Noocyada Bandhiga Mobilka: Waa maxay macnaha OLED, AMOLED, retina iyo in ka badan?

U telefoonada gacanta Waxaan inta badan la kulannaa calaamado kala duwan oo loogu talagalay bandhigyadooda. Si kastaba ha ahaatee, tignoolajiyada LCD ee hore loo isticmaali jiray ayaa lagu beddelay OLED, marka, tusaale ahaan, Samsung waxay ku dartay calaamado kala duwan. Si aad u hesho ugu yaraan wax yar oo cad, waxaad arki kartaa dulmar guud oo ku saabsan tignoolajiyada loo isticmaali karo bandhigyo kala duwan. Isla mar ahaantaana, Retina waa calaamad suuqgeyn oo kaliya.

LCD

Shaashadda crystal dareere ah waa qalab muuqaal khafiif ah oo fidsan oo ka kooban tiro xaddidan oo midab ah ama pixels monochrome ah oo lagu hor safan yahay isha iftiinka ama muraayada. Pixel kastaa waxa uu ka kooban yahay unugyo crystal dareere ah oo la dhex dhigo labada elektrodes ee hufan iyo inta u dhaxaysa laba filtarrada polarizing, oo leh faashashka polarization-ku siman yihiin midba midka kale. Haddii aanay jirin muraayadaha u dhexeeya filtarrada, iftiinka dhex mara shaandhada waxaa xannibi doona shaandhada kale.

OLED

Organic Light-Emitting Diode waa ereyga Ingiriisiga ee nooc ka mid ah LED-ka (taas oo ah, diodes electroluminescent), halkaas oo walxaha organic loo isticmaalo sida walaxda korantada. Tiknoolajiyadan ayaa aad iyo aad loogu isticmaalaa taleefannada gacanta, tan iyo markii Apple ay ugu dambeysay adeegsigeeda iPhone 11, markaasoo dhammaan faylalka 12 nooc ay mar hore u beddeleen OLED. ilaa 1987kii.

Sida ay yiraahdaan Czech Wikipedia, Markaa mabda'a tignoolajiyada ayaa ah in ay jiraan dhowr lakab oo walxaha dabiiciga ah ee u dhexeeya anode hufan iyo birta cathode. Waqtigan xaadirka ah marka korantada lagu dabaqo mid ka mid ah beeraha, kharashyada togan iyo kuwa taban ayaa la soo saaraa, kuwaas oo isku daraya lakabka soo baxaya oo sidaas darteed soo saara shucaac iftiin ah.

PMOLED

Kuwani waa bandhigyo leh matrix dadban, kuwaas oo ka fudud oo la heli karo isticmaalkooda gaar ahaan halka, tusaale ahaan, qoraalka kaliya loo baahan yahay in lagu soo bandhigo. Si la mid ah bandhigyada LCD garaafyada fudud, pixels-yada gaarka ah waxaa loo xakameeyaa si aan fiicneyn, iyadoo loo eegayo jaantuska xargaha ee fiilooyinka isdhaafsan. Isticmaalka sarreeya iyo muujinta liidata awgeed, PMOLEDs waxay si gaar ah ugu habboon yihiin bandhigyada leh geeso yaryar.

AMOLED

Bandhigyada matrixka firfircoon waxay ku habboon yihiin codsiyada garaafyada-dhaqdhaqaaqa leh ee leh xallin sare, tusaale ahaan soo bandhigida muuqaal iyo muuqaallo, waxaana si weyn loogu isticmaalaa taleefannada gacanta. Beddelka pixel kasta waxaa fuliyaa transistor u gaar ah, kaas oo ka hortagaya, tusaale ahaan, ilbidhiqsiyada dhibcaha ee loo maleynayo inay iftiiminayaan inta lagu jiro dhowr wareeg oo isku xigta. Faa'iidooyinka cad waa soo noqnoqoshada soo noqnoqda sare, samaynta sawir fiiqan iyo, ugu dambeyntii, isticmaalka hoose. Taa bedelkeeda, khasaarooyinka waxaa ka mid ah qaab-dhismeed aad u adag oo muuqaal ah iyo sidaas awgeed qiimaha sarreeya.

Laabi

Halkan, qaabka OLED waxaa lagu dhejiyaa walxo dabacsan halkii muraayadda. Tani waxay u oggolaanaysaa bandhigga inuu si fiican ula qabsado goobta, sida dashboard-ka ama xitaa muraayadaha koofiyada ama muraayadaha. Walaxda la isticmaalay waxa ay sidoo kale dammaanad qaadaysaa iska caabin farsamo oo weyn, sida shoog iyo dhicis.

TOOSA

Farsamadan ayaa suurtogal ka dhigaysa in la abuuro muuqaal leh illaa 80% gudbinta iftiinka. Tan waxaa lagu gaaraa cathode hufan, anode iyo substrate, kuwaas oo noqon kara galaas ama caag. Habkani waxa uu ogolaanayaa in macluumaadka lagu soo bandhigo goobta adeegsadaha ee muuqaalada dusha kale ee hufan, taas oo ka dhigaysa mid aad ugu dhow FLED.

Magacaabista retina

Tani dhab ahaantii waa magac ganacsi oo loogu talagalay bandhigyada ku salaysan IPS panel ama tignoolajiyada OLED oo leh cufnaanta pixel sare. Dabcan waxaa taageera Apple, kaas oo u diiwaan gashan sidii calaamad ganacsi oo aan sidaas darteed loo isticmaali karin wax soo saar kale oo la xidhiidha bandhigyada.

Tani waxay la mid tahay summada Super AMOLED ee ay Samsung ku isticmaasho aaladeeda. Waxay isku daydaa inay ku darto subpixels dheeraad ah iyada oo leh qaab khafiif ah, muuqaal cad iyo isticmaalka tamarta hoose.
