MUMBAI, India, Sept. 5 -- Intellectual Property India has published a patent application (202047053740 A) filed by Shenzhen Goodix Technology Co. Ltd., Shenzhen, China, on Dec. 10, 2020, for 'capacitance detection apparatus and electronic device.'
Inventor(s) include Yang, Ming; Cheng, Shuqing; Chen, Dansheng; and Guo, Zicheng.
The application for the patent was published on Sept. 5, under issue no. 36/2025.
According to the abstract released by the Intellectual Property India: "A capacitance detection apparatus (10) and an electronic device. The capacitance detection apparatus (10) comprises: a sensing module (11), a connection circuit (12) and a differential detection circuit (13) for detecting a capacitance change of the sensing module (11). The sensing module (11) comprises a base material (111), and a first sensing layer (112) and a second sensing layer (113) which are respectively located on two sides of the base material (111), a first sensing unit (1121) on the first sensing layer (112) being opposite a second sensing unit (1131) on the second sensing layer (113), and the first sensing unit (1121) covering the second sensing unit (1131). The first sensing unit (1121) and the second sensing unit (1131) are electrically connected to the differential detection circuit (13) respectively by means of the connection circuit (12); and when a detected object approaches the capacitance detection apparatus (10), the capacitance of the first sensing unit (1121) is affected by the temperature and the detected object, and the capacitance of the second sensing unit (1131) is only affected by the temperature. By means of the capacitances of the first sensing unit (1121) and the second sensing unit (1131), the effect of the temperature can be eliminated, so as to determine a capacitance change caused by the detected object, thereby improving the accuracy of detection of the capacitance detection apparatus (10)."
The patent application was internationally filed on Sept. 27, 2019, under International application No.PCT/CN2019/108636.
