Yintoni OLEDs?

Kuthi kwakufika zoluntu lwamazwe ngamazwe ingqikelelo uphuhliso oluzinzileyo, nto leyo ibandakanya luhlaza lonke ushishino kunye ukuqonda ngakumbi kokusingqongileyo iimpahla yabathengi, banayo elithi "organic", umdla omkhulu kunye nemfuno. Kwaye OLEDs ke, wayexakekile. izisombululo ezintsha zobugcisa kunye neemveliso ezintsha soloko ukutsala ingqalelo abasebenzisi "phambili" ye, ukugcina isantya maxesha. Yintoni na - OLEDs, yintoni na le migaqo yomsebenzi wabo namathemba? Esi sesona sihloko eli nqaku.

Impela, bawela imbali

Electroluminescent ngeempawu zomgquba izinto yafunyanwa ngo-1950 yi-French yamachiza Andre Bernanoz. Kodwa kuphela ngo-1987 ukufunyanwa yafumana isisombululo zeteknoloji kwi yokuqala oled-isixhobo iveliswayo "Kodak". Kwaye ngo 2000, ekhemisi nje ezintathu - A. MacDiarmid kunye H. Shirakawa kunye A. Heeger - bawongwa ngeMbasa kaNobel ngenxa yezinto yakhe entsimini organic neeplastikhi tonkoprovodyaschih. Kuphela ngowama-2008, laya kwi lokuthengwa inkampani OSRAM oled-isibane yokuqala, elo kwenziwe iikopi-25 kuphela ngexabiso-25 amawaka euro. Namhlanje, le izibane kuqhuba iqela iinkampani ngexabiso euro 500, yaye kukho iindawo ezininzi kweli oled-technology: PHOLED, TOLED, FOLED nabanye ukuba iyaqondakala kuphela kwiingcali.

Apho okunjani?

Isimanga, kodwa ukusetyenziswa kwegama elithi "organic" kule meko akukho ngokunxulumene iimveliso zezilwanyana okanye imvelaphi yemifuno. OLEDs okanye oled (ukusuka IsiNgesi Organic Light esikhupha Diode), - i semiconductor eyenziwe ngezinto carbon elenza radiation xa idlula therethrough umsinga wombane. Zisetyenziswa zabo ukwenziwa kweemveliso zomgquba neyezinto (yeekharbon), into leyo eyenza ukuba kuthiwe organic LED.

Icebo komsindo

Le fowuni siquka izahlulo ezine: isiseko, lo anode, cathode, conductive kwaye izaleko radiative. Isiseko okanye zeendawana inokuba iglasi, iplastiki okanye zalo amacwecwe. Le anode i oxide indium doped kunye etotini. Conductive ezikroziswayo i esikhupha Ingaphandle Iipholima, libya ezinto ubunzima oganikhi khompawundi. Le cathode yenziwe kwi-aluminiyam, calcium, okanye ezinye iintsimbi.

Ithekhnoloji imisebenzi ngenxa zesayensi

ilight-esikhupha Organic walungiselela kumgaqo isonka. Uninzi umaleko obhityileyo semiconductors organic engena phakathi electrode raznozaryazhennymi (ezintle nezimbi). Kwaye amalungiselelo ngokusekelwe izinto ngaphaya - iglasi okanye iplastiki (umz, polyimide bhetyebhetye). Xa yangoku aqukuqela i electrode, ukuba ifom wamwisela kwamasuntswana (electron kunye quasiparticles). Kwi-avareji, umaleko ephilayo amasuntswana ziqwalaselwa kwaye ukudala excitation amandla ophezulu, nto leyo ebangela wokunciphisa ukukhanya imibala ezahlukeneyo nwebu ephilayo. Ngaloo ndlela AMOLED ngco ezibengezelayo okanye fosforetsentnye maleko organic.

Types Matrix ukukhanya di- organic

Oled-iziboniso kuhlobo matrix yahlulwe esebenzayo-matrix neyokwenziwa-matrix. Active-matrix izixhobo ezingcakacileyo-umboniso alawulwa transistors entsimini-ndlela, apho ibekwe phantsi kwale anode. In asonge-matrix umfanekiso senziwa ekudibaneni kwe anode kunye cathode imicwe aa Incopho na amalungiselelo, ngoxa ulawulo lwenziwa kwisekethe lwangaphandle. Xa lento uyijonga, kukho izikimu ezintathu umbala oled-ekhombisa:

• Kunye emitters eyahlukileyo elimbala - ezintathu matrix ephilayo ayikhuphi imibala ezintathu ezisisiseko (blue, oluhlaza kunye nobomvu) bomfanekiso avele kuwo.
• Kunye emitters ezintathu ezimhlophe kunye okucoca umbala okhethekileyo.
• emitters Blue aguqulwa amaza kwamaza ebomvu kunye noluhlaza.

isicelo lwangoku

Ekuhambeni kwexesha lethu, oled-technology zisetyenziswa ikakhulu kwimpucuko uzkospetsializovannyh. Holography kunye nombono ebusuku izixhobo, organic imiboniso oonomathotholo kunye iikhamera digital, phones screens kunye nezibane, TV kunye nokuhlolwa - konke oku leyinene yo oled-technology.

Ubomi inkonzo oled-izixhobo

Zonke izixhobo zale mihla, ngokusebenzisa obu bugcisa, kungekudala kwabonakala Ukudinwa umbala ukukhanya. Kwanaxa lokuvula kwafunyaniswa ubu OLEDs komoya. ukusebenza Resource le isixhobo namhlanje zicingeleka ngokoqobo ivaliwe xa yobumhlophe lehle nge-50%. Nokusebenza wayeka ukuba index lithile amalunga nama-70%. Kodwa iinkampani imali kuphuhliso yezi teknoloji zizala amaduna namathokazi - kuqhele ukuba kwindawo iyatshintsha siyishiye isixhobo phambi kokuba efanelekileyo kufutshane isiphelo sobomi.

engcono kakhulu

Eyona inkulu amaplanga i organic ukukhanya-di- kuba namhlanje - kukuthi udibaniso edityanelweyo iprojekthi bemibutho OSRAM, Philips, Novaled, Fraunhoter IPMS. Ubungakanani yolawulo - cm 33 ukuya 33, indawo yingxenye - 828 square metres. cm, kwaye beso ratio - 76%. Xa ukukhanya 1 amawaka candelas square metre yokumpompoza ukukhanya amasuntswana of lumens 25 watt nganye nganye. Ithengisiwe namhlanje, iphaneli inkampani inkulu Lumiotec uba ubungakanani-15 ngo-15 cm kunye wampompoza ubalaseleyo lumens 60 watt nganye, nto leyo ilingana nebhalbhu zokukhanyisa ezibengezelayo. A Panasonic Corporation izicwangciso 2020 ukuya baqalise umboniso oled emarikeni wampompoza ubalaseleyo lumens 128 watt nganye. Ekubeni kuphazanyiswa American iqumrhu likazwelonke, nto leyo ngezithembiso amaplanga kwemali amanani ukuya ku-170 lumens ngalinye watt.

Amathemba oled-panels

Uninzi imifuziselo ezikhoyo ezi AMAGQABAZA ▸ namhlanje. Iduru, zenziwe ngeebhetshi elinganiselweyo, musa agobe, ukanti kakuhle ngokwaneleyo. iinkampani ezinkulu ziya kujolisa ekunciphiseni iindleko zeprojekthi, ukunyusa ubungakanani kunye nokuphucula kwemveliso. Iingcali ukuqikelela ukuvela mass imveliso kunye namaxabiso afikelelekayo kwi kwimarike yehlabathi ngo-2020.

Oled-ukukhanyisa

OLEDs e ikhanyisa kodwa emarikeni usaqala. Imveliso Mass le mveliso sele akukabikho usungule naliphi na ishishini. Ixabiso izibane loo yayisathe eliphezulu umlinganiselo umthengi, kwaye ukukhanya kunye nobomi bebhetri ulihlwempu. Ingeniso 75 billion US zeedola phezu kwelimiweyo emarikeni, oko kukuthi, masilivakalise oled-ukukhanyisa - a kunokuba encinane imali. Abathengi ezi mveliso abangekho bendalo, kunye nezinye iinkampani ukuba bekwi kuyilo ifanitshala indawo, kwakunye corporation kushishino ngomatshini.

Ubuhle nobubi

Xa OLEDs, kukho ezilungileyo nezingalunganga. Phakathi zingenakuphikwa ukusetyenziswa yokuqala yabo amandla efanayo distribution ukukhanya ukunqamleza manqwanqwa, kahle eliphezulu, ukhathalelo lwendalo kunye ukukhanya. Kodwa inzuzo iphambili - lithuba lokuba ndibanike bhetyebhetye kunye ngobuciko. A Ububi lo ode inkonzo ubu, iingxaki eninzi nawobuchwepheshe (icandelo zomgquba oxidized kwi wadibana ngamanzi, esifuna uphawu ezongezelelweyo). Kodwa iinkampani kuqhubeka ukutyala imali kuphuhliso bugcisa, wabona kuzo kwixesha elizayo electronic.

Ingaba Eco-friendly

Le oled-izinto azinamgaqo enzima kunye nezinto eziyityhefu ezifana mercury. Luqhubekekisiwe lula kwaye musa ukuba umrhumo okhethekileyo kunye nesikhundla processing eyongezelelweyo kulahlwa. Iridium phosphorescent izibane oled is non-ezinetyhefu, kunye yayo nemali kakhulu encinci. Zokuhamba angamarhoqorhoqo, ukukhanya oled-panels kufuna izibonelelo ezimbalwa, ukunciphisa iindleko, kwaye yehlise umthwalo kokusingqongileyo. Ngokomzekelo, omnye oled-oxwesileyo TV imonitha ye intshi 55 abe ubukhulu ka-4 mm, kwaye inobunzima malunga 5.4 eekhilogram.

Fantasy uba ngokoqobo

Nangona kugxeka ezinye iingcali, uninzi ukholelwa ukuba oled-iteknoloji iya kuba idabi enkulu kule nkulungwane yama-21. iiprojekthi Fantastic laba ngokoqobo, ezizezi:

• Kuyinto ezi technologies kuya kudala hayi nolulahlekisayo, yaye olusengqiqweni umfanekiso-ntathu.
• Ukukhanyisa yonke indawo oled-izibane.
• Imbonakalo solar panel ngaphaya.
• Monitors igajethi Flexible ungalunga epokothweni yakho.
• Kakhu- monitor ezilula kunye nomgangatho umbala ophezulu kunye engile nokubukela ebanzi kuya kuba impendulo ekhawulezileyo, ubukhulu nobuncinane kunye nomlinganiselo.
• Ukusetyenziswa kobuchwepheshe kwishishini ukuziphendulela ngokubanzi iyamangalisa.
• Kodwa ke iingubo ezikhanyayo bavela yeengqokelela umyili.

Kodwa musa ayeke khona - sisaci abaphengululi kunye neengcali. isayensi Modern kukade icangcisiwe kwindawo bifurcation xa olufumanayo siwutshintshe uphuhliso ngempucuko kwicala ukwazeka ngokupheleleyo. Imizekelo ezinjalo ezifunyaniswe ndityebile, oko ukuzaliseka ityhubhu emoyeni Krasnikova, kunye nokufunyanwa khompawundi eziphilayo kwindawo enzulu. Namhlanje Vanguard ye elektroniki - OLEDs, yaye ngomso - ngubani owaziyo?
