Ubuso boLuntu obuPhezuluyo buDlulisa iSiphumo esiCacileyo
Kwabaninzi abanomdla kwi-AV, ubuchwepheshe be-LCD yesikrini asinqumanga . Ukungakwazi kwayo - ukusebenzisa ubuchwepheshe bezinto ezikhoyo, nokuba kunjalo-ukunikezela ngokukhanyisa okwenene okukhoyo kuthetha ukuba akunakukwazi ukunika abalandeli befilimu ukungafani kunye nobude bamanqanaba obumnyama babo abanomdla wokuthanda i-movie. Kakhulu kangangokuthi abalandeli abaninzi be-AV basasebenzisa ii-TV ezipheleleyo ze-HD plasma, apho nganye ipikseli inokuvelisa ukukhanya kwayo, kunokuphucula kwii-4K ze-LCD ze-LCD.
Cue technology OLED. Lolu hlobo olutsha uhlobo lwefomati yeskrini lubonisa iipekseli ezenza ngamnye umgangatho wokukhanya kunye nombala-kodwa ngokungafani nezikrini ze-plasma (eziye zavalwa ngo-2013) izikrini ze-OLED zingafanelana nemali efunekayo yamaphikseli kwizikrini zazo ukuze ivelise i-4K / UHD sigqibo. (Ukuze uthole iinkcukacha ezininzi zokuba kutheni abantu bevuya kakhulu nge-teknoloji ye-OLED, khangela iiNzuzo ezinhlanu eziPhambili ze-OLED.)
Oku kuphakamisa ithemba lokunika abalandeli beTV ye-plasma uhlobo lobuqhetseba kunye nokwahlukileyo bayamqwenela kodwa ngamaxesha amaninzi ama-pixels aphonswa ngokufanelekileyo. Nangona i-OLED ibonakala ngathi kwiphepha ukuba yiloo nto igqirha lika-AV, kodwa, awukwazi ukubetha intloko edala eyadala ukukhupha ukuze iqinisekise ukuba ikhona. Ingakumbi ukuba loo ntloko ikhankanywa phambi kwabaphulaphula uluntu ngokuchanekileyo uhlobo lwabalandeli be-AV banokukhetha ukonga iPlasma ngaphezu kweLCD.
Ngale nto engqondweni, i-website ye-UK AV ehlonishwayo ye-hdtvtest.co.uk isandul 'ukuza kunye ne-Leeds Trinity University kunye nomthengisi wase-UK uCrampton & Moore ukuseta umboniso karhulumente phakathi kweeTV ezitshisa kakhulu kwi-block - i-LG 65EF9500 ne-Panasonic 65CZ950 - kunye nawaphi amaninzi abonwa ngokuba yiyure ephezulu kakhulu ye-plasma, iPanasonic TC-P60ZT60.
Abaphulaphuli be-shoot-out babenabantu abathandekayo abangama-30 ababengabhaliswa ngaphambili kwisiganeko se-HDTVestest. Ukwenza ukuba ukhuphiswano lube luncedo kangangoko kunokwenzeka ukuba nganye iTV isetyenziswe kwiqondo lobuchwepheshe be-HDTVTest of calibration experts, kwaye yondla ngokufanayo inzame zokuhlola ukusuka kuGrivity, i-Skyfall kunye neHarry Potter kunye ne-Deathly Hallows Ingxenye yesiBini.
Ababekhoyo babuzwa nje ukuba bavote ukuba yiphi isikrini abavalelwa bekhupha umgangatho ophezulu kakhulu wesithombe - kwaye iziphumo zinyani ngokugqithiseleyo ekuthandeleni i-OLED kunokuba abalandeli be-OLED abanokufa babenokuqikelela.
Kwamavoti angama-28 abalwa, akukho ngaphantsi kwe-88% eya kwii-OLED izikrini. Ukuze kube ngokuchanekileyo, iPanasonic 65CZ950 ibanjwe amavoti angama-12, i-LG 65EF9500 yafumana amavoti angama-11, kwaye iTV ye-plasma ye-plasma eyayisakuba yinto ephakamileyo yamisa ama-matatu kuphela.
Betshelwa ukuba bangenwe nkcukacha ngesizathu sokuba bachithwe ziingqungquthela ze-OLED, abavoti bathetha ukuba bazivele izikrini ze-OLED ezivelisa i-punchier, abamhlophe abamhlophe kunye nabafundi abamnyama, abangaphezulu kwemvelo kunobumba be-plasma. Kwakungekho zonke iindaba ezimbi kwi-plasma ebekwe, nangona kunjalo, njengoko abavoti bebanokugxininisa ukuba iqhube kakuhle kakuhle kwi-90% yezixhobo zokuvavanya. Kwakhona, baziva, baphumelele ii-OLED ngokucacileyo okucacileyo kwaye xa kugcinwa abantu abamnyama kwizinga 'lokumnyama elikufutshane.'
Ngelixa i-LG OLED idibene ngaphandle kwePanasonic 65CZ950, okwangoku, i-LG inokuthi ibone umphumo njengento enhle xa ucinga ukuba i-65EF9500 esetyenziselwa ukuvavanya iindleko ezincinci kangangoko iPanasonic 65CZ950 ufumana ukukhululwa kwe-US, okungaqinisekanga okwamanje.
Amava am ngamazwe asemgangathweni yehlabathi le-plasma kunye nezikrini ze-OLED zakutshanje kuthetha ukuba iziphumo zokudubula azifiki into emangalisayo; Ndide ndiziva ukuba i-OLED inokufikelela kwiindawo zendawo apho i-plasma ayikwazi. Nge-LG ngoku ngokuthembisa ukuba kukho ukuphucula umfanekiso omkhulu kwisizukulwana sayo esilandelayo se-TV ye-OLED kunye nezinye iingcamango ezingenakunqwenelekayo, ikhangeleka njengokuba ekugqibeleni ixesha lokuhambisa i-plasma ibe yinto enomdla kodwa isigxina.
