PRESSURE DETECTION DEVICE AND STYLUS
Document Type and Number:
WIPO Patent Application WO/2019/000185
Kind Code:
A1
Abstract:
A pressure detection device, comprising: a detection head (210), a protection apparatus (220) and a pressure sensor (230). The detection head (210) is used for receiving a first pressure; and the protection apparatus (220) is used for outputting a second pressure to the pressure sensor (230) when the detection head (210) receives the first pressure, wherein, when the first pressure is smaller than or equal to a first threshold, the second pressure is equal to the first pressure, and when the first pressure is greater than the first threshold, the second pressure is smaller than the first pressure. The protection apparatus may effectively protect the pressure sensor, so that the service life of the pressure sensor is increased, the repair rate is reduced, and the product competitiveness is increased.
