Cross-talk prevention structure of electronic device for measuring distance to external object

Abstract

An electronic device for reducing noise occurring in measuring a distance to an external object is provided. The electronic device includes a cover glass, a rear cover facing the cover glass, a display disposed between the cover glass and the rear cover and having a hole formed in a specified area, a shielding layer disposed between the display and the rear cover and having the hole formed in an area corresponding to the specified area, a sensor module disposed in the hole to measure a distance between the electronic device and an external object, a printed circuit board (PCB) disposed between the shielding layer and the rear cover, and at least one processor disposed on the printed circuit board and operatively connected to the sensor module, wherein the sensor module may include a light emitting part that emits light based on a signal received from the processor, and a receiving part to receive the emitted light after being reflected from the external object and returning back, and a diaphragm structure disposed between the light emitting part and the receiving part and including a first region blocking first reflected light reflected from the shielding layer among the emitted light and a second region blocking second reflected light reflected from the cover glass among the emitted light.
