Abstract

The present disclosure provides a touch sensing device and electronic equipment with improved touch sensing discrimination, the touch sensing device including: a first touch sensing unit including a first sensing electrode and a first sensing inductor electrically connected to each other, wherein a capacitance of the first touch sensing unit varies according to a parasitic capacitance formed between the first sensing electrode and an external object based on the contact of the external object; a first force sensing unit including a first sensing coil spaced apart from an inner side surface of the frame, wherein an inductance of the first force sensing unit changes according to a change in a distance between the first sensing coil and the frame based on a pressing touch; and a circuit unit configured to detect whether a touch of the external object is input based on a change in the capacitance of the first touch sensing unit and a change in the inductance of the first force sensing unit.

Description

[0001] This application claims Nos. 10-2020-0066813, 10-2020-0110345, and 10 filed with the Korean Intellectual Property Office on June 3, 2020, August 31, 2020, and September 10, 2020, respectively. - The benefit of priority of Korean Patent Application No. 2020-0116281, the entire disclosure of which is hereby incorporated by reference for all purposes. technical field [0002] The present disclosure relates to touch sensing devices and electronic devices with improved touch sensing discrimination. Background technique [0003] In general, it is desirable for wearable devices to be thin and have a simple, clean design. To achieve these properties, existing mechanical switches in wearable devices can be replaced with non-mechanical switches implemented using dust- and water-resistant technologies, enabling the production of wearable devices with seamless casings. [0004] For the purpose of realizing and developing non-mechanical switches, technologies such as touch-on-met...
