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 8706 (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
28 ms ... rise ↗ and fall ↘ combined	↗ 15 ms rise
28 ms ... rise ↗ and fall ↘ combined	↘ 13 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. » 68 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (20.9 ms).
↔ Response Time 50% Grey to 80% Grey
42 ms ... rise ↗ and fall ↘ combined	↗ 21 ms rise
42 ms ... rise ↗ and fall ↘ combined	↘ 21 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. » 64 % of all devices are better. This means that the measured response time is worse than the average of all tested devices (32.8 ms).

O CUBOT R11 é um dispositivo de menos de €100 que impressiona com sua carcaça robusta e longa duração da bateria. No entanto, agora há muitos dispositivos com preços semelhantes que oferecem mais potência, melhores câmeras e suporte para LTE. No lado positivo, o CUBOT R11 tem uma bateria substituível, uma relação de aspecto de 2:1 e dimensões compactas, a última das quais beneficiará aqueles com mãos menores.

O CUBOT R11 é um smartphone de baixo custo que tem boa duração de bateria, uma bateria substituível e uma carcaça robusta. No entanto, um SoC mais poderoso teria feito maravilhas.

No geral, o CUBOT R11 é um típico smartphone de nível básico que se sai bem em algumas áreas, mas em outras nem tanto.
