Nws zoo nkaus li tias cov xov tooj ntawm tes nrog cov ntxaij vab tshaus LCD tau dhau los ua qhov nyuaj nrhiav, tsawg kawg los ntawm qhov kev xav ntawm kev tiv thaiv ob lub qhov muag, qhov no yog undoubtedly ib tug khuv xim.
Thaum Lub Ntiaj Teb Qhov Muag Hnub (Lub Rau Hli 6), DxOMark tau tshaj tawm ib tsab xov xwm ntev uas qhia txog qhov teeb meem ntawm kev tshuaj ntsuam flickering.
Cias muab, vim li cas vim li cas LCD yog qhov muag tiv thaiv ntau dua li OLED yog tias nws yeej tsis ua rau qhov muag nkees vim flicker. Qhov laj thawj tseem ceeb yog vim li cas PWM dimming zaus ntawm LCD pib li ntawm 1000 Hz lossis siab dua, thaum lub vijtsam OLED Feem ntau tsuas yog 50 ~ 500 Hz.
DxOMark tau piav qhia tias tib neeg lub qhov muag muaj kev cuam tshuam rau flicker txog 250 Hz, yog li OLED cov ntxaij vab tshaus yuav ua rau lub qhov muag nkees dua li LCDs.
DxOMark tau hais tias txawm tias cov neeg uas tsis nco qab pom qhov flicker tuaj yeem ua rau nws, xws li mob taub hau lossis qhov muag nkees tom qab siv lub vijtsam ntau dhau. Cov neeg no tuaj yeem yuav cov smartphones nrog LCD cov ntxaij vab tshaus es tsis txhob OLED cov ntxaij vab tshaus.
DxOMark ntsuas hauv chav kuaj kev tshaj lij, PWM zaus ntawm Xiaomi 10T Pro (Redmi K30S Extreme Edition) nruab nrog LCD npo mus txog 2360Hz, thaum Samsung S20U tsuas muaj 241Hz thiab Huawei P40 Pro tsuas yog 362Hz.
Tsis tas li ntawd, thaum lub teeb ci ntawm OLED screen tsawg heev, lub voj voog ua haujlwm (lub sijhawm ntawm LED teeb pom kev zoo nyob rau hauv ib lub voj voog yog hu ua lub voj voog lub luag haujlwm) yog luv heev, thiab lub flicker yuav pom tseeb dua ntawm qis dua PWM zaus. Nws tuaj yeem piav qhia yog vim li cas nyeem ntawv lossis saib cov yeeb yaj kiab hauv txaj thaum hmo ntuj yog qhov ua rau mob taub hau thiab qhov muag nkees ntau dua li thaum saib lub vijtsam hauv qhov ci ntsa iab.
PWM lub voj voog ua haujlwm ntawm 25 feem pua, 50 feem pua, 75 feem pua thiab 100 feem pua perceptual brightness theem
