Title:
PRESSURE-SENSING DETECTION DEVICE, AND PRESSURE-SENSING PEN
Document Type and Number:
WIPO Patent Application WO/2018/036066
Kind Code:
A1
Abstract:
A pressure-sensing detection device, and a pressure-sensing pen. The device comprises a detection panel (11); an elastic conducting member (10); a power supply (13); and a micro-controller (12). The detection panel (11) has a first detection resistor (110), a voltage dividing resistor and a power supply connection point (111) provided therein. The first detection resistor (110) has one end connected to one pole of the power supply (13) via the voltage dividing resistor, and another end arranged separately from the power supply connection point (111). The micro-controller (12) is connected to one end of the first detection resistor (110) to detect a voltage value. The power supply connection point (111) is connected to the other pole of the power supply (13). The elastic conducting member (10) has one end connected to a driving element (14) and another end separated from the detection panel (11); when a force is exerted on the driving element (14), the other end of the elastic conducting member (10) contacts the detection panel (11), such that the first detection resistor (110) and the power supply connection point (111) are connected to form a loop, and deformation of the elastic conducting member (10) caused by the exerted force changes a resistance between one end of the first detection resistor (110) and the power supply connection point (111). The device of the present invention enables low power consumption when the pressure-sensing detection device is in a standby state, and can reduce manufacturing costs.
