I have built an internet radio using the TTGO T_Display module. All working fine but I can't find the best way to shutoff/sleep the Display. I don't want to put the processor to sleep just find a way to use minimum power by blanking the display. I am currently setting the background to black, but in a dark room it's actually a dark gray and still using power. Any suggestions? TIA
It's usually the backlight that is the big power drain, so first of all investigate how you might turn that off. Often there is a display library function that will do it, if it's supported by the display. I don't know the board and you didn't link to it. What display technology does it use?
Much thanks for making me aware of the backlight power use. I have since found many references to solving my problem!
