Ngaba i-OLED ingcono emehlweni akho?

Njengoko ixesha lokujonga isikrini liqhubeka lisanda kwihlabathi liphela, inkxalabo malunga nempembelelo yetekhnoloji yokubonisa kwimpilo yamehlo iye yanda. Phakathi kweengxoxo, umbuzo omnye uvelele: Ngaba itekhnoloji ye-OLED (Organic Light-Emitting Diode) ingcono ngokwenene emehlweni akho xa ithelekiswa nezikrini ze-LCD zemveli?'funda isayensi, iingenelo, kunye nezilumkiso zezikrini ze-OLED.

Izikrini ze-OLED zaziwa ngemibala yazo eqaqambileyo, ubumnyama obunzulu, kunye nokusebenza kakuhle kwamandla. Ngokungafaniyo nee-LCD, ezixhomekeke kwisibane sangasemva, i-pixel nganye kwiphaneli ye-OLED ikhupha ukukhanya kwayo. Olu yilo lukhethekileyo lubonelela ngeenzuzo ezimbini ezinokubakho zokukhululeka kwamehlo:

Ukukhutshwa kokukhanya okuluhlaza okwesibhakabhaka okusezantsi

Izifundo zibonisa ukuba ukuvezwa ixesha elide kukukhanya okuluhlaza okwesibhakabhaka**—ngakumbi kwi-400–Uluhlu lobude be-wavelength obuyi-450 nm—inokuphazamisa imijikelo yokulala kwaye inegalelo ekuxinezelekeni kwamehlo edijithali. Izikrini ze-OLED zikhupha ukukhanya okuluhlaza okwesibhakabhaka okuncinci kunee-LCD zemveli, ingakumbi xa zibonisa umxholo omnyama. Ngokwengxelo ka-2021 ye-*Harvard Health Publishing*, i-OLED'Ukukwazi ukufiphalisa iiphikseli ngazinye (endaweni yokusebenzisa isibane sangasemva esifanayo) kunciphisa umbane oluhlaza okwesibhakabhaka ngokubanzi ukuya kuthi ga kwi-30% kwimo emnyama.

Ukusebenza Okungenaziphazamisi

Izikrini ezininzi ze-LCD zisebenzisa i-PWM (i-Pulse Width Modulation) ukulungisa ukukhanya, okutshintsha ukukhanya kwangasemva ngokukhawuleza. Oku kufiphaza, okuhlala kungabonakali, kuye kwanxulunyaniswa neentloko ezibuhlungu kunye nokudinwa kwamehlo kubantu abanovelwano. Nangona kunjalo, izikrini ze-OLED zilawula ukukhanya ngokulungelelanisa ukukhanya kwe-pixel ngokuthe ngqo, zisusa ukufiphaza kwiimeko ezininzi.

Nangona ii-OLED zithembisa, impembelelo yazo kwimpilo yamehlo ixhomekeke kwiipateni zokusetyenziswa kunye nokusetyenziswa kwetekhnoloji:

I-PWM kwezinye ii-OLED Okumangalisayo kukuba, ezinye izikrini ze-OLED (umz., ii-smartphones ezingabizi kakhulu) zisasebenzisa i-PWM kwizicwangciso zokukhanya okuphantsi ukonga umbane. Oku kunokubuyisela imiba ekhanyayo.

Ukukhanya Okugqithisileyo:Izikrini ze-OLED ezibekwe kukukhanya okuphezulu kwiindawo ezimnyama zinokubangela ukukhanya, nto leyo ethintela iingenelo zazo zokukhanya okuluhlaza okwesibhakabhaka.

Iingozi zokutsha:Izinto ezizinzileyo (umz., iibha zokuhambisa) kwi-OLED zinokonakalisa ii-pixels ngokuhamba kwexesha, nto leyo ekhuthaza abasebenzisi ukuba bonyuse ukukhanya—okunokuba mandundu ukukhathala kwamehlo.

Iimbono zeengcali

UGqr. Lisa Carter, ingcali yamehlo kwiVision Health Institute, ucacisa athi:

"Ii-OLED ziyindlela ebhetele yokuphucula intuthuzelo yamehlo, ingakumbi ngenxa yokukhanya kwazo okuluhlaza okwesibhakabhaka okunciphileyo kunye nokusebenza kwazo okungenaziphazamisi. Nangona kunjalo, abasebenzisi kufuneka balandele umthetho we-20-20-20: rhoqo ngemizuzu engama-20, jonga into ekude ngeenyawo ezingama-20 imizuzwana engama-20. Akukho teknoloji yesikrini enokuthatha indawo yemikhwa esempilweni."

Okwangoku, abahlalutyi bezobuchwepheshe bagxininisa inkqubela phambili kwiindlela zokhathalelo lwamehlo ze-OLED:I-Samsung's "Isikhuselo seNtlalo-ntle yamehlo"ilungisa ukukhanya okuluhlaza okwesibhakabhaka ngokuguquguqukayo ngokusekelwe kwixesha losuku.I-LG's "Imbono Yokuthuthuzela"idibanisa ukukhanya okuluhlaza okwesibhakabhaka okuphantsi kunye neengubo ezichasene nokukhanya.

Izikrini ze-OLED, ezinomahluko aphezulu kunye nokukhanya okuluhlaza okwesibhakabhaka okuncitshisiweyo, zibonelela ngenzuzo ecacileyo yokuthuthuzela amehlo kunee-LCD zemveli—ukuba zisetyenziswa ngendlela efanelekileyo. Nangona kunjalo, izinto ezifana noseto lokukhanya, ukusebenza okungenamthungo, kunye nemikhwa ye-ergonomic zihlala zibalulekile.
