Masiku ano, ma LED amagwiritsidwa ntchito kwambiri, koma diode yoyamba yotulutsa kuwala idapangidwa zaka 50 zapitazo ndi wogwira ntchito ku General Electric. Kuthekera kwa ma LED kunawonekera nthawi yomweyo, popeza anali ang'onoang'ono, olimba, komanso owala. Ma LED amadyanso mphamvu zochepa kuposa mababu a incandescent. Kwa zaka zambiri, teknoloji ya LED yapita patsogolo kwambiri. Mu zaka khumi zapitazi, lalikulu mkulu kusamvanaMawonekedwe a LEDakhala akugwiritsidwa ntchito m'mabwalo amasewera, mawayilesi a kanema wawayilesi, malo opezeka anthu onse, komanso ngati ma nyali owunikira ku Las Vegas ndi Times Square.
Zosintha zazikulu zitatu zakhudza mawonetsedwe amakono a LED: kukonza bwino, kuwala kowonjezereka, ndi kusinthasintha kotengera kugwiritsa ntchito. Tiyeni tifufuze mwatsatanetsatane.
Kusamvana Kokwezeka
Makampani owonetsera ma LED amagwiritsa ntchito kukwera kwa pixel ngati muyeso wokhazikika kuti awonetse kusintha kwa zowonetsera za digito. Pixel pitch ndi mtunda kuchokera pa pixel imodzi (LED cluster) kupita ku pixel ina pambali pake, pamwamba, kapena pansi pake. Ma pixel ang'onoang'ono amapanikizana, zomwe zimapangitsa kuti pakhale kusintha kwakukulu. Zowonetsera zakale kwambiri za LED zimagwiritsa ntchito mababu otsika kwambiri omwe amatha kungolemba zolemba. Komabe, kubwera kwa umisiri watsopano wa LED pamwamba pa pamwamba, ndizotheka kupanga osati zolemba zokha komanso zithunzi, makanema ojambula pamanja, mavidiyo, ndi zina zambiri. Masiku ano, mawonedwe a 4K okhala ndi ma pixel opingasa a 4,096 akukhala muyezo. Zosankha zapamwamba, monga 8K, ndizotheka, ngakhale sizodziwika.
Kuwonjezeka Kuwala
Magulu a LED omwe amapanga zowonetsera za LED apita patsogolo kwambiri. Masiku ano, ma LED amatha kutulutsa kuwala kowala bwino mumitundu yambirimbiri. Ma pixel kapena ma diode awa, akaphatikizidwa, amatha kupanga zowoneka bwino zowoneka kuchokera m'mbali zambiri. Ma LED tsopano amapereka milingo yowala kwambiri kuposa mtundu uliwonse wowonetsera. Kuwala kowala kumeneku kumapangitsa kuti zowonetsera zipikisane ndi kuwala kwadzuwa—ubwino waukulu paziwonetsero zakunja ndi zakutsogolo.
Kusiyanasiyana kwa Kugwiritsa Ntchito LED
Kwa zaka zambiri, mainjiniya akhala akugwira ntchito kuti azitha kuyika bwino zida zamagetsi panja. Zowonetsera za LED zimayenera kupirira zovuta za chilengedwe, kuphatikizapo kusinthasintha kwa kutentha kwa nyengo zambiri, kusinthasintha kwa chinyezi, ndi mpweya wamchere m'madera a m'mphepete mwa nyanja. Zowonetsera zamakono za LED ndizodalirika kwambiri m'nyumba ndi kunja, zomwe zimapereka mwayi wambiri wotsatsa ndi kufalitsa zambiri.
The sanali glare katundu waZojambula za LEDapangireni kusankha kokondedwa pazosintha zosiyanasiyana, kuphatikiza kuwulutsa, kugulitsa, ndi zochitika zamasewera.
Tsogolo
Mawonekedwe a Digital LEDzasintha kwambiri kwa zaka zambiri. Zowonetsera zakhala zazikulu, zoonda, ndipo zimabwera m'mawonekedwe ndi makulidwe osiyanasiyana. Zowonetsera zamtsogolo za LED zidzaphatikiza luntha lochita kupanga, kukulitsa kulumikizana, komanso kupereka njira zodzithandizira. Kuphatikiza apo, ma pixel apitililabe kuchepa, ndikupangitsa kuti pakhale zowonera zazikulu kwambiri zomwe zitha kuwonedwa pafupi popanda kudzipereka.
Hot Electronics amagulitsa zowonetsera zosiyanasiyana za LED. Yakhazikitsidwa mu 2003, Hot Electronics ndi mpainiya wopambana mphoto pazikwangwani za digito ndipo posachedwa wakhala m'modzi mwa omwe akuchulukirachulukira kwambiri padziko lonse lapansi ogulitsa ma LED, ogulitsa renti, ndi ophatikiza. Hot Electronics imathandizira mgwirizano kuti apange mayankho anzeru ndipo imakhalabe yoyang'ana makasitomala kuti ipereke chidziwitso chabwino kwambiri cha LED.
