Bambanci tsakanin OLED da QLED

A cikin manyan fasahohin nuni na zamani, OLED (Organic Light-Emitting Diode) da QLED (Quantum Dot Light-Emitting Diode) babu shakka manyan abubuwan da suka fi mayar da hankali a kai guda biyu ne. Duk da cewa sunayensu iri ɗaya ne, sun bambanta sosai a cikin ka'idojin fasaha, aiki, da hanyoyin kera kayayyaki, kusan suna wakiltar hanyoyi biyu daban-daban na ci gaba don fasahar nuni.

Ainihin, fasahar nunin OLED ta dogara ne akan ƙa'idar electroluminescence ta halitta, yayin da QLED ta dogara ne akan hanyar electroluminescent ko photoluminescent na inorganic quantum drops. Tunda kayan da ba na halitta ba gabaɗaya suna da mafi girman kwanciyar hankali na zafi da sinadarai, a ka'idar QLED tana da fa'idodi dangane da kwanciyar hankali na tushen haske da tsawon rai. Wannan kuma shine dalilin da yasa mutane da yawa ke ɗaukar QLED a matsayin alkibla mai kyau ga fasahar nuni ta zamani.

A taƙaice dai, OLED yana fitar da haske ta hanyar kayan halitta, yayin da QLED ke fitar da haske ta hanyar digo-digo marasa tsari. Idan aka kwatanta LED (Haske-Emitting Diode) da "uwa," to Q da O suna wakiltar hanyoyi daban-daban guda biyu na fasaha "uban" na uba. LED da kanta, a matsayin na'urar samar da haske ta semiconductor, tana motsa makamashin haske lokacin da wutar lantarki ta ratsa kayan haske, wanda hakan ke haifar da canjin hasken lantarki.

Duk da cewa OLED da QLED sun dogara ne akan ƙa'idar LED mai fitar da haske, sun fi gaban allon LED na gargajiya dangane da inganci mai haske, yawan pixel, aikin launi, da kuma sarrafa amfani da makamashi. Allon LED na yau da kullun yana dogara ne akan guntuwar semiconductor na lantarki, tare da tsarin kera mai sauƙi. Ko da allon LED mai yawan yawa a halin yanzu zai iya cimma ƙaramin girman pixel na 0.7 mm kawai. Sabanin haka, duka OLED da QLED suna buƙatar bincike mai zurfi da ƙa'idodi na kimiyya daga kayan aiki zuwa kera na'urori. A halin yanzu, ƙasashe kaɗan ne kawai kamar Jamus, Japan, da Koriya ta Kudu ke da ikon shiga cikin sarƙoƙin samar da kayayyaki na sama, wanda ke haifar da shingen fasaha mai yawa.

Tsarin kera wani babban bambanci ne. Cibiyar OLED mai fitar da haske ita ce ƙwayoyin halitta, waɗanda a halin yanzu galibi suna amfani da tsarin ƙafewa - suna sarrafa kayan halitta zuwa ƙananan tsarin ƙwayoyin halitta a ƙarƙashin yanayin zafi mai yawa sannan a sake sanya su a wurare da aka ƙayyade. Wannan hanyar tana buƙatar yanayi mai tsanani na muhalli, ta ƙunshi hanyoyi masu rikitarwa da kayan aiki na musamman, kuma mafi mahimmanci, tana fuskantar ƙalubale masu yawa wajen biyan buƙatun samar da manyan allo.

A gefe guda kuma, cibiyar samar da haske ta QLED ita ce nanocrystals na semiconductor, wanda za a iya narkar da shi a cikin mafita daban-daban. Wannan yana ba da damar shiri ta hanyar hanyoyin da suka dogara da mafita, kamar fasahar bugawa. A gefe guda, wannan na iya rage farashin masana'antu yadda ya kamata, kuma a gefe guda, yana karya iyakokin girman allo, yana faɗaɗa yanayin aikace-aikace.

A taƙaice, OLED da QLED suna wakiltar manyan fasahohin samar da haske na halitta da na rashin halitta, kowannensu yana da ƙarfi da rauninsa. An san OLED da babban rabon bambanci da kuma yanayin nuni mai sassauƙa, yayin da aka fifita QLED saboda kwanciyar hankali da kuma yuwuwar farashi. Masu amfani da kayayyaki ya kamata su yi zaɓi bisa ga ainihin buƙatunsu na amfani.
