    if you have an oled display, then if a video game is brighter it costs more energy because the LEDs turn on more.

    if have an lcd display, there’s a backlight that always has the same brightness and crystals blocking the light, which makes the image. meaning a brighter scene doesn’t take more power, since the backlight doesn’t use more energy.

      On an LCD display, the backlight is always on but the crystals need power to align and let the backlight through.

      A full white screen would in theory use more electricity than a full black screen. How much more, I don’t actually know but I would like to know more info in it.
