There are a few of interesting comments in this thread: https://www.reddit.com/r/apple/comments/7uv6m3/iphone_x_uses_pulse_width_modulation_which_is_a/?st=JM3ZG0DU&sh=d12d2cf9 https://www.reddit.com/r/apple/comments/7uv6m3/iphone_x_uses... In summary they are saying that low frequency (240Hz) PWM is used for amoled because it decreases sub-pixel wear, it prevents color distortion, it's cheaper. So it looks like this won't change. I got an amoled phone and was surprised that the experience was worse than LCD (for me - it seems to depend a lot on the individual). Didn't even know that PWM was used until I started googling eystrain and amoled. Anyway, I sent the phone back.
