Problems solved by technology

[0005] However, because different people have different charges and finger sizes, or the same person has different charges in different states (sweating or not), the capacitive coupling changes that may be caused are also different, and a defined state will appear. An error occurred, defining the hover state as a touch state or defining a touch state as a hover state

Abstract

The invention relates to the field of touch control, in particular to a touch and hover sensing device, method and system. The touch and hover sensing device comprises a capacitive touch panel, a pressure sensor and a control unit; the capacitive touch panel and the pressure sensor are connected with the control unit; the capacitive touch panel is used for receiving an input event; the pressure sensor is used for judging a pressure change caused by the input event; and if the pressure sensor has the pressure change, the control unit determines a current state as a touch state. According to thetouch and hover sensing device, method and system provided by the invention, the pressure sensor is added and can sense the pressure change caused by input event detection; if the pressure change iscaused, the current state is determined as the touch state, so that the touch sensing is more accurate; and no matter how many loads a human body bears, the input of a touch event can be accurately sensed, so that the sensing accuracy is greatly improved and the user experience is effectively improved.

Description

technical field [0001] The present invention relates to the field of floating touch, in particular to a touch and hover sensing device, method and system. Background technique [0002] In recent years, with the continuous advancement of image display technology, the touch system has become one of the commonly used displays in the market due to its advantages of direct input of commands through touch, and has been widely used in various in electronic products. [0003] Generally speaking, touch systems can be roughly classified into capacitive touch panels, resistive touch panels, and optical touch panels according to types. Take the capacitive touch panel as an example. The touch panel itself has a parasitic capacitance Cp. When a finger approaches, an additional capacitance Cf will be generated between the capacitive touch panel and the finger. When the capacitance changes, it also means that the charge occurs. The position of the finger on the touch panel can be calculat...
