Thaum xaiv cov zaub tshiab, txawm tias rau TV, saib, lossis digital signage, ib qho ntawm cov teeb meem feem ntau yog kev txiav txim siab ntawm LED thiab LCD technology. Ob lo lus feem ntau ntsib hauv ntiaj teb tech, tab sis lawv txhais li cas tiag? Kev nkag siab qhov sib txawv ntawm LED thiab LCD tuaj yeem pab koj txiav txim siab paub txog cov cuab yeej siv twg zoo tshaj plaws rau koj cov kev xav tau.
Nkag siab txog LED thiab LCD thev naus laus zis
Yuav pib, nws yog ib qho tseem ceeb kom paub meej tias "LED" (Lub Teeb Emitting Diode) thiab "LCD" (Liquid Crystal Display) tsis yog cov thev naus laus zis sib txawv. Qhov tseeb, lawv feem ntau ua haujlwm ua ke. Nov yog li cas:
- LCD: Ib qho LCD zaub siv cov kua siv lead ua kua los tswj lub teeb thiab tsim cov duab ntawm lub vijtsam. Txawm li cas los xij, cov crystals no tsis tsim lub teeb ntawm lawv tus kheej. Hloov chaw, lawv xav tau lub teeb rov qab los ua kom pom qhov pom.
- LED: LED yog hais txog hom backlighting siv hauv LCD zaub. Traditional LCDs siv CCFL (txias cathode fluorescent teeb) rau backlight, whereas LED zaub siv lub teeb-emitting diodes. LED backlighting no yog dab tsi muab LED qhia lawv lub npe.
Hauv qhov tseeb, "LED zaub" yog qhov tseeb "LED-backlit LCD zaub." Qhov txawv yog nyob rau hauv hom backlighting siv.
Qhov txawv tseem ceeb ntawm LED thiab LCD
- Backlighting Technology:
- LCD (CCFL backlight): Yav dhau los LCDs tau siv CCFLs, uas muab cov teeb pom kev zoo sib xws thoob plaws lub vijtsam tab sis tsis tshua muaj zog thiab ntau dua.
- LED (LED backlighting): Niaj hnub nimno LCDs nrog LED backlighting muaj ntau lub teeb pom kev zoo hauv cheeb tsam, ua kom zoo dua qhov sib piv thiab lub zog txuag. LEDs tuaj yeem teeb tsa hauv ntug-lit lossis tag nrho-array configurations, tso cai rau kev tswj kom meej dua qhov ci.
- Duab Zoo:
- LCD: Tus qauv CCFL-backlit LCDs muab qhov ci ntsa iab zoo tab sis feem ntau tawm tsam nrog cov xim dub thiab qhov sib txawv siab vim qhov kev txwv ntawm lub teeb pom kev zoo.
- LED: LED-backlit displays muab qhov zoo sib xws, sib sib zog nqus dub, thiab cov xim zoo nkauj dua, ua tsaug rau qhov muaj peev xwm ua kom dim lossis ci ntsa iab rau qee qhov chaw ntawm lub vijtsam (cov txheej txheem hu ua lub zos dimming).
- Zog Efficiency:
- LCD: CCFL-backlit qhia siv lub zog ntau dua vim lawv cov teeb pom kev tsis zoo thiab tsis muaj peev xwm kho qhov ci ntsa iab.
- LED: LED cov lus pom muaj zog ntau dua, vim lawv siv lub zog tsawg dua thiab tuaj yeem kho qhov ci ntsa iab raws li cov ntsiab lus tau tshwm sim.
- Slimmer Design:
- LCD: Traditional CCFL-backlit LCDs yog bulkier vim yog lub teeb rov qab loj dua.
- LED: Lub compact loj ntawm LEDs tso cai rau nyias, ntau lub teeb pom kev zoo, ua rau lawv zoo tagnrho rau niaj hnub, sleek tsim.
- Xim Accuracy thiab Brightness:
- LCD: CCFL-backlit zaub feem ntau muab cov xim zoo, tab sis yuav poob qis hauv kev xa cov duab ci ntsa iab.
- LED: LED qhia tau zoo ntawm cov xim raug thiab ci ntsa iab, tshwj xeeb tshaj yog cov thev naus laus zis zoo li quantum dots lossis tag nrho-array backlighting.
- Kev ua neej nyob:
- LCD: CCFL-backlit displays muaj lub neej luv luv vim qhov maj mam dimming ntawm cov hlab fluorescent dhau sijhawm.
- LED: LED-backlit zaub muaj lub neej ntev dua, vim tias LEDs muaj zog dua thiab tswj lawv qhov ci rau lub sijhawm ntev.
Kev siv thiab tsim nyog
- Tsev Lom Zem: Rau cov neeg nrhiav kev pom zoo nrog cov xim nplua nuj thiab sib sib zog nqus sib sib zog nqus, LED-backlit zaub yog qhov kev xaiv. Lawv tau siv dav hauv cov TV niaj hnub thiab cov saib, muab kev pom zoo rau kev ua yeeb yaj kiab, gaming, thiab streaming.
- Kev siv tshaj lij: Nyob rau hauv ib puag ncig uas cov xim raug thiab qhov ci ntsa iab yog qhov tseem ceeb, xws li hauv kev tsim duab, kev kho video, thiab digital signage, LED zaub muab qhov tseeb thiab meej xav tau.
- Kev xaiv nyiaj txiag-phooj ywg: Yog tias tus nqi yog qhov kev txhawj xeeb tseem ceeb, ib txwm siv CCFL-backlit LCD cov lus tseem tuaj yeem pom ntawm tus nqi qis dua, txawm hais tias lawv qhov kev ua tau zoo yuav tsis phim cov qauv LED-backlit.
Cov ntsiab lus: Qhov twg zoo dua?
Kev xaiv ntawm LED thiab LCD feem ntau nyob ntawm seb koj muaj nuj nqis npaum li cas hauv cov zaub. Yog tias koj saib xyuas cov duab zoo tshaj plaws, kev siv hluav taws xob zoo, thiab kev tsim qauv niaj hnub, LED-backlit zaub yog qhov tseeb yeej. Cov lus qhia no muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb: kev ua tau zoo ntawm LCD technology ua ke nrog qhov zoo ntawm LED backlighting.
Txawm li cas los xij, yog tias koj nyob ntawm pob nyiaj siv nruj lossis muaj cov cai tshwj xeeb uas tsis xav tau cov thev naus laus zis tshiab, lub LCD qub nrog CCFL backlighting yuav txaus. Uas tau hais tias, raws li thev naus laus zis nce qib, LED cov duab tau dhau los siv tau thiab pheej yig dua, ua rau lawv txoj kev xaiv mus rau feem ntau cov neeg siv khoom thiab cov kws tshaj lij.
Hauv kev sib ntaus sib tua ntawm LED vs LCD, tus yeej tiag tiag yog tus saib, uas tau txais txiaj ntsig los ntawm kev txhim kho qhov pom kev zoo uas tau tsav los ntawm cov thev naus laus zis tshiab.
