Mafambiro eOLED Displays

OLED (Organic Light-Emitting Diode) inoreva ma organic light-emitting diodes, ayo anomiririra chigadzirwa chitsva munyaya dzemafoni. Kusiyana netekinoroji yeLCD yechinyakare, tekinoroji yeOLED display haidi backlight. Pane kudaro, inoshandisa macoatings e organic material akatetepa uye magirazi substrates (kana flexible organic substrates). Kana magetsi ashandiswa, zvinhu izvi zve organic zvinoburitsa chiedza. Uyezve, ma OLED screens anogona kuitwa akareruka uye akatetepa, anopa ma angle akafara ekuona, uye anoderedza zvakanyanya kushandiswa kwesimba. OLED inonziwo tekinoroji yechitatu yekuratidza. Ma OLED screens haasi matete chete, akareruka, uye anoshanda nesimba zvakanyanya asiwo ane kupenya kwakanyanya, kushanda zvakanaka kwe luminescence, uye kugona kuratidza dema chairo. Pamusoro pezvo, anogona kunge akakombama, sezvinoonekwa mumaTV emazuva ano ane curved-screen nemafoni. Nhasi, vagadziri vakuru vepasi rose vari kumhanya-mhanya kuwedzera mari muR&D mu OLED display technology, zvichiita kuti ishandiswe zvakanyanya mumaTV, makomputa (monitors), mafoni, mapiritsi, nedzimwe nzvimbo. Muna Chikunguru 2022, Apple yakazivisa hurongwa hwekuisa ma OLED screens ku iPad lineup yayo mumakore anotevera. Ma iPad egore ra2024 ari kuuya achange aine mapaneru eOLED akagadzirwa, maitiro anoita kuti mapaneru aya ave matete uye akareruka.

Nheyo yekushanda kweOLED displays yakasiyana zvachose neyeLCDs. MaOLED anotungamirwa nesimba remagetsi, anowana chiedza kuburikidza nekupinza nekubatanidza macharge carriers muzvinhu zve organic semiconductor uye luminescent. Muchidimbu, OLED screen inoumbwa nemamiriyoni e "light bulbs" diki.

Mudziyo weOLED unonyanya kuve ne substrate, anode, hole injection layer (HIL), hole transport layer (HTL), electron blocking layer (EBL), emissive layer (EML), hole blocking layer (HBL), electron transport layer (ETL), electron injection layer (EIL), uye cathode. Maitiro ekugadzira tekinoroji yeOLED display anoda hunyanzvi hwakanyanya hwehunyanzvi, hwakakamurwa zvakanyanya mu front-end uye back-end processes. Maitiro efront-end anonyanya kusanganisira photolithography uye evaporation techniques, nepo back-end process ichinyanya kutarisa pa encapsulation uye cutting technologies. Kunyangwe tekinoroji yeOLED yepamusoro ichinyanya kunzwisiswa neSamsung neLG, vagadziri vazhinji vekuChina vari kuwedzerawo kutsvagisa kwavo maOLED screens, vachiwedzera mari muOLED displays. Zvigadzirwa zveOLED display zvatobatanidzwa muzvipo zvavo. Pasinei nemusiyano wakakura zvichienzaniswa nemakambani makuru epasi rose, zvigadzirwa izvi zvasvika padanho rinoshanda.
