Ko OLED inorevei uye inoshandiswa kupi?
OLED, iyo fomu yepamusoro ye LED, inomira yehuni-light emitting diode . Kusiyana neD LED, iyo inoshandisa mhanya kuti ipe chiedza kune mapikisi, OELD inotsigira pane zvinhu zvakagadzirwa nemidheni ye-hydrocarbon kuti ibudise chiedza apo inosangana nemagetsi.
Kune zvipo zvakasiyana-siyana kune nzira iyi, kunyanya kukwanisa kwepikisi imwe neimwe kujekesa ivo pachavo, zvichiita kuti zvive zvakasiyana-siyana zvakasiyana, zvinoreva kuti vatema vanogona kuva vakatsvuka zvakakwana uye vatsvene vanyatsojeka.
Ichi ndicho chikonzero chinoita kuti zvishandiso zvakawanda zviwedzere zvikwereti zveOLED, kusanganisira mafoni, mafaira akavharika semashandara, maTV, mahwendefa, madhidhiyo uye mapurisa anotarisa , uye digital kamera. Pakati pezvigadziro uye kune mamwe marudzi maviri ezviratidzo zveOLED zvinodzorwa nenzira dzakasiyana, dzinonzi kushanda-matrix (AMOLED) uye passive-matrix (PMOLED).
OLED Inoshanda Sei
Chirongwa cheOLED chinosanganisira zvimwe zvikamu. Mukati mehutakiti, inonzi substrate , inonzi cathode iyo inopa electrons, anode iyo "inokwevera" ma electrons, uye chikamu chepakati (organic organic) chinoparadzanisa.
Pakati pepakati pepakati pane zvikamu zviviri zvakare, rimwe rayo rinotarisirwa kubudisa chiedza uye chimwe chekubata chiedza.
Mucherechedzo wechiedza chinowanikwa paOLED kuratidzwa kunosangana nemavara matsvuku, matema, uye mabhuruu akabatanidzwa kune substrate. Kana ruvara rwuri dema, pixel inogona kubviswa kuti ione kuti hapana chiedza chinogadzirwa chekisi iyoyo.
Iyi nzira yekuumba dema yakasiyana zvikuru neye inoshandiswa ne LED. Apo imwe-inofanira kuva yepikisi yakasviba yakasvibiswa kune yakasviba pane chinyorwa che LED, pikisivha yepikisi yakavharwa asi kubvira kwacho kuchiri kubudisa chiedza, zvinoreva kuti hazviiti zvachose kuenda munzira yose yerima.
OLED Pros uye Cons
Kana ichienzaniswa ne LED uye mamwe maitiro ekuratidzira, OLED inopa zvikomborero izvi:
- Simba rinobudirira kubvira mushure mokudzokera shure hakusi kupiwa simba. Uyewo, kana dema iri kushandiswa, iyo mapikisi esirivha haadi simba pane zvose, nekuwedzera kuchengetedza simba.
- Dhora rezororo rinokurumidza zvikuru sezvo zvivharo zve pixel zvisisashandiswi.
- Nezvinhu zviduku zvishoma, kuratidzwa, uye saizvozvo chipfeve chakakwana, chinogona kuramba chakaonda uye chisingaregi.
- Muchena mutsvuku ndeyemusiya sezvo iyo mapikisi inogona kupfigirwa zvachose uye hakuna chiedza chiri pedyo kubva kune icho chinopa chiedza chinopera munzvimbo iyoyo. Izvi zvinobvumira kuenzanisa kwakanyanya chaizvo (kureva vatsvene vatsvuku pamusoro pevanhu vemausi madema).
- Inotsigira nzvimbo yakareba yakatarisa kunze kwekurasikirwa kwemavara akawanda se LED.
- Kusavapo kwezvimwe zvidimbu zvakanyanyisa zvinobvumira zviratidzo zvakakomberedzwa uye zvinokwanisika.
Zvisinei, panewo kusagadzikana kwekuratidzwa kweOLED:
- Sezvo chikamu chekuratidzira chiri choga, maOLED anoratidza kuora kwemavara kwenguva, iyo inokanganisa huwandu hwekwenyoro kupenya uye ruvara rwemavara. Izvi zvinowedzera kuwedzerwa nekufamba kubva pane zvinhu zvinodiwa pakuita blues kuora pamusana pfupi kupfuura reds uye magreens.
- Zviratidzo zveOLED zvinodhura kuita, zvichienzaniswa nekombiki yekare.
- Zvose zviviri OLED uye LED zvinoratidza ruzivo rwekwenyasi kupisa-mune kana mapikisikisi akasiyana-siyana anoshandiswa kwenguva yakareba kwenguva yakareba, asi mhedzisiro inowedzera kune OLED. Zvisinei, izvi zvinokonzerwa nehuwandu hwepiksekisi pamasendimita .
Mamwe Mashoko pamusoro peOLED
Hasi zvese zvikwangwani zveOLED zvakafanana; zvimwe zvishandise zvinoshandisa imwe rudzi rwe OLED panhizha nokuti vane kushandiswa kwakasiyana.
Semuenzaniso, smartphone inoda kubhadharwa kwepamusoro yezvifananidzo zveHDD uye dzimwe nguva-kuchinja zvigadzirwa, zvingashandisa zviratidzo zve AMOLED. Uyewo, nokuti zviratidzo izvi zvinoshandisa firimu-firimu transistor kushandura mapiksesi pa / kuvhara kuti varatidze ruvara, vanogona kunge vakajeka uye vane mafungiro, anonzi anogadziriswa OLEDs (kana FOLED).
Kune rumwe rutivi, chivigirati chinowanzoratidza ruzivo rumwechete pachikwangwani kwenguva yakareba kupfuura foni, uye iyo inozorodza zvishoma, inogona kushandisa teknolojia inopa simba kune dzimwe nzvimbo dzefirimu kusvikira yavandudzwa, sa PMOLED, kupi mutsara mumwe woga wekuratidzwa unotungamirirwa pane nzvimbo ye pixel imwe neimwe.
Zvimwe zvigadziri zvinoshandisa maonesheni eOLED zvinobva kune vanogadzirisa izvo zvinogadzirwa mafoni uye mashizha, saSamsung, Google, Apple, uye Essential Products; kamera makamera akadai saSon, Panasonic, Nikon, uye Fujifilm; mahwendefa kubva kuLenovo, HP, Samsung, uye Dell; laptops seAlienware, HP, uye Apple; vatariri kubva kuOxygen, Sony, uye Dell; uye terevhizheni kubva kuvakiki vakaita saToshiba, Panasonic, Bank & Olufsen, Sony, uye Loewe. Kunyange mamwe mota yemotokari uye mwenje anoshandisa teknolojia yeOLED.
Icho chiratidzo chinoumbwa hachirevi kuti chinotsanangura chigadziriso chacho . Mune mamwe mazwi, haugoni kuziva kuti chigadziro chii chekona (4K, HD, etc.) nokuti iwe unoziva kuti iOLED (kana Super AMOLED , LCD , LED, CRT , nezvimwewo).
QLED iyo izwi rakafanana iro shandisi inoshandisa kurondedzera panhizha apo ma LED anoputika nehupamhi hwemazamu dots kuti ave nechikwiriso chivhenekera mumarudzi akasiyana-siyana. Inomirira quantum-dot chiedza-emitting diode .
