OLED kya hai aur kaise kam karta hai in Hindi


Kya aapko pata hai ki OLED kya hai? hal hi men aap sabhi ne es OLED Display ke baare men jarur sunaa hogaa kyunki iPhone X aur Samsung Galaxy Note 8 donon men esbaar Manufacturer ne OLED Display kaa estmaal kiyaa hai. ye n keval phones ko achchhaa look prdaan kar rahaa hai balki esse bahut hi naye features phone ko mil rahe hain. chunki ye OLED Display bahut hi kimti hai esalia eskaa estmaal abhi ke lia keval high end phones aur dusre Tech Gadgets men ho rahaa hai.
Ham men se bahuton ne to eske vishay men sunaa hogaa ki ye LED ka ek naya version hai Organic LED lekin kyaa aapko eske vishay men puri jaankaari hai. yadi nahin to kriapyaa mere saath bane rahiye aur es article ko puri tarah se pdhen, aakhir tak aapko OLED Display ke vishay men sampurn jaankaari praapt ho jaaagi. to phir binaa deri kiye chalia jaante hain ki aakhir ye OLED Display kya hai aur ye kisaprkaar se dusre LED se bhinn hai, to phir chalia shuru karte hain.
OLED kya Hai? (What is OLED in Hindi)
OLED kaa Full Form hotaa hai Organic Light Emitting Diodes. ye flat light emitting technology hoti hai. jise ki banaayaa jaataa hai series of organic thin films ko eksaath place kiyaa jaataa hai series men do conductors ke bich men. jab bhi unke bhitar se electric current ko pass kiyaa jaataa hai tab vo bright light emit karti hai. OLEDs emissive display hoti hai jinhen ki backlight ki koi jarurat nahin hoti hai, eske saath ye bahut hi patle hote hain aur LCD displays ke tulnaa men bahut jyada efficient hote hain.
OLED Displays na keval patle aur efficient hote hain balki ye sabse behatar image quality bhi provide karte hain. eske saath unhen transparent, flexiblefoldable aur rollablestretchable bhi banaayaa jaa saktaa hai bhavishy men. esalia OLED ko display technology kaa bhavishy bhi kahnaa galat nahin hogaa. ese chalaane ke lia bahut hi kam power ki jarurat hoti hai. OLED ka estmaal abhi smobile phones, martphones aur gaming devices men kiyaa jata hai.
History of OLED
Sabse pahle OLED device ko san 1987 men develop kiyaa gayaa tha Ching W. Tang aur Steven Van Slyke ke dvaaraa Eastman Kodak men. tab se lekar aaj tak OLED technology men kayi badlaav laaye jaa chuke hain, ese bahut baar improve bhi kiyaa jaa chukaa hai jisse ye bahut hi kam power ke estmaal se bahut effcient light prdaan kartaa hai.
OLED Technology kya hai
OLED panels organic (carbon based) materials se bane hua hote hain aur ye light emit tabhi karte hain jab enmen se electricity ko pass kiyaa jaataa hai. chunki OLEDs ko kisi backlight aur filters (jaise ki LCD displays men hoti hai), esalia ye jyaadaa efficient, banaane ke lia aasaan, aur bahut patle huaa karte hain – eske saath enhen aasaani se flexible aur rollable bhi kiyaa jaa saktaa hai. OLEDs men behatrin picture quality hoti hai – brilliant colors, infinite contrast, fast response rate aur wide viewing angles eske kuchh mukhy features hain. OLEDs kaa estmaal OLED Lighting ke lia bhi hotaa hai jahaan ki patle, efficient aur binaa kisi metals ke ese banaayaa jaa saktaa hai.
Working of OLEDs
OLED display kaa mukhy component hotaa hai OLED emitter – jo ki ek organic (carbon-based) material hotaa hai aur vo light emit tabhi kartaa hai jab usmen electricity apply ki jaati hai. ek OLED kaa Basic structure kuchh esaprkaar se hotaa hai ki jismen ek emissive layer ko sandwiched kiyaa jaataa hai ek cathode (jo ki electrons ko inject karti hai) aur ek anode (jo ki electrons ko remove karti hai) ke bich.OLEDs aam tor se conventional diodes aur LEDs ke tarah hi kaam karte hain, lekin yahaan n-type aur p-type semiconductors ke layers ko estmaal karne ke badle, organic molecules kaa estmaal kiyaa jaataa hai electrons aur holes ko produce karne ke lia. ek simple OLED six different layers se bani hui hoti hai. eske top aur bottom men protective glass or plastic layers hote hain . Top layer ko “seal” kaha jata hai aur bottom layer ko “substrate” kaha jata hai.
In layers ke bich, ek negative terminal (jise ki kabhi kabhi cathode kahaa jaataa hai) aur ek positive terminal (jise ki kabhi kabhi anode kahaa jaataa hai) hotaa hai. Finally, anode aur cathode ke bich two layers hote hain jinhen ki organic molecules se banaayaa gayaa hotaa hai jise ki emissive layer (jahaan ki light ko produce kiyaa jaataa hai, jo ki cathode ke bagal men hotaa hai) aur conductive layer (jo ki anode ke bagal men hotaa hai) kahaa jaataa hai. Modern OLED devices men bahut saare layers ka estmal hotaa hai, taaki enhen jyada efficient aur durable banaayaa jaa sake, lekin en sabhi ki basic functionality vahi saman rahti hai.
Kaise OLED Panel ko banaya jata hai
Ik OLED panel banaa hotaa hai ek substrate, backplane (electronics – the driver), frontplane aur ek encapsulation layer. OLEDs bahut hi sensitive hote hain oxygen aur moisture ke prati eske saath encapsulation layer bhi bahut critical hotaa hai.
Substrate aur backplane kisi bhi OLED display kaa bahut hi similar hotaa hai ek LCD display ke tarah, lekin front plane deposition bahut hi unique hotaa hai OLEDs kaa. bahut se tarike hote hain organice layers ko deposit aur pattern karne ke lia. abhi ke samay men praay sabhi OLED displays ko banaayaa jaataa hai vacuum evaporation ke dvaaraa, eske saath pattern karne ke lia Shadow Mask (FMM, Fine Metal Mask) kaa estmaal hotaa hai. ye bahut hi aasaan method hotaa hai lekin ye bahut hi inefficient (bahut saare materials yahaan par waste ho jaate hain) hotaa hai kyunki ese large substrate men scale up karna kathin hai.
Kuchh OLED materials soluble hote hain, aur ese printing methods ke estmaal se deposit kiyaa jaataa hai, yahaan ink-jet printing kaa estmaal kiyaa jaataa hai. es technology ko abhi tak commercialized nahin kiyaa gayaa hai, lekin OLED makers kaa maannaa hai ki ink-jet printing ko scalable, efficient aur cheap bhi kiyaa jaa saktaa hai taaki eskaa estmaal OLEDs ko deposit ke lia kiya ja sakta hai.
In OLEDs ko Organic kyun kahaa jaataa hai ?
OLEDs esalia organic hai kyunki vo carbon aur hydrogen se bane hua hote hain. lekin sach to ye hain ki enkaa organic food aur farming se koi rishtaa nahin hotaa hai – OLEDs to bahut hi efficient hote hi hai lekin uske saath esmen koi bhi bad metals kaa estmaal nahin hotaa hai – to ham ye jarur kah sakte hain ki ye sahi maaine men ek real green technology hai.
Kaise OLED Light Emit karte hain
Yahaan ye savaal aksar bahut logon ke dimaag men aataa hai ki kaise OLED se light utpann hotaa hai ? yahaan men aap logon ko esi ke vishay men puri jaankaari dene vaalaa hun.
1. Yadi ek OLED ko jalaanaa hai tab sabse pahle hamen use ek voltage source ke saath attach karnaa hogaa, jise ki anode aur cathode ke across lagaayaa jaataa hai.
2. Jaise hi electricity flow honaa aarambh hotaa hai, tab cathode receives kartaa hai electrons power source se aur anode unhen lose kartaa hai (or dusre njar se dekhe to ye “hole receives karte hain,”).
3. Ab hamre paas ek aisaa situation jahaan ki added electrons emissive layer ko negatively charged (jo ki similar hoti hai n-type layer jaise junction diode men) karte hain, lekin vahin conductive layer positively charged ban jaati hai (jo ki similar hoti hai p-type material jaise).
4. Positive holes bahut hi jyaadaa mobile hote hain negative electrons se esalia vo aasaani se jump kar lete hain boundary ke across conductive layer se emissive layer tak. jab ek hole (a lack of electron) meet kartaa hai ek electron se, ye donon chijen ek dusre ko cancel karti hain aur ek burst of energy ko release karti hain jo ki ek particle of light— jise ki photon bhi kahaa jaataa ke form men hoti hai. es process ko recombination bhi kahaa jaataa hai kyunki 1-second men kayi baar hotaa hai jisse OLED continuous light utpann karti hai jab tak ki current flow karti rahe.
Ham chaahen to OLED ko colored light paidaa karne ke lia banaa sakte hain jiske lia hamen ek colored filter ko plastic sandwich ke niche men stith glass or plastic top or bottom layer men rakhnaa hogaa. agar ham aise hi hajaaron ki sankhyaa men red, green, aur blue OLEDs ko ek dusre ke saath rakhenge aur unhen independently switch on aur off karenge tab vo pixels jo ki ek conventional LCD screen men hai vaise kaam karenge, jisse ham complex, hi-resolution colored pictures produce kar sakte hain.
Types of OLEDs
OLED ke mukhy do alag types hote hain.
1. Traditional OLEDs : jo ki chhote organic molecules kaa estmaal karte hain aur jinhen glass ke upar deposit kiyaa jaataa hai light paidaa karne ke lia.
2. Light-Emitting Polymers : ye dusre dharan ke OLED hote hain jo ki large plastic molecules jinhen ki polymers kahaa jaataa hai unkaa estmaal karte hain. en OLEDs ko light-emitting polymers (LEPs) bhi kahaa jaataa hai aur kabhi kabhi enhen polymer LEDs (PLEDs) bhi kahaa jaataa hai. chunki unhen plastic ke upar print kiyaa jaataa hai ( yahaan aksar ek modified, high-precision version kaa inkjet printer estmaal men laayaa jaataa hai) glass ki jagah men, jiske kaaran ye aur bhi patle aur jyaadaa flexible hote hain.
OLED ke Materials
Vaise dekhaa jaaye to OLED Materials ke bahut saare types hote hain. jo most basic division hotaa hai vo small-molecule OLEDs aur large molecule ones (jinhen ki Polymer OLEDs, or P-OLEDs) ke bhitar hotaa hai. aaj saare commercial OLEDs jo estmaal men laaye jaa rahe hain vo SM-OLED based hote hain. P-OLEDs kaa pahle khub naam thaa kyunki vo naturally solution processable (and so can easily be used in InkJet printing and spin-coating fabrication methods) hote the – lekin abhi P-OLEDs aur jyaadaa popular nahin hain kyunki unkaa performance ab SM-OLEDs ke jaise bilakul bhi nahin hai. bahut se Intensive research kiye jaa rahe hain taaki jyaadaa efficient solution-processable SM-OLEDs ko develop kiyaa jaa sake.
OLED emitter materials ko classify kiyaa jaa saktaa hai either fluorescent aur phosphorescent men. Fluorescent materials jyaadaa der tak tik ke rah sakte hain lekin vo jyaadaa efficient nahin hote hain phosphorescent materials ke tarah. abhi most OLED displays phosphorescent emitter materials kaa estmaal karte hain – lekin sirph blue color ko chhodkar jo ki ab bhi fluorescent hai jisse eski lifetime utni jyaadaa achchhi nahin hai. Universal Display Corporation abhi PHOLED ke upar research kar rahi hai, aur vo esi area men apnaa basic patents bhi hold kiyaa hai.
AMOLED vs PMOLED
Ye terms mukhy rup se OLED display ke driving method se related hain. ek PMOLED (Passive-Matrix OLED) hameshaa size aur resolution men limited hote hain, lekin ye bahut hi saste hote hain aur enhen banaanaa bahut hi aasaan hotaa hai agar ham AMOLED (ye Active-Matrix kaa estmaal karte hain) se compare karen tab.
Ek AMOLED hameshaa active-matrix TFT array aur storage capacitors kaa estmaal karte hain. dekhaa jaaye to ye displays bahut hi jyaadaa efficient hote hain aur enhen bdaa bhi banaayaa jaa saktaa hai, vahin enhen banaanaa bahut hi kathin kaam hai PMOLED ke tulnaa men.
PMOLED displays kaa estmaal hotaa hai small devices aur secondary displays vahin AMOLEDs kaa estmaal hotaa hai smartphones, tablets aur TVs men.
OLEDs ke advantages
OLEDs apne pratidvandvi LCDs se bahut se kaarnon men superior hain. yahaan mainne esi ke vishay men thodaa jaankaari prdaan ki hai.
Ye bahut hi patle hote hain.
Iske saath ye lighter bhi hote hain aur bahut jyaadaa flexible bhi hote hain.
Ye jyaadaa brighter hone ke kaaran enhen backlight ki koi jarurat nahin hoti hai.
Ye LCD ki tulnaa men bahut kam power consume karte hain. jisse enke estmaal se portable devices ki battery life achchhi hoti hai.
LCD ki tulnaa men enki refresh rate bahut jyaadaa hoti hai jisse aap yahaan achchhe tarike se fast-moving pictures dekh sakte hain.
Ye bde achchhe dhang se truer colors paidaa kar sakte hain aur vo bhi bde viewing angle ke saath.
Inhen banaane kaa karch bhi bahut kam hotaa hai LCD ke tulnaa men.
OLED bahut hi alag alag colors men upalabdh hai jisse ye bahut hi versatile hote hain.
Ismen start hone ke lia koi warm up period ki jarurat nahin hoti ye instantly start ho jaate hain.
Ye dimmable hote hain jisse enhen ambient lighting ke lia bhi estmaal kiyaa jaa saktaa hai.
Ye heat paidaa nahin karte hain jalne ke doraan esalia enhen cold lighting source bhi kahaa jaataa hai.
Inki efficiency level halogen aur incandescent lights se bhi jyaadaa hoti hai.
OLEDs ke disadvantages
Vaise ho OLEDs ke jyaadaa advantages hote hain lekin eske kuchh disadvantages bhi hain to chalia enke vishay men jaante hain.
Ye jyaadaa samay tak Last nahin karte hain kyunki esmen stith organic molecules dhire dhire khraab hone lagte hain.
Iske saath ye Water aur moisture ke prati bahut hi jyaadaa sensitive hote hain. chunki ye gharon men stith Tv sets men jyaadaa laagu nahin hotaa lekin ye asli challenge portable device (SmartPhones) men laataa hai.
Application of OLEDs
Jaise ki ham ye jaante hain ki OLEDs ki technology bahut hi nayi hai. enhen bahut hi kam jaghon men abhi estmaal men laayaa jaa rahaa hai. jahaan LCD aur LED ko log jyaadaa estmaal men laa rahe hain vahin esne abhi abhi hi Market men kadam rakhaa hai. phir bhi eske bahut se achchhe features hone ke kaaran hi ese abhi jyaadaa estmaal men laaye jaane lagaa hai.
OLED Display
Inhen bhi mukhy rup se Display ke tor par Mobile aur dusre electronic gadgets men estmaal kiyaa jaa rahaa hai.
Digital Watches
Kyunki enki weight bahut hi kam hoti hai, ye foldable bhi hoti hai, eske saath ye bahut hi kam power kaa estmaal karti hai esaliye enhen Apple ke Smart Watch men estmaal kiyaa jaa rahaa hai.
Smart Phones
Apple aur Samsung jaise bde companies ne OLED ko apne naye phones men estmaal kiyaa hai, kyunki ye n keval phones ko ek achchhaa look dete hain balki eske saath ye bahut saare features bhi prdaan karte hain.
OLED TV
Inkaa estmaal ab Television men bhi hone lagaa hai kyunki ye viewers ko truer colours prdaan karti hai aur eske saath wider viewing angle bhi jisse dekhne vaalon ko experience bahut hi achchhaa hotaa hai.
Mujhe purn aashaa hai ki mainne aap logon ko OLED kyaa hai? ke baare men puri jaankaari di aur men aashaa kartaa hun aap logon ko OLED kyaa hotaa hai ?ke baare men samajh aa gayaa hogaa. meraa aap sabhi paathkon se gujaaris hai ki aap log bhi es jaankaari ko apne aas-pdos, rishtedaaron, apne mitron men Share karen, jisse ki hamaare bich jaagruktaa hogi aur esse sabko bahut laabh hogaa. mujhe aap logon ki sahyog ki aavashyaktaa hai jisse main aur bhi nayi jaankaari aap logon tak pahunchaa sakun.
