Kodi DC dimming ndi PWM ndi chiyani? Ubwino ndi kuipa kwa CD dimming ndi OLED ndi PWM dimming?
Za kuChithunzi cha LCD, chifukwa imagwiritsa ntchito mawonekedwe a backlight, kotero kuwongolera mwachindunji kuwala kwa backlight layer kuti kuchepetsa mphamvu ya backlight layer kumatha kusintha kuwala kwa skrini, njira yosinthira yowala iyi ndi DC dimming.
Koma kwa mkulu-mapetoZithunzi za OLEDzomwe zimagwiritsidwa ntchito pakalipano, DC dimming sikoyenera, chifukwa chake ndi chakuti OLED ndi chophimba chodziwunikira, pixel iliyonse imatulutsa kuwala paokha, ndipo kusintha kwa mphamvu yowala ya mawonekedwe a OLED kudzachitapo kanthu pa pixel iliyonse, chophimba cha 1080P chimakhala ndi ma pixel oposa 2 miliyoni. "Screen"
Poganizira kusagwirizana kwa DC dimming mu OLED zowonetsera, akatswiri apanga njira ya PWM ya dimming, imagwiritsa ntchito zotsalira zowoneka za diso la munthu kuwongolera kuwala kwa chinsalu kudzera mukusintha kosalekeza kwa "screen-off screen-bright screen-off screen".chophimba,ndi mosemphanitsa.Koma njira ya dimming iyi ilinso ndi zofooka, ntchito yake yowala pang'ono, yosavuta kukhumudwitsa maso.Pakali pano, 480Hz imagwiritsidwa ntchito poyang'ana pang'onopang'ono PWM yocheperako m'makampani. Masomphenya aumunthu sangathe kuzindikira stroboscope pa 70Hz. iwo adzayendetsa minofu ya diso kuti isinthe.Izi zingayambitse kusokonezeka kwa diso pambuyo pogwiritsira ntchito nthawi yayitali.Njira ya Dimming ndi chinthu chofunika kwambiri chokhudzana ndi chitonthozo cha kugwiritsira ntchito chophimba, komanso ndi chimodzi mwazofukufuku zamakampani m'zaka ziwiri zapitazi.
