YLED vs OLED
OLED yog qhov tshwj xeeb ntawm Lub Teeb Emitting Diodes (LED). Thaum cov txheej txheem organic siv hauv kev tsim cov LEDs, lawv hu ua OLEDs. Ob lub thev naus laus zis tau siv dav hauv cov khoom siv niaj hnub no. Lawv pab txo qis kev siv hluav taws xob ntau dua piv rau cov pa CRT (Cathode Ray Tube) lossis LCD (Liquid Crystal Display) cov ntxaij vab tshaus.
LED (Lub teeb Emitting Diode)
LED yog hom diode, uas tuaj yeem tawm lub teeb thaum ua haujlwm. Txij li thaum diode muaj ob hom P-hom thiab N-hom inorganic semiconductor txheej (piv txwv li: Si, Ge), ob qho tib si 'electrons' thiab 'qhov' (cov neeg nqa khoom zoo tam sim no) koom nrog hauv kev coj ua. Yog li ntawd, cov txheej txheem 'recombination' (ib qho tsis zoo electrons koom nrog lub qhov zoo) tshwm sim, tso qee lub zog. LED yog tsim nyob rau hauv ib txoj kev uas, cov energies raug tso tawm nyob rau hauv cov nqe lus ntawm photons (lub teeb hais) ntawm nyiam xim.
Yog li ntawd, LED yog lub teeb ci, thiab nws muaj ntau yam zoo xws li kev siv hluav taws xob, kev ua haujlwm ntev, me me thiab lwm yam. Tam sim no ib puag ncig tus phooj ywg LED teeb pom kev zoo tau tsim, thiab lawv tau siv rau hauv cov khoom niaj hnub.
OLED (Organic Lub Teeb Emitting Diode)
OLEDs yog ua los ntawm cov txheej txheem ntawm cov organic semiconductors. Cov txheej txheem organic no feem ntau muab tso rau ntawm cathode thiab anode (OLED kuj yog 2 lub davhlau ya nyob twg semiconductor li LED). Cov txheej txheem electron-qhov recombination ua rau lub teeb emission. Feem ntau muaj ob txheej hu ua emissive txheej thiab conductive txheej. Emission ntawm hluav taws xob tshwm sim ntawm emissive txheej.
Dab tsi yog qhov txawv ntawm LED thiab OLED?
1. OLEDs muaj cov khoom siv organic thiab LEDs yog ua los ntawm cov khoom siv hluav taws xob tsis zoo.
2. OLED kuj yog ib hom LED.
3. OLEDs cov duab tau cia siab tias yuav kim dua yav tom ntej.
4. OLEDs tau hais tias yuav siv zog ntau dua li ib txwm LEDs.
