Kodi OLED imatanthauza chiyani ndipo amagwiritsidwa ntchito kuti?
OLED, mawonekedwe apamwamba a LED, amaimira diode ya emitting diode . Mosiyana ndi LED, yomwe imagwiritsa ntchito khungu lakumbuyo kuti likhale lowala kwa pixels, OELD ikudalira pa zinthu zakuthupi zopangidwa ndi maunyolo a hydrocarbon kuti ziwone kuwala pamene zimagwirizana ndi magetsi.
Pali ubwino wambiri pa njirayi, makamaka kuthekera kwa pixel iliyonse kuti ikhale yosavuta payekha, kutulutsa chiyero chosiyana kwambiri, kutanthauza kuti wakuda akhoza kukhala wakuda kwathunthu ndipo azungu akuwala kwambiri.
Ichi ndicho chifukwa chachikulu chomwe zipangizo zambiri zimagwiritsira ntchito zojambula za OLED, kuphatikiza mafoni a m'manja, zipangizo zodzikongoletsera monga mawotchi, ma TV, mapiritsi, mawotchi ndi mawotchi apakompyuta, ndi makamera a digito. Zina mwa zipangizozi ndi zina ndi mitundu iwiri ya ma OLED mawonetsedwe omwe amayendetsedwa m'njira zosiyanasiyana, otchedwa yogwira-matrix (AMOLED) ndi osakaniza matrix (PMOLED).
Momwe OLED Amagwirira Ntchito
Pulogalamu ya OLED ili ndi zigawo zingapo. M'kati mwake, amatchedwa substrate , ndi cathode yomwe imapereka magetsi, anode omwe "amakoka" magetsi, ndi gawo lopakati (organic layer) lomwe limalekanitsa iwo.
Mkatikatikati mwa chigawo chapakati muli zigawo ziwiri zina, zomwe zimayambitsa kupanga kuwala ndi zina kuti zipeze kuwala.
Mtundu wa kuwala umene ukuwoneka pa mawonedwe OLED umakhudzidwa ndi zigawo zofiira, zobiriwira, ndi za buluu zomwe zimapezeka pa gawo lapansi. Pamene mtundu uyenera kukhala wakuda, pixel ingathe kutsekedwa kuti zitsimikizire kuti palibe kuwala komwe kwapangidwa kwa pixel imeneyo.
Njira iyi yopanga wakuda ndi yosiyana kwambiri ndi yomwe imagwiritsidwa ntchito ndi LED. Pamene pixel yakuda imakhala yakuda pazenera la LED, shutter ya pixel imatsekedwa koma kuwala kwawunikira kumatulutsa kuwala, kutanthauza kuti sikumayendera mdima wonse.
OLED Pros ndi Cons
Poyerekeza ndi LED ndi matekinoloje ena owonetsera, OLED imapindula izi:
- Mphamvu zamagetsi kuyambira ku backlight sizinayambike. Komanso, pamene wakuda akugwiritsidwa ntchito, ma pixel enieni samasowa mphamvu, kupulumutsa mphamvu.
- Mawindo otsitsimula amathamanga mofulumira kwambiri popeza zitsulo za pixel zisagwiritsidwe ntchito.
- Popanda zigawo zikuluzikulu, mawonetsedwe, motero chipangizo chonse, chingakhale chochepa komanso chopepuka.
- Mtundu wakuda uli wakuda chifukwa ma pixel omwe amatha kutsekedwa kwathunthu ndipo palibe kuwala komwe kumakhala kumbuyo komwe kumapangitsa kuwala kumaloko. Izi zimapangitsa chiŵerengero chosiyana kwambiri (ie, azungu zoyera kwambiri pamdima wakuda kwambiri).
- Amathandizira mbali yowonongeka yopanda maonekedwe ambiri ngati LED.
- Kupezeka kwa zigawo zina zochepa kumapangitsa mawonedwe obisika ndi owoneka bwino.
Komabe, palinso zovuta kuwonetsera OLED:
- Popeza mbali ina yawonetseratu ndi yowonongeka, ma OLED amasonyeza kuwonongeka kwa mtundu pakapita nthawi, zomwe zimakhudza kuwonetsera kwa pulojekiti komanso kuwonetsera mtundu. Izi zimaipiraipira ndi nthawi kuchokera ku zinthu zomwe zimafunika kupanga kupweteka kosavuta mofulumira kusiyana ndi reds ndi masamba.
- Mawindo a OLED ndi okwera mtengo, osachepera poyerekeza ndi makanema akale.
- Onse OLED ndi Dzuwa amawonetsera zochitika zowonetsera zojambulazo ngati ma pixel apadera amagwiritsidwa ntchito motalika kwambiri kwa nthawi yaitali, koma zotsatira zake ndi zazikulu pa OLED. Komabe, zotsatirazi ndi gawo lomwe limatsimikiziridwa ndi chiwerengero cha pixels pa inchi .
Zambiri Zokhudza OLED
Osati zojambula zonse za OLED zili zofanana; Zipangizo zina zimagwiritsa ntchito mtundu wina wa gulu la OLED chifukwa ali ndi ntchito yapadera.
Mwachitsanzo, foni yamakono yomwe imakhala ndi mpweya wabwino wa zithunzi za HD ndi zinthu zina zosintha nthawi zonse, zingagwiritse ntchito mawonedwe a AMOLED. Komanso, chifukwa mawonetseredwewa amagwiritsira ntchito filimu yopyapyala kuti asinthe ma pixels kuti awone mtundu, akhoza kuwonekera momveka bwino komanso otengeka, otchedwa OLEDs (kapena FOLED) omwe amasinthasintha.
Kumbali ina, kakompyuta yomwe kawirikawiri imawonetsera chidziwitso chomwecho pawindo kwa nthawi yaitali kuposa foni, ndipo izo zimatsitsimula mobwerezabwereza, zingagwiritse ntchito teknoloji yomwe imapereka mphamvu ku malo enieni a kanema mpaka itatsitsimutsidwa, monga PMOLED, kumene Mzere uliwonse wawonetsedwe ukulamulidwa mmalo mwa pixel iliyonse.
Zida zina zomwe zimagwiritsa ntchito maofesi OLED zimachokera kwa ojambula omwe amagula mafoni ndi mafoni, monga Samsung, Google, Apple, ndi Essential Products; makamera adijito monga Sony, Panasonic, Nikon, ndi Fujifilm; mapiritsi a Lenovo, HP, Samsung, ndi Dell; laptops ngati Alienware, HP, ndi Apple; oyang'anira kuchokera ku Oxygen, Sony, ndi Dell; ndi ma TV kuchokera kwa ojambula monga Toshiba, Panasonic, Bank & Olufsen, Sony, ndi Loewe. Ngakhalenso ma radiyo ndi magetsi amagwiritsa ntchito makina opangira OLED.
Ndiwonetsedwe kotani komwe kumapangidwira sikukutanthauzira chisankho chake. Mwa kuyankhula kwina, simungadziwe kuti yankho lanu ndi lotani (4K, HD, etc.) chifukwa chakuti mukudziwa kuti ndi OLED (kapena Super AMOLED , LCD , LED, CRT , etc.).
QLED ndi mawu ofanana omwe Samsung amagwiritsa ntchito pofotokoza gulu limene ma LED akuphatikizana ndi zowonjezereka za madontho kuti zowonetsera ziwonekere mu mitundu yosiyanasiyana. Chimaimira choyimira-dothi la emitting diode .
