Yini i-DC dimming ne-PWM dimming? Ubuhle nobubi be-CD dimming ne-OLED ne-PWM dimming?
OkweIsikrini se-LCD, ngoba isebenzisa isendlalelo se-backlight, ngakho-ke lawula ngokuqondile ukukhanya kwesendlalelo se-backlight ukuze unciphise amandla we-backlight layer kungalungisa kalula ukukhanya kwesikrini, le ndlela yokulungiswa kokukhanya i-DC dimming.
Kodwa okusezingeni eliphezuluIzikrini ze-OLEDesetshenziswa kakhulu njengamanje, i-DC dimming ayifaneleki kangako, isizathu ukuthi i-OLED iyisikrini esizikhanyisayo, i-pixel ngayinye ikhipha ukukhanya ngokuzimela, futhi ukulungiswa kwamandla akhanyayo esikrini se-OLED kuzosebenza ngokuqondile kuphikseli ngayinye, isikrini se-1080P amaphikseli angaphezu kwezigidi ezi-2. Uma amandla ephansi, ukushintshashintsha kancane kuzodala ukukhanya okungalingani kwamaphikseli ahlukene, okuholela ekukhanyeni nezinkinga zombala. Yilokhu esikubiza ngokuthi "isikrini se-rag".
Ngokuhloswe ukungahambisani kokufiphala kwe-DC kuzikrini ze-OLED, onjiniyela benze indlela yokufiphalisa ye-PWM, isebenzisa insalela ebonakalayo yeso lomuntu ukulawula ukukhanya kwesikrini ngokushintshana okuqhubekayo “kwesikrini esikhanyayo esivala isikrini esikhanyayo- off screen”.Uma isikrini sivulwa isikhathi eside ngeyunithi ngayinye, kulapho ukukhanya kuphezulu khonaisikrini,kanye nokuphambene.Kodwa le ndlela yokufiphaza ibuye ibe nokushiyeka, ukusetshenziswa kwayo ekukhanyeni okuphansi, kulula ukubangela ukungaphatheki kahle kwamehlo.Okwamanje, i-480Hz ivame ukusetshenziswa ekufiphaleni okuphansi kwe-PWM embonini.Umbono womuntu awukwazi ukubona i-stroboscope ku-70Hz .Kubonakala sengathi imvamisa yokushintsha engu-480Hz yanele, kodwa amaseli ethu abonakalayo asakwazi ukuzwa i-stroboscope, ngakho-ke bazoshayela izicubu zeso ukuze zilungise.Lokhu kungaholela ekuphathekeni kwamehlo ngemva kokusetshenziswa isikhathi eside.Indlela yokufiphala iyisici esibalulekile esihlobene nokunethezeka kokusetshenziswa kwesikrini, futhi ingenye yezinto okugxilwe kuzo ucwaningo lwemboni eminyakeni emibili edlule. iminyaka.
