Dear Everybody
I cannot manage to provide around 120 VAC 400 Hz @0.5 mA supposed to be required for electroluminiscent backlight of a)Lampex 16x1 b)Techstar 16x2 LCDs.No datasheet worth its name.Can you help me lighting my LCD EL backlights,cost effectively?
Incidentally I have no problem with LED backlights,
contrast control and other related software issues
except that this EL backlight which eventually has to be soft controlled.I have Googled enough and I think
the best was by dual opamps; one giving triangular
outputs and the other comparing this with control data
to output a PWM at 400Hz.Any actual experience?
