Claim 20:
21. A mobile terminal comprising:
a display panel that includes a plurality of first unit pixel areas in which N subpixels (N is a positive integer greater than or equal to 3) for displaying data are disposed in a display area of the display panel, and a plurality of second unit pixel areas in which N−1 subpixels for displaying data and one sensor pixel for fingerprint sensing are disposed in a sensing area of the display panel;
a display panel driver configured to write the data to the N subpixels and N−1 subpixels;
a fingerprint recognition processor configured to amplify an output signal of sensor pixels of the plurality of second unit pixel areas, convert the amplified output signal into digital data, and output fingerprint pattern data; and
a host system configured to supply data of an input image to the display panel driver, receive the fingerprint pattern data from the fingerprint recognition processor, and process fingerprint authentication,
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, and
wherein each of the plurality of first unit pixel areas is a pixel area in a parallelogram or 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 sensing area are configured to display an image associated with the sensing area, the displayed image guiding a finger of a user to the 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.
