Abstract: The present disclosure provides a display substrate, display panel, and display device. The display substrate includes: a base substrate having a display area and a periphery area surrounding the display area; a plurality of force sensors disposed in the periphery area; and a substrate layer layered upon the base substrate and disposed under a film layer where the plurality of force sensors are located and including a plurality of strip-shaped convex structures; wherein a portion of each of the plurality of force sensors corresponding to each of the plurality of strip-shaped convex structures is convex, and another portion of each of the plurality of force sensors corresponding to a gap between adjacent two of the plurality of strip-shaped convex structures is concave. The present disclosure achieves that abnormal display will not appear on display panel at display area edge or position corresponding to force sensor, thereby improving display effect.

Abstract: An array substrate and a touch control display panel are provided. The array substrate comprises a display area and a non-display area surrounding the display area; a plurality of touch control electrodes comprising a plurality of first touch control electrodes and a plurality of second touch control electrodes; and a plurality of touch control signal lines. A first touch control electrode is disposed only in the display area. A second touch control electrode includes a first portion disposed in the display area and a second portion disposed in the non-display area. A ratio m between an area of the first portion of the second touch control electrode and an area of the first touch control electrode is configured to be approximately 0.067≦m≦0.65. A touch control electrode is electrically connected to at least one of the plurality of touch control signal lines.
