Mumazuva ano emazuva ano epamusoro-yekupedzisira ekuratidzira tekinoroji, OLED (Organic Light-Emitting Diode) uye QLED (Quantum Dot Chiedza-Emitting Diode) pasina mubvunzo maviri makuru anotarisisa. Kunyangwe mazita avo akafanana, anosiyana zvakanyanya mumisimboti yehunyanzvi, mashandiro, uye maitiro ekugadzira, anenge achimiririra nzira mbiri dzakasiyana dzekusimudzira tekinoroji.
Zvikuru, OLED kuratidza tekinoroji yakavakirwa pamusimboti weorganic electroluminescence, nepo QLED ichitsamira pane electroluminescent kana photoluminescent mashandiro einorganic quantum dots. Sezvo inorganic zvinhu zvinowanzove nepamusoro kupisa uye kugadzikana kwemakemikari, QLED ine zvakanakira maererano nemwenje sosi kugadzikana uye hupenyu hurefu. Ichi zvakare chikonzero nei vazhinji vachifunga QLED senzira inovimbisa yeinotevera-chizvarwa kuratidza tekinoroji.
Zvichitaurwa zviri nyore, OLED inoburitsa mwenje kuburikidza ne organic zvinhu, nepo QLED inoburitsa mwenje kuburikidza neinorganic quantum dots. Kana LED (Chiedza-Emitting Diode) ichifananidzwa ne "amai," ipapo Q uye O inomiririra nzira mbiri dzakasiyana dze "baba" dzetekinoroji. LED pachayo, se semiconductor chiedza-emitting device, inofadza simba rechiedza apo ikozvino inopfuura nepakati pezvinhu zve luminescent, ichiwana photoelectric kutendeuka.
Kunyangwe zvese OLED neQLED zvichibva pane yakakosha mwenje-emitting musimboti weLED, iwo anodarika echinyakare maratidziro e LED maererano nekupenya kwakanaka, pixel density, kuita kwemavara, uye kutonga kwesimba rekushandisa. Zvakajairwa ma LED anoratidza anovimba ne electroluminescent semiconductor machipisi, ine iri nyore kugadzira maitiro. Kunyangwe yakakwira-density diki-pitch LED maratidziro anogona parizvino kuwana mashoma pixel pitch ye0.7 mm. Kusiyana neizvi, zvese OLED neQLED zvinoda yakanyanya kutsvagisa sainzi uye 工艺 zviyero kubva kune zvigadzirwa kusvika pakugadzira mudziyo. Parizvino, inyika shoma dzakaita seGermany, Japan, neSouth Korea dzine mukana wekupinda mucheni dzadzo dzepamusoro, zvichikonzera zvipingamupinyi zvakanyanyisa zvetekinoroji.
Nzira yekugadzira imwe mutsauko mukuru. Nzvimbo inoburitsa chiedza cheOLED ma organic molecules, ayo pari zvino anonyanya kushandisa evaporation process-kugadzirisa organic zvinhu muzvikamu zvidiki zvemamorekuru pasi petembiricha yakakwira uyezve kunyatsozviisa panzvimbo dzakatarwa. Iyi nzira inoda yakanyanyisa mamiriro ezvakatipoteredza, inosanganisira maitiro akaomarara uye chaiwo michina, uye zvakanyanya kukosha, inotarisana nezvinetso zvakakura mukuzadzisa zvinodiwa zvekugadzira zvehukuru-hukuru skrini.
Kune rumwe rutivi, chiedza-emitting centre yeQLED is semiconductor nanocrystals, inogona kunyungudutswa mumhinduro dzakasiyana-siyana. Izvi zvinobvumira kugadzirira kuburikidza nemhinduro-yakavakirwa nzira, senge tekinoroji yekudhinda. Kune rimwe divi, izvi zvinogona kunyatso kudzikisa mutengo wekugadzira, uye kune rimwe divi, zvinotyora zvipimo zvehukuru hwescreen, kuwedzera mamiriro ekushandisa.
Muchidimbu, OLED neQLED inomiririra iyo yepamusoro yeorganic uye inorganic light-emitting matekinoroji, imwe neimwe iine simba rayo uye kusasimba kwayo. OLED inozivikanwa nekunyanya kusiyanisa ratio uye inochinjika kuratidza maitiro, nepo QLED inofarirwa nekugadzikana kwayo kwezvinhu uye mutengo unogona. Vatengi vanofanira kuita sarudzo zvichienderana nezvinodiwa zvavo zvekushandisa.
