OLED, LED, LCD, Inokunda uye Inorasikirwa?

Kana 2018 iri gore rehunyanzvi hwekuratidzira tekinoroji, haisi yekuwedzeredza.Ultra HD 4K inoramba iri yakajairwa kugadzirisa muindasitiri yeTV.High dynamic range (HDR) haisisiri chinhu chikuru chinotevera nekuti yakatoitwa.Izvi zvakafanana kune zvikwangwani zve smartphone, izvo zviri kuramba zvichiwedzera kujeka nekuda kwekuwedzera kwekugadzirisa uye pixel density pa inch.

Asi kune ese matsva maficha, isu tinofanirwa kufunga zvakadzama mutsauko uripo pakati pemhando mbiri dzekuratidzira.Mhando mbiri dzekuratidzira dzinoonekwa pamamonitor, terevhizheni, nharembozha, makamera, uye chero chero chimwe chidzitiro chidzitiro.

Imwe yacho ndeye LED (Chiedza Emitting Diode).Ndiyo mhando yakajairika yekuratidzira pamusika nhasi uye ine akasiyana matekinoroji.Nekudaro, iwe unogona kunge usiri kujairana nemhando iyi yekuratidzira nekuti yakafanana neLCD (Liquid Crystal Display) label.Iyo LED neLCD zvakafanana maererano nekushandiswa kwekuratidzira.Kana "LED" skrini yakanyorwa paTV kana smartphone, inenge iri LCD skrini.Icho chikamu che LED chinoreva chete kune mwenje sosi, kwete iyo inoratidza pachayo.

Mukuwedzera, iOLED (Organic Light Emitting Diode), iyo inonyanya kushandiswa mumafoni epamusoro-soro akadai se iPhone X uye ichangoburwa iPhone XS.

Parizvino, zviratidziro zveOLED zviri kuyerera zvishoma nezvishoma kuenda kumafoni epamusoro-soro eAroid, akadai seGoogle Pixel 3, uye maTV epamusoro akadai seLG C8.

Dambudziko nderekuti iyi ndiyo yakasiyana zvachose yekuratidzira tekinoroji.Vamwe vanhu vanoti OLED mumiriri weramangwana, asi zviri nani here kupfuura LCD?Zvadaro, ndapota teveraTopfoisonkuwana.Pazasi, isu ticharatidza mutsauko uripo pakati peaya maviri ekuratidzira matekinoroji, iwo mabhenefiti akasiyana uye misimboti yekushanda.

Musiyano

Muchidimbu, maLED, maLCD skrini anoshandisa mwenje yekumashure kuvhenekera mapixels avo, nepo OLED pixels ari kunyatsozvivhenekera.Iwe unogona kunge wakanzwa kuti OLED pixels inonzi "self-illumination" uye LCD tekinoroji "inotapurirana".

Chiedza chinoburitswa neOLED kuratidza chinogona kudzorwa pixel nepixel.LED liquid crystal inoratidzira haigone kugonesa kushanduka uku, asi ivo vanewo zvakaipira, izvoTopfoisonachasuma pazasi.

Mumutengo wakaderera weTV neLCD mafoni, ma LED emvura ekristaro anoratidza anowanzo kushandisa "kupenya mwenje" uko ma LED anowanikwa padivi pechiratidziro kwete kumashure.Zvadaro, chiedza chinobva ku LED idzi chinobudiswa kuburikidza nematrix, uye tinoona mapikseli akasiyana akadai setsvuku, girini, uye bhuruu.

Kupenya

LED, LCD skrini inopenya kupfuura OLED.Iri idambudziko hombe muindasitiri yeTV, kunyanya kune mafoni akangwara anowanzo shandiswa kunze, muchiedza chezuva.

Kupenya kunowanzoyerwa maererano ne "nits" uye kunenge kupenya kwekenduru paskweya mita.Iyo yakajairika peak kupenya kweiyo iPhone X ine OLED i625 nits, nepo LG G7 ine LCD inogona kuwana kupenya kwepamusoro kwe1000 nits.Kune maTV, kupenya kwakatokwira: Samsung's OLED TVs inogona kuwana kupenya kweanopfuura mazana maviri nits.

Kupenya kwakakosha kana uchiona zvemukati zvevhidhiyo mune ambient chiedza kana chiedza chezuva, pamwe nepamusoro dhidhiyo yemhando yepamusoro.Kuita uku kunonyanya kukodzera kuTV, asi sezvo vagadziri venharembozha vachiwedzera kuzvirumbidza nekuita kwevhidhiyo, kupenya kwakakoshawo mumusika uyu.Iyo yakakwirira yekupenya mwero, iyo yakakura iyo yekuona maitiro, asi hafu chete yeHDR.

Kusiyanisa

Kana iwe ukaisa LCD skrini muimba ine rima, unogona kuona kuti zvimwe zvikamu zvemufananidzo mutema wakasimba hazvina kusviba, sezvo chiedza chekumashure (kana kumucheto) chinogona kuonekwa.

Kukwanisa kuona malights asingadiwe anogona kukanganisa kusiyana kweTV, inovawo mutsauko pakati pezvinopenya zvakanyanya uye mimvuri yakasviba.Semushandisi, iwe unogona kazhinji kuona mutsauko unotsanangurwa mune zvigadzirwa, kunyanya zveTV uye mamonitor.Musiyano uyu ndewekuratidza kuti kupenya kwakadii kwemavara machena emonitor inofananidzwa nemuvara wayo mutema.Chidzitiro cheLCD chine hunhu chinogona kunge chine reshiyo yekusiyanisa ye1000:1, zvinoreva kuti chena inopenya zvakapetwa churu pane dema.

Kusiyana kweOLED kuratidzwa kwakakwira zvakanyanya.Kana iyo OLED skrini ikaita dema, mapikseli ayo haaburitse chero mwenje.Izvi zvinoreva kuti iwe unowana mutsauko usingagumi, kunyangwe chitarisiko chayo chinotaridzika zvakanaka zvichienderana nekupenya kwe LED kana yakabatidzwa.

Maonero

OLED mapaneru ane akanakisa ekuona makona, kunyanya nekuti tekinoroji yakatetepa uye mapikseli ari padyo nepamusoro.Izvi zvinoreva kuti iwe unogona kufamba uchitenderedza OLED TV kana kumira munzvimbo dzakasiyana dzeimba yekutandarira uye kuona skrini zvakajeka.Kune mafoni efoni, kona yekuona yakakosha zvikuru, nokuti foni haizove yakanyatsoenderana nechiso kana ichishandiswa.

Iyo kona yekuona muLCD kazhinji haina kunaka, asi izvi zvinosiyana zvakanyanya zvichienderana nehunyanzvi hwekuratidzira hunoshandiswa.Parizvino kune akawanda akasiyana marudzi eLCD mapaneru pamusika.

Zvichida inonyanya kukosha ndeye yakamonyoroka nematic (TN).Iyi tekinoroji inowanzoshandiswa mumakomputa akaderera-magumo, malaptops asingadhure, uye mamwe mafoni anodhura zvakanyanya.Maonero ayo anowanzova asina kunaka.Kana iwe wakamboona kuti komputa skrini inotaridzika semumvuri kubva kune imwe kona, saka ingangove yakamonyoroka nematic panel.

Sezvineiwo, akawanda maLCD madivayiri parizvino anoshandisa IPS pani.IPS (Plane Conversion) parizvino ndiye mambo wekristaro mapaneru uye anowanzo kupa zvirinani kuita kwemavara uye yakagadziridzwa yekuona kona.IPS inoshandiswa mune akawanda mafoni uye mahwendefa, nhamba huru yemakomputa monitors uye terevhizheni.Izvo zvakakosha kucherechedza kuti IPS neLED LCD hazvisi zvakasarudzika, imwe mhinduro.

Color

Iyo yazvino LCD skrini inoburitsa yakanakisa mavara echisikigo.Nekudaro, semaonero, zvinoenderana neiyo tekinoroji inoshandiswa.

Iyo IPS uye VA (Vertical Alignment) zviratidziro zvinopa kunaka kweruvara kwakaringana kana yakakwenenzverwa, nepo TN skrini kazhinji isingaratidzike zvakanaka.

Rudzi rweOLED haruna dambudziko iri, asi maOLED TV ekutanga uye nharembozha zvine matambudziko mukudzora ruvara uye kutendeka.Nhasi, mamiriro aita nani, sePanasonic FZ952 akatevedzana eOLED TVs kunyangwe eHollywood color grading studios.

Dambudziko neOLED uwandu hwemavara.Ndokureva kuti, chiitiko chinopenya chinogona kukanganisa kugona kweOLED pani kuchengetedza kuzara kwemavara.
