The wiki of the pinetime mentiones the LCD driver part number, but nothing about the part number of the actual display. or backlight. It does mention the 3 backlight pins (low mid high), and according to the schematic these are just connected to a 2k2, a 100R and a 30R resistor, this suggests 3 different brightness levels, but you could get even more brightness levels if you were to combine these 3 brightness levels, but it doesn't really look like that was the intention of the original design. Now I am wondering. Can I pull all these 3 pins low without sending too much current to the backlight?
