Display Response Times

ℹ
Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
   ↔    Response Time Black to White
26 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 12 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
   ↔    Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 19.2 ms rise
↘ 18.8 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 51 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

我们现在已经测试了联想为当前ThinkPad X1 Carbon提供的所有屏幕版本。与标准的1080p IPS显示屏相比，额外的花销不是太高。由于是亮面屏， WQHD-HDR版本往往更适合多媒体影音娱乐。对于那些主要用于办公室工作以及偶尔在路上使用电脑的人群来说，雾面屏肯定会更好。

对于工作而言，标准的1080p面板不是一个糟糕的选择。是否需要触摸屏取决于您打算如何使用它，但质量基本没有差异（相似的亮度，没有PWM）。可选的雾面WQHD面板给我们留下了良好的印象。亮度不错，显示器具有很大的潜力，并且由于分辨率更高，主观印象略好于1080p显示器。但是续航也因此缩短。

联想ThinkPad X1 Carbon是配备雾面WQHD面板的最佳商务笔记本之一。雾面屏比非常反光的WQHD HDR显示器更适合工作。主观上来说，LG和飞利浦的雾面WQHD面板提供稍好的图像，但另一方面，FHD型号有着更强的续航。
