TIDA-00373
Backlight and Smart Lighting Control by Ambient Light and Proximity Sensor Reference Design
TIDA-00373
Overview
This system conserves power and extends backlight life by dynamically adjusting the backlight brightness relative to the environment's ambient light. A capacitive proximity sensor wakes up the system when a user is close to save even more power.
