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 pakali pano, DC dimming sikoyenera, chifukwa chake ndi chakuti OLED ndi chophimba chodziwunikira chokha, pixel iliyonse imatulutsa kuwala payokha, ndipo kusintha kwa mphamvu yowunikira ya OLED kudzachitapo kanthu pa pixel iliyonse, chophimba cha 1080P ma pixel opitilira 2 miliyoni. Mphamvu ikachepa, kusinthasintha pang'ono kumayambitsa kuyatsa kosiyana kwa ma pixel osiyanasiyana, zomwe zimapangitsa kuwala ndi zovuta zamtundu. Izi ndi zomwe timatcha "Screen yozungulira".
Poganizira kusagwirizana kwa DC dimming mu OLED zowonetsera, mainjiniya apanga njira ya PWM ya dimming, imagwiritsa ntchito zotsalira za diso la munthu kuwongolera kuwala kwa chinsalu kudzera mukusintha kosalekeza kwa "screen-off screen-bright screen- off screen”.Kutalikitsa chinsalu chiyatsidwa pa nthawi ya unit, m'pamenenso kuwala kwake kumakwerachophimba,ndi mosemphanitsa.Koma njira ya dimming iyi ilinso ndi zofooka, kagwiritsidwe kake ka kuwala kochepa, kosavuta kuchititsa maso kukhumudwa.Pakali pano, 480Hz imagwiritsidwa ntchito kwambiri pakuwala kochepa kwa PWM m'makampani. Masomphenya aumunthu sangathe kuzindikira stroboscope pa 70Hz .Zikuoneka kuti kusintha pafupipafupi kwa 480Hz ndikokwanira, koma maselo athu owoneka amatha kumvabe stroboscope, iwo adzayendetsa minofu ya diso kuti isinthe.Izi zingayambitse kusokonezeka kwa maso pambuyo pogwiritsira ntchito nthawi yaitali.Njira ya Dimming ndi chinthu chofunika kwambiri chokhudzana ndi chitonthozo cha kugwiritsa ntchito chophimba, komanso ndi chimodzi mwazofukufuku zamakampani m'zaka ziwiri zapitazi. zaka.
