Lub zog hluav taws xob tsawg tsawg txhais tau tias kev siv lub teeb ci, lub teeb ci ntsa iab (LED) yog siv hauv ntau cov khoom siv hluav taws xob uas nquag siv hauv tsev nruab nrab. LED sib txawv ntawm cov txheej txheem hluav taws xob teeb pom nyob rau hauv feem ntau cov tsev vim nws siv cov khoom siv hluav taws xob hluav taws xob ua hluav taws xob los tsim ua lub teeb hloov chaw siv hluav taws xob. Yuav luag ib daim ntawv ntawm lub teeb pom kev zoo, LED thev naus laus zis yog siv hauv koos pij tawj, TV, chaw taws teeb, thiab teeb nyem, xws li hauv cov paib, teeb pom kev zoo, thiab teeb pom kev zoo thiab theem teeb pom kev zoo.
Hauv chav LED teeb, hluav taws xob muaj hluav taws xob ua rau lub semiconductor muaj nyob hauv lub qhov muag LED rau emit lub teeb. Siv los tsim cov xim xiav lossis dawb lub teeb, nitride yog ib qho ntawm cov khoom siv hluav taws xob feem ntau tau thov hauv LED modules. Cov thev naus laus zis LED yog siv hauv cov TV tshiab tshiab, qhov uas nws yog qhov hloov rau cathode ray tube (CRT) teeb pom kev zoo uas tau tshwm sim dhau los. Hauv LED TV, pawg ntawm LED diodes tau muab faib ua cov phiaj uas ua rau lub teeb thiab xim rau daim duab ntawm lub vijtsam. Cov lag luam muag lev nrog LED thev naus laus zis yog lub zog ntau dua, yuag dua hauv cov ntawv me, qhov hnyav dua, thiab ib puag ncig zoo dua hauv kev muab pov tseg dua li qub CRT TV, tab sis lawv kuj tseem kim dua.
