Problems solved by technology

[0005] However, when the optical sensor module is disposed under a display area (eg, an active area) of a display, since light emitted from a light-emitting structure leaks to a display device (eg, an OLED device), a photoelectric effect caused by the photoelectric effect may occur in the display area. spotting phenomenon
In addition, when the light emitting structure is disposed under the display area in which the transmittance gradually decreases according to the depth, the sensing performance may decrease due to crosstalk caused by diffuse reflection.

Abstract

In embodiments, an electronic device may include a housing, a display panel, and an optical sensor module. The display panel is disposed in an inner space of the housing and is at least partially visible from an outside through the housing, the display including a display area, a first non-display area disposed adjacent to at least a peripheral portion of the display area, and a second non-displayarea disposed adjacent to at least a peripheral portion of the first non-display area. The optical sensor module is disposed in the inner space at least partially overlapping the display panel, and includes a flexible printed circuit board (FPCB), a light emitting structure disposed on the FPCB at least partially overlapping the first non-display area when the display panel is viewed from above,and a light receiving structure disposed on the FPCB at least partially overlapping the display area when the display panel is viewed from above. The display area has a first transmittance, and the first non-display area has a second transmittance greater than the first transmittance.

Description

technical field [0001] The present disclosure relates to an electronic device including an optical sensor module. Background technique [0002] One of the current trends in developing electronic devices to meet customer demands is to make device bodies slim, eg, reduce the thickness of electronic devices. Furthermore, such electronic devices are being developed to increase their stiffness, enhance their design aspects, and differentiate their functional features. [0003] In order to realize a slim electronic device, a plurality of electronic components of the electronic device should be efficiently disposed in an inner space of the electronic device. In addition to this condition, the plurality of electronic components should be properly set to reliably perform their functions. In particular, in the case of electronic components related to large screen displays, such an efficient arrangement within the electronic device may be further required. [0004] Currently, mobile...
