Kupangidwa kwa wailesi yakanema kwachititsa kuti anthu aziona zinthu zosiyanasiyana popanda kuchoka m’nyumba zawo. Ndi kupita patsogolo kopitilira muyeso kwaukadaulo, anthu ali ndi zofunikira zapamwamba komanso zapamwamba za zowonera pa TV, monga mawonekedwe apamwamba, mawonekedwe abwino, moyo wautali wautumiki, ndi zina zambiri. Mukamagula TV, mudzasokonezeka mukamawona mawu ngati "LED ”, “MiniLED”, “microled” ndi mawu ena amene amayambitsa zenera pa intaneti kapena m'masitolo enieni. Nkhaniyi idzakutengerani kuti mumvetse zamakono zamakono zowonetsera "MiniLED" ndi "microled", ndipo pali kusiyana kotani pakati pa ziwirizi.
Mini LED ndi "sub-millimeter light-emitting diode", kutanthauza ma LED okhala ndi makulidwe a chip pakati pa 50 ndi 200μm. Mini LED idapangidwa kuti ithetse vuto la kusakwanira kokwanira kwa kayendetsedwe ka kuwala kwachikhalidwe cha LED. Makhiristo otulutsa kuwala kwa LED ndi ang'onoang'ono, ndipo makhiristo ochulukirapo amatha kulowetsedwa mu gulu la backlight pagawo lililonse, kotero mikanda yowunikira kumbuyo imatha kuphatikizidwa pazenera lomwelo. Poyerekeza ndi ma LED achikhalidwe, ma Mini LED amakhala ndi voliyumu yaying'ono, amakhala ndi mtunda waufupi wosanganikirana, kuwala kwambiri ndi kusiyanitsa, kugwiritsa ntchito mphamvu zochepa, komanso moyo wautali.
Microled ndi "micro light-emitting diode" ndipo ndi ukadaulo wocheperako komanso wowoneka bwino wa LED. Itha kupanga gawo la LED kukhala laling'ono kuposa 100μm ndipo lili ndi makhiristo ang'onoang'ono kuposa Mini LED. Ndi filimu yopyapyala, yopangidwa ndi miniaturized komanso yopangidwa ndi LED backlight source, yomwe imatha kukwaniritsa munthu aliyense payekhapayekha pazithunzi zilizonse ndikuyiyendetsa kuti ipereke kuwala (self-luminescence). Wosanjikiza wotulutsa kuwala amapangidwa ndi zinthu zopanda organic, kotero sikophweka kukhala ndi zovuta zowotcha pazenera. Nthawi yomweyo, kuwonekera pazenera ndikwabwino kuposa LED yachikhalidwe, yomwe imapulumutsa mphamvu. Microled ili ndi mawonekedwe owala kwambiri, kusiyanitsa kwakukulu, kutanthauzira kwakukulu, kudalirika kwamphamvu, nthawi yoyankha mwachangu, kupulumutsa mphamvu zambiri, komanso kugwiritsa ntchito mphamvu zochepa.
Mini LED ndi microLED zili ndi zofanana zambiri, koma poyerekeza ndi Mini LED, microLED ili ndi mtengo wapamwamba komanso zokolola zochepa. Akuti Samsung ya 110-inch MicroLED TV mu 2021 idzawononga ndalama zoposa $ 150,000. Kuphatikiza apo, ukadaulo wa Mini LED ndi wokhwima, pomwe microLED ikadali ndi zovuta zambiri zaukadaulo. Ntchito ndi mfundo ndizofanana, koma mitengo ndi yosiyana kwambiri. Kutsika mtengo pakati pa Mini LED ndi microLED ndizodziwikiratu. Mini LED ikuyenera kukhala mayendedwe apakatikati pakukula kwaukadaulo wapa TV.
MiniLED ndi microLED zonse ndizomwe zimachitika muukadaulo wowonetsera mtsogolo. MiniLED ndi mtundu wosinthika wa microLED komanso ndiyomwe imadziwika kwambiri paukadaulo wamakono wowonetsera.
