The company Huawei enable DC Dimming in the two phones Huawei P30 and Huawei P30 Pro via the software update is currently being released in China. This means that the flagship phones latest buy Huawei decided to join a number of phones growing with screens OLED that creates for PWM for DC Dimming.
What is the difference? In short, the PUC PWM turn pixels on and off quickly to reduce the brightness, hence the name ” modified pulse-width | Pulse Width Modulation “. This leads to the occurrence of the flicker level, which makes some people sensitive suffer from headaches. At the other extreme, says the advantage of DC Dimming by reducing the current sent to each pixel, which reduces the brightness with the Keep it running without a flicker. However, it’s not that simple, because the color emitted from the OLEDs tends to shift at currents low which means that manufacturers need to compensate for this otherwise the color accuracy in the screen will be affected.
According to the changes, it is possible to activate DC Dimming through the option in the settings. This update which has a volume of 400 MB almost also to improve the sensor fingerprint built-in screen, as well as improve the performance and stability of the operating system in both phones. Before concluding, We would like to point out that there is currently no information about whether it will bring the feature to the DC Dimming to phones Huawei previous flagship or not.
