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.
