Ukuthenga i-TV kube nzima nakakhulu kulo nyaka. Ama-TV ane-LCD, i-QLED, i-Mini-LED, i-OLED kanye, kamuva nje, ubuchwepheshe be-QD-OLED ayatholakala. Ekuqaleni konyaka, abakwaSamsung bethule ubuchwepheshe bokuboniswa kwe-QD-OLED okukhulunywe ngabo ngenhla (okwethulwa okokuqala yi-Samsung S95B TV), abathi bungcono ngezindlela eziningi kunobuchwepheshe be-WRGB OLED obusetshenziswa ama-TV e-LG's esincintisana nawo. Kodwa ingabe kunjalo ngempela?
Ungaba nentshisekelo ku
I-QD-OLED iwuhlobo lwesibonisi esizikhiphayo, esifana nesibonisi seSuper AMOLED esitholakala kuma-smartphones namathebulethi. Galaxy. Lokhu kusho ukuthi iphikseli ngalinye kuphaneli ye-QD-OLED lingazikhanyisela ngokwalo futhi lidale owalo umbala. Ngaphezu kwalokho, iqukethe ama-nanocrystals e-quantum dot, aziwa ngezakhiwo ezikhanyayo ezingcono, imibala ejulile kanye nephalethi yombala obanzi.
Isibonisi se-WRGB OLED sisebenzisa ukukhanya kwangemuva okumhlophe okudluliswa kuzihlungi zombala omhlophe, obomvu, oluhlaza okotshani, noluhlaza okwesibhakabhaka ukuze kukhiqizwe imibala ehlukahlukene. Kukhona nephikseli emhlophe emhlophe. Okunye ukukhanya (ukukhanya) kuyalahleka njengoba kudlula ezihlungi zombala, okuholela ekukhanyeni okuphansi. Ngaphezu kwalokho, i-backlight emhlophe ayinembile kakhulu, ngakho-ke imibala eyakhayo ayihlanzekile ngokuphelele futhi igcwele.
Izinto eziphilayo ezisetshenziswa kuzikrini ze-OLED zingehlisa izinga ngokushesha uma zivezwa kumazinga aphezulu esikhathi eside okukhanya. Ngakho-ke i-LG kufanele iqaphele ukuthi isikhathi esingakanani ingagcina amazinga okukhanya aphezulu, ikakhulukazi ngokuqukethwe kwe-HDR. Ngakho-ke ama-TV e-OLED avamise ukufiphala ngemva kwemizuzu embalwa.
Ubuchwepheshe be-QD-OLED, ngokuphambene, busebenzisa ukukhanya kwangemuva okuluhlaza okwesibhakabhaka okumsulwa okudlula kumachashazi we-quantum ukukhiqiza imibala ebomvu, eluhlaza, noluhlaza okwesibhakabhaka. Amachashazi e-Quantum amunca amandla kunoma yimuphi umthombo wokukhanya, enze ukukhanya okumsulwa kwe-mono-frequency. Ubukhulu bamachashazi e-quantum bunquma ukuthi yimuphi umbala we-nanoparticles awukhiqizayo. Isibonelo, labo abanosayizi ongu-2 nm bakhipha ukukhanya okuluhlaza okwesibhakabhaka, kanti labo abanosayizi ongu-3 no-7 nm bangakhipha ukukhanya okuluhlaza nokubomvu. Ngenxa yokuthi zikhiqiza ukukhanya okumsulwa kwe-mono-frequency, ukukhiqizwa kombala kwephaneli ye-QD-OLED kungcono kunokwesikrini se-OLED.
Njengoba ukulahleka kwe-backlight kukuncane ngamaphaneli e-QD-OLED, azuza kakhulu kuwo futhi ngokuvamile akhanya kunezikrini ze-WRGB OLED. Ngaphezu kwalokho, zinikeza imibala ejulile, ama-engeli wokubuka abanzi kancane futhi awathambekele ekushisweni kwe-pixel. I-QD-OLED empeleni iwubuchwepheshe bokuqala be-OLED obuhlangabezana ngokugcwele nokukhanya okuphezulu kwe-Ultra HD Premium kanye nokucaciswa kokugqamayo okusethwe i-UHD Alliance.
Igalari yezithombe
Ngobuchwepheshe be-QD-OLED, abakwaSamsung balethe uguquko oluphathekayo engxenyeni ye-OLED TV. Manje kufanele silinde ama-TV we-QD-OLED ehle amanani afinyelele ezingeni labalingani bawo be-OLED, okungafanele kuthathe iminyaka embalwa.
Futhi i-LG isine-WOLED futhi… 🙂
