Abstract: The present disclosure provides display panel and display device. By adjusting positions of the input signal line and the output signal line of the force sensor, the problem that output signal of the force sensor in the existing display panel is interfered by signal transmitted on the peripheral circuit wirings. Non-display area of the display panel is provided with force sensor and driving circuit; the distance between an orthographic projection of the first output signal line of the force sensor on the display panel and an orthographic projection of the driving circuit input line on the display panel is at least 30 μm; and the distance between an orthographic projection of the second output signal line of the force sensor on the display panel and the orthographic projection of the driving circuit input line on the display panel is at least 30 μm.

Abstract: A touch screen is provided. The touch screen includes a first strain sensor located in a first region, a second strain sensor located in a second region, a first power supply and a first voltage detector. The first region is surrounded by the second region, the first power supply is configured to provide an operating voltage to the first strain sensor and the second strain sensor. The first voltage detector is configured to detect a voltage of a common terminal of the first strain sensor and the second strain sensor, and one terminal of the first voltage detector is connected to a first preset voltage, and the other terminal of the first voltage detector is electrically connected to the common terminal of the first strain sensor and the second strain sensor.
