TOUCH PRESSURE DETECTION MODULE AND DEVICE
FIG3 is a schematic diagram of a key touch of a pressure sensing component based touch pressure detection module according to an embodiment of the present invention
FIG3 is a schematic diagram of key touch of the pressure sensing component based touch pressure detection module according to an embodiment of the present invention. As shown in FIG3, the pressure sensing component 2 is not directly touched by a finger 5, a cover 3 (for example, a cover plate of a mobile phone) is arranged on the pressure sensing component 2; the cover 3 is attached to the pressure sensing component 2 via an adhesive 4, and the finger 5 applies a pressure on the pressure sensing component 2 by touching the cover 3. When the finger 5 touches the cover 3, a pressure is applied on the cover 3, and the pressure is transferred to the pressure sensing component 2 via the cover 3 and the adhesive 4. In some embodiments, the finger may alternatively directly touch the pressure sensing component 2, which is not limited in the embodiments of the present invention.
