Abstract: A touch-control display panel, driving method, and a touch-control display device are provided. The touch-control display panel includes: a display area including a plurality of pixels; a non-display area; a first substrate; and a second substrate opposing the first substrate. A portion of the first substrate in the first region includes a pixel electrode layer and a first electrode layer. The first electrode layer is located on a side of the pixel electrode layer away from the second substrate and includes a plurality of first electrodes. The pixel electrode layer includes a plurality of pixel electrodes. A touch-control electrode layer is located on a side of the second substrate toward the first substrate and includes a plurality of touch-control electrodes. Along a direction perpendicular to the touch-control display panel, each touch-control electrode of the plurality of the touch-control electrode overlaps with and connects with one or more first electrode of the plurality of the first electrodes.

Abstract: A display panel and a display device are provided. A first optical component area has a first width along a first direction greater than a second width along a second direction, and a display area includes a first display area and a second display area located at two sides of the first optical component area along the second direction. The display panel includes first signal lines, which include first-type signal lines and second-type signal lines and each include a first portion arranged in the first display area and a second portion arranged in the second display area. A first bypass portion connecting the first portion and the second portion of the first-type signal line is arranged in the display area. A second bypass portion connecting the first portion and the second portion of the second-type signal line is arranged in the first frame area.
