Ndi chitukuko chofulumira chaukadaulo wamakono wolumikizirana ndi mafoni ndi umisiri wapa intaneti wopanda zingwe, dziko lapansi lalowa mu "nthawi yachidziwitso" yatsopano, ndipo zomwe zili muzambiri zikuchulukirachulukira komanso zokongola. Monga gawo lofunika kwambiri pazamalonda, teknoloji yowonetsera nthawi zonse yakhala ikugwira ntchito yofunika kwambiri pa chitukuko cha zamakono.
Masiku ano matekinoloje owonetsera ndi osatha komanso osiyanasiyana. Zowonetsera zosiyanasiyana zatizungulira, zomwe zimatibweretsera zokometsera zambiri pa ntchito ndi moyo wathu, komanso zimabweretsa zowoneka bwino.
1. LED
LED, kapena Light Emitting Diode, ndi chipangizo cholimba cha semiconductor chomwe chimatha kusintha magetsi kukhala kuwala. Kuwala kwa LED kukakhala ndi voteji yakutsogolo, ma elekitironi amabayidwa kuchokera kudera la N kupita kudera la P ndikuphatikizana ndi mabowo kuti apange ma electron-hole awiriawiri. Ma electron ndi mabowowa amatulutsa mphamvu mu mawonekedwe a photons panthawi yogwirizanitsa. LED ili ndi mawonekedwe amphamvu kwambiri, kupulumutsa mphamvu, kuteteza chilengedwe, kuthamanga kwachangu, kuwala kwakukulu ndi mitundu yolemera, ndipo imagwiritsidwa ntchito kwambiri pakuwunikira, kuwonetsa ndi madera ena. Pali ntchito ziwiri zazikulu zaukadaulo wowonetsera LED. Imodzi ili ngati gwero la backlight la LCD kuti lilowe m'malo mwa CCFL (nyali yozizira ya cathode fluorescent), kotero kuti LCD ili ndi mawonekedwe amtundu wamtundu wamtundu wambiri, mawonekedwe owonda kwambiri, kupulumutsa mphamvu ndi kuteteza chilengedwe; yachiwiri ndi chiwonetsero cha LED, chomwe chimagwiritsa ntchito LED mwachindunji monga gawo lowonetsera, chikhoza kugawidwa mu mawonedwe a monochrome ndi maonekedwe a mtundu. Lili ndi zizindikiro za kuwala kwakukulu, kutanthauzira kwakukulu ndi mitundu yowala. Amagwiritsidwa ntchito kwambiri m'zikwangwani, masitepe, malo ochitira masewera ndi zochitika zina.
2. OLED
OLED ndi Organic Light Emitting Diode (Organic Light Emitting Diode), yomwe imadziwikanso kuti organic electric laser display ndi organic light-emitting semiconductor. Ndi organic semiconductor material ndi luminescent material yomwe imatulutsa kuwala kudzera mu jakisoni ndikuphatikizanso zonyamulira poyendetsa magetsi. Ndi mtundu wamakono. lembani zida zotulutsa organic.
OLED imatchedwa teknoloji yowonetsera m'badwo wachitatu. Chifukwa ndi yocheperako, imakhala ndi mphamvu zochepa, yowala kwambiri, yowala bwino, imatha kuwonetsa zakuda, komanso imatha kupindika, ukadaulo wa OLED wakhala chinthu chofunikira kwambiri pa ma TV, ma monitor, ndi mafoni amakono. , mapiritsi ndi madera ena amagwiritsidwa ntchito kwambiri.
3. QLED
QLED, Quantum Dot Light Emitting Diode (Quantum Dot Light Emitting Diode), ndiukadaulo wotulutsa kuwala wotengera madontho a kuchuluka. Chigawo cha madontho a quantum chimayikidwa pakati pa zoyendera ma elekitironi ndi zotengera za organic, ndipo gawo lamagetsi lakunja limayikidwa kusuntha ma elekitironi ndi mabowo. mu quantum dont layer, ndiyeno ma elekitironi ndi mabowo amalumikizananso kuti atulutse kuwala. Mapangidwe a QLED ndi ofanana ndi a OLED. Kusiyana kwakukulu ndikuti zida zotulutsa zowunikira za QLED ndizinthu zamadontho a inorganic quantum, pomwe OLED imagwiritsa ntchito zinthu zachilengedwe. QLED ili ndi mawonekedwe otulutsa kuwala kogwira ntchito, kuwala kowala kwambiri, liwiro loyankhira mwachangu, mawonekedwe osinthika, mawonekedwe amtundu wamtundu, ndi zina zambiri. Ndiwokhazikika komanso amakhala ndi moyo wautali kuposa OLED. Pali mitundu iwiri yayikulu yogwiritsira ntchito ukadaulo wa QLED. Imodzi ndi teknoloji ya quantum dot backlight yochokera ku photoluminescence katundu wa madontho a quantum, ndiko kuti, kuwonjezera madontho a quantum kumbuyo kwa LCD kuti apititse patsogolo kubereka ndi kuwala; ina ndi ukadaulo wa quantum dot backlight. Tekinoloje yowonetsera ma diode ya Quantum dot light-emitting diode yotengera ma electroluminescence a madontho a quantum, ndiye kuti, madontho a quantum amaikidwa pakati pa maelekitirodi kuti atulutse kuwala, kuwongolera kusiyanitsa ndi ma angles owonera. Pakalipano, zowonetsera za QLED zochokera ku quantum dot backlight mode zakhala zikugwiritsidwa ntchito kwambiri pamsika. Zomwe zimatchedwa "quantum dot TV" pamsika kwenikweni ndi ma TV a LCD omwe ali ndi mafilimu amtundu wa quantum, ndipo akadali ukadaulo wa LCD.
4. Mini LED
Mini LED ndi sub-millimeter light emitting diode (Mini Light Emitting Diode), chomwe ndi chipangizo cha LED chokhala ndi kukula kwa chip pakati pa 50-200μm. Ndi zotsatira za kukonzanso kwina kwa ma LED ang'onoang'ono.
Mapulogalamu a Mini LED amagawidwa makamaka kuti agwiritse ntchito tchipisi ta Mini LED monga njira zowunikira zowunikira za LCD ndi njira zodziwunikira zokha zomwe zimagwiritsa ntchito ma RGB amitundu itatu, ndiko kuti, mayankho a backlight ndi mayankho owonetsera mwachindunji. Kuwala kwa Mini LED ndi njira yofunikira pakukweza kwaukadaulo wa LCD, komwe kumatha kuwongolera kuwala kwa LCD ndi kusiyanitsa kwakuda ndi mawonekedwe amphamvu, potero kumathandizira kuwona bwino. Chiwonetsero chachindunji chaching'ono cha Mini LED chimatha kugawanika mosiyanasiyana kukula kulikonse, kukulitsa mawonekedwe ogwiritsira ntchito zowonetsera zazikulu zazikulu. Ithanso kusintha kwambiri mawonekedwe owonetsera monga kusiyanitsa, kuya kwa mtundu, ndi tsatanetsatane wamitundu.
5. Micro LED
Micro LED, Micro Light Emitting Diode, yomwe imadziwikanso kuti mLED kapena μLED, ndiukadaulo wowonetsera wa LED wotengera mulingo wa micron. Imachepetsa tchipisi ta LED mpaka pamlingo wa micron ndikuphatikiza mamiliyoni aiwo mugawo lowonetsera. Chip cha LED chimazindikira chiwonetsero chazithunzi powongolera kuyatsa ndi kutseka kwa chip chilichonse cha LED. Micro LED imatha kunenedwa kuti imaphatikiza zabwino zonse za LCD ndi OLED. Lili ndi ubwino waukulu monga kusamvana kwakukulu, kugwiritsa ntchito mphamvu zochepa, kuwala kwakukulu, kusiyana kwakukulu, kutulutsa mitundu yambiri, kuyankha mofulumira, makulidwe owonda, ndi moyo wautali. Komabe, pakali pano ikuyang'ana Njira yopangira zinthu ndizovuta ndipo mtengo wopangira ndi wokwera.
Pakanthawi kochepa, msika wa Micro LED umayang'ana kwambiri zowonetsera zazing'ono. Pakatikati mpaka nthawi yayitali, Micro LED ili ndi ntchito zambiri, zipangizo zovala zogwiritsira ntchito, zowonetsera zazikulu zamkati, zowonetsera mutu (HMD), zowonetsera mutu (HUD), zowunikira galimoto, mauthenga opanda waya opanda waya Li-Fi, ndi AR / VR, mapulojekiti ndi zina.
6. Micro OLED
Micro OLED, yomwe imadziwikanso kuti silicon-based OLED, ndi kachipangizo kakang'ono kosonyeza kutengera luso la OLED. Amagwiritsa ntchito njira imodzi ya silicon crystal ndipo ali ndi makhalidwe odziwunikira okha, kachulukidwe kakang'ono ka pixel, kachulukidwe kakang'ono, kugwiritsa ntchito mphamvu zochepa, kusiyana kwakukulu komanso kuthamanga kwachangu.
Ubwino wa Micro OLED makamaka umachokera ku kuphatikiza kwaukadaulo wa CMOS ndi ukadaulo wa OLED, komanso kuphatikizika kwakukulu kwa zida za semiconductor ndi organic semiconductor zida. Mosiyana ndi zowonetsera zachikhalidwe za OLED zomwe zimagwiritsa ntchito magawo agalasi, ma Micro OLED amagwiritsa ntchito magawo a silicon monocrystalline, ndipo dera loyendetsa dalaivala limaphatikizidwa mwachindunji pagawo, kuchepetsa makulidwe onse a chinsalu. Ndipo chifukwa imagwiritsa ntchito ukadaulo wa semiconductor, masitayilo ake a pixel amatha kukhala motengera ma microns angapo, potero akuwonjezera kuchuluka kwa pixel. Zitha kumveka bwino ngati kugwiritsa ntchito ukadaulo wopanga chip kupanga zowonera.
Micro OLED ndi OLED ndizofanana kwenikweni. Kusiyana kwakukulu pakati pawo ndi "Micro". OLED yaying'ono imatanthawuza ma pixel ang'onoang'ono ndipo ndi oyenera kugwiritsidwa ntchito pazida zing'onozing'ono, zogwira ntchito kwambiri, zowonetsera kwambiri monga zowonetsera mutu (HMD) ndi zowonera zamagetsi (EVF).
