JTL Thanks!
Btw, I noticed in the pictures that the R, G and B channels seem out of phase in the PWM. Could that mean it has one of the backlights where separate R, G and B LEDs were used? Or maybe just a colour temperature change at different points during the on-off cycle of CCFL?
It's still not that great for long term use, but it feels far less harsh than the scanning between black and white on the OLED phones.
