Hais txog kev txhim kho yav tom ntej ntawm LCD thev naus laus zis, tau muaj kev sib cav ntau hauv kev lag luam. Txawm li cas los xij, nrog kev nrawm ntawm cov khoom hloov khoom dua tshiab, ntau thiab ntau tus neeg lean mus hloov LCDs nrogOLEDs. Nws yog ib qho tseem ceeb kom paub meej tias LCDs tsis zoo ib yam li LEDs. LED TV technology yog dab tsi? LED tsis yog ib qho kev ywj pheej TV tso saib thev naus laus zis tab sis yog LCD TV nrog LED backlight, nrog rau cov thev naus laus zis tseem ceeb yog LCD.
Vim muaj kev nce qib hauv cov kua siv lead ua vaj huam sib luag txiav thev naus laus zis, cov khoom siv me me ntawm lub vijtsam yog feem ntau yog thawj coj los siv cov thev naus laus zis tshiab. Yog li ntawd, kev txhim kho tag nrho ntawm cov khoom siv ua kua siv lead ua yav tom ntej tuaj yeem pom nyob rau hauv cov duab me me. Raws li qhov teeb meem kev lag luam tam sim no, Samsung's AMOLED tau dav lees paub tias yog lub cim tom ntej tso saib thev naus laus zis nrog kev ua tau zoo dua. Lub caij no, cov lus xaiv IGZO zaub thev naus laus zis, uas Apple yuav tsum tau txais yuav hauv iPhones yav tom ntej, kuj tseem ua rau muaj kev cia siab. Tab sis dab tsi yog qhov txawv ntawm ob lub thev naus laus zis no? Lawv qhov zoo thiab qhov tsis zoo yog dab tsi?
Cia peb pib nrog AMOLED. Lub npe tag nrho yog Active Matrix Organic Light Emitting Diode, uas yog hom OLED (Organic Light Emitting Display) thev naus laus zis. OLED suav nrog lub teeb emissions los ntawm cov cab kuj txhaj tshuaj thiab recombination, tsav los ntawm ib tug hluav taws xob teb nyob rau hauv cov organic semiconductor thiab luminescent cov ntaub ntawv. Lub tshuab siv ITO pob tshab electrodes thiab hlau electrodes raws li cov cuab yeej anode thiab cathode. Thaum siv qee qhov hluav taws xob, cov khoom siv hluav taws xob thiab qhov yog txhaj los ntawm cathode thiab anode mus rau hauv cov khoom siv hluav taws xob thiab qhov chaw thauj cov khaubncaws sab nraud povtseg. Cov cab kuj tsiv mus rau lub teeb-emitting txheej, qhov chaw uas lawv ntsib thiab tsim excitons. Cov excitons excite light-emitting molecules, uas emit pom lub teeb los ntawm radiative so.
AMOLED muaj ntau qhov zoo, suav nrog cov lus teb nrawm dua, qhov sib txawv dua, thiab qhov pom dav dua. Tam sim no, Samsung Electronics muab qhov tseem ceeb rau qhov kev siv thev naus laus zis no, suav txog 99% ntawm kev ua lag luam.
