Qhov txawv ntawm Lcd thiab Led yog dab tsi?

LCD thiab LED yog ob qho tib si cov yees duab nrov siv hauv cov khoom siv hluav taws xob niaj hnub, xws li TVs, khoos phis tawj saib, thiab xov tooj ntawm tes. LCD stands rau Liquid Crystal Display, thaum LED stands rau lub teeb Emitting Diode. Txawm hais tias ob qho tib si thev naus laus zis tau siv los ua kom pom kev ua tau zoo, muaj qhov sib txawv tseem ceeb ntawm ob.

Qhov sib txawv ntawm LCD thiab LED yog qhov uas lawv ua haujlwm. LCDs ua haujlwm los ntawm kev tswj lub teeb hla dhau los ntawm cov kua siv lead ua kua txheej sandwiched ntawm ob daim iav. Cov txheej txheem no suav nrog kev siv cov raj fluorescent lossis txias cathode fluorescent teeb (CCFLs) los teeb pom kev.

Hauv qhov sib piv, LEDs yog cov khoom siv semiconductor uas tawm lub teeb thaum muaj hluav taws xob ntws los ntawm lawv. Txoj kev no, lub teeb-emitting diodes ua haujlwm raws li ob qho tib si backlight thiab pixels. Li no, LED zaub tshuab siv lub zog tsawg dua thiab muaj cov xim gamut ntau dua li LCD.

Lwm qhov sib txawv tseem ceeb ntawm LCD thiab LED yog txoj kev lawv rov qab. Raws li tau hais dhau los, LCDs xav tau lub teeb pom kev sib cais los teeb lub vijtsam. Cov txheej txheem no tshwm sim tom qab lossis hauv qab txheej ntawm cov kua siv lead ua kua illuminated los ntawm ib qho thiab tsuas yog ib qho xim ntawm lub teeb. Txoj hauv kev no ua rau muaj kev vibrancy tsawg dua thiab qhov sib txawv ntawm qhov kev ua tau zoo.

Ntawm qhov tod tes, LEDs yog tus kheej-teeb, backlit zaub. Txhua diode qhia pixelated xim thiab brightness specs, uas tag nrho muaj xws li contrast thiab xim fidelity ntawm cov zaub. Qhov kev teeb tsa no txhais tau hais tias LEDs tuaj yeem qhib thiab tawm sai dua, ua rau LED zaub tshuab tsim nyog rau cov duab nrawm ntawm TV thiab rau cov khoom siv ua si.

Thaum nws los txog rau kev siv hluav taws xob, LED cov lus pom muaj zog ntau dua li lawv cov khoom siv LCD, siv txog li 40% tsawg zog. Qhov kev siv hluav taws xob no ua rau LED qhia ntau dua eco-friendly thiab raug nqi. LED teeb tsis yog tsuas yog zoo ntawm tus nqi tab sis kuj yog qhov tsawg tshaj plaws ib puag ncig kev cuam tshuam cov cuab yeej siv vim tias lawv siv zog tsawg dua li lwm cov khoom siv teeb pom kev zoo thiab cov khoom siv.

Hauv kev xaus, thaum lawv qhia qee qhov sib xws, LED thiab LCD thev naus laus zis muaj qhov sib txawv tseem ceeb. LED thev naus laus zis muaj zog ntau dua, muaj xim ntau dua, thiab muaj qhov sib piv zoo dua li LCD. Hauv qhov sib piv, LCD thev naus laus zis yog pheej yig dua thiab nrov nrog OEM cov cuab yeej tsim khoom thiab cov ntsiab lus tsim tawm. Thaum kawg, cov neeg yuav khoom yuav tsum txiav txim siab seb qhov kev xaiv twg haum rau lawv cov kev xav tau zoo tshaj plaws los ntawm kev txiav txim siab lub hom phiaj ntawm lub cuab yeej, xim tsis pom kev, nyiam, thiab lub hom phiaj ntawm kev siv hluav taws xob.
