Abstract

A pressure detection structure and a touch device are disclosed. The structure is mounted on a middle frame of the touch device and includes a cover, a display device and a pressure sensor. The display device is arranged below the cover, and includes a display module. The pressure sensor is arranged in the display device; any electrically conductive member in the display device or the middle frame which is electrically conductive is used as a reference electrode; and a variable gap is present between the pressure sensor and the reference electrode, and the pressure sensor outputs a pressure signal according to variation of capacitance between a sensing electrode thereof and the reference electrode. According to the present application, pressure detection may be carried out accurately, and thus reliability of products is enhanced.
