Sensor including first optical member with reflection property and second optical member with absorption property capable of absorbing light reflected by first optical member and electronic device including the same

Abstract

According to an embodiment, an electronic device, comprises a transparent member, an optical sensor disposed under the transparent member and including a light transmitter configured to emit light of a designated wavelength band and a light receiver configured to obtain light of the designated wavelength band emitted from the light transmitter and reflected by an external object adjacent to the transparent member, a first optical filter disposed between the transparent member and the optical sensor, having a first transmittance for light of the designated wavelength band, and configured to reflect light outside the designated wavelength band, and a second optical filter disposed between the transparent member and the first optical filter, having a second transmittance less than the first transmittance for light of the designated wavelength band, and configured to absorb at least a portion of the light reflected by the first optical filter.
