Description

The TIDA-01364 TI Design conserves power and extends LCD backlight life by dynamically adjusting the LCD backlight brightness relative to the environment's ambient light levels. A capacitive proximity sensor saves power and increases the LCD backlight life by waking up the system from sleep or standby mode when a person approaches.

Features
  • Demonstrates EMI-resistant proximity detection using copper PCB material
  • Excellent human eye spectral response matching with strong IR rejection (<1%)
  • Dynamically adjusts backlight brightness on logarithmic scale based on how the human eye perceives brightness
  • Even LED illumination controlled through white LED driver PWM without calibration
  • Integrated backlight UV filter enables good performance in outdoor applications
