esisetyenzisiweyo.
Umahluko ophambili phakathi kwe-LED kunye ne-LCD
- Itekhnoloji yokukhanyisa emva:
- LCD (CCFL backlighting): Ngaphambili ii-LCDs bezisebenzise ii-CCFL, ezibonelela ngokukhanya okufanayo kwiscreen kodwa zingasebenzi ngamandla kwaye zinkulu.
- Ukukhanya kwe-LED (ukukhanya kwe-LED): I-LCDs zanamhlanje ezine-LED backlighting zibonelela ngokukhanya kwendawo, okwenza umahluko ongcono kunye nokusebenza kakuhle kwamandla. Ii-LED zinokucwangciswa kwi-edge-lit okanye i-full-array configurations, evumela ulawulo oluchanekileyo phezu kokukhanya.
- Umgangatho Wemifanekiso:
- LCD: I-LCDs ezisemgangathweni ze-CCFL-backlit zinika ukukhanya okuhloniphekileyo kodwa zihlala zinzima kunye nobumnyama obunzulu kunye nokwahlukana okuphezulu ngenxa yokunciphisa ukukhanya.
- I-LED: Iziboniso ze-LED-backlit zibonelela ngokungafaniyo okuphezulu, ubumnyama obunzulu, kunye nemibala eqaqambileyo, ngenxa yokukwazi ukufiphaza okanye ukukhanyisa iindawo ezithile zesikrini (indlela eyaziwa ngokuba yi-dimming yendawo).
- Ukusebenza kakuhle kwamandla:
- LCD: Iziboniso ze-CCFL-backlit zisebenzisa amandla amaninzi ngenxa yokukhanya kwazo okuncinci kunye nokungakwazi ukulungelelanisa ukukhanya ngokuguquguqukayo.
- I-LED: Iziboniso ze-LED zinamandla ngakumbi, njengoko zisebenzisa amandla amancinci kwaye zinokuhlengahlengisa ukukhanya ngokuguquguqukayo ngokusekelwe kumxholo oboniswayo.
- Uyilo oluSlimmer:
- LCD: I-LCDs ze-CCFL zemveli ze-backlit zinkulu ngenxa yeetyhubhu ezinkulu zokukhanyisa.
- I-LED: Ubungakanani obubambeneyo bee-LED buvumela imiboniso emincinci, ekhaphukhaphu ngakumbi, ibenze ilungele uyilo lwangoku, oluthambileyo.
- Ukuchaneka koMbala kunye nokuKhanya:
- LCD: Iziboniso ze-CCFL-backlit ngokubanzi zibonelela ngokuchaneka kombala okuhle kodwa zinokuthi ziwe phantsi ekunikezeni imifanekiso eqaqambileyo nedlamkileyo.
- I-LED: Iziboniso ze-LED zigqwesa ngokuchaneka kombala kunye nokuqaqamba, ngakumbi ezo zinetekhnoloji ephucukileyo efana namachaphaza e-quantum okanye isibane esipheleleyo sasemva.
- Umsebenzi wobomi:
- LCD: Iziboniso ze-CCFL-backlit zinobomi obufutshane ngenxa yokuncipha kancinci kweetyhubhu ze-fluorescent ngokuhamba kwexesha.
- I-LED: Iziboniso ze-LED-backlit zinexesha elide lokuphila, njengoko ii-LED zihlala zihlala zihlala zihlala zihlala zihlala ixesha elide.
Izicelo kunye nokufaneleka
- Ulonwabo lwasekhaya: Kulabo bafuna izinto ezibonakalayo ezikumgangatho ophezulu kunye nemibala ecebileyo kunye nokwahlukana okunzulu, iziboniso ze-LED-backlit zikhethwa ngokukhethekileyo. Zisetyenziswa ngokubanzi koomabonakude banamhlanje kunye nababek' iliso, banikezela ngamava okubukela okuntywilayo kwiimuvi, imidlalo, kunye nokusasaza.
- Ukusetyenziswa kobuNgcali: Kwiindawo apho ukuchaneka kombala kunye nokukhanya kubalulekile, njengokuyilwa kwegraphic, ukuhlelwa kwevidiyo, kunye neempawu zedijithali, iziboniso ze-LED zibonelela ngokuchaneka kunye nokucaca okufunekayo.
- Iinketho ezilungele uhlahlo-lwabiwo-mali: Ukuba ixabiso liyinkxalabo ephambili, i-CCFL-backlit LCD yendabuko isenokufumaneka kumaxabiso aphantsi, nangona ukusebenza kwabo kungahambelani neemodeli ze-LED-backlit.
Ukuqukumbela: Yeyiphi Engcono?
Ukukhetha phakathi kwe-LED kunye ne-LCD ubukhulu becala kuxhomekeke kwinto oyixabisa kakhulu kumboniso. Ukuba ubeka phambili umgangatho womfanekiso ophezulu, ukusebenza kakuhle kwamandla, kunye noyilo lwangoku, umboniso we-LED-backlit uphumelele ngokucacileyo. Ezi ziboniso zibonelela ngezona zinto zibalaseleyo zehlabathi: ukusebenza okuthembekileyo kobuchwephesha beLCD kudityaniswe nenzuzo yokukhanya kwe-LED ngasemva.
Nangona kunjalo, ukuba unohlahlo lwabiwo-mali oluluqilima okanye uneemfuno ezithile ezingabange itekhnoloji yamva nje, i-LCD yakudala ene-CCFL ekhanyisela ngasemva inokwanela. Oko kwathiwa, njengoko itekhnoloji ihambela phambili, iziboniso ze-LED ziye zafikeleleka ngakumbi kwaye ziyafikeleleka, nto leyo eyenza ukuba ibe lukhetho lokuya kubathengi abaninzi kunye neengcali ngokufanayo.
Kwidabi le-LED vs. LCD, oyena mntu uphumeleleyo ngumbukeli, oxhamla kumava abonwayo ahlala ephucuka eqhutywa bubuchwepheshe bokubonisa obutsha.
