What’s the functional difference between putting the display to sleep and setting the display backlight to 0? I am using some code in the screen to collect data from the serial port, and the data collection stops when I put the display to sleep. I would prefer to just set the backlight to 0 and then allow the data to be collected. Then when a screen is touched, the backlight gets set back to 100.
Any thoughts on this? Will I hurt the display by keeping it running continuously?
