Ingabe I-OLED Ingcono Kwamehlo Akho?

Njengoba isikhathi sesikrini siqhubeka sikhuphuka emhlabeni wonke, ukukhathazeka ngomthelela wobuchwepheshe bokubonisa empilweni yamehlo kuye kwanda. Phakathi kwezinkulumo-mpikiswano, umbuzo owodwa uyagqama: Ingabe ubuchwepheshe be-OLED (Organic Light-Emitting Diode) bungcono ngempela emehlweni akho uma buqhathaniswa nezikrini ze-LCD zendabuko? Vumela's ingena kusayensi, izinzuzo, nemihume yezibonisi ze-OLED.

Izikrini ze-OLED zaziwa ngemibala yazo egqamile, emnyama ejulile, nokusebenza kahle kwamandla. Ngokungafani nama-LCD, athembele ekukhanyeni kwangemuva, iphikseli ngayinye kuphaneli ye-OLED ikhipha ukukhanya kwayo. Lo mklamo oyingqayizivele unikeza izinzuzo ezimbili ezingaba khona zokunethezeka kwamehlo:

I-Lower Blue Light Emission

Ucwaningo luphakamisa ukuthi ukuchayeka isikhathi eside ku-**light blue**-ikakhulukazi kuma-400-450 nm ububanzi begagasi-ingaphazamisa imijikelezo yokulala futhi ibe nomthelela ekucindezelekeni kwamehlo edijithali. Izikrini ze-OLED zikhipha ukukhanya okuluhlaza okuncane kunama-LCD omdabu, ikakhulukazi uma sibonisa okuqukethwe okumnyama. Ngokombiko wango-2021 we-*Harvard Health Publishing*, i-OLED'Ikhono lokufiphalisa amaphikseli angawodwana (esikhundleni sokusebenzisa i-backlight efanayo) kunciphisa ukuphuma kokukhanya okuluhlaza kufika ku-30% kumodi emnyama.

Ukusebenza Okungacwayizi

Izikrini eziningi ze-LCD zisebenzisa i-PWM (Pulse Width Modulation) ukuze zilungise ukukhanya, okuzungeza ngokushesha ukukhanya nokuvala ukukhanya kwangemuva. Lokhu kubhayiza, ngokuvamile okungabonakali, kuye kwaxhunyaniswa nobuhlungu bekhanda nokukhathala kwamehlo kubantu abazwelayo. Izikrini ze-OLED, nokho, zilawula ukukhanya ngokulungisa ukukhanya kwe-pixel ngokuqondile, kususe ukucwayiza ezimeni eziningi.

Ngenkathi ama-OLED ebambe isithembiso, umthelela wawo empilweni yamehlo uncike emaphethini okusetshenziswa nasekusetshenzisweni kwezobuchwepheshe:

I-PWM Kwamanye Ama-OLED Kuyamangaza ukuthi, izibonisi ezithile ze-OLED (isb, ama-smartphones esabelomali) zisasebenzisa i-PWM ngezilungiselelo zokukhanya okuphansi ukonga amandla. Lokhu kungase kuphinde kwethule izinkinga ezisheshayo.

Ukukhanya Okudlulele:Izikrini ze-OLED ezisethwe ekukhanyeni okuphezulu kakhulu ezindaweni ezimnyama zingase zibangele ukuxhopha, kuphikisane nezinzuzo zazo zokukhanya okwesibhakabhaka.

Izingozi zokushiswa:Izakhi ezimile (isb, amabha okuzulazula) kuma-OLED zingehlisa izinga lamaphikseli ngokuhamba kwesikhathi, kwenze abasebenzisi bakhulise ukukhanya.-ukucindezeleka kwamehlo okungenzeka kube kubi kakhulu.

Imibono Yochwepheshe

UDkt. Lisa Carter, udokotela wamehlo e-Vision Health Institute, uyachaza:

“Ama-OLED ayisinyathelo esiya phambili sokunethezeka kwamehlo, ikakhulukazi ngokukhanya kwawo okuluhlaza okwehlisiwe nokusebenza okungacwayizi. Kodwa-ke, abasebenzisi kusafanele balandele umthetho we-20-20-20: njalo ngemizuzu engama-20, bheka okuthile okungamamitha angama-20 imizuzwana engama-20. Abukho ubuchwepheshe besikrini obungangena esikhundleni semikhuba enempilo.”

Ngaleso sikhathi, abahlaziyi bezobuchwepheshe bagqamisa intuthuko ezindleleni zokunakekelwa kwamehlo ze-OLED:I-Samsung's “I-Eye Comfort Shield”ilungisa ngokuguqukayo ukukhanya okuluhlaza okwesibhakabhaka ngokusekelwe esikhathini sosuku.LG's “Comfort View”ihlanganisa ukukhanya okuluhlaza okwesibhakabhaka okuphansi nama-anti-glare coatings.

Izikrini ze-OLED, ezinokugqama kwazo okuphezulu nokukhanya okuluhlaza okwehlisiwe, zinikeza inzuzo ecacile yokunethezeka kwamehlo ngaphezu kwama-LCD omdabu-inqobo nje uma zisetshenziswa ngokuzibophezela. Kodwa-ke, izici ezifana nezilungiselelo zokukhanya, ukusebenza okungacwayizi, kanye nemikhuba ye-ergonomic kusabalulekile.
