Lub ntsiab lus ntawm LED Backlight
Oct 01, 2022| Suav txhais ntawm backlight yog "lub teeb tsis tuaj yeem ncaj qha illuminated" lossis "tsis txhob cuam tshuam lub teeb".
Hauv kev lag luam hluav taws xob, backlighting yog ib hom teeb pom kev zoo uas feem ntau siv rau ntawm cov duab LCD. Qhov sib txawv ntawm hom teeb pom kev zoo thiab lub teeb pem hauv ntej yog qhov teeb pom kev zoo ntawm sab nraub qaum lossis sab nraub qaum, thaum lub teeb pem hauv ntej yog illuminated los ntawm pem hauv ntej raws li lub npe qhia. Lawv tau siv los ua kom pom kev pom hauv qhov chaw qis qis thiab ua kom pom lub computer ci ntsa iab, cov ntxaij vab tshaus LCD, thiab tsim teeb pom kev zoo ib yam li cov duab CRT.
Lub teeb ci tuaj yeem yog lub teeb ci, lub teeb ci hluav taws xob (ELP), lub teeb emitting diode (LED), txias cathode tube (CCFL) thiab lwm yam. Electro-optical panels muab teeb pom kev zoo thoob plaws qhov chaw, thaum lwm lub teeb pom kev zoo siv cov diffusers los muab cov teeb pom kev zoo los ntawm qhov tsis sib xws.
Lub teeb rov qab tuaj yeem yog xim xim, thiab cov kua siv lead ua monochrome feem ntau muaj lub teeb pom kev zoo xws li daj, ntsuab, xiav, thiab dawb. Cov xim xim siv lub teeb dawb dawb vim nws npog lub teeb xim tshaj plaws.
LED backlights yog siv nyob rau hauv me me, pheej yig LCD panels. Nws lub teeb feem ntau yog xim, txawm tias dawb backlighting tau dhau los ua ntau dua. Electro-optical panels feem ntau siv rau ntawm cov lus qhia loj uas qhov teeb pom kev zoo ib yam tseem ceeb. Lub vaj huam sib luag electro-optical yuav tsum tau tsav los ntawm high-voltage alternating tam sim no, uas yog muab los ntawm inverter Circuit Court. Cov hlab ntsha cathode txias yog siv rau hauv cov khoom xws li lub khoos phis tawj saib, uas feem ntau yog xim dawb, uas tseem yuav tsum tau inverters thiab diffusers. Incandescent backlights yog siv thaum lub teeb ci siab xav tau, tab sis muaj qhov tsis zoo uas cov qhov muag teeb pom kev muaj lub neej tsis tshua muaj thiab ua kom muaj cua sov ntau.
