LED backlight ncaj qha
Thaum siv cov teeb pom kev zoo LED backlights hauv cov LCDs nruab nrab thiab loj, qhov hnyav thiab tus nqi ntawm lub phaj qhia teeb pom kev zoo yuav nce ntxiv nrog rau qhov loj me, thiab qhov ci ntsa iab thiab kev sib xws ntawm lub teeb ci tsis zoo tagnrho. Lub vaj huam sib luag teeb pom kev zoo tsis tuaj yeem paub txog kev tswj hwm thaj tsam ntawm LCD TV, tab sis tsuas yog tuaj yeem paub txog kev tsaus ntuj ib-seem yooj yim, thaum lub teeb pom kev zoo LED backlight ua haujlwm zoo dua thiab tuaj yeem paub txog kev tswj hwm thaj tsam ntawm LCD TV. Cov txheej txheem backlight ncaj qha yog... -
LED backlight uas ci ntsa iab
LED backlight hais txog kev siv LEDs (lub teeb emitting diodes) ua lub teeb backlight ntawm cov kua siv lead ua zaub, thaum LED backlight zaub tsuas yog lub teeb backlight ntawm cov kua siv lead ua zaub los ntawm CCFL txias lub raj teeb (zoo ib yam li cov teeb fluorescent) mus rau LED (lub teeb emitting diode). Lub hauv paus ntsiab lus ntawm cov kua siv lead ua zaub tuaj yeem nkag siab yooj yim tias qhov hluav taws xob sab nraud siv los cuam tshuam cov kua siv lead ua zaub yuav thaiv qhov pom tseeb ntawm t... -
Mini LED
Mini LED thev naus laus zis yog ib qho thev naus laus zis tshiab rau kev tso saib. Ntxiv rau kev siv rau hauv TVs, Mini LED thev naus laus zis kuj tseem yuav tshwm sim rau ntawm cov khoom siv ntse xws li ntsiav tshuaj, xov tooj ntawm tes, thiab cov moos yav tom ntej. Yog li ntawd, cov thev naus laus zis tshiab no tsim nyog tau txais kev saib xyuas. Mini LED thev naus laus zis tuaj yeem suav tias yog qhov hloov kho dua tshiab ntawm cov vijtsam LCD ib txwm muaj, uas tuaj yeem txhim kho qhov sib piv thiab txhim kho kev ua haujlwm ntawm cov duab.
