A display device can include a display panel having an active area including a plurality of subpixels; at least one hole area surrounded by the active area; a boundary area between the at least one hole area and the active area; a first gate line on the active area and the boundary area to supply a scan signal to a first group of subpixels; a second gate line on the active area and the boundary area to supply an emission signal to the first group of subpixels. Also, the display device can include a first data line disposed on the active area and the boundary area to supply a first data voltage to a second group of subpixels; and a second data line disposed on the active area and the boundary area to supply a second data voltage to a third group of subpixels.

Display device

Provided is a display device. The display device includes a base layer including an active area partitioned to display images and an inactive area adjacent to the active area, an opening located in a part of the active area and passing through the base layer and functional layers thereabove, and a cut structure located in the vicinity of the opening and provided to cut the connection of an organic light emitting layer between the opening and a light emitting unit. A camera may be provided in a position corresponding to the opening.

A display apparatus comprises a substrate including a display area and a non-display area adjacent to the display area, a plurality of pixels disposed in the display area, a gate driver disposed on both sides of the display area in the non-display area, the gate driver comprising a plurality of stages including a first stage and a second stage, and a plurality of gate lines extending from the gate driver to the display area, wherein the plurality of gate lines include a first gate line including a linear portion and coupled to the first stage, and a second gate line including a linear portion and a curved portion and coupled to the second stage, and wherein a size of the second stage may be larger than a size of the first stage.

A display device can include a display panel having an active area including a plurality of subpixels, at least one hole area surrounded by the active area, a boundary area disposed between the at least one hole area and the active area, a first gate line on the active area and the boundary area, and supplying a scan signal to a first group subpixels, a second gate line disposed on the active area and the boundary area and supplying a EM signal to the first group subpixels, a first data line disposed on the active area and the boundary area and supplying a data voltage to a second group of subpixels excluding a green subpixel, and a second data line disposed on the active area and the boundary area and supplying the data voltage to a third group subpixels including a green subpixel.

A display apparatus can include an Nscan driving stage among a plurality of scan driving stages, which outputs an Nscan signal to an Npixel and an N+1pixel among the plurality of pixels, in accordance with a scan start signal and a plurality of gate clock signals. Further, an Nreset driving stage among the plurality of reset driving stages outputs an Nreset signal to the Npixel in accordance with a reset start signal and the plurality of gate clock signals. The Nscan driving stage and the Nreset driving stage can be symmetrical with respect to a plurality of gate clock signals lines to which a plurality of gate clock signals is applied, and an anode electrode of the light emitting diode included in the Npixel can be initialized in accordance with the Nreset signal.

Display apparatus

A display apparatus can include an Nscan driving stage among a plurality of scan driving stages, which outputs an Nscan signal to an Npixel and an N+1pixel among the plurality of pixels. Further, an N+1scan driving stage among the plurality of scan driving stages is configured to output an N+1scan signal to the N+1pixel among the plurality of pixels, and a Kreset driving stage among the plurality of reset driving stages is configured to output a Kreset signal to the Npixel and the N+1pixel. An anode electrode of a light emitting diode in each of the Npixel and the N+1pixel is initialized in accordance with the Kreset signal.

Provided is a display device having a structure in which a hole area in which camera sensors or the like are disposed is included in an active area of a display panel. Data lines among a plurality of data lines bypassing the hole area are disposed on different layers to prevent an increase in the load of data lines, through which green subpixels are driven. Degradations in the luminance of subpixels disposed around the hole area and driven through the data lines bypassing the hole area are prevented. The uniformity of luminance around the hole area is improved.
