Chii chinonzi DC dimming uye PWM dimming?Zvakanakira nekuipa kweCD dimming uye OLED nePWM dimming?
For theLCD skrini,nekuti inoshandisa iyo backlight layer, saka inodzora zvakananga kupenya kweiyo backlight layer kuti ideredze simba rebacklight layer inogona kugadzirisa kupenya kwescreen, iyi nzira yekugadzirisa kupenya ndeye DC dimming.
Asi nokuda kwepamusoro-soroOLED skriniinowanzoshandiswa parizvino, DC dimming haina kufanira kudaro, chikonzero ndechekuti OLED chidzitiro chinozvivhenekera, pixel yega yega inoburitsa mwenje yakazvimiririra, uye kugadzirisa kweOLED kupenya kwesimba kuchaita zvakananga pane yega pixel, 1080P skrini ine. mapixels anopfuura mamiriyoni maviri. Kana simba racho rakaderera, kushanduka kuduku kuchaita kuti chiedza chisina kuenzana chepixels yakasiyana-siyana, zvichiita kuti kupenya uye matambudziko emavara.Izvi ndizvo zvatinodaidza kuti "rag screen".
Iine chinangwa chekusapindirana kweDC dimming mumaOLED skrini, mainjiniya akagadzira nzira yePWM dimming, inoshandisa zvakasara zvinoonekwa zveziso remunhu kudzora kupenya kwescreen kuburikidza nekuenderera kuchinjika kwe "bright screen-off screen-bright screen- off screen”.Kurebesa chidzitiro chichibatidzwa panguva imwe neimwe, ndiko kunowedzera kupenya kweskrini,uye zvakapesana.Asi nzira iyi yekudzima inewo kukanganisa,kushandiswa kwayo mukupenya kwakaderera,zviri nyore kukonzera kusagadzikana kwemaziso.Parizvino,480Hz inowanzoshandiswa mukupenya kwakaderera PWM kudzima muindasitiri.Kuona kwevanhu hakugone kuona stroboscope pa70Hz .Zvinoita sokuti kuchinja kwekuchinja kwe480Hz kwakakwana, asi masero edu ekuona anogona achiri kunzwa stroboscope, saka anotyaira misumbu yeziso kugadzirisa.Izvi zvinogona kutungamirira kukusagadzikana kweziso mushure mekushandisa kwenguva refu.Dimming nzira chinhu chinokosha chakabatana. kune kunyaradzwa kwekushandisa skrini, uye zvakare ndeimwe yezvinotariswa neindasitiri yekutsvaga mumakore maviri apfuura.
