Lapho ukhetha isibonisi esisha, noma ngabe okomabonakude, ukuqapha, noma izimpawu zedijithali, enye yezinkinga ezivame kakhulu ukunquma phakathi kobuchwepheshe be-LED ne-LCD. Womabili la magama avame ukuhlangana nawo emhlabeni wezobuchwepheshe, kodwa asho ukuthini ngempela? Ukuqonda umehluko phakathi kwe-LED ne-LCD kungakusiza wenze isinqumo unolwazi mayelana nokuthi ibuphi ubuchwepheshe bokubonisa obufanele izidingo zakho.
Ukuqonda i-LED ne-LCD Technologies
Ukuqala, kubalulekile ukucacisa ukuthi i-"LED" (Light Emitting Diode) kanye "ne-LCD" (I-Liquid Crystal Display) akubona ubuchwepheshe obuhluke ngokuphelele. Eqinisweni, bavame ukusebenza ndawonye. Nansi indlela:
- I-LCD: Isibonisi se-LCD sisebenzisa amakristalu awuketshezi ukulawula ukukhanya nokudala izithombe esikrinini. Nokho, lawa makristalu awakhiqizi ukukhanya ngokwawo. Esikhundleni salokho, zidinga ukukhanya okungemuva ukuze zikhanyise isibonisi.
- I-LED: I-LED ibhekisela ohlotsheni lokukhanyisa okungemuva okusetshenziswa kuzibonisi ze-LCD. Ama-LCD endabuko asebenzisa i-CCFL (amalambu abandayo e-cathode fluorescent) ekukhanyiseni emuva, kuyilapho izibonisi ze-LED zisebenzisa ama-diode akhipha ukukhanya. Lokhu kukhanyisa kwe-LED yikho okunikeza ama-LED ukubonisa igama lawo.
Empeleni, "i-LED display" empeleni "i-LED-backlit LCD display." Umehluko usenhlotsheni yokukhanyisa emuva esetshenzisiwe.
Umehluko Obalulekile Phakathi kwe-LED ne-LCD
- I-Backlighting Technology:
- I-LCD (CCFL backlighting): Ngaphambilini ama-LCD abesebenzisa ama-CCFL, ahlinzeka ngokukhanya okufanayo esikrinini sonke kodwa ayengonga amandla futhi emkhulu.
- I-LED (i-LED backlighting): Ama-LCD esimanje anokukhanya kwe-LED anikezela ngokukhanyisa okwengeziwe, okwenza umehluko ongcono nokusebenza kahle kwamandla. Ama-LED angahlelwa ngokukhanya onqenqemeni noma ekucushweni kohlelo olugcwele, okuvumela ukulawula okunembe kakhudlwana phezu kokukhanya.
- Ikhwalithi Yesithombe:
- I-LCD: Ama-LCD ajwayelekile e-CCFL-backlit anikezela ngokugqama okuhloniphekile kodwa avame ukulwa nokumnyama okujulile nokugqama okuphezulu ngenxa yemikhawulo yokukhanyisa ngemuva.
- I-LED: Izibonisi ze-LED-backlit zinikeza ukugqama okuphakeme, okumnyama okujulile, nemibala egqamile, sibonga ikhono lokufiphalisa noma lokukhanyisela izindawo ezithile zesikrini (inqubo eyaziwa ngokuthi ukufiphala kwendawo).
- Ukusebenza Kwamandla:
- I-LCD: Izibonisi ze-CCFL-backlit zisebenzisa amandla engeziwe ngenxa yokukhanya kwazo okunganele kanye nokungakwazi ukulungisa ukukhanya ngendlela eguqukayo.
- I-LED: Izibonisi ze-LED ziwonga kakhulu amandla, njengoba zisebenzisa amandla amancane futhi zingalungisa ukukhanya ngokuguquguqukayo ngokusekelwe kokuqukethwe okuboniswayo.
- I-Slimmer Design:
- I-LCD: Ama-LCD omdabu e-CCFL-backlit makhulu ngenxa yamashubhu amakhulu okukhanyisa ngemuva.
- I-LED: Usayizi ohlangene wama-LED uvumela izibonisi ezizacile, ezingasindi kakhudlwana, zizenze zilungele imiklamo yesimanjemanje, eshelelayo.
- Ukunemba Kombala Nokukhanya:
- I-LCD: Izibonisi ze-CCFL-backlit ngokuvamile zinikeza ukunemba okuhle kombala kodwa zingase zibe mfushane ekuletheni izithombe ezikhanyayo nezigqamile.
- I-LED: Izibonisi ze-LED zihamba phambili ngokunemba kombala nokukhanya, ikakhulukazi lezo ezinobuchwepheshe obuthuthukisiwe njengamachashazi e-quantum noma ukukhanya okungemuva okugcwele.
- Ubude bempilo:
- I-LCD: Izibonisi ze-CCFL-backlit zinesikhathi sokuphila esifushane ngenxa yokufiphala kancane kancane kwamashubhu e-fluorescent ngokuhamba kwesikhathi.
- I-LED: Izibonisi ze-LED-backlit zinesikhathi eside sempilo, njengoba ama-LED ahlala isikhathi eside futhi agcina ukukhanya kwawo isikhathi eside.
Izicelo Nokufaneleka
- Ukuzijabulisa Kwasekhaya: Kulabo abafuna ukubonwa kwekhwalithi ephezulu okunemibala ecebile nokuhluka okujulile, izibonisi ze-LED-backlit ziyinketho ekhethwayo. Asetshenziswa kakhulu komabonakude besimanje namamonitha, ahlinzeka ngolwazi olunzulu lokubuka amamuvi, amageyimu, nokusakaza.
- Ukusetshenziswa Professional: Ezimweni lapho ukunemba kombala nokukhanya kubalulekile, njengokuklanywa kwezithombe, ukuhlelwa kwevidiyo, nezimpawu zedijithali, izibonisi ze-LED zinikeza ukunemba nokucaca okudingekayo.
- Izinketho Ezivumelana Nesabelomali: Uma izindleko ziwukukhathazeka okuyinhloko, izibonisi ze-CCFL-backlit LCD zendabuko zisengatholwa ngamaphoyinti entengo aphansi, nakuba ukusebenza kwazo kungase kungafani nalokho kwamamodeli we-LED-backlit.
Isiphetho: Yikuphi Okungcono?
Ukukhetha phakathi kwe-LED ne-LCD kuncike kakhulu ekutheni yini oyithanda kakhulu kusibonisi. Uma ubeka phambili ikhwalithi yesithombe ephakeme kakhulu, ukonga amandla, kanye nedizayini yesimanjemanje, isibonisi se-LED-backlit singumnqobi ocacile. Lezi zibonisi zinikeza okuhle kakhulu kuyo yomibili imihlaba: ukusebenza okuthembekile kobuchwepheshe be-LCD kuhlanganiswe nezinzuzo zokukhanyisa kwe-LED.
Kodwa-ke, uma unesabelomali esiqinile noma unezidingo ezithile ezingadingi ubuchwepheshe bamuva nje, i-LCD endala enokukhanyisa kwe-CCFL ingase yanele. Lokho okushiwo, njengoba ubuchwepheshe buthuthuka, izibonisi ze-LED sezifinyeleleka kalula futhi zithengeka, okuzenza zibe inketho yokuya kubathengi abaningi kanye nochwepheshe ngokufanayo.
Empini ye-LED vs. LCD, owinile wangempela yisibukeli, ozuza ekuboneni okuhlala kuthuthuka okuqhutshwa ubuchwepheshe bokubonisa obusha.
