PWM dimming is projection screen engineering science that ’s being introduced to more and more smartphones , but what is it and is it worth splashing out on a smartphone that has it ?
While the idea of a smartphone screen that facilitate reduce eye fatigue and irritation may sound a lilliputian unfixed , PWM blur tech object to do precisely that .
Here ’s everything you need to make love about PWM dimming , from an explanation of the tech to why it ’s important on smartphones and which telephone set currently have the fastest PWM dimming rate on the market .
What is PWM Dimming?
PWM Dimming is short for Pulse Wave Modulation Dimming , and it ’s basically a show technology that allows a display to turn on and off at a very eminent frequency to simulate brightness , with the gap between the on body politic dictate how undimmed or dim the screen is .
This flickering is think to be imperceptible to the naked eye , and while that is indeed the case for high PWM dimming screens , flickering can be an issue at down in the mouth brightnesses if it ’s not quite fast enough . In fact , some user report develop eye strain or even headache when using smartphone screen at a lower brightness level with a low PWM dimming pace .
Therefore , PWM Dimming is a presentation technical school that ’s framed as being much fitter for the drug user ’s center , especially as sieve brightness stage drop with exercise in darker environments . As such , company like OnePlus , Honor and Xiaomi are all implementing impressively gamey PWM blur rate technical school into their latest smartphones .
Why is PWM Dimming important on a smartphone?
PWM dimming is particularly significant on a smartphone because it ’s the gimmick that most of us tend to use most of the time , particularly when it comes to late evenings when roll down for bed when screen video display are of specially grim luminousness . How many of us are shamefaced of a last - minute TikTok roll or Instagram binge before getting some shut - eye ? Exactly .
PWM Dimming essentially allows for an eye strain - spare scrolling experience in those murkily illuminate ocndiitons , with brands like Honor going a stride further by claiming that the tech can also improve the quality of your sleep .
Away from the anti - flicker focus of the tech , PWM Dimming also permit the screen to preserve the colours and efficiency of the show without changing the voltage or current , deliver good power ingestion of the display .
fuse , it essentially means you ’re getting a flicker - free display that ’s both vivacious and battery - effective .
Which smartphones offer high PWM Dimming technology?
While not all PWM - dimming - equipped smartphones are equal – the PWM dim refresh rate vary among both manufacturer and specific role model of smartphone – the gamey refresh pace available on PWM dim screen door should all make some difference .
That pronounce , here ’s a lean of some of the most popular smartphones with PWM Dimming and , where possible , the colligate refresh rate :
