Cov phab ntsa yeeb yaj kiab thiab cov ntxaij vab tshaus LED siv cov khoom siv sib txawv. Cov thev naus laus zis hauv qab no txiav txim siab feem ntau ntawm qhov zoo thiab qhov tsis zoo ntawm cov duab no.

Cov phab ntsa yees duab siv LCD thev naus laus zis, thaum lub vijtsam LED siv cov thev naus laus zis LED.

LCD, los yog kua siv lead ua zaub, yog ib qho cuab yeej siv ib txheej ntawm cov khoom siv ua kua siv lead ua sandwiched ntawm ob lub electrodes ntawm iav substrates. Raws li nws tsis tuaj yeem tawm lub teeb ntawm nws tus kheej, nws xav tau lub teeb rov qab.LCDs tau nquag siv hauv TV hauv tsev, saib lub computer, thiab cov cim digital. Lawv tau qhia ntau xyoo dhau los los hloov CRT cov lus qhia, uas yog tuab dua thiab ntau dua.

Hauv qhov sib piv, LED thev naus laus zis siv lub teeb-emitting diodes uas tuaj yeem tawm lub teeb ntawm nws tus kheej. Vim tias LED thev naus laus zis tsis vam khom lub teeb pom kev zoo, nws tuaj yeem ua tiav qib dub zoo meej los ntawm kev xa tawm yooj yim. Yog li ntawd, LED tuaj yeem tsim cov duab nrog qhov sib piv siab dua.

LED screen outperforms lub LCD npo nyob rau hauv cov nqe lus ntawm cov zaub brightness, nrog ib tug ntau dua nit nqi. Ib nit yog ib chav ntsuas uas siv los sawv cev qhov ci.

Zuag qhia tag nrho, lub vijtsam LED ua tau zoo hauv qhov pom kev zoo, suav nrog qib dub, ci ntsa iab, xim raug, thiab qhov sib piv piv, ua rau nws pom meej meej ntawm phab ntsa video.
