LED zaub (LED vaj huam sib luag): LED yog lub ntsiab lus ntawm lub teeb emitting diode, lossis LED luv luv. Nws siv lub hauv paus ntsiab lus ntawm semiconductor PN junction electroluminescence los tsim cov xim liab, ntsuab, thiab xiav. Nws yog ib qho khoom siv semiconductor uas tsis tau tsim nyob rau xyoo 1960. Nyob rau xyoo 1970, nrog rau kev nce qib ntawm kev tshawb fawb ntawm cov khoom siv hluav taws xob semiconductor synthesis thev naus laus zis, ib qho siv lead ua tsim tshuab, thiab PN junction tsim tshuab, kev ua haujlwm ntawm lub teeb-emitting diodes nyob rau hauv cov nqe lus ntawm luminous xim thiab brightness tau txhim kho thiab sai sai nkag mus rau ntau lawm thiab siv tau. . Nyob rau xyoo 1980, LEDs tau zoo heev nyob rau hauv cov nqe lus ntawm luminous wavelength ntau yam thiab kev ua tau zoo, thiab pib tsim cov khoom vaj huam sib luag vaj huam sib luag, uas yog LED cov ntxaij vab tshaus. Thaum xyoo 1980s lig, ib hom tshiab ntawm cov ntaub ntawv qhia tawm uas tau tsim sai heev thoob ntiaj teb siv dot matrix modules lossis pixel units uas muaj lub teeb-emitting diodes los ua ib qho chaw loj loj. Nrog rau cov yam ntxwv ntawm kev ntseeg siab, kev pab lub neej ntev, muaj zog ib puag ncig adaptability, siab tus nqi-kev ua tau zoo piv, thiab tus nqi qis ntawm kev siv, nws tau loj hlob sai rau hauv cov khoom tseem ceeb ntawm cov vaj huam sib luag hauv ib xyoo caum thiab tau siv dav hauv cov khoom lag luam. teb cov ntaub ntawv tso saib [1].
LED cov ntxaij vab tshaus tau muab faib ua cov duab kos duab thiab cov ntxaij vab tshaus video, ob qho tib si yog tsim los ntawm LED matrix blocks. Graphics cov ntxaij vab tshaus tuaj yeem tso saib cov cim Suav, cov ntawv Askiv thiab cov duab ua ke nrog cov khoos phis tawj; vis dis aus cov ntxaij vab tshaus yog tswj los ntawm microcomputers, nrog cov duab, cov duab thiab cov duab nplua nuj, thiab tuaj yeem ua si ntau yam ntaub ntawv hauv lub sijhawm tiag tiag, synchronous thiab meej cov ntaub ntawv kis tau tus mob, thiab tseem tuaj yeem tso tawm ob-seem thiab peb-dimensional animations, yeeb yaj kiab, TV , VCD cov kev pab cuam thiab cov xwm txheej nyob. LED cov ntxaij vab tshaus tso saib cov duab nyob rau hauv cov xim ci thiab muaj zog peb-dimensional kev nkag siab, zoo li ntsiag to li roj paintings thiab dynamic li tsos. Lawv tau dav siv nyob rau hauv chaw nres tsheb, docks, tshav dav hlau, khw malls, tsev kho mob, tsev so, tsev txhab nyiaj, kev lag luam kev nyab xeeb, kev tsim kho kev lag luam, auction tsev, kev lag luam kev lag luam thiab lwm qhov chaw pej xeem.
