Mugihe uhisemo icyerekezo gishya, haba kuri tereviziyo, monitor, cyangwa ibimenyetso bya digitale, kimwe mubibazo bikunze kugaragara ni uguhitamo hagati ya tekinoroji ya LED na LCD. Aya magambo yombi akunze guhura nisi yikoranabuhanga, ariko mubyukuri asobanura iki? Gusobanukirwa itandukaniro riri hagati ya LED na LCD birashobora kugufasha gufata icyemezo cyuzuye kubijyanye nikoranabuhanga ryerekana rikwiranye nibyo ukeneye.
Gusobanukirwa Ikoranabuhanga rya LED na LCD
Gutangira, ni ngombwa gusobanura ko "LED" (Umucyo wohereza urumuri) na "LCD" (Liquid Crystal Display) ntabwo ari tekinoloji itandukanye rwose. Mubyukuri, akenshi bakorera hamwe. Dore uko:
- LCD: LCD yerekana ikoresha kristu yamazi kugirango igenzure urumuri no gukora amashusho kuri ecran. Ariko, kristu ntizitanga urumuri rwonyine. Ahubwo, bakeneye itara ryaka kugirango bamurikire ibyerekanwe.
- LED: LED bivuga ubwoko bwamatara akoreshwa muri LCD yerekana. LCD gakondo ikoresha CCFL (amatara akonje ya cathode fluorescent) kumurika, mugihe LED yerekana ikoresha diode itanga urumuri. Amatara ya LED niyo atanga LED yerekana izina ryabo.
Mubyukuri, "LED yerekana" mubyukuri "LED yerekana inyuma LCD." Itandukaniro riri muburyo bwo kumurika inyuma byakoreshejwe.
Itandukaniro ryingenzi hagati ya LED na LCD
- Kumurika Ikoranabuhanga:
- LCD (Amatara ya CCFL): Mbere LCDs yakoreshaga CCFLs, yatangaga urumuri rumwe kuri ecran ariko ntirukoreshe ingufu kandi nini.
- LED (LED yamurika): LCD igezweho ifite amatara ya LED itanga urumuri rwinshi, rushobora gutandukanya neza no gukoresha ingufu. LED irashobora gutondekwa muburyo bugaragara cyangwa bwuzuye-iboneza, bigufasha kugenzura neza urumuri.
- Ubwiza bw'ishusho:
- LCD.
- LED.
- Ingufu:
- LCD: CCFL-inyuma yerekana itwara imbaraga nyinshi kubera itara ryayo ridakorwa neza no kudashobora guhindura umucyo muburyo bwiza.
- LED: LED yerekanwa ikoresha ingufu nyinshi, kuko ikoresha imbaraga nke kandi irashobora guhindura umucyo mu buryo bushingiye kubirimo kwerekanwa.
- Igishushanyo mbonera:
- LCD: Gakondo CCFL-isubira inyuma LCDs nini cyane kubera imiyoboro minini yamurika.
- LED: Ingano yoroheje ya LED itanga uburyo bworoshye, bworoshye kwerekana, bigatuma biba byiza kubishushanyo mbonera bigezweho.
- Ibara neza kandi ryiza:
- LCD: CCFL-isubira inyuma yerekana muri rusange itanga amabara meza ariko irashobora kugabanuka mugutanga amashusho meza kandi meza.
- LED.
- Ubuzima:
- LCD: CCFL-yerekana inyuma ifite igihe gito cyo kubaho kubera kugabanuka gahoro gahoro ya fluorescent mugihe.
- LED: LED-inyuma yerekana ifite igihe kirekire cyo kubaho, kuko LED iraramba kandi ikagumana umucyo mugihe kirekire.
Porogaramu na Bikwiranye
- Imyidagaduro yo murugo: Kubashaka amashusho yujuje ubuziranenge afite amabara akungahaye kandi atandukanye cyane, LED-inyuma yerekana ni byo byatoranijwe. Zikoreshwa cyane muri tereviziyo zigezweho na monitor, zitanga uburambe bwo kureba kuri firime, gukina, no gutambuka.
- Gukoresha Umwuga: Mubidukikije aho ibara ryukuri nubucyo ari ngombwa, nko mubishushanyo mbonera, gutunganya amashusho, hamwe nibyapa bya digitale, LED yerekana itanga ibisobanuro kandi bisobanutse bikenewe.
- Amahitamo-Yinshuti: Niba ikiguzi aricyo kintu cyibanze, gakondo ya CCFL-isubira inyuma LCD yerekana irashobora kuboneka kubiciro biri hasi, nubwo imikorere yabo idashobora guhura niy'icyitegererezo cya LED-inyuma.
Umwanzuro: Niki Cyiza?
Guhitamo hagati ya LED na LCD ahanini biva kubyo uha agaciro cyane mubyerekanwa. Niba ushyize imbere ubuziranenge bwamashusho, ingufu zingirakamaro, hamwe nigishushanyo kigezweho, kwerekana LED-inyuma yerekana neza uwatsinze neza. Iyerekana itanga ibyiza byisi byombi: imikorere yizewe ya tekinoroji ya LCD hamwe nibyiza byo kumurika LED.
Ariko, niba uri kuri bije itagabanije cyangwa ufite ibisabwa byihariye bidasaba ikoranabuhanga rigezweho, LCD ishaje ifite amatara ya CCFL irashobora kuba ihagije. Ibyo byavuzwe, uko ikoranabuhanga rigenda ritera imbere, kwerekana LED byagaragaye cyane kandi bihendutse, bigatuma bajya guhitamo kubakoresha benshi ndetse nababigize umwuga.
Mu ntambara ya LED na LCD, uwatsinze nyabyo ni abareba, bungukirwa nubunararibonye bugenda butera imbere bugaragazwa nubuhanga bushya bwo kwerekana.
