Kwiiforam ezinkulu zedijithali kunye namaqonga eendaba zoluntu, nanini na xa kukhutshwa ii-smartphones ezintsha, kuvela izimvo ezifana nokuthi “izikrini ze-OLED zinzima emehlweni” kunye “nezikrini ezibangela ubumfama”, abasebenzisi abaninzi bade bathi “i-LCD ilawula ngonaphakade.” Kodwa ngaba izikrini ze-OLED ziyingozi ngokwenene njengoko amarhe esitsho? Eli nqaku liza kubonelela ngohlalutyo olunzulu lomahluko wezobuchwepheshe phakathi kwezikrini ze-OLED kunye ne-LCD kwaye lihlolisise impembelelo yazo kwimpilo yokubona.
Itekhnoloji yokubonisa ye-OLED (Organic Light-Emitting Diode) isebenzisa umgaqo wokuzikhanyisa, isusa isidingo semodyuli yokukhanya kwangasemva. Oku kuvumela ukuba ubukhulu besikrini bulawulwe ngaphakathi kwe-1 millimeter, nto leyo eyenza ukuba sibe ncinci malunga nesibini kwisithathu kunezikrini ze-LCD zemveli. Le teknoloji ayifezekisi nje kuphela ii-engile zokubukela ezibanzi kunye nokusebenza kombala okuqaqambileyo kodwa ikwanciphisa kakhulu ukusetyenziswa kwamandla, nto leyo eyenza ukuba ibe lolona khetho lukhethwayo kwiifowuni eziphathwayo eziphezulu, iiTV, kunye nezinye izixhobo. Iimpawu zayo eziguquguqukayo ezizodwa ziye zaqhubela phambili uphuhliso lwezikrini ezigobileyo kunye netekhnoloji yeminwe engaboniswanga kakuhle, nto leyo ebonisa ngokupheleleyo indima ebalulekileyo ye-OLED kwizixhobo ze-elektroniki zanamhlanje.
Nangona kunjalo, abanye abasebenzisi baxela ukuba banokudinwa kokubona lula xa bejonga izikrini ze-OLED, nto leyo enxulumene kakhulu nendlela yokufiphalisa isikrini. Izikrini ze-LCD zihlala zisebenzisa i-DC dimming, elungisa ukukhanya kwe-backlight ukuze kufezekiswe umboniso ongena-flicker. Ngokwahlukileyo koko, uninzi lwezixhobo ze-OLED zisebenzisa itekhnoloji yokufiphalisa ye-PWM (Pulse Width Modulation), elawula ukukhanya ngokutshintsha nokucima ii-pixel ngokukhawuleza. Kwiindawo ezinokukhanya okuphantsi, olu mjikelo olukhanyayo nomnyama rhoqo lunokubangela ukungakhululeki kwamehlo kubantu abanovelwano.
Ngokwembono yokuthuthuzela okubonakalayo, zombini ezi teknoloji zinezibonelelo zazo: Imvelaphi emnyama ye-OLED kunye nomahluko ophezulu kunokunciphisa umthwalo wokulungiswa kwamehlo, okwenza ukuba ifaneleke ngakumbi ukusetyenziswa kwiindawo ezimnyama. Okwangoku, ukukhanya okufana kwe-LCD kubonelela ngenzuzo ngexesha lokufunda umbhalo ixesha elide. Iingcali zicebisa ukuba abasebenzisi abanovelwano bakhethe izikrini ze-LCD ezine-DC dimming okanye izixhobo ze-OLED ezine-PWM dimming ephezulu, ngelixa abasebenzisi abaneemfuno zombala ezinamandla kufuneka bakhethe iimveliso ze-OLED ezixhotyiswe ngetekhnoloji ye-DC/high-frequency PWM.
Lilonke, ukugqiba nje ukuba "i-OLED iyingozi ngakumbi emehlweni" kuyathambekela. Xa kuthengwa izixhobo, abathengi kufuneka babhekisele kwiingxelo zovavanyo ezithile ezivela kwiiarhente zovavanyo lobuchwepheshe ezingochwephesha kwaye benze ukhetho ngokusekelwe kwimikhwa yabo yokusebenzisa kunye nobuntununtunu bokubona.
