1. LCD
LCD yog lub npe tag nrho ntawm Liquid Crystal Display, uas feem ntau suav nrog ntau hom kua siv lead ua kua xws li TFT, UFB, TFD, thiab STN, yog cov cuab yeej siv dav tshaj plaws.
Cov qauv ntawm LCD yog muab cov kua siv lead ua kua cell tso rau hauv ob qho tib si iav substrates, TFT (thin film transistor) yog teem rau ntawm lub khob ntawm lub substrate, thiab cov xim lim yog teem rau ntawm lub khob ntawm lub substrate, thiab Cov kua siv lead ua kua molecules yog tswj los ntawm lub teeb liab thiab qhov hluav taws xob hloov pauv ntawm TFT Tig qhov kev taw qhia, thiaj li tswj xyuas seb lub teeb pom kev zoo ntawm txhua pixel tawm los yog tsis ua kom tiav lub hom phiaj tso saib.
LCD yog ib yam khoom nruab nrab ntawm lub xeev thiab lub xeev ua kua. Nws tsis tuaj yeem tawm lub teeb los ntawm nws tus kheej, thiab nws xav tau lub teeb ci ntxiv. Yog li ntawd, tus naj npawb ntawm cov teeb muaj feem xyuam rau qhov ci ntsa iab ntawm cov kua siv lead ua kua.
2. LED
LED (Lub Teeb-emitting diode) npo, qhov tseeb, cov duab ntawm cov lus qhia no tseem tsim los ntawm cov kua siv lead ua kua, thiab lub teeb-emitting diodes tsuas yog siv los ua lub teeb ci. Technically, lawv tseem yog LCD zaub, lossis LED-backlit LCD zaub.
Cov kua siv lead ua kua (LCD) TV nrog lub vijtsam LED muaj qhov zoo ntawm qhov me me, kev siv hluav taws xob tsawg, lub neej ntev, tsis muaj nqi, siab ci, pom dav thiab siab refresh npaum li cas. Qhov tsis zoo yog tias cov xim ua haujlwm tsis zoo, tshwj xeeb tshaj yog thaum lub vijtsam LCD yog folded. qhov twg cov xim sib txawv yog pom tseeb dua.
3. OLED
OLED (Organic Light-Emitting Diode) Organic Light Emitting Diode.OLEDs tuaj yeem tso lub teeb los ntawm lawv tus kheej, yog li tsis tas yuav muaj lub teeb rov qab. LEDs siv cov ntaub ntawv hlau, thaum OLEDs siv cov khoom siv organic. Lawv tuaj yeem tawm lub teeb yam tsis muaj teeb pom kev zoo, thiab qhov sib piv zoo dua.
Cov ntaub ntawv organic phosphorous siv hauv OLED yog qhov tsis yooj yim, thiab qhov ci yuav txo qis tom qab siv mus ntev. Tau kawg, qhov ci ntawm LCD yuav maj mam txo qis tom qab siv mus ntev.
4. QLED
QLED, luv luv rau Quantum Dot Lub Teeb Emitting Diodes, yog lub tshuab hluav taws xob rau tus kheej uas tsis tas yuav muaj teeb pom kev ntxiv.
Quantum Dots yog qee qhov me me semiconductor nanocrystals uas tsis tuaj yeem pom ntawm qhov muag liab qab, thiab yog cov khoom uas muaj qhov me me ntawm tsawg dua 10 nanometers. Quantum dots muaj qhov tshwj xeeb: thaum twg lawv raug txhawb los ntawm lub teeb lossis hluav taws xob, lawv tawm xim xim. Cov xim ntawm lub teeb yog txiav txim siab los ntawm cov khoom siv thiab qhov loj ntawm quantum dot, thiab nws qhov zaus tuaj yeem hloov pauv los ntawm kev hloov qhov loj ntawm quantum dot. , cov duab thiab cov khoom siv kom raug kho rau ntau yam kev siv.
Cov qauv ntawm QLED zoo ib yam li OLED thev naus laus zis, qhov sib txawv tseem ceeb yog qhov chaw teeb pom kev zoo ntawm QLED yog tsim los ntawm quantum dots. Nws cov qauv yog tias electrons thiab qhov ntawm ob sab converge nyob rau hauv quantum dot txheej los ua Exciton, thiab emit lub teeb los ntawm recombination ntawm photons.
