[閒聊] S20 FE 亮度超過30%自動進入DC調光模式?

看到notebookcheck這樣講 嚇了一跳 真有這種技術? https://bit.ly/2IWEEnn PWM flickering only occurs at display brightness levels of 30% and less. Above this level, automatic DC dimming starts The display backlight flickers at 227.3 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 30 % and below. There should be no flickering or PWM above this brightness setting. 如果有鄉民覺得notebookcheck不可信 可以去借S20 FE來測 一個月前板上看到一種說法: iPhone12亮度25%以上採DC調光 #1Va-k6qc (MobileComm) https://www.ptt.cc/bbs/MobileComm/M.1603529606.A.D26.html 照notebookcheck的測試 上述說法並不正確 iphone 12只有在最大亮度停止閃爍 https://bit.ly/3nKXD3t Because OLEDs don't have background lighting that you could dimm, the entire screen has to be turned on and off all the time to achieve a lower brightness. This causes flickering, which we measured at 226.2 Hz on the iPhone 12. It only stops at maximum brightness. 相信某些對PWM著迷的鄉民會努力去驗證notebookcheck的說法 據oneplus創辦人的說法 什麼類DC調光 那只是廠商的噱頭啦 別被騙了 -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 140.112.25.121 (臺灣) ※ 文章網址: https://www.ptt.cc/bbs/MobileComm/M.1606131934.A.1A9.html
