Opanga Zipangizo za OLED Padziko Lonse Amalimbikitsa Kupanga Zinthu Mwatsopano mu Ukadaulo Wowonetsera wa Next-Gen

Opanga Zida za OLED Padziko Lonse Amawonetsa Zatsopano

Ukadaulo wa Organic Light-Emitting Diode (OLED), womwe umadziwika kuti ndi njira yowonetsera ya flat-panel yotsatira CRT, PDP, ndi LCD, ukupitiliza kusintha makampani a zamagetsi ndi magwiridwe antchito ake apamwamba komanso kusinthasintha kwake. Pogwiritsa ntchito zipangizo za organic semiconductor zomwe zimatulutsa kuwala pansi pa magetsi, OLED imapereka kapangidwe kolimba kwathunthu. kuphatikiza ubwino wa CRT'kusiyana kwakukulu ndi LCD'mbiri yopyapyala, pamene akuchotsa zovuta zakale.

Kapangidwe ka OLED ndi Magwiridwe Antchito

Chipangizo cha OLED chodziwika bwino chimakhala ndi zigawo zingapo zogwira ntchito, kuphatikizapo anode, hole injection layer (HIL), hole transport layer (HTL), organic emissive layer (EL), electron transport layer (ETL), electron injection layer (EIL), ndi cathode. Zigawozi zimapangidwa kuti zipange“masitepe"kapangidwe ka mphamvu (Chithunzi 1), kuthandiza kubwezeretsanso bwino mabowo ndi ma elekitironi mkati mwa gawo lotulutsa mpweya kuti apange kuwala. Njira zamakono zopangira doping zimawonjezera mphamvu (Matebulo 1-2), kukulitsa magwiridwe antchito a chipangizocho komanso moyo wake.

Zipangizo Zopangira Zinthu Zofunika Kwambiri

Kupanga kwa OLED kumadalira zida zapadera kwambiri zomwe zimapangidwa kuti zigwirizane ndi ukadaulo wa passive matrix (PM-OLED) ndi ukadaulo wa active matrix (AM-OLED). Machitidwe ofunikira ndi awa:

PM-OLED: Zida zoyeretsera ndi kuyikamo zinthu zachilengedwe.

AM-OLED:  Machitidwe ochotsera: Mapulatifomu otulutsa mpweya, plasma-enhanced chemical vapor deposition (PECVD), ndi vacuum thermal evaporation (VTE) ya zigawo za thin-film transistor (TFT).

Zipangizo zopangira mapatani: Zophimba, makina owonetsera, ndi zopukutira zouma/zonyowa zopangira ma TFT circuit.

Makina owonjezera: Mafumbi, mapaipi a gasi, ndi zida zochotsera mpweya pogwiritsa ntchito laser.

Kuyesa & kukonza: Zoyesa zamagetsi za TFT, zowunikira za OLED, ndi makina okonza laser.

Makampani opanga zida za OLED padziko lonse lapansi akulamulidwa ndi opanga apadera ku South Korea ndi Japan, komwe kuli akatswiri opanga zinthu zatsopano pakupanga zinthu mwanzeru, kupanga mapangidwe, ndi ukadaulo woyesera. Makampani otsogola alimbitsa malo awo kudzera mu kupita patsogolo pakupanga zinthu zotsogola komanso kukonza zokolola.NdiChofunika kwambiri pakupanga ma OLED panels ambiri omwe amagwiritsidwa ntchito m'mafoni a m'manja, ma TV, ndi zida zovalidwa.
