I have a battery powered project that uses a character LCD. How can I reduce the power consumption?
There are a few ways to do this.
1. If there is a backlight, have a timer turn it off after a few seconds. The backlight will draw up to 10X the power of the LCD alone.
2. If the backlight is on all the time, switch to transmissive<https://focuslcds.com/journals/transfle ... cd-module/> and reduce the backlight brightness.
3. Change from a COB (Chip on Board) to COG (Chip on Glass) design.
