Abstract: A display device can include a display panel including a first area and a second area surrounded by the first area, where each of the first area and the second area includes a plurality of subpixels. The display device can further include a plurality of first driving thin film transistors disposed respectively in the plurality of subpixels positioned in the first area, and a plurality of second driving thin film transistors disposed respectively in the plurality of subpixels positioned in the second area. The second area can include a transparent area. For at least one of the plurality of the second driving thin film transistors, a length of the channel region of the second driving thin film transistor can be shorter than a length of the channel region of the first driving thin film transistor.

Abstract: A display device in one example includes a display panel comprising a first area including at least one first subpixel and a second area including at least one second subpixel, a first driving thin film transistor disposed in the at least one first subpixel, and a second driving thin film transistor disposed in the at least one second subpixel. The number of the at least one first subpixel disposed per a unit area in the first area is greater than the number of the at least one second subpixel disposed per a unit area in the second area. Further, the width of a channel region of the second driving thin film transistor is greater than the width of a channel region of the first driving thin film transistor.

Abstract: Embodiments of the disclosure are related to a display device, in a structure where an optical sensor is disposed on an opposite side of a side displaying an image and overlapping an active area of a display panel, as increasing a transmittance by implementing an area overlapping to the optical sensor as a low resolution area, a sensing function by the optical sensor located in the active area could be implemented. Furthermore, by implementing a number of a gate electrode or a width of a channel region or the like of a driving transistor disposed in the low resolution area to be different from those of a driving transistor disposed in a high resolution area, compensating a luminance of the low resolution area and preventing a deviation of a luminance between the low resolution area and the high resolution area can be achieved.
