Honor 90 Sequence will launch on Could 29 and it’ll equip with 3840Hz PWM dimming. The function is named zero-risk dimming eye safety. In the meantime, it is going to solely allow with 120Hz show refresh fee. Moreover, the enter reveals that the cellphone has handed the TÜV Rheinland flicker-free certification and reached the zero-risk dimming stage.
That is the very best PWM dimming quantity on any smartphone. As in comparison with this, Honor Magic 5 sequence had display screen options of as much as 2160Hz high-frequency PWM dimming, dynamic dimming, and circadian evening show for eyes consolation.
Subsequently, 3840Hz PWM dimming on Honor’s upcoming telephones will probably be an thrilling tech to witness.
What’s PWM (Pulse Width Modulation) Dimming?
LEDs may be dimmed utilizing two strategies: analog and pulse-width modulation (PWM). Analog dimming modifies LED gentle output by adjusting the DC present within the string, whereas PWM dimming modifies the typical present within the string by various the responsibility cycle of a relentless present within the string.
Alternatively, we will say PWM is a way for controlling the brightness of a show panel by various the width of the sunshine pulse. Merely put, you management how lengthy the display screen stays on or off. Decreasing the brightness causes the display screen to be off for longer than it’s on, which is perceived as decrease brightness.
