    Is a LCD screen less bad than LED in connection with Flickr and Blue Light?

    IGot a few other questions that are related to this.

    Does blocking blue light reduce flicker?

    Does blue light have more flicker than any other wavelength?

    LED screens use LED backlights, LCD uses fluorescent-type backlights.
    "The most common cause of flicker is fluctuation in the power source of a light. In incandescent lamps, this was the natural fluctuations of the AC grid that was “filtered” only by the heat storage of a filament, resulting in 6-11% flicker. Early magnetic ballasted fluorescent lights had extremely high flicker, 80-100%."
    So you would have to test your screen, there is no "one size fits all" answer.
    This is the app i use to test flicker.
