Claim 0:
1. A display panel comprising:
a plurality of first unit pixel areas in a display area of the display panel; and
a plurality of second unit pixel areas in a first sensing area of the display panel,
wherein each of the plurality of first unit pixel areas includes N subpixels displaying data where N is a positive integer equal to or greater than 3,
wherein each of the plurality of second unit pixel areas includes N−1 subpixels displaying data and the plurality of second unit pixel areas are configured to sense a fingerprint in the first sensing area,
wherein the plurality of first unit pixel areas are arranged at equal intervals in a first direction and a second direction crossing the first direction in a plan view of the display panel,
wherein the plurality of second unit pixel areas are arranged at equal intervals in the first direction and the second direction in the plan view of the display panel,
wherein each of the plurality of first unit pixel areas and each of the plurality of second unit pixel areas have a same size,
wherein each of the plurality of first unit pixel areas is a pixel area in a parallelogram shape or a rhombus shape that is different from the parallelogram shape from a perspective of the plan view of the display panel, and the plurality of second unit pixel areas includes a second unit pixel area in the parallelogram shape from the same perspective of the plan view of the display panel and another second unit pixel area having the rhombus shape that is different from the parallelogram shape from the same perspective of the plan view of the display panel,
wherein each of the second unit pixel area in the parallelogram shape and the other second unit pixel area in the rhombus shape that is different from the parallelogram shape from the same perspective of the plan view of the display panel includes a sensor pixel and subpixels of three different primary colors such that the subpixels include a single instance of each primary color,
wherein the plurality of second unit pixel areas in the first sensing area are configured to display an image associated with the first sensing area, the displayed image guiding a finger of a user to the first sensing area,
wherein each of the plurality of first unit pixel areas includes subpixels of three different primary colors, where two of the subpixels have one color among the three different primary colors and remaining subpixels in the first unit pixel area include a single instance of each remaining primary color,
wherein each of the plurality of first unit pixel areas includes two green subpixels, and
wherein green subpixels disposed in the plurality of second unit pixel areas are in a same row of subpixels as the sensor pixel and display the data in a display mode, and are driven as a light source in a fingerprint recognition mode.
