Abstract: The present disclosure provides a touch display panel including an array substrate, a color filter substrate and a plurality of photo spacers. The array substrate includes pixel units, a drive circuit, touch leads, and a common electrode layer. The common electrode layer is divided into columns of self-capacitive electrodes. Each touch lead is disposed parallel to and connected with one of the columns through at least two first via holes. An interval between adjacent first via holes is greater than or equal to twice the side length of one pixel unit. The first via holes connected with one touch lead are aligned staggered to those connected with an adjacent touch lead and none of the photo spacers overlap the first via holes in the direction perpendicular to the array substrate.

Abstract: An array substrate, a display panel and a display device are provided. The array substrate includes a display area and a non-display area surrounding the display area. A first power signal line, a ground potential line and at least one pressure sensor are disposed in the non-display area. The pressure sensor includes a first power signal input terminal and a second power signal input terminal. The first power signal input terminal is electrically connected to the first power signal line. The second power signal input terminal is electrically connected to the ground potential line. The first power signal input terminal and/or the second power signal input terminal is electrically connected to an electro-static discharge unit.

Abstract: Disclosed are a display panel and a display device. The display panel comprises a first substrate comprising a display region and a non-display region; a second substrate opposite to the first substrate; and a pressure sensor located on one side of the first substrate adjacent to the second substrate and located within the non-display region. The first and second substrates are adhered via a sealant, an orthogonal projection of the sealant on the first substrate is located within the non-display region of the first substrate, a distance from a midline of the sealant to a common boundary between the display region and the non-display region is larger than a distance from a geometric center of the pressure sensor to the common boundary between the display region and the non-display region. The midline of the sealant is a perpendicular bisector of a common perpendicular of the two edges of the sealant.
