Abstract
An integrated filter optical package including an ambient light sensor that incorporates an infrared (IR) filter in an integrated circuit (IC) stacked-die configuration is provided. The integrated filter optical package incorporates an infrared (IR) coated glass layer to filter out or block IR light while allowing visible (ambient) light to pass through to a light sensitive die having a light sensor. The ambient light sensor detects an amount of visible light that passes through the IR coated glass layer and adjusts a brightness or intensity of a display screen on an electronic device accordingly so that the display screen is readable.
