Nyob rau hauv xyoo tas los no, lubOLED npotau dav dav hauv kev lag luam xov tooj ntawm tes, qhov no undoubtedly tau txais txiaj ntsig los ntawm nws qhov txiaj ntsig loj tshaj plaws, uas tsis muaj lub teeb pom kev zoo, hluav taws xob tuaj yeem teeb pom kev zoo, lub kaum sab xis dav, qhov sib txawv siab, qis zog noj, ceev teb thiab dav xim gamut, txheej txheem yooj yim, thiab lwm yam. tau hais tias yog kev ua lag luam nyob rau tam sim no cov cuab yeej tso tawm tshiab, thiab feem ntau ntawm cov xov tooj ntawm tes siv OLED npo.
Cov ntxaij vab tshaus LCD siv LED backlight txheej, uas yuav tsum tau kho qhov ci ntawm lub vijtsam los ntawm kev hloov lub teeb rov qab tam sim no (thaum muaj qhov ci ntsa iab siab, qhov tam sim no yuav tsum tau nce, thiab thaum lub teeb ci qis, qhov tam sim no raug txo). Txoj kev hloov ci ci no yog DC dimming, tseem hu ua DC dimming. Thaum ntxov Samsung AMOLED cov ntxaij vab tshaus sim tag nrho DC dimming, tab sis vim yog cov txheej txheem tsim khoom, nws nyuaj rau ua tiav tib lub zog hluav taws xob ntawm txhua pixel. Nyob rau hauv qhov qis qis, raws li qhov tam sim no txo qis, qhov hluav taws xob sib txawv ntawm txhua pixel yuav raug qhia. Yog li ntawd, qhov kev ua tau zoo ntawm AMOLED siv DC dimming hom tsis zoo ntawm qhov ci qis, uas ua rau ntau lub AMOLED screen manufacturers thiab cov chaw tsim khoom lag luam kom ruaj khov xaiv lub tswv yim tshiab dimming, uas yog PWM dimming. Nyob rau hauv lub tswv yim PWM dimming, qhov ci thiab xim kub ntawm lub vijtsam tsis ua tiav los ntawm kev hloov lub ci ci ntawm pixels, tab sis los ntawm kev hloov lub sijhawm luminous ntawm pixels, uas zoo heev zam qhov teeb meem ntawm qhov sib txawv ntawm cov hluav taws xob loj ntawm pixels tseem ceeb vim qhov txo tam sim no, thiab zoo heev txhim kho cov nyhuv ntawm AMOLED nyob rau hauv qis brightness.
PWM is pulse width modulation. Kev tswj ntawm lub vijtsam ci ci yog qhov ua tau raws li qhov pom ntawm qhov pom ntawm tib neeg lub qhov muag. Lub hauv paus ntsiab lus yog tias nyob rau hauv cov xwm txheej uas tag nrho OLED pixel units tuav lub zog tso saib siab, qhov ci ntsa iab thiab tsaus ntuj tuaj yeem pom tau los ntawm kev hloov ntawm lub vijtsam mus rau qhov screen. Ntau tus neeg tsis ntseeg tias qhov flicker tsim los ntawm "rau thiab tawm" yuav ua rau tib neeg lub qhov muag puas tsuaj. Qhov tseeb, vim hais tias tib neeg lub qhov muag tau txais kev txhawb zog qis qis rau lub sijhawm ntev, nws yooj yim los tsim kom pom kev qaug zog, uas yuav ua rau tsis xis nyob rau lub qhov muag thiab txawm lub cev. IEEE Society of Engineers taw qhia tias tsis yog txhua tus PWM dimmers ua rau qhov muag puas. Thaum lub flicker zaus tshaj 1250Hz, qhov cuam tshuam ntawm tib neeg lub qhov muag tau txo qis heev. Yog li ntawd, high-frequency PWM tsis tsuas yog muaj qhov zoo ntawm DC dimming low brightness zaub nyhuv tsis zoo, tab sis kuj kov yeej qhov teeb meem ntawm tsawg zaus PWM dimming yooj yim ua rau pom kev qaug zog, uas tuaj yeem hu ua tus khub zoo tshaj plaws ntawm OLED screen.
Tam sim no, ntau thiab ntau lub tuam txhab tseem ceeb tau xaiv los nqa cov tshuab PWM dimming siab kom ua tiav cov kev teeb tsa siab kawg, xws li Huawei P50 E, Honour tshiab tshuab Magic4 series, Redmi K50 esports version thiab lwm yam yog siv PWM dimming. Redmi K50 e-kev ua si ib tsab yog nruab nrog tam sim no PWM siab tshaj plaws stroboscope 1920Hz siab zaus dimming, theem kho ntawm cov pa 480Hz, cov neeg siv kev paub tau zoo heev. Tsis tas li ntawd, Display Mate A + nrog 15 cov ntaub ntawv tshuaj ntsuam yog qhov tsis ntseeg qhov pov thawj zoo tshaj plaws ntawm Tuam Tshoj lub vijtsam sab saum toj. Qhov kev hloov pauv ncaj ncaj no yog tsim los ntawm TCL Huaxing, ua TCL Huaxing tib lub chaw tsim khoom hauv Suav teb kom dhau daim ntawv pov thawj no.
Contrary rau thawj qhov kev xav ntawm cov ntxaij vab tshaus hauv tsev, lawv tau tshwm sim muaj zog nyob rau hauv xyoo tas los no thiab tau nrawm nrawm nrawm hauv kev lag luam thoob ntiaj teb. Raws li ib qho ntawm cov ua OLED hloov tau yooj yim cov khoom lag luam, TCL Huaxing tau mus txog qhov tob hauv kev koom tes nrog ntau lub tuam txhab ua lag luam los ntawm kev tsim txiaj ntawm nws cov khoom siv zog thiab cov khoom muaj zog. Raws li tsab ntawv ceeb toom, LUB 1,954 PCT thoob ntiaj teb patents tso tawm los ntawm TCL Huoxing nyob rau hauv 2021 ranked 8th nyob rau hauv cov npe ntawm PCT thoob ntiaj teb patents tso tawm los ntawm thoob ntiaj teb cov lag luam nyob rau hauv 2021, thiab thib 4 nyob rau hauv Tuam Tshoj nyob rau hauv 2021, ua rau tag nrho cov kev lag luam. Tam sim no, TCL Huaxing tab tom tsim cov tswv yim tshiab thev naus laus zis xws li multi-fold screen, zawv zawg screen thiab pob tshab npo los xyuas kom meej nws txoj haujlwm tseem ceeb hauv cov thev naus laus zis. Hais txog cov khoom lag luam, nws yuav tsim cov txheej txheem sib txawv hauv kev siv sib txawv los muab cov neeg siv khoom sib tw ntau dua. Nyob rau hauv lub neej yav tom ntej, peb kuj cia siab tias yuav muaj ntau thiab ntau "tseeb fragrance" technology coj los rau peb los ntawm Suav creation.
