Abstract: An image capturing apparatus including a sensor, an organic light emitting diode (OLED) display panel, and a collimator is provided. The OLED display panel is disposed on an image capturing side of the sensor. The collimator is disposed between the OLED display panel and the sensor. The collimator includes a plurality of collimating devices overlapped with each other. Each of the collimating devices includes a transparent substrate and a light absorbing layer disposed on the transparent substrate. The light absorbing layer includes a plurality of light passing openings, and the light passing openings expose sensing areas of the sensor.
