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 kunyatsokodzera, chikonzero ndechekuti OLED inovhenekera skrini, pixel yega yega inoburitsa mwenje yakazvimiririra, uye kugadzirisa kweOLED skrini inopenya simba ichaita zvakananga pane yega pixel, 1080P skrini ine anopfuura 2 miriyoni pixels. Kana simba rakaderera, kushanduka kudiki kudiki kunokonzeresa kusaenzana kwemavara kunokonzeresa kusaenzana kwepikiseli inokonzeresa. "Rag screen".
Iine chinangwa chekusapindirana kweDC dimming muOLED skrini, mainjiniya vakagadzira PWM dimming method, inoshandisa zvinoonekwa zvakasara zveziso remunhu kudzora kupenya kwescreen kuburikidza nekuenderera mberi kwekuchinjana kwe "bright screen-off screen-bright screen-off screen"skrini,uye zvakasiyana.Asi nzira iyi yekudzima inewo kukanganisa, kushandiswa kwayo mukupenya kwakaderera, nyore kukonzera kusagadzikana kwemaziso.Parizvino, 480Hz inowanzoshandiswa mukupenya kwakaderera kwePWM kuderera mumhizha.Kuona kwevanhu hakugoni kuona stroboscope pa70Hz.Zvinoita sekuti switching frequency ye 48Hz yekuona masero inoramba ichikwana,00Hz yekuona scope inoramba ichikwana 48Hz masero ekuona. ivo vachatyaira misumbu yeziso kuti igadzirise.Izvi zvinogona kutungamirira kukusagadzikana kweziso mushure mekushandisa kwenguva refu.Dimming nzira chinhu chinokosha chine chokuita nekunyaradza kwekushandiswa kwekrini, uye ihwowo humwe hunonyanya kukoshesa tsvakurudzo yeindasitiri mumakore maviri apfuura.
