Abstract
Disclosed is a bio sensing device including a medium layer, a light emitting element and an optical sensor. The light emitting element is configured to emit a light toward a user's skin layer, in which the light passes through the medium layer and has a maximum intensity in a first wavelength. The optical sensor is configured to receive a reflected part of the light from the user's skin layer, in which the reflected part of the light passes through the medium layer, and the medium layer has a first transmittance greater than 60% with respect to the first wavelength.
Claims18
A bio sensing device, comprising:
- a medium layer;
- a light emitting element configured to emit a light toward a user's skin layer, wherein the light passes through the medium layer and has a maximum intensity in a first wavelength;
- an optical sensor configured to receive a reflected part of the light from the user's skin layer, wherein the reflected part of the light passes through the medium layer, and the light emitting element is not overlapped with the optical sensor in a normal direction of the medium layer;
- and
- a first transistor directly connected to the light emitting element, wherein a gate electrode of the first transistor is not overlapped with the light emitting element in the normal direction,
- wherein the medium layer has a first transmittance greater than 60% with respect to the first wavelength.
