Yintoni i-DC dimming kunye ne-PWM dimming? Izinto eziluncedo kunye nezingeloncedo ze-CD dimming kunye ne-OLED kunye ne-PWM dimming?
Ukwenzela iIsikrini se-LCD, kuba isebenzisa umaleko we-backlight, ngoko ke lawula ngokuthe ngqo ukuqaqamba komqolo we-backlight ukunciphisa amandla ombane we-backlight unokulungelelanisa ngokulula ukuqaqamba kwesikrini, le ndlela yohlengahlengiso lokukhanya yi-DC dimming.
Kodwa kwizinga eliphezuluIzikrini ze-OLEDngokuqhelekileyo isetyenziswa ngoku, ukufiphala kwe-DC akufanelekanga kangako, isizathu kukuba i-OLED sisikrini esizikhanyisayo, ipixel nganye ikhupha ukukhanya ngokuzimeleyo, kwaye uhlengahlengiso lwamandla akhanyayo esikrini se-OLED kuya kusebenza ngokuthe ngqo kwi-pixel nganye, isikrini se-1080P sinalo. ngaphezu kwezigidi ezi-2 pixels.Xa amandla ephantsi, ukuguquguquka okuncinci kuya kubangela ukukhanya okungalinganiyo kweepikseli ezahlukeneyo, okukhokelela ekukhanyeni kunye neengxaki zombala.Le yinto esiyibiza ngokuthi "i-rag screen".
Ijolise ekungahambelani kwe-DC dimming kwizikrini ze-OLED, iinjineli ziye zaphuhlisa indlela yobumnyama ye-PWM, isebenzisa intsalela ebonwayo yeliso lomntu ukulawula ukuqaqamba kwesikrini ngokutshintshana okuqhubekayo "kwesikrini esikhanyayo-isikrini-esikhanyayo-isikrini esikhanyayo- cima isikrini”.Okukhona isikrini sivulwa ixesha elide ngeyunithi nganye, kokukhona ukuqaqamba kuphezuluisikrini,kwaye ngokuphambeneyo.Kodwa le ndlela yobumnyama nayo ineziphene, ukusetyenziswa kwayo ekukhanyeni okuphantsi, kulula ukubangela ukungahambi kakuhle kwamehlo.Okwangoku, i-480Hz isetyenziswa ngokuqhelekileyo ekukhanyeni okuphantsi kwe-PWM ebumnyama kushishino.Umbono womntu awukwazi ukubona i-stroboscope kwi-70Hz .Kubonakala ngathi i-frequency switching ye-480Hz yanele, kodwa iiseli zethu ezibonakalayo ziyakwazi ukuva i-stroboscope, ngoko ziya kuqhuba izihlunu zamehlo ukuba zilungelelanise.Oku kunokukhokelela ekukhathazeni kwamehlo emva kokusetyenziswa ixesha elide.Indlela yokuDimming yinto ebalulekileyo ehambelanayo. Ukuthuthuzela ukusetyenziswa kwesikrini, kwaye yenye yezinto ekugxilwe kuzo kuphando lweshishini kule minyaka mibini idlulileyo.
