LED vs LCD zaub: Qhov txawv qhov tseem ceeb, qhov zoo, thiab qhov twg zoo dua?

1. LED, LCD yog dab tsi?

LED stands rau lub teeb-Emitting Diode, ib tug semiconductor ntaus ntawv ua los ntawm cov tebchaw muaj xws li Gallium (Ga), Arsenic (As), Phosphorus (P), thiab Nitrogen (N). Thaum cov hluav taws xob sib txuas nrog lub qhov, lawv tawm lub teeb pom kev, ua rau LEDs muaj txiaj ntsig zoo ntawm kev hloov hluav taws xob rau hauv lub teeb lub zog. LEDs tau siv dav hauv cov lus qhia thiab teeb pom kev zoo.

LCD, lossis Liquid Crystal Display, yog ib lo lus dav dav rau cov cuab yeej siv digital. Cov kua siv lead ua kua lawv tus kheej tsis tawm lub teeb thiab xav tau lub teeb rov qab los teeb pom kev zoo, zoo li lub thawv tshaj tawm.

Cias muab tso, LCD thiab LED cov ntxaij vab tshaus siv ob yam khoom siv thev naus laus zis. Cov ntxaij vab tshaus LCD yog tsim los ntawm cov kua siv lead ua kua, thaum cov ntxaij vab tshaus LED yog tsim los ntawm lub teeb-emitting diodes.

2. Qhov txawv ntawm LED thiab LCD zaub

Qhov txawv 1: Txoj Kev Ua Haujlwm

LEDs yog semiconductor lub teeb-emitting diodes. LED hlaws dai me me mus rau qib micron, nrog rau txhua qhov me me LED hlaws ua yeeb yam li pixel. Lub vijtsam vaj huam sib luag yog ncaj qha tsim ntawm cov micron-theem LED hlaws dai. Ntawm qhov tod tes, lub vijtsam LCD yog qhov tseem ceeb ntawm cov kua siv lead ua kua. Nws txoj haujlwm tseem ceeb suav nrog kev txhawb nqa cov kua siv lead ua kua molecules nrog cov hluav taws xob tam sim no los tsim cov dots, kab, thiab qhov chaw, ua ke nrog lub teeb nraub qaum, tsim cov duab.

Qhov txawv 2: Brightness

Cov lus teb ceev ntawm ib qho khoom siv LED yog 1,000 zaus sai dua li ntawm LCD. Qhov no muab LED tso saib qhov zoo dua hauv qhov ci, ua kom pom tseeb txawm tias nyob hauv lub teeb ci. Txawm li cas los xij, qhov ci ntsa iab ntau dua tsis yog qhov zoo dua qub; thaum lub teeb ci siab dua yog qhov zoo dua rau kev pom nyob deb, nws tuaj yeem ua rau pom kev ze. LCD cov ntxaij vab tshaus emit lub teeb los ntawm refracting lub teeb, ua rau lub brightness softer thiab tsawg straining ntawm lub qhov muag, tab sis nyuaj rau saib nyob rau hauv lub teeb ci. Yog li ntawd, rau cov lus qhia nyob deb, LED cov ntxaij vab tshaus yog qhov tsim nyog dua, thaum LCD cov ntxaij vab tshaus zoo dua rau kev pom ze.

Qhov txawv 3: Xim Zaub

Nyob rau hauv cov nqe lus ntawm cov xim zoo, LCD cov ntxaij vab tshaus muaj cov xim zoo dua thiab cov nplua nuj, ntau cov duab zoo nkauj, tshwj xeeb tshaj yog nyob rau hauv greyscale rendering.

Qhov txawv 4: Kev siv hluav taws xob

Lub zog noj piv ntawm LED rau LCD yog kwv yees li 1:10. Qhov no yog vim LCDs tig tag nrho backlight txheej rau lossis tawm; Hauv qhov sib piv, LEDs tuaj yeem teeb pom tsuas yog cov pixels ntawm qhov screen, ua rau lawv siv zog ntau dua.

Qhov txawv 5: Contrast

Ua tsaug rau tus kheej-illuminating xwm ntawm LEDs, lawv muab qhov zoo sib xws piv rau LCDs. Lub xub ntiag ntawm lub teeb rov qab hauv LCDs ua rau nws nyuaj rau ua tiav qhov tseeb dub.

Qhov txawv 6: Refresh tus nqi

Lub refresh npaum li cas ntawm LED screen yog siab dua vim hais tias nws teb sai dua thiab plays video smoothly, thaum LCD npo yuav luag vim qeeb teb.

Qhov txawv 7: Saib cov kaum sab xis

LED npo muaj lub kaum sab xis pom dav dua, vim tias lub teeb pom kev zoo sib xws, tsis hais los ntawm lub kaum ntse ntse, cov duab zoo heev, LCD npo hauv lub kaum ntse ntse, cov duab zoo yuav tsis zoo.

Qhov txawv 8: Lifespan

LED npo lub neej ntev dua, vim hais tias nws lub teeb-emitting diodes yog ruaj thiab tsis yooj yim rau lub hnub nyoog, thaum lub LCD screen backlight system thiab cov khoom siv lead ua kua yuav maj mam degrade lub sij hawm.

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 khoom siv organic, yog li lawv lub neej luv dua li ntawm cov ntxaij vab tshaus LCD.

Yog li ntawd, cov ntxaij vab tshaus LCD, tsim los ntawm cov kua siv lead ua kua, muaj lub neej ntev dua, tab sis siv lub zog ntau dua vim yog tag nrho-on / all-off backlight. LED cov ntxaij vab tshaus, muaj li ntawm lub teeb-emitting diodes, muaj ib tug luv luv lifespan, tab sis txhua pixel yog lub teeb qhov chaw, txo hwj chim noj thaum siv.
