校正後的brightness是在26%
所以看起來可以避免閃爍問題?
引自原文:
Out of the box the screen gives a luminance of ~114 cd/m2 at the 20% brightness setting (See our brightness and contrast stability tests) which should prove adequate as a lower level of adjustment for those who still want to avoid the use of PWM for lower brightness levels.

比較起其它TFT有測的螢幕
ASUS PB278Q - Pulse Width Modulation Used
Yes
Cycling Frequency
~240 Hz
Possible Flicker at
100% Brightness No
50% Brightness Yes
10% Brightness Yes

U2713HM - Pulse Width Modulation Used
No
Cycling Frequency
n/a
Possible Flicker at
100% Brightness No
50% Brightness No
0% Brightness No

這代表U2713HM是PWM-free的嗎

看到這個蠻有趣的, 我也拿我的螢幕來試
用手機的相照找看看有沒有因為亮度的改變水波紋能有改善

結果brightness要到100%水波紋才會消失
看起來真糟糕

倒是ipad3怎麼用都拍不出水波紋, 難不成ipad本身是比較PWM-free的性質嗎
