Title: TOUCH PRESSURE DETECTION DEVICE AND METHOD
Abstract:
Disclosed are a touch pressure detection device and method. The device comprises a fingerprint sensor module and a touch pressure calculation module. The fingerprint sensor module comprises multiple sensing units. The fingerprint sensor module is used for collecting, by means of the multiple sensing units, texture information data of a body part touching the fingerprint sensor module. The touch pressure calculation module is used for calculating a touch pressure of the body part according to the collected texture information data. In this way, the touch pressure is detected by means of a fingerprint sensor in the prior art. By using the touch pressure detection solution in the present invention, no additional physical hardware or structure or assembly design is needed, additional cost expense is basically avoided, and under the condition that fingerprint recognition of mobile terminals becomes more and more popular, the application and popularization of the touch pressure detection device and method in the present invention are facilitated. Compared with a touch pressure detection method in the prior art, the touch pressure detection device has high detection sensitivity, a simple implementation structure, low cost and a small size.
