OLED miyuu u roon yahay Indhahaaga?

Maaddaama wakhtiga shaashadu uu sii kordhayo adduunka oo dhan, welwelka ku saabsan saamaynta tignoolajiyada soo bandhigida ee caafimaadka indhaha ayaa kor u kacay. Doodaha dhexdooda, hal su'aal ayaa ka soo baxaysa: Tignoolajiyada OLED (Organic Light-Emitting Diode) miyuu runtii u fiican yahay indhahaaga marka loo eego shaashadaha LCD-ga caadiga ah? Allow's u quuso sayniska, faa'iidooyinka, iyo godadka bandhigyada OLED.

Shaashadaha OLED waxay caan ku yihiin midabadooda firfircoon, madow qoto dheer, iyo waxtarka tamarta. Si ka duwan LCD-yada, kuwaas oo ku tiirsan iftiinka dambe, pixel kasta oo ku jira guddi OLED ah ayaa bixiya iftiin u gaar ah. Naqshaddan gaarka ah waxay bixisaa laba faa'iidooyin oo suurtagal ah raaxada indhaha:

Hooska Iftiinka Buluugga ah

Daraasaduhu waxay soo jeedinayaan in soo-gaadhista dheer ee ** iftiinka buluuga ah ***-gaar ahaan 400-450 nm dhererka mawjada-waxay carqaladayn kartaa wareegyada hurdada waxayna gacan ka geysan kartaa cadaadiska indhaha dhijitaalka ah. Shaashadaha OLED waxay sii daayaan iftiin buluug ah oo ka yar LCD-yada caadiga ah, gaar ahaan marka ay muujinayaan waxyaabo madow. Marka loo eego warbixin 2021 ee *Harvard Health Publishing*, OLED'Awoodda lagu dhimi karo pixels-ka gaarka ah (halkii la isticmaali lahaa nalka dambe ee lebbiska ah) waxay yaraynaysaa guud ahaan soosaarka iftiinka buluugga ilaa 30% qaab mugdi ah.

Waxqabadka Flicker-free

Shaashado badan oo LCD ah ayaa isticmaala PWM (Modulation Width Modulation Pulse) si ay u hagaajiyaan iftiinka, kaas oo si degdeg ah u wareega iftiinka dambe ee shidan iyo daminta. Libaaxan, oo inta badan aan la fahmi karin, ayaa lala xiriiriyay madax-xanuun iyo daalka indhaha ee shakhsiyaadka xasaasiga ah. Shaashadaha OLED, si kastaba ha ahaatee, waxay xakameeyaan dhalaalka iyagoo si toos ah u hagaajinaya iftiinka pixel, iyaga oo meesha ka saaraya qulqulka inta badan.

Iyadoo OLEDs ay ballan qaadayaan, saameyntooda caafimaadka indhaha waxay kuxirantahay qaababka isticmaalka iyo hirgelinta tignoolajiyada:

PWM ee OLED-yada qaarkood Si la yaab leh, bandhigyada OLED qaarkood (tusaale, taleefannada casriga ah ee miisaaniyada) ayaa wali u isticmaala PWM goobaha iftiinka hooseeya si loo badbaadiyo awoodda. Tani waxay dib u soo celin kartaa arrimo liidata.

Iftiinka Xad dhaafka ah:Shaashado OLED ah oo lagu dejiyay iftiinka ugu sarreeya ee jawiga mugdiga ah ayaa laga yaabaa inay keenaan dhaldhalaal, ka hortagga faa'iidooyinkooda iftiinka buluugga ah.

Khatarta Gubashada:Walxaha joogtada ah (tusaale, baararka navigation) ee OLEDs waxay hoos u dhigi karaan pixels waqti ka dib, taasoo ku dhiirigelisa isticmaalayaasha inay kordhiyaan iftiinka-xanuunka isha oo laga yaabo inuu ka sii daro.

Aragtida Khubarada

Dr. Lisa Carter, oo ah dhakhtarka indhaha oo ka tirsan Machadka Caafimaadka Vision, ayaa sharaxday:

"OLED-yadu waa tallaabo hore loogu qaaday raaxada indhaha, gaar ahaan iftiinka buluuga ah ee la dhimay iyo qalliinka bilaa flicker ah. Si kastaba ha noqotee, isticmaalayaashu waa inay wali raacaan qaanuunka 20-20-20: 20kii daqiiqaba, fiiri wax 20 cagood u jira 20 ilbiriqsi. Ma jiro tignoolajiyada shaashadda bedeli karta caadooyinka caafimaadka qaba.”

Dhanka kale, falanqeeyayaasha tikniyoolajiyaddu waxay muujinayaan horumarka hababka daryeelka indhaha ee OLED:Samsung's "Gaashaanka Raaxada Isha”si firfircoon u habeeya iftiinka buluuga ah oo ku salaysan wakhtiga maalinta.LG's "Aragtida Raaxada”wuxuu isku daraa iftiinka buluuga ah ee hooseeya iyo dahaarka ka-hortagga muraayadaha.

Shaashado OLED ah, oo leh isbarbardhiggooda sare iyo iftiinka buluugga ah oo yaraaday, waxay bixiyaan faa'iido cad oo raaxada indhaha marka loo eego LCD-yada caadiga ah-waase haddii si masuuliyadi ku jirto loo isticmaalo. Si kastaba ha ahaatee, arrimo ay ka mid yihiin goobaha dhalaalka, hawlgalka bilaa flicker, iyo caadooyinka ergonomic ayaa weli ah mid muhiim ah.
