  • Publication number: 20180173347
    Abstract: A display panel and a display device are disclosed. The display panel includes at least one notch which includes a protrusion structure. A non-display region includes at least one first non-display region arranged along edges of the protrusion structure. At least one first pressure sensor is provided in the first non-display region. An included angle between a first strain detection direction of the first pressure sensor and a first edge of the display panel is greater than or equal to 65 degrees and less than or equal to 115 degrees. An included angle between a second strain detection direction and the first edge of the display panel is greater than or equal to ?25 degrees and less than or equal to 0 degree. A control chip is provided in the non-display region, and the first edge is an edge of the display panel close to the control chip.

  • Publication number: 20170131579
    Abstract: A liquid crystal display panel and a liquid crystal display device are provided. The liquid crystal display panel comprises a first substrate, a second substrate, a liquid crystal layer sandwiched between the first and second substrate, and an auxiliary electrode. The first substrate includes a plurality of gate electrode lines and a plurality of data lines intersected to define a plurality of pixel units. Each pixel unit corresponds to a pixel electrode and a common electrode. In each region corresponding to one pixel unit, the pixel electrode and the common electrode are configured to form an electric field that drives the liquid crystal layer. A vertical projection of the auxiliary electrode on the first substrate covers an area where the electric field is formed by the pixel electrode and the common electrode, and a thickness of the liquid crystal layer is less than or equal to 3.2 ?m.
