Posankha chowonetsera chatsopano, kaya cha kanema wawayilesi, chowunikira, kapena chikwangwani cha digito, chimodzi mwazovuta zomwe zimachitika kwambiri ndikusankha pakati paukadaulo wa LED ndi LCD. Mawu onsewa nthawi zambiri amakumana nawo muukadaulo, koma amatanthauza chiyani? Kumvetsetsa kusiyana pakati pa LED ndi LCD kungakuthandizeni kusankha mwanzeru kuti ndi teknoloji iti yowonetsera yomwe ingagwirizane ndi zosowa zanu.
Kumvetsetsa LED ndi LCD Technologies
Poyamba, ndikofunikira kumveketsa bwino kuti "LED" (Light Emitting Diode) ndi "LCD" (Liquid Crystal Display) siukadaulo wosiyana. Ndipotu nthawi zambiri amagwira ntchito limodzi. Umu ndi momwe:
- LCD: Chiwonetsero cha LCD chimagwiritsa ntchito makhiristo amadzimadzi kuwongolera kuwala ndikupanga zithunzi pazenera. Komabe, makristalowa samatulutsa kuwala paokha. M'malo mwake, amafunikira chowunikira chakumbuyo kuti chiwunikire chiwonetserocho.
- LED: Kuwala kwa LED kumatanthawuza mtundu wa kuunikiranso komwe kumagwiritsidwa ntchito pazowonetsa za LCD. Ma LCD achikhalidwe amagwiritsa ntchito CCFL (nyale zozizira za cathode fluorescent) powunikiranso, pomwe zowonetsera za LED zimagwiritsa ntchito ma diode otulutsa kuwala. Kuwunikira kwa LED uku ndi komwe kumapereka ma LED kuwonetsa dzina lawo.
Kwenikweni, "chiwonetsero cha LED" kwenikweni ndi "LED-backlit LCD display." Kusiyanitsa kuli mu mtundu wa backlighting ntchito.
Kusiyana Kwakukulu Pakati pa LED ndi LCD
- Backlighting Technology:
- LCD (CCFL backlighting): M'mbuyomu ma LCD ankagwiritsa ntchito ma CCFL, omwe amapereka kuwala kofanana pawindo lonse koma anali opanda mphamvu komanso ochulukirapo.
- LED (LED backlighting): Ma LCD amakono okhala ndi kuyatsa kwa LED amapereka zowunikira zambiri zakumalo, kupangitsa kusiyanitsa kwabwinoko komanso kuwongolera mphamvu. Ma LED amatha kukonzedwa mowoneka bwino m'mphepete kapena mosiyanasiyana, zomwe zimapangitsa kuti pakhale kuwongolera bwino pakuwala.
- Chithunzi Quality:
- LCD: Ma LCD a Standard CCFL-backlit amapereka kuwala koyenera koma nthawi zambiri amavutika ndi zakuda zakuya komanso kusiyana kwakukulu chifukwa cha kuchepa kwa kuyatsa kumbuyo.
- LED: Mawonekedwe a LED-backlit amapereka kusiyanitsa kwapamwamba, zakuda zakuya, ndi mitundu yowoneka bwino, chifukwa cha kutha kwa mdima kapena kuwunikira madera ena a zenera (njira yotchedwa dimming local).
- Mphamvu Mwachangu:
- LCD: Zowonetsera za CCFL-backlit zimadya mphamvu zambiri chifukwa cha kuwala kwawo kosagwira ntchito komanso kulephera kusintha kuwala kwamphamvu.
- LED: Zowonetsera za LED ndizopatsa mphamvu zambiri, chifukwa zimagwiritsa ntchito mphamvu zochepa ndipo zimatha kusintha kuwala kutengera zomwe zikuwonetsedwa.
- Slimmer Design:
- LCD: Ma LCD achikhalidwe a CCFL-backlit ndi ochulukirapo chifukwa cha machubu akulu owunikira.
- LED: Kukula kophatikizika kwa ma LED kumapangitsa mawonedwe ocheperako, opepuka, kuwapangitsa kukhala abwino kwa mapangidwe amakono, owoneka bwino.
- Kulondola Kwamtundu Ndi Kuwala:
- LCD: Zowonetsera za CCFL-backlit nthawi zambiri zimapereka kulondola kwamitundu koma zimatha kulephera kupereka zithunzi zowala komanso zowoneka bwino.
- LED: Zowonetsa za LED zimapambana kulondola kwamitundu komanso kuwala, makamaka zomwe zili ndi ukadaulo wapamwamba ngati madontho a quantum kapena zowunikira zonse.
- Utali wamoyo:
- LCD: Zowonetsera za CCFL-backlit zimakhala ndi moyo wamfupi chifukwa cha kuchepa kwapang'onopang'ono kwa machubu a fulorosenti pakapita nthawi.
- LED: Zowonetsera za LED-backlit zimakhala ndi moyo wautali, popeza ma LED ndi olimba kwambiri ndipo amasunga kuwala kwawo kwa nthawi yaitali.
Mapulogalamu ndi Kuyenerera
- Zosangalatsa Zanyumba: Kwa iwo omwe akufuna zithunzi zapamwamba zokhala ndi mitundu yolemera komanso zosiyana kwambiri, zowonetsera za LED-backlit ndizosankha zomwe amakonda. Amagwiritsidwa ntchito kwambiri m'makanema amakono ndi zowunikira, zomwe zimapereka mwayi wowonera makanema, masewera, komanso kutsatsa.
- Kugwiritsa Ntchito Mwaukadaulo: M'malo omwe kulondola kwamtundu ndi kuwala ndikofunikira, monga momwe zojambulajambula, kusinthira makanema, ndi zikwangwani zama digito, zowonetsera za LED zimapereka kulondola komanso kumveka bwino komwe kumafunikira.
- Zosankha Zothandizira Bajeti: Ngati mtengo ndiwodetsa nkhawa kwambiri, zowonetsera zachikhalidwe za CCFL-backlit LCD zitha kupezekabe pamitengo yotsika, ngakhale magwiridwe ake sangafanane ndi amitundu ya LED-backlit.
Kutsiliza: Chabwino n'chiti?
Kusankha pakati pa LED ndi LCD kumadalira kwambiri zomwe mumazikonda kwambiri pachiwonetsero. Ngati mumayika patsogolo chithunzithunzi chapamwamba, mphamvu zogwiritsira ntchito mphamvu, ndi mapangidwe amakono, chiwonetsero cha LED-backlit ndicho chopambana. Zowonetsa izi zimapereka zabwino kwambiri padziko lonse lapansi: magwiridwe antchito odalirika aukadaulo wa LCD kuphatikiza zabwino za kuyatsa kwa LED.
Komabe, ngati muli ndi bajeti yolimba kapena muli ndi zofunikira zenizeni zomwe sizikufuna ukadaulo waposachedwa, LCD yakale yokhala ndi CCFL yowunikira kumbuyo ikhoza kukhala yokwanira. Izi zati, ukadaulo ukupita patsogolo, zowonetsera za LED zakhala zopezeka mosavuta komanso zotsika mtengo, zomwe zimawapangitsa kukhala njira yopitira kwa ogula ndi akatswiri ambiri.
Pankhondo ya LED vs. LCD, wopambana weniweni ndi wowonera, yemwe amapindula ndi zochitika zowoneka bwino zomwe zimayendetsedwa ndi matekinoloje atsopano owonetsera.
