According to the TPS65185 datasheet this should be the max. ratings to drive the pixels:
– TPS651851 LDO1: 15 V, 200 mA at
VIN ≥ 3.6 V (VPOS)
– TPS651851 LDO2: –15 V, 200 mA at
VIN ≥ 3.6 V (VNEG)
I've tested this 16-bit panel with dragon and 16 grayscale's demo:
ED103TC2.pdf
Also upgraded R24 to get a higher VGH positive power (From 22V to 28V)
But still I could not see more than a few lines drawn. And mysteriously the high voltages go to 0 when the display is connected. Quite strange but that's why I'm writing this here, would like to know if this display is over the power specs, or it's another issue. Hints? Ideas?
