Qhov nce ntawm OLED, high-frequency PWM dimming breakthrough mus rau 2160Hz

Dab tsi yog DC dimming thiab PWM dimming? Qhov zoo thiab qhov tsis zoo ntawm CD dimming thiab OLED thiab PWM dimming?

Rau qhovLCD npo, vim hais tias nws siv lub backlight txheej, yog li ncaj qha tswj lub brightness ntawm lub backlight txheej kom txo lub hwj chim ntawm lub backlight txheej tau yooj yim kho qhov screen brightness, no brightness hloov txoj kev yog DC dimming.

Tab sis rau high-endOLED cov ntxaij vab tshausFeem ntau siv tam sim no, DC dimming tsis haum, yog vim li cas OLED yog lub teeb pom kev ntawm tus kheej, txhua pixel emits lub teeb ntawm nws tus kheej, thiab kev hloov kho ntawm OLED lub teeb lub zog yuav ua ncaj qha rau txhua pixel, 1080P npo muaj ntau dua 2 lab pixels.Thaum lub hwj chim qis, qhov hloov pauv me ntsis yuav ua rau cov teeb pom kev sib txawv ntawm cov xim sib txawv. hu rau "rag screen".

Lub hom phiaj ntawm qhov tsis sib haum xeeb ntawm DC dimming hauv OLED cov ntxaij vab tshaus, engineers tau tsim PWM dimming txoj kev, nws siv qhov pom qhov seem ntawm tib neeg lub qhov muag los tswj qhov ci ntawm lub vijtsam los ntawm kev hloov mus tas li ntawm "ci ntsa iab-tawm screen-ci ntsa iab screen-off screen".npo, thiab vice versa.Tab sis txoj kev dimming no kuj muaj shortcomings, nws siv nyob rau hauv tsawg brightness, yooj yim ua rau lub qhov muag tsis xis nyob.Tam sim no, 480Hz yog feem ntau siv nyob rau hauv low-brightness PWM dimming nyob rau hauv kev lag luam. Tib neeg lub zeem muag tsis pom stroboscope ntawm 70Hz.Nws zoo nkaus li hais tias lub switching zaus ntawm 480 Hz, peb lub hlwb tseem yuav txaus, tab sis bo strocopes yuav txaus. tsav cov leeg ntawm lub qhov muag kom kho.Qhov no tuaj yeem ua rau qhov muag tsis xis nyob tom qab siv ntev.Dimming txoj kev yog ib qho tseem ceeb uas cuam tshuam rau kev nplij siab ntawm kev siv tshuaj ntsuam, thiab nws kuj yog ib qho ntawm cov kev tshawb fawb kev lag luam hauv ob xyoos dhau los.
