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 | ||
|---|---|---|
| 27 ms ... rise ↗ and fall ↘ combined | ↗ 13 ms rise |  |
| ↘ 14 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. » 64 % 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 | ||
| 43 ms ... rise ↗ and fall ↘ combined | ↗ 23 ms rise |  |
| ↘ 20 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. » 68 % 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 8734 (minimum: 5 - maximum: 343500) Hz was measured. | |||

新款Yoga Book的电子墨水屏非常独特。它最大的优点是它的多功能性。它非常小巧轻便，可用作笔记本电脑，平板电脑或电子阅读器。但当然，这种灵活性也需要一些妥协。
例如，键盘不适合频繁打字机，也没有背光。对于传统笔记本用户来说，接口很少是件麻烦事。如果您只需要一个电子阅读器，您可能会需要更轻的设备。
“联想笔记本部门针对的客户群体是那些希望将所有功能（手触，笔触，电子阅读器等）组合到一个设备中的人。正在寻找普通笔记本电脑的用户可能不会对其感到满意。”
尽管如此，令人惊讶的是联想已经成功地将所有这些功能组合到这样一个轻薄本中。它的设计和酷炫的功能将Book C930变成了一个真正吸引眼球的笔记本电脑。由于我们的评估系统中没有单独的电子墨水显示类别，因此我们手动为结果添加了两个百分点。
一些用户可能认为价格是另一个劣势——起价1050美元（约7000元人民币），该设备的定价约为其前身的两倍。除了许多改进之外，一些功能也已消失。没有了使用纸张图像数字化的可能性，更好的主摄像头也不见了，更不幸的是，续航时间明显短于其前代产品。不过性能上倒是有了显着提高，显示效果也更好。最重要的是：目前该设备没有真正的竞争对手。
