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 kweepixels ezahlukeneyo, okukhokelela ekukhanyeni kunye neengxaki zombala. "isikrini se-rag".
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 zisengaziva i-stroboscope, ngoko baya kuqhuba izihlunu zamehlo ukuba zilungelelanise.Oku kunokukhokelela ekubandezelekeni kwamehlo emva kokusetyenziswa kwexesha elide.Indlela yokunciphisa i-dimming yinto ebalulekileyo ehambelana nokuthuthuzela kokusetyenziswa kwesikrini, kwaye kungenye yezinto ezigxininiswe kuphando lweshishini kwixesha elidlulileyo. iminyaka.
