Enye yezinto ezinhle kakhulu zobuchwepheshe ukuthi isilethele izibonisi ze-OLED. Uma usemakethe yesibonisi sesimanje futhi ufuna sibe nezici ozilindele, kufanele nakanjani uhlole izibonisi ze-OLED. Kule nkathi esheshayo, kufanelekile ukwazi izinzuzo zokuboniswa kwe-OLED.
Yini i-OLED?
I-OLED isifinyezo se-"organic light-emitting diode". Elinye igama elithi "organic electroluminescent diode". Ikhipha ukukhanya ngokuqondile ngogesi, ngokungafani nendlela evamile yokukhipha ukukhanya ngokushisa imicu ngogesi. Izibonisi ze-OLED zenziwe ngezendlalelo ezincanyana zengilazi, ipulasitiki nama-molecule akhethekile asabela eshajelweni kagesi futhi akhiqize ukushisa okuphansi kakhulu. Ukuthinta isibonisi se-OLED cishe akunamfudumalo, okonga amandla amaningi, okuwukuthuthuka okukhulu kunezibonisi ze-CRT ezidla amandla kakhulu zesikhathi esidlule.
Umlando we-OLED
Ukutholakala kobuchwepheshe besimanje be-OLED kungalandelelwa emuva ku-1987. Ngaleso sikhathi, ososayensi ababili bakwaDonman Kodak, uSteven Van Slyke noChing Tang, bathola ezinye izinto eziphilayo ezingakhipha ukukhanya ngogesi ophansi. Kudala ngeminyaka yawo-1960, ukutholwa kwe-fluorescence ebambezelekile kwavula indlela yokuzalwa kwe-OLED. Nakuba izinto zakudala eziphilayo zazidinga amandla kagesi aphezulu ukuze zikhiphe ukukhanya, ososayensi be-Kodak baphumelele ukuzuza i-fluorescence ngogesi ophansi.
Laba sosayensi baqale benza ama-OLED ane-spectrum ephuzi-luhlaza, kwase kuba i-spectrum ewolintshi-bomvu, futhi ekugcineni banqoba umthetho wegebe lamandla ukuze bazuze ngempumelelo ukukhishwa kwe-diode ebomvu. Kamuva, njengoba ubuchwepheshe buthuthuka, izibonisi ze-OLED ezintsha njenge-AMOLED (i-matrix esebenzayo ye-organic light-emitting diode) yavela.
Izingxenye ezibalulekile zesibonisi se-OLED
Inhliziyo yesibonisi se-OLED i-OLED emitter. Kuyingxenye yemvelo ekhipha ukukhanya lapho kusetshenziswa ugesi. Isakhiwo esiyisisekelo sihlanganisa ungqimba lwezinto phakathi kwe-anode ne-cathode. Imishini yesimanje ye-OLED inezendlalelo eziningi zokuthuthukisa ukuqina nokusebenza kahle, kodwa umsebenzi oyisisekelo uhlala unjalo. Amaphaneli e-OLED akhiwe ngephaneli yangaphambili, iphaneli yangemuva, ama-electrode, isendlalelo se-encapsulation, ne-substrate. Lesi simiso sizwela kakhulu kumswakama nomoya-mpilo, ngakho-ke ungqimba lwe-encapsulation luyinkimbinkimbi kakhulu.
I-substrate
Isisekelo sezibonisi ze-OLED ingilazi noma i-plastic substrate, into esobala enikeza indawo ezinzile kwezinye izingxenye.
Izendlalelo Eziphilayo
Izendlalelo eziningi zezinto eziphilayo zifakwa ku-substrate, okuhlanganisa:
Isendlalelo esikhiphayo: Iqukethe ama-molecule e-organic akhipha ukukhanya ngaphansi kokuvuselela ugesi.
Isendlalelo sokuthutha izimbobo:Ihambisa amashaji avumayo (izimbobo) isendlalelo esikhiphayo.
Isendlalelo sezokuthutha nge-electron: Ithutha amashaji angemahle (ama-electron) aye kungqimba olukhiphayo.
Isendlalelo se-Transparent Conductive
Lolu ungqimba lutholakala nhlangothi zombili zongqimba lwezinto eziphilayo futhi lusebenza njenge-electrode esobala, evumela ukuthi okwamanje kugeleze kungene futhi kuphume ungqimba lwezinto eziphilayo.
I-Ecapsulation Layer
Ukuze kuvikelwe ungqimba oluthambile lwe-organic kumswakama nomoya-mpilo, ungqimba lwe-encapsulation luvame ukusetshenziswa phezulu, oluqukethe into evimbelayo evimbela izici zemvelo ukuthi zingathinti ungqimba lwe-organic.
Izinzuzo kanye nokubi kwesibonisi se-OLED
Izinzuzo
- Idizayini encane kakhulu:Izibonisi ze-OLED zincane kune-LCD nezibonisi ze-LED.
- Ukuvumelana nezimo:I-substrate ye-OLED ingaba yipulasitiki, iyenze ibe lula.
Ukukhanya okuphezulu: Isendlalelo esikhipha ukukhanya sikhanya kakhudlwana futhi asidingi ukusekelwa kwengilazi.
Ukusetshenziswa kwamandla okuphansi:Akukho ukukhanya kwangemuva okudingekayo, ukusetshenziswa kwamandla kuphansi, futhi kufanelekile kumadivayisi asebenza ngebhethri.
Kulula ukwenza:Ingenziwa ibe ngamasayizi amakhulu futhi isekele izinto zepulasitiki, okulula ukunweba.
Ukubi
Inkinga yombala:Izinto eziphilayo eziluhlaza okwesibhakabhaka zinesikhathi esifushane sokuphila.
Izindleko eziphezulu zokukhiqiza:Umswakama ungalimaza isistimu ye-OLED.
Izicelo zokubonisa i-OLED
Ubuchwepheshe be-OLED buye benza intuthuko enkulu ezinhlelweni ezahlukahlukene:
Ama-TV amakhulu:Ama-TV e-OLED aziwa ngekhwalithi yawo yezithombe ezinhle kakhulu.
Izimpawu Zedijithali:Isetshenziselwa ukuheha ukunaka ezitolo zezitolo, izindawo zokudlela, ezikhumulweni zezindiza, nokuningi.
Udonga Lwevidiyo:Udonga olukhulu lwevidiyo olwakhiwe izibonisi eziningi ze-OLED ukuze udale umuzwa ojulile.
Isibonisi Esibalulekile:ezisetshenziswa kumakalabha esithuthuthu ukunikeza ulwazi oludingekayo ngaphandle kokuphazamisa ukubona.
I-OLED esobala:ngezibonisi zezimoto nezingilazi zangempela ezingathandwa kwabathelisi esikubona.
Ungasikhetha Nini Isibonisi Se-OLED Sezinhlelo Zokusebenza Zezentengiselwano?
Izibonisi ze-OLED zinikeza ikhwalithi yokubukwayo enhle kakhulu yezinhlelo zokusebenza zezentengiso lapho okubonakalayo okumangalisayo kubaluleke kakhulu. Nazi ezinye izinto ezibalulekile ezicatshangelwayo:
• Okuqukethwe okunokulungiswa okuphezulu:Izibonisi ze-OLED ziyinketho enhle kakhulu lapho izithombe ezinokulungiswa okuphezulu, amavidiyo, noma izithombe zidinga ukuboniswa.
•Ama-engeli abanzi wokubuka:Izibonisi ze-OLED zinikeza ama-engeli wokubuka angaguquki, okuqinisekisa ukuthi okuqukethwe kwethulwa ngokunembile uma kubukwa ngama-engeli ahlukene.
•Idizayini ezacile futhi elula:Izibonisi ze-OLED zizacile futhi zilula kunezibonisi ze-LCD ezivamile, okuzenza zifanelekele izinhlelo zokusebenza lapho isikhala silinganiselwe noma kudingeka idizayini eshelelekile.
•Ukusetshenziswa kwamandla okuphansi:Izibonisi ze-OLED ziwonga kakhulu amandla kunezibonisi ze-LCD, zehlisa izindleko zokusebenza nomthelela wemvelo.
Uma uhlelo lwakho lokusebenza lwezentengiso ludinga ikhwalithi yesithombe enhle kakhulu, ama-engeli wokubuka abanzi, kanye nomklamo oshelelayo, isibonisi se-OLED singase sibe inketho engcono kakhulu.
Umehluko Phakathi kwe-OLED Vs LED/QLED Display
Izibonisi ze-LED zendabuko zisekelwe kubuchwepheshe be-LCD, isakhiwo esihlolwe isikhathi. Izikrini ze-LCD ziqukethe igridi encane yama-transistors asebenza kusetshenziswa ama-elementi amakristalu amancane. Le nqubo ibandakanya ukulawulwa kwamaphikseli amnyama nakhanyayo, kodwa ukuphuma kokukhanya kwangempela kuvela ekugcinweni kwama-LED. Indlela engcono kakhulu yokuhlola isikrini se-LCD ukusebenzisa i-backlight ye-LED, evumela ukugqama okuphezulu kanye nokufiphala kwesikrini okungcono, okwenza isibonisi sibe ngcono kunezinguqulo zangaphambilini. Ubuchwepheshe be-OLED buya phambili, buhlinzeka ngokuvikelwa kwamehlo futhi bungabangeli ukukhathala okubukwayo.
Ukwakhiwa kwezibonisi ze-QLED kuhluke kakhulu kuzibonisi ze-OLED. Izibonisi ze-QLED zisebenzisa amachashazi e-quantum, akhiqiza ukukhanya uma kunikwe amandla, okuthi akufane ne-OLED. Kodwa i-QLED iguqula ukukhanya okuluhlaza okwesibhakabhaka ekutholayo kube ukukhanya okumhlophe, okutholakala ngokusebenzisa amachashazi e-quantum abomvu naluhlaza okwesibhakabhaka. Izibonisi ze-QLED ziyakhanya, kodwa futhi zibiza kakhulu kune-OLED futhi zisezigabeni zokuqala zokuthuthuka. Ngokuphambene, izibonisi ze-OLED ziyakhanya ngokwazo, zibonisa imibala yazo, futhi zibiza kancane. Izibonisi ze-LED, ngakolunye uhlangothi, ziyiphaneli eyenziwe ngama-diode akhipha ukukhanya, futhi ngokuvamile isetshenziswa kumabhodi amakhulu nezimpawu.
