Dab tsi yog xya ntu LED?
Ib tug xya-ntu LED yog ib qho digital zaub module tshwj xeeb los tso saib cov ntaub ntawv xov xwm.
Lub teeb-emitting diodes (LEDs) teeb tsa hauv cov duab ntawm cov lej muab cov duab pom yooj yim.
Lawv qee zaum hu ua" xya ntu qhia" los yog" xya ntu ntsuas."
Cov npe ntawm xya ntu LED qhov chaw
Qhov chaw ntawm xya ntu LED yog raws li hauv qab no:
Lub teeb-emitting Cheebtsam (a–g): Ntu (Seg)
Dot light-emitting Cheebtsam: Decimal point (DP)
Lub npe dav dav rau xya ntu a–g: Tus lej (Dig)
Xya-seg LED Circuit Court configuration
LED zaub cov khoom siv muaj ob hom Circuit Court: ntau anode thiab ntau cathode.
Common anode: thaum tus pin hom yog qhov zoo
Common cathode: thaum tus pin hom tsis zoo
