Ezinkundleni ezinkulu zedijithali kanye nasezinkundleni zokuxhumana, noma nini lapho kukhishwa ama-smartphone amasha, kuvela amazwana anjengokuthi “izikrini ze-OLED zikhathaza amehlo” kanye “izikrini ezibangela ubumpumputhe”, abasebenzisi abaningi baze bathi “i-LCD ihlala ibusa.” Kodwa ingabe izikrini ze-OLED ziyingozi ngempela njengoba amahemuhemu esikisela? Lesi sihloko sizohlinzeka ngokuhlaziywa okujulile komehluko wezobuchwepheshe phakathi kwezikrini ze-OLED neze-LCD futhi sihlole umthelela wazo wangempela empilweni yokubona.
Ubuchwepheshe bokubonisa be-OLED (Organic Light-Emitting Diode) busebenzisa isimiso esizikhanyisayo, kususa isidingo semojuli yokukhanya kwangemuva. Lokhu kuvumela ukujiya kwesikrini ukuthi kulawulwe ngaphakathi kwe-millimeter eyi-1, okwenza kube mncane cishe izingxenye ezimbili kwezintathu kunezikrini ze-LCD zendabuko. Lobu buchwepheshe abugcini nje ngokufeza ama-engeli okubuka abanzi kanye nokusebenza kombala okugqamile kodwa futhi bunciphisa kakhulu ukusetshenziswa kwamandla, okwenza kube ukukhetha okuthandwayo kwama-smartphones aphezulu, ama-TV, namanye amadivayisi. Izici zayo eziguquguqukayo ezihlukile ziye zaqhubekisela phambili ukuthuthukiswa kwezikrini ezigobile kanye nobuchwepheshe beminwe obungabonisi kahle, okubonisa ngokugcwele indima ebalulekile ye-OLED kumadivayisi kagesi esimanje.
Kodwa-ke, abanye abasebenzisi babika ukuthi babhekana nokukhathala kokubona kalula lapho bebuka izikrini ze-OLED, okuhlobene kakhulu nendlela yokufiphaza isikrini. Izikrini ze-LCD zivame ukusebenzisa ukufiphaza kwe-DC, okulungisa ukukhanya kwesibani sangemuva ukuze kufezwe ukubonisa okungenazibani. Ngokuphambene nalokho, amadivayisi amaningi e-OLED asebenzisa ubuchwepheshe bokufiphaza be-PWM (Pulse Width Modulation), obulawula ukukhanya ngokushintsha nokuvala amaphikseli ngokushesha. Ezindaweni zokukhanya okuphansi, lokhu kujikeleza okukhanyayo nobumnyama ngezikhathi ezithile kungabangela ukungakhululeki kwamehlo kubantu abazwelayo.
Ngokombono wokunethezeka kokubona, zombili lezi zobuchwepheshe zinezinzuzo zazo: Isizinda esimnyama esimsulwa se-OLED kanye nokugqama okuphezulu kunganciphisa umthwalo wokulungiswa kwamehlo, okwenza kube kuhle kakhulu ukusetshenziswa ezindaweni ezimnyama. Okwamanje, ukukhanya okufana kwangemuva kwe-LCD kunikeza inzuzo ngesikhathi sokufunda umbhalo isikhathi eside. Ochwepheshe batusa ukuthi abasebenzisi abazwelayo bakhethe izikrini ze-LCD ezine-DC dimming noma amadivayisi e-OLED ane-PWM dimming ephezulu, kuyilapho abasebenzisi abanezidingo zombala eziqinile kufanele bakhethe imikhiqizo ye-OLED efakwe ubuchwepheshe be-DC/high-frequency PWM.
Sekukonke, ukuphetha ngokuthi “i-OLED iyingozi kakhulu emehlweni” kuyachelela. Lapho bethenga amadivayisi, abathengi kufanele babhekisele emibikweni ethile yokuhlola evela ezinhlanganweni zokuhlola ubuchwepheshe zobungcweti futhi benze izinqumo ngokusekelwe emikhubeni yabo yokusebenzisa kanye nokuzwela kokubona.
