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 8419 (minimum: 5 - maximum: 343500) Hz was measured.

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
38 ms ... rise ↗ and fall ↘ combined↗ 20.8 ms rise
↘ 17.2 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 96 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (20.6 ms).
   ↔    Response Time 50% Grey to 80% Grey
48 ms ... rise ↗ and fall ↘ combined↗ 26.8 ms rise
↘ 21.2 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. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (32.3 ms).

2018款亚马逊Fire HD 8是一款8英寸的平板电脑，它在性价比方面几乎没有对手。如果您正在寻找一款经济实惠的平板电脑来浏览网页，那么Fire HD 8绝对值得考虑。它的立体声扬声器非常不错，它的续航，整体做工质量和双频Wi-Fi也同样优秀。儿童版则具有非常坚固的保护壳，蓝色或粉红色颜色可选，以及适合儿童的内容。

“2018款Fire HD 8与其前身之间的差异几乎可以忽略不计。尽管如此，他们仍然非常受欢迎，并且考虑到相同的售价，新型号比2017款Fire HD 8更具有吸引力。”

在与可选的显示模式扩展坞配对后，这台平板电脑以极低的价格提供了与亚马逊Echo Show相同的功能。在撰写本文时，第二代Echo Show售价超过200美元，而Fire HD 8 32 GB型号和Show Mode Dock捆绑包的售价仅为140美元。

尽管如此，HD 8还是有些缺点，例如慢得出奇的联发科MT8163四核SoC以及亮度极低的低分辨率（1280x800）显示屏。这款平板电脑还缺少GPS芯片，相机只能说能用，基于Android 7的Fire OS操作系统显然只适用于亚马逊的服务。Google的Play商店可以后续安装，但会使您的保修失效，这点需要注意。
