Lub hauv paus ntsiab lus ntawm OLED zaub yog raws li cov organic teeb pom kev zoo -emitting diode technology, uas ua rau luminescence los ntawm cov cab kuj txhaj tshuaj thiab recombination.
Lub hauv paus ntsiab lus tseem ceeb ntawm OLED (Organic Light Emitting Display) yog siv cov khoom siv hluav taws xob cov khoom siv hluav taws xob thiab cov khoom siv luminescent los ua luminescence los ntawm cov cab kuj thiab kev sib txuas hauv qab hluav taws xob. Nws cov qauv yooj yim suav nrog nyias thiab pob tshab indium tin oxide (ITO) electrode nrog cov khoom siv hluav taws xob txuas nrog cov hluav taws xob zoo ntawm lub hwj chim, ntxiv rau lwm cov hlau cathode los ua ib qho qhaub cij -zoo li cov qauv. Tag nrho cov txheej txheem muaj xws li lub qhov thauj txheej (HTL), lub teeb -emitting txheej (EL) thiab ib txheej thauj hluav taws xob (ETL).
Thaum lub sijhawm ua haujlwm ntawm OLED zaub, cov khoom siv hluav taws xob thiab qhov tau txhaj tshuaj los ntawm cathode thiab anode mus rau hauv electron thiab lub qhov thauj cov khaubncaws sab nraud povtseg, feem, thiab tom qab ntawd tsiv mus rau lub teeb -emitting txheej los ntawm cov txheej txheem thauj khoom no. Nyob rau hauv lub teeb -emitting txheej, electrons thiab qhov sib ntsib thiab tsim excitons, excite light- emitting molecules, thiab emit pom lub teeb tom qab hluav taws xob so. Qhov tshwm sim luminescence no yog tus yam ntxwv ntawm tam sim no -hom organic teeb- emitting li, thiab cov luminescence siv yog proportional rau cov tshuaj tam sim no. Yog li ntawd, OLED cov lus muaj qhov zoo ntawm cov duab zoo, tag nrho saib lub kaum ntse ntse, siab brightness, zoo sib xws, dav xim ntau, tsawg zog noj, thiab lwm yam, thiab tau dav siv nyob rau hauv cov khoom siv xws li computer saib, xov tooj ntawm tes, handheld game consoles, thiab TV cov ntxaij vab tshaus.
Tsis tas li ntawd, kev sib txuas lus pins ntawm OLED cov lus muaj xws li ob hom: SPI thiab I2C. SPI kev sib txuas lus sai dua, tab sis I2C kev sib txuas lus yog nrov dua vim muaj tsawg tus pins. Txhua lub hwj chim thiab kev sib txuas lus pins yog tswj los ntawm SSD1306 tus neeg tsav tsheb, kom ntseeg tau tias kev ua haujlwm tau zoo thiab cov txiaj ntsig ntawm OLED zaub.
