Ingabe i-OLED ingcono emehlweni akho?

Njengoba isikhathi sokubuka isikrini siqhubeka nokukhula emhlabeni jikelele, ukukhathazeka ngomthelela wobuchwepheshe bokubonisa empilweni yamehlo kuye kwanda. Phakathi kwezingxoxo, umbuzo owodwa uvelele: Ingabe ubuchwepheshe be-OLED (Organic Light-Emitting Diode) bungcono ngempela emehlweni akho uma kuqhathaniswa nezikrini ze-LCD zendabuko? Ake sithi.'funda isayensi, izinzuzo, kanye nezixwayiso zezibonisi ze-OLED.

Izikrini ze-OLED zaziwa ngemibala yazo egqamile, ubumnyama obujulile, kanye 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:

Ukukhishwa Kokukhanya Okuluhlaza okwesibhakabhaka Okuphansi

Ucwaningo lubonisa ukuthi ukuchayeka isikhathi eside ekukhanyeni okuluhlaza okwesibhakabhaka**—ikakhulukazi kuma-400–Ububanzi bobude be-wavelength obungu-450 nm—kungaphazamisa imijikelezo yokulala futhi kufake isandla ekucindezelekeni kwamehlo kwedijithali. Izikrini ze-OLED zikhipha ukukhanya okuluhlaza okwesibhakabhaka okuncane kune-LCD yendabuko, ikakhulukazi lapho kuboniswa okuqukethwe okumnyama. Ngokusho kombiko ka-2021 we-*Harvard Health Publishing*, i-OLED'Ikhono lokufiphaza amaphikseli ngamanye (esikhundleni sokusebenzisa isibani sangemuva esifanayo) kunciphisa ukukhishwa kokukhanya okuluhlaza okwesibhakabhaka okuphelele ngo-30% kumodi emnyama.

Ukusebenza Okungenaziphazamisi

Izikrini eziningi ze-LCD zisebenzisa i-PWM (Pulse Width Modulation) ukulungisa ukukhanya, okushintsha ukukhanya kwangemuva kube ngokushesha. Lokhu kufiphaza, okuvame ukungabonakali, kuye kwahlotshaniswa nekhanda elibuhlungu kanye nokukhathala kwamehlo kubantu abazwelayo. Izikrini ze-OLED, nokho, zilawula ukukhanya ngokulungisa ukukhanya kwe-pixel ngqo, zisuse ukufiphaza ezimweni eziningi.

Nakuba ama-OLED ethembisa, umthelela wawo empilweni yamehlo uncike emaphethini okusetshenziswa kanye nokusetshenziswa kobuchwepheshe:

I-PWM kwamanye ama-OLED Ngokumangalisayo, izikrini ezithile ze-OLED (isb., ama-smartphone angabizi kakhulu) zisasebenzisa i-PWM kuzilungiselelo zokukhanya okuphansi ukuze zonge amandla. Lokhu kungaphinde kubangele izinkinga zokukhazimula.

Ukukhanya Okukhulu Kakhulu:Izikrini ze-OLED ezibekwe ekukhanyeni okuphezulu ezindaweni ezimnyama zingase zibangele ukukhanya, okulwa nezinzuzo zazo zokukhanya okuluhlaza okwesibhakabhaka.

Izingozi Zokusha:Izinto ezimile (isb., imigoqo yokuzulazula) kuma-OLED zingonakala ngamaphikseli ngokuhamba kwesikhathi, okubangela abasebenzisi ukuthi bandise ukukhanya—okungenzeka kube kubi kakhulu ukucindezeleka kwamehlo.

Imibono Yochwepheshe

UDkt. Lisa Carter, udokotela wamehlo eVision Health Institute, uyachaza:

"Ama-OLED ayisinyathelo esihamba phambili sokunethezeka kwamehlo, ikakhulukazi ngokukhanya kwawo okuluhlaza okwesibhakabhaka okunciphile kanye nokusebenza okungenazibani. Kodwa-ke, abasebenzisi kufanele balandele umthetho we-20-20-20: njalo ngemizuzu engama-20, bheka into eqhele ngamamitha angama-20 imizuzwana engama-20. Abukho ubuchwepheshe besikrini obungathatha indawo yemikhuba enempilo."

Okwamanje, abahlaziyi bezobuchwepheshe baqokomisa intuthuko ezindleleni zokunakekelwa kwamehlo ze-OLED:I-Samsung's "Isivikelo Senduduzo Yamehlo"ilungisa ukukhanya okuluhlaza okwesibhakabhaka ngokuguquguqukayo ngokusekelwe esikhathini sosuku.I-LG's "Umbono Wenduduzo"ihlanganisa ukukhanya okuluhlaza okwesibhakabhaka okuphansi nezingubo ezilwa nokukhanya.

Izikrini ze-OLED, ngokugqama kwazo okuphezulu kanye nokukhanya okuluhlaza okwesibhakabhaka okuncishisiwe, zinikeza inzuzo ecacile yenduduzo yamehlo kune-LCD yendabuko—uma nje zisetshenziswa ngendlela efanele. Kodwa-ke, izici ezifana nezilungiselelo zokukhanya, ukusebenza okungenazibani, kanye nemikhuba ye-ergonomic zihlala zibalulekile.
