Cov saib niaj hnub no txawv qhov txawv lawv qhov ntev thiab qhov zoo ntawm cov duab sib kis. Txawm li cas los xij, lawv tsis yog txhua yam raws cov kua siv lead ua kua. Cov qauv qhov twg LEDs raug ntsia hu ua LED saib. Feem ntau, LEDs tau siv rau hauv qhov kev tsim ntawm cov ntxaij ntawm cov qauv loj thiab ntxiv-loj.
Dab tsi yog LED saib?
Txhawm rau tsim cov duab hauv cov saib zoo li no, LEDs raug siv, txhua tus uas muaj lub luag haujlwm xa tawm ib lossis ntau xim thiab ua raws li ib tus sub-pixel lossis pixel, feem. Vim tias qhov tseeb ntawm LEDs yog qhov ywj pheej ntawm lub teeb hluav taws xob, lawv tso cai rau koj los tsim ib daim duab nrog ntau lub teeb ci thiab qhov tsis sib xws. Txawm li cas los xij, lawv muaj lwm qhov tsis zoo, uas yog qhov loj me ntawm cov LEDs lawv tus kheej.
Txog tam sim no nws tseem tsis tuaj yeem tsim qhov screen matrix nrog xws li LED me me, uas tib lub sijhawm yuav khaws lawv lub ci ci ci kom thiaj li piv nrog cov kua siv lead ua kua. Thiab tseem, LED tsom kwm tau pom lawv txoj kev lag luam niche, nyob rau hauv uas lawv xyaum tsis tuaj yeem ua tau zoo li no - cov no yog kev tshaj tawm sab nraum zoov thiab cov ntxaij vab tshaus loj siv nyob rau hauv chaw ua si kis las lossis ntawm kev sib tw, thiab lwm yam. Nws yog los ntawm LEDs tias cov ntxaij vab tshaus loj tuaj yeem tsim nrog cov duab zoo heev thiab tus nqi qis. Ntawm qhov kev ncua deb, ntawm qhov kev tshaj tawm, cov ntaub ntawv cov ntxaij vab tshaus thiab cov laug cam raug ntsia, qhov loj ntawm lub diode tsis tseem ceeb, thiab tib neeg lub qhov muag twb pom ib daim duab tsis tseem ceeb, tsis tuaj yeem pom tus tib neeg diodes, txawm tias lawv 5-10 hli hauv txoj kab uas hla.
Cov yam ntxwv ntawm cov qauv ntawm LED saib
Qhov zoo dua ntawm cov diode saib yog qhov uas lawv tsim lub vijtsam tag nrho. Txhawm rau ua qhov no, siv cov pob me dua me me, feem ntau xwm fab. Cov panels muaj, piv txwv, ntawm ib qho sib npaug ntawm 64 diodes ntawm ib sab. Txhua lub vaj huam sib luag muaj nws tus kheej tswj hwm thiab xov xwm tsheb npav, los ntawm kev xa cov duab xa tawm. Cov nyias muaj nyias pawg no twb tau sib sau ua ib qho screen. Hauv qhov no, qhov tseeb, nws tsis muaj teeb meem dab tsi los xij qhov ntev ntawm lub vijtsam yuav yog, qhov tseem ceeb yog tias tus maub los tseem paub qhov no, uas yuav tswj hwm txhua lub sijhawm nyob rau tib lub sijhawm.
Qhov kev tsim no yog lwm qhov zoo ntawm LED tsom teeb. Yog tias ib qho ntawm cov vaj huam sib luag tawg, seem ntawm lub vijtsam txuas ntxiv ua haujlwm zoo li yog tias tsis muaj dab tsi tshwm sim, qhia tau seem ntawm daim duab. Kev kho kuj yog yooj yim: nws tsim nyog hloov qhov sib cais ntawm lub vijtsam puas, thiab nws yuav ua haujlwm zoo li yav dhau los. Qhov kev siv lub neej ntev ntawm LEDs lawv tus kheej kuj cuam tshuam kev cia siab ntawm LED saib.
Nrog rau kev tsim cov khoom siv hluav taws xob thiab cov qauv diode, nws cia siab tias cov neeg soj ntsuam duab yuav hloov los ntawm diode arrays thaum qhov loj me ntawm ib tug neeg pixel sib sau ua ke los ntawm diodes piv rau lub pixel ntawm lub LCD matrix.
Dab tsi ntxiv tuaj yeem txhais tau ntawm lub npe LED saib
Qee zaum, los ntawm kev yuam kev, LED saib yog hu ua cov pa LCD desktop tus saib, nyob rau hauv uas diodes tau siv los ua lub teeb nrig rov qab. Txawm li cas los xij, nws yuav yog qhov tseeb dua hais tias qhov no tsis yog LED saib, tab sis yog saib nrog LED rov qab.
