LED teeb pom kev zoo

Nov 13, 2017

LED backlight LED lub teeb ci li lub nrig. Lub teeb-emitting diode yog tsim los ntawm ob peb txheej txheej ntawm doped semiconductor khoom nrog ib txheej ntawm tshaj electrons thiab lwm txheej ntawm electrons tsis muaj electrons rau daim qhov nrog zoo tsub. Tam sim no dhau los ntawm kev ua haujlwm, electrons thiab qhov sib txuas ua ke, Lub zog tso tawm raws li pom hluav taws xob. Light-emitting diodes muaj ntau lub teeb-emitting yam ntxwv tau los ntawm kev siv cov khoom sib txawv ntawm semiconductor.

LED teeb pom kev zoo tshuab muaj qhov muaj nuj nqi zoo, qhov ntau heev hauv cov khoom tsim tau. Tam sim no dhau CCFL (Txias Cathode Backlight) technology vim nws qhov kev txwv spectrum, cov xim gamut ntau yog muaj ntau dua kev txwv, qhov kev kawm zoo tshaj plaws tsuas yog 70% ntawm NTSC xim gamut, cov nyhuv dua siab yuav tau them kim kim kim kim. Txawm li cas los xij, kev siv ntawm lub teeb ci ntsa iab yog qhov txawv txav, vim hais tias cov LED (lub teeb emitting diode) npog lub dav spectrum ntawm lub teeb, ntau lub teeb nrig, qhov xim zoo li gamut ntau yam tau yooj yim txog 100% mus 130%, tsis zoo li cov txwm CCFL backlight Qhov xim tib xim 30%. Yog li ntawd, cov xim ntawm LED backlight monitor yog ntau tshaj, cov duab paub meej, hloov xim ntau dua qub.
