Dab tsi yog qhov txawv ntawm LED screen thiab LCD screen?

2020/12/22

Ua ntej, "Dab tsi yog qhov sib txawv ntawm LED npo thiab lub vijtsam LCD?

Hauv LCD TV, LED npo thiab LCD npo yog qhov tseeb tib lub ntsiab lus, ob qho tib si txhais tau tias yog LCD npo, thiab LED npo yog lub npe tsis raug, LCD yog qhov tseeb raug ntawm LCD TV screen.

Vim li cas thiaj muaj lub npe tsis raug rau LED cov ntxaij vab tshaus?

Ua ntej tshaj plaws, kev nkag siab luv luv ntawm LCD qauv qauv, ntawm no peb tham txog cov lus taw qhia yooj yim:

LCD TV screen feem ntau yog muaj li ntawm LCD tso saib iav vaj huam sib luag npog cov backlight qhov chaw

Raws li koj tuaj yeem pom, lub teeb lub teeb yog feem ntau teeb pom kev zoo los ntawm lub teeb pom kev nyob rau sab nraum qab ntawm lub LCD screen, uas siv los ua CCFL (txias cathode fluorescent teeb), tab sis txij li tau hloov kho nrog LED hlaws .Switching rau LED ua qhov nraub qaum lub teeb ntawm LCD TV tuaj yeem ua rau daim duab zoo dua thiab lub neej ntev dua. Lub vaj huam sib luag npo kuj tseem tuaj yeem ua kom pom tseeb dua thiab cov txheej txheem tsim khoom yog qhov ntau dua ib puag ncig, tsis zoo li cov pa phem ntawm cov teeb roj fluorescent.

Yog li cov ntsiab lus ntawm LED teeb ua LCD rov qab lub teeb pom kev zoo yog qhov kev xaiv zoo dua, tom qab ob peb xyoos dhau los tshaj tawm LED backlight ntawm kua siv lead ua TV, kev lag luam lub sijhawm yuav dhau los ua "LED TV", uas yog vim li cas rau kev tsim cov lus yuam kev " LED npo ", Kuv vam tias koj tsis txhob ua txhaum ntxiv, LCD yog LCD TV, LED tsuas yog rov qab lub teeb ua kua siv lead ua TV, tam sim no yuav luag LCD TV yog LED rov qab.

Tseem muaj ntau qib micro-LED thev naus laus zis, uas txo LED hlaws dai rau qib micron. Txhua lub teeb me me ntawm LED hlaws yog pixel, thiab lub vaj huam sib luag yog tsim los ntawm cov micron LED hlaws, zoo ib yam li kev tsim kho ntawm OLED TVS hnub no.OLED yog cov organic teeb pom kev zoo, uas siv cov micro-LED thev naus laus zis ntawm inorganic teeb-emitting diode. ua kom TV TV. Nws muaj lub teeb ci siab dua, lub neej ntev dua, kev ua kom zoo dua luminous thiab lub zog txuag ntau dua OLED. Kuv ntseeg tias peb yuav pom cov khoom lag luam ntau hauv cov khoom lag luam zoo no ze rau yav tom ntej.
