PenTile ntawm txawb lub xov tooj puv npo LCD / AMOLED zaub tshuab

Jan 20, 2018

Raws li qhov puv npo tau ua tus qauv ntawm tus qauv xov tooj ntawm tes, nws yog ntau thiab ntau cuab kev. Thaum lub vijtsam loj dua thiab loj, qhov kev daws teebmeem dua thiab siab dua. Thaum yuav ib lub xov tooj ntawm tes, coob tus neeg xav tias qhov ntau dua qhov kev daws teeb meem, qhov tseeb ntau ntawm qhov kev tshwm sim ntawm kev tshuaj ntsuam yog. Qhov tseeb, lub tswv yim no tsis yog txhua yam. Cov khoom ntawm lub vijtsam thiab cov kev hloov ntawm subpixel tseem yog yam tseemceeb uas cuam tshuam rau cov vijtsam cov nyhuv. Qhov kev npaj ntawm sub pixels feem ntau muab faib ua ob pawg, ib qho yog tus qauv RGB, lwm tus yog RGB PenTile uake. Lawv txhais li cas? Uas cov noob pixel tuab si screen zoo dua? Kuv mam li muab koj teb rau tom ntej.


Lub hauv paus ntsiab lus ntawm cov ntaub ntawv, yog tsim los ntawm liab ntsuab xiav (RGB) RGB xim pixel parallel Kexem (Pixel), txhua yam xim yuav txawv ntawm RGB xim xim ntawm lub collocation ua, ntug kom pom yog peb cais strips ntawm lub teeb, tab sis cov pixels muaj tsawg heev, lub qhov muag zoo zoo nrug yog sib xyaw ntawm lub teeb xim lub. Qhov screen zaub yog tsim ntawm ntau pixels, thiab yuav kom txhua txhua ib zaug xwb pixel yuav qhia tau ntau yam xim, koj yuav tsum muab tso rau hauv peb RGB pixels dua ib qib qis sub pixel. Ntawd yog, 3 sub pixels tsim ib tug lej, uas yog, xim pixels. Thaum peb xav pom cov xim sib txawv, peb lub sub pixels muaj luminescent ntawm kev sib txawv. Vim tias qhov luaj li cas ntawm cov pixel me me, nws yuav tsum tau mus rau hauv cov xim yam hauv lub zeem muag.

Paub txog lub tswv yim ntawm sub-pixel, peb yuav nkag mus rau lub ntsiab lus ntawm hnub no - qhov kev npaj ntawm sub-pixel. Nws tau hais saum toj no tias tus qauv tsim ntawm sub-pixel faib ua ob hom, ib qho yog cov txwm RGB, lwm yog RGB PenTile uake. Muaj ob hom kev npaj twg?


Ob lo lus txhais ntawm noob pixel tshiab

RGB kev npaj

RGB Kev Txhim Kho Cov txheej txheem RGB yog cov txheej txheem tshaj plaws. Nws faib ib lub xwmfab zoo li pixel rau hauv peb qhov sib npaug zos, thiab txhua lub thaiv muab cov xim sib txawv, yog li ntawd nws tuaj yeem tsim ib daim xim pixel. Qhov no yog qhov siv LCD sub-pixel tshaj plaws txoj kev siv (ntawm chav kawm, peb qhov pixel sib lawv liag yog arbitrary, tsis yog hais txog "liab" lossis "blue red").

Yog li, ntev li ntev tau peb muab txaus pixels ntawm no tus qauv ua ke, peb tuaj yeem qhia cov qauv peb xav tau.

Nyob rau hauv qhov tseeb, feem ntau ntawm cov LCD, siv tus qauv RGB subpixel array. Qhov zoo ntawm nws yog tias pixel kev ywj siab yog siab, thiab txhua pixel yuav tso tag nrho cov xim rau nws tus kheej. Tab sis qhov teeb meem yog tias peb xav ua m * n saib. Peb yuav tsum ua 3m * n pixels. (nyob rau hauv cov txheej txheem tsim, sub-pixel yog cov khoom siv yooj yim tshaj plaws) Lawv tsis muaj xim thiab xim yog tsim los ntawm cov ntxaij lim dej). Qhov no tsis yog qhov teeb meem ntawm cov kua siv lead ua kua, vim LCD siv cov txheej txheem luam tawm, thiab pixels coob npaum li cas tsis muaj feem cuam tshuam rau cov nqi.


RGB PenTile array

PenTile yog qhov tsim muaj lub npe hu ua Clairvoyante lub tuam txhab ntawm San Francisco Silicon Valley tau tsim, vim tias nws cov kev cuam tshuam hauv RGB specifications, ntxiv rau RGB, ntxiv xim dawb sab nraum W (Dawb), thaum RGBW plaub-xim ua ywj siab pixel, nrog manipulation ntawm qhov chaw nyob (Addressable), yog li txhua lub xim yuav khiav lag luam ntawm nws tus kheej yog qhov PenTile. Thiab cov kab RGB, yog peb xim sib dhos ua ke los ua ib tug pixel, yog qhov yooj yim nyob ntawm chaw nyob, ntawm daim ntawv teev npe tsis tuaj yeem pom muaj xim ib leeg.


Thiab tam sim no, lub RGB PenTile tshiab yog tam sim no txoj kev los npaj ntau tus OLED - raws li RGB sub - pixels. Nws yog nrog tus qauv RGB tshiab ntawm ib qho pixel tsis zoo li qub, qhov pixel array yog li ntawm tus qauv RGB RGB peb lub pixels, thiab tib pixel PenTile tsuas yog "liab" lossis "xiav thiab ntsuab" ob sab pixels. Sab laug ntawm daim duab yog qhov subpixel kev hloov ntawm RGB PenTile uake. Raws li koj tau pom, tib lub teeb ntawm 3 x 3 pixels, RGB PenTile tsuas yog 6 sub pixels nyob hauv txoj kev taw qhia tav toj, thaum tus qauv RGB 9, thiab tus lej ntawm sub pixels yog txo los ntawm 1/3. Thaum twg cov duab no tshwm sim, ib lub pixels ntawm RGB PenTile yuav "qiv" rau peb xim nrog lwm cov xim ntawm nws cov uas nyob ib sab pixels. Nyob hauv txoj kab kev taw qhia, txhua lub pixel thiab cov pixels uas nyob ib sab sib qhia tawm pixels ntawm cov xim uas lawv tsis muaj, ua ke kom tiav ib qho dawb.

Qhov zoo ntawm PenTile

Cov duab nram qab no yog qhov txawv ntawm PenTile thiab cov qauv kev cai hauv kev siv tshuab. Cov kab ke RGB pixels yog teem rau txoj kev zoo thiab zoo ib yam. Raws li pom muaj hauv daim duab, muaj ib kab kab dawb tshwm. Tus RGB hauv txhua lub pixel yuav tig mus rau qhov ci tshaj plaws. Yuav tsum qhia kab dub, thiab RGB hauv lub pixel yuav tsum muab tua. PenTile tag nrho yog ib zaug xwb pixel, tau teem caij rau hauv checkerboard, vim yog tsis muaj correlation ntawm cov xim, ces txhua pixel tau chav nrog lwm yam pixel zaub, uas yog RGBW tuaj yeem ua ke ntawm cov xim dawb, xws li dawb thiab dawb lub cev tsuas yog tshwm sim los ntawm cov kab dub, thiab peb. (sab laug sab rau cov RGB zaub, cov kab ncaj nraim, cov kab teeb yog PenTile; txoj cai qauv, txoj kab ncaj ncaj, kab.)

Qhov loj tshaj plaws ntawm PenTile qauv yog lub zog txuag. Cov kua dej ua kom pom tseeb yog qhov tsawg heev, vim tias RGB lub teeb yog ua los ntawm cov lim, lim cov teeb pom kev rov qab, feem ntau yog 90%, peb tsuas pom ib feem me me ntawm lub teeb pom kev zoo dua, yog li nws zoo li maub . PenTile ua rau kom pom lub teeb dawb, yog lub teeb ntawm lub teeb nrob qaum ncaj qha, tsis tau lim, ces qhov ci ntsa iab yog siab heev, kev sib raug zoo ntawm tus txheeb ze yuav raug txo.


Tsis tas li ntawd, PenTile txhua pixel thiab collocation nyob ib sab pixel los ntawm cov kev cai RGB ntawm tib lub sij hawm txwv, thiab muaj peev xwm tsim ntawm ntau xim, tsis tas xim ua ke, xws li kab uas dawb collocation, xim zaub tsawg tshaj li cov xim xim, cov nyhuv yog tib yam. Qhov xim xim kom ua rau tag nrho vaj huam sib luag rau (tsis muaj pes tsawg tus pixels), RGBW xim thaiv Block PenTile, yuav raug txo los ntawm 1/3 dua li cov xim RGB xim, ces PenTile tau RGBW txhua qhov xim hla dej kom loj, pixel transmittance, thiaj li hais tias tag nrho cov vaj huam sib luag brightness nce. Ua ntej qhov kev kwv yees, dawb pixels plus pixel tsam magnification, tuaj yeem ua kom ob npaug ntawm lub vaj huam sib luag, yog tias qhov tseem ceeb ci, kev siv hluav taws xob tau txo los ntawm ib nrab.


Ntxiv nrog rau kho vajtse, PenTile kuj tau tsim kho ntau ntawm cov software. Txawm hais tias feem ntau ntawm cov PenTile zaub ntshiab thiab kajsiab, cov xim ntawm ib co duab yog saturated thiab tsis zoo. Lub sijhawm no, peb siv software los txo cov kev ci ci dawb pixels thiab kho lawv nrog lwm cov xim, ua cov duab ntuj. PenTile tsis ntev los no nyob rau ntawm lub rooj sib tham ntawm kev tshuaj ntsuam thiab kev nthuav tawm ntawm cov duab yeeb yaj kiab, nrog rau cov duab xim ntawm cov duab xim, los kho cov duab tom ntej, cia lub qhov muag saib cov duab tsis tau hloov, tab sis lub hwj chim zoo heev, kwv yees siv tam sim no plaub feem pua, tsib caug ntawm hluav taws xob, koj tuaj yeem saib tv.


Pentile sub pixels teem los ntawm cov uas nyob ib sab sub pixels simulate pixel, txoj kev opportunistic yuav txo qhov pes tsawg tus sub pixels, piv txwv li, ib qho screen pixel nrog lub cev RGB pixel yuav muaj tag nrho ntawm 15 lab sub pixels, tab sis yog yuav muaj tsuas yog 10 lab rau Pentile lub.


Qhov no yog qhov zoo tshaj plaws piv nrog GPU. Txo pes tsawg tus sub pixels tau ncaj qha txo cov load ntawm GPU. Qhov no tsis piav qhia tias netizen nyob rau hauv lub rooj sab laj tau nce qhov kev sib tw ntawm qhov kev ua si "hmoov av 3" rau 5760 * 1080, thiab tsuas yog 580SLI xwb thiaj li khiav tau.
