Inzira ya OLED Yerekana

OLED (Organic Light-Emitting Diode) bivuga diode kama itanga urumuri, igereranya ibicuruzwa bishya mubice byerekana terefone igendanwa. Bitandukanye nubuhanga gakondo bwa LCD, tekinoroji ya OLED ntabwo isaba itara ryinyuma. Ahubwo, ikoresha ultra-thin organic material coatings hamwe nikirahure cyibirahure (cyangwa substrate substrate substrate). Iyo amashanyarazi akoreshejwe, ibyo bikoresho kama bitanga urumuri. Byongeye kandi, ecran ya OLED irashobora gukorwa yoroheje kandi yoroheje, itanga impande nini zo kureba, kandi igabanya cyane gukoresha ingufu. OLED nayo irashimwa nkibisekuru bya gatatu byerekana tekinoroji. OLED yerekana ntabwo yoroheje gusa, yoroshye, kandi ikoresha ingufu nyinshi ariko kandi irata urumuri rwinshi, imikorere ya luminescence ikora neza, hamwe nubushobozi bwo kwerekana umukara wera. Byongeye kandi, zirashobora kugororwa, nkuko bigaragara muri tereviziyo igezweho ya ecran na telefone. Uyu munsi, inganda zikomeye mpuzamahanga zirimo guhatanira kongera ishoramari R&D muri tekinoroji ya OLED yerekana, bigatuma ikoreshwa cyane muri TV, mudasobwa (monitor), telefone zigendanwa, tableti, no mu zindi nzego. Muri Nyakanga 2022, Apple yatangaje gahunda yo kumenyekanisha ecran ya OLED kumurongo wa iPad mumyaka iri imbere. Moderi ya iPad 2024 igiye kugaragara izaba igizwe na paneli yerekana OLED nshya, inzira ituma izo panne zoroha kandi zoroshye.

Ihame ryakazi rya OLED ryerekana riratandukanye cyane na LCDs. Ahanini itwarwa numurima wamashanyarazi, OLEDs igera kumyuka yumucyo binyuze mu gutera inshinge no kongera guhuza abatwara ibicuruzwa mumashanyarazi ya semiconductor nibikoresho bya luminescent. Muri make, ecran ya OLED igizwe na miriyoni ntoya "itara."

Igikoresho cya OLED kigizwe ahanini na substrate, anode, urwego rwo guteramo umwobo (HIL), urwego rwo gutwara umwobo (HTL), urwego rwo guhagarika ibyuma bya elegitoronike (EBL), emissive layer (EML), icyuma gifunga umwobo (HBL), urwego rwo gutwara ibintu (ETL), urwego rwa elegitoronike (EIL), na cathode. Uburyo bwo gukora bwa OLED yerekana ikoranabuhanga risaba ubuhanga buhanitse cyane, bugabanijwe mubice byimbere-byanyuma. Imbere-impera yimbere ikubiyemo cyane cyane Photolithography hamwe nubuhanga bwo guhumeka, mugihe inzira yinyuma yibanda kuri encapsulation no guca tekinoroji. Nubwo tekinoroji ya OLED yateye imbere yiganjemo cyane na Samsung na LG, abakora ibicuruzwa byinshi mubushinwa nabo bakajije umurego mubushakashatsi bwabo kuri ecran ya OLED, bongera ishoramari mubyerekanwa bya OLED. OLED yerekana ibicuruzwa bimaze kwinjizwa mubitangwa byabo. Nubwo hari icyuho kinini ugereranije n’ibihangange mpuzamahanga, ibyo bicuruzwa bigeze kurwego rukoreshwa.
