    Abstract: A light emitting display device and a driving method thereof are provided, in which a luminance difference occurring in a boundary between a fingerprint scanning area and a non-fingerprint scanning area is not perceived by a user. The light emitting display device can include a display panel including a display area where a plurality of pixels is provided to display an image. The display area can include a first area, a second area, and a boundary area disposed between the first area and the second area. In a case where the display panel displays a predetermined image pattern, each of pixels in the first area can emit a first light having a first luminance, each of pixels in the second area can emit a second light having a second luminance lower than the first luminance or cannot emit any light, and the luminance of pixels in the boundary area can be progressively reduced from the first area to the second area.

    Abstract: A display panel and a method for fabricating the same are discussed. The display panel can include a first area in which pixels are disposed, and a second area in which pixels having lower pixels per inch (PPI) than the first area are disposed and a plurality of light-transmitting portions are disposed. The light-transmitting portions include circular or elliptical light-transmitting portions arranged in a zigzag pattern along a second direction crossing a first direction in the second area. Each of the pixel groups in the second area includes a second electrode, and the second electrode is removed from the light-transmitting area to expose light-transmitting portions.

    Abstract: A display panel can include a first area including a first plurality of subpixels, a second area including a second plurality of subpixels, and at least one light-transmitting portion between adjacent subpixels among the second plurality of subpixels. Also, a first subpixel in the first area includes a first light emitting layer, a first thin film transistor including a first channel area, and a first conductive member disposed under and overlapping with the first channel area of the first thin film transistor, and a second subpixel in the second area includes a second light emitting layer, a second thin film transistor including a second channel area, and a second conductive member disposed under and overlapping with the second channel area of the second thin film transistor. The first conductive member in the first subpixel in the first area is on a higher layer than the second conductive member.
