  • Patent number: 10627946
    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.

  • Patent number: 10528173
    Abstract: Disclosed are an array substrate, a display panel, a display device and a method for manufacturing an array substrate. The array substrate includes a base substrate, comprising a display region and a non-display region surrounding the display region, and the display region of the base substrate is provided with a plurality of pixel units, with each of the pixel units comprising a thin-film transistor; and at least one pressure sensor, which is disposed on the non-display region of the base substrate, and the pressure sensor is disposed in the same layer and made of same materials with an active layer of the thin-film transistor, the active layer includes a channel region and a heavily doped region, and a square resistance of the pressure sensor is larger than that of the active layer.

  • Patent number: 10168816
    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.
