Abstract: The present disclosure is related to a display panel for interfacing with a plurality of sensors that are attached to a bottom surface of the display panel. The display panel includes a light emitting layer configured to output images, and a protective layer configured to protect the display panel. The light emitting layer includes a display region having a first pixel density, a first transmissive region having a second pixel density that is less than the first pixel density, and a second transmissive region having a third pixel density that is less than the second pixel density. The first transmissive region is configured to interface with a first sensor and the second transmissive region is configured to interface with a second sensor, wherein a function of the first sensor requires less light than a function of the second sensor.

Abstract: The present disclosure relates a display device and a method compensating for deterioration thereof, and a mobile terminal including the display device. The display device includes: a display panel including a first pixel area, a second pixel area, and a third pixel area; a first optical device disposed below the display panel or embedded within the display panel in a predetermined sensing area on the display panel, the first optical device facing at least a portion of the first pixel area and a portion of the second pixel area when the display panel is folded or moved; and a pixel deterioration compensation circuit configured to operate to reduce a luminance difference between the first pixel area and the second pixel area by receiving sensing data from the first optical device in a deterioration sensing mode.
