1. Dab tsi yog LED, LCD?
LED sawv rau lub teeb-emitting diode, ib qho khoom siv semiconductor ua los ntawm cov tebchaw muaj cov ntsiab lus zoo li gallium (GA), phosphorus (p), thiab nitrogen (n). Thaum cov tshuab hluav taws xob ua kom haum nrog qhov, lawv emit pom lub teeb, ua raws li kev siv hluav taws xob ntau ntawm kev hloov lub teeb hluav taws xob. LEDs tau siv dav siv nyob rau hauv cov lus qhia thiab teeb pom kev zoo.
LCD, lossis ua kua siv lead ua cov zaub, yog ib lub sijhawm dav rau cov khoom siv thev naus laus zis. Ua kua muaju lawv tus kheej tsis emit teeb thiab xav tau ib lub teeb ci rau taws rau lawv, zoo li kev tshaj tawm lub thawv.
Tsuas yog muab, LCD thiab cov ntxaij siv ob qho sib txawv ntawm cov khoom siv thev naus laus zis. LCD cov ntxaij yog tsim cov kua muaju, thaum cov ntxaij vab tshaus coj ntawm lub teeb-emitting diodes.
2. Qhov sib txawv ntawm LED thiab LCD zaub
Qhov txawv 1: Txoj Kev Ua Haujlwm
LEDs yog semiconductor lub teeb-emitting diodes. LED Beads yog miniaturized rau micron qib, nrog rau txhua tus me me LED Bead ua raws li pixel. Vaj huam sib luag ntsuam xyuas tau ncaj qha ntawm cov micron coj mus xoo hluav taws xob. Ntawm qhov tod tes, LCD npo yog qhov tseem ceeb ua kua siv lead ua kua. Nws lub ntsiab hauj lwm ua haujlwm tseem ceeb muaj cov kua siv roj teeb ua ke nrog cov hluav taws xob, hauv thaj chaw, ua ke nrog lub backlight, kom tsim cov duab.
Qhov sib txawv 2: ci ci
Cov lus teb ceev ntawm ib qho LED zaub caij yog 1,000 zaus sai dua li LCD. Qhov no muab LED qhia txog qhov muaj txiaj ntsig tseem ceeb hauv kev ci ntsa iab, ua rau pom meej meej pom txawm tias lub teeb ci ntsa iab. Txawm li cas los xij, lub teeb ci ntau dua yog tsis yog ib qho zoo dua; Thaum zoo dua ci ntsa iab yog qhov zoo dua rau kev saib deb, nws tuaj yeem ci ntsa iab rau kev saib ze. LCD cov ntxaij vab tshaus emit teeb los ntawm kev ua kom pom kev zoo, ua kom lub ntsej muag ci ntsa iab thiab tsawg dua ntawm lub qhov muag, tab sis nyuaj rau pom lub teeb ci ntsa iab. Yog li ntawd, rau cov ntxaij vab tshaus uas nyob deb, cov ntxaij vab tshaus tau haum ntau, thaum cov ntxaij vab tshaus ntau dua, thaum lub sijhawm LCD zoo dua rau kev saib ze.
Qhov sib txawv 3: xim zaub
Nyob rau hauv cov nqe lus ntawm cov xim zoo, lcd cov ntxaij muaj cov xim zoo dua thiab cov duab nplua nuj, tshwj xeeb tshaj yog hauv grayscale rendering.
Qhov txawv 4: Kev Siv Fais Fab
Lub zog siv kev sib piv ntawm coj mus rau LCD yog kwv yees li 1:10. Qhov no vim tias LCDs tig tag nrho Backlight txheej rau lossis tawm; Nyob rau hauv kev sib piv, leds yuav lub teeb tau tsuas yog cov pixels tshwj xeeb, ua rau lawv muaj zog ntau.
Qhov sib txawv 5: Tshaj Tawm
Ua tsaug rau tus kheej-illuminating xwm ntawm LEDs, lawv muab kev sib piv zoo dua piv rau LCDs. Lub xub ntiag ntawm backlight nyob rau hauv lcds ua rau nws nyuaj rau ua kom tiav cov xim dub.
Qhov sib txawv 6: Refresh Rates
Tus nqi kho tshiab ntawm LED screen yog siab dua vim tias nws teb cov video nrawm dua, thaum lub vijtsam LCD vim yog cov lus teb qeeb.
Qhov sib txawv 7: Saib cov ces kaum
LED screen muaj qhov chaw dav dav saib lub kaum, vim tias lub teeb ci ntsa iab yog qhov zoo dua qub, LCD Screen yog qhov zoo heev, cov duab zoo yuav tsis zoo.
Qhov sib txawv 8: Lifespan
LED Screen lub neej ntev dua, vim tias nws lub teeb ci ntsa iab yog ruaj khov thiab tsis yooj yim rau lub hnub nyoog, thaum lub sij hawm LCD cov ntaub ntawv rho tawm yuav maj mam ua rau lub sijhawm.
3. Qhov twg zoo dua, LED lossis LCD?
LCDS Siv cov ntaub ntawv inorganic, uas muaj hnub nyoog maj mam thiab muaj lub neej ntev. LEDs, ntawm qhov tod tes, siv cov ntaub ntawv organic, yog li lawv lub neej muaj luv dua li ntawm LCD ntxaij.
Yog li, cov ntxaij vab tshaus lcd, muaj cov kua muaju ua kua, muaj lub neej ntev dua tab sis haus lub zog ntau dua vim txhua qhov-ntawm / tag nrho-tawm backlight. Cov ntxaij vab tshaus LED, muaj ntawm lub teeb ci ntsa iab
Yog tias koj xav tau tob dua Leran LED kev paub kev lag luam,Tiv Tauj Peb Tam Sim Nokom tau txais ntau dua
