Embodiment Construction

[0039] In the prior art, when a metal material or a panel containing metal components is used in the touch operation structure, it is easy to cause the problem of false triggering.

[0040] This is because in the prior art, the touch operation on the panel is usually determined based on the change of the capacitance of the capacitive sensing element in the touch operation structure. The capacitive sensing element includes a capacitive sensing disk or a capacitive sensor. The structure of the touch operation structure is as follows figure 1 As shown, it includes a circuit board and a panel. The circuit board can be a printed circuit board (PCB, Printed Circuit Board), a flexible circuit board (FPC, Flexible Printed Circuit), etc., and a conductive sponge can be used between the circuit board and the panel. etc. (not shown in the figure), a capacitive sensing element is laid on the circuit board, and there is a touch area corresponding to the capacitive sensing element on the p...

Abstract

The invention discloses a touch identification method and device and a touch operation structure. The touch operation structure comprises a circuit board provided with a first sensing element and a second sensing element in a laying mode, and a metal panel corresponding to the circuit board and covering the first sensing element and the second sensing element. The metal panel is provided with a touch area corresponding to the first sensing element. The method is used for identifying the touch event of the touch operation structure. The method comprises the steps of identifying the trigger event of the first sensing element and the trigger event of the second sensing element, and determining the touch operation in the touch area when the trigger event of the first sensing element occurs but the trigger event of the second sensing element does not occur. The method can be used for obtaining the touch operation in the touch area accurately and prevent spurious triggering. The touch identification method is simple and easy to achieve. The hardware structure of the touch operation structure is simple.

Description

technical field [0001] The invention relates to the technical field of touch sensing, in particular to a touch recognition method and device, and a touch operation structure. Background technique [0002] At present, the types of electronic products on the market are becoming more and more diversified, and the control method of electronic products is what users pay more attention to. Various electronic products, such as smart TVs, washing machines, and refrigerators, can be controlled through mechanical operating structures or touch operating structures in the process of controlling them, for example, through mechanical buttons or touch buttons, etc., but the mechanical There are problems such as poor control experience, unsightly appearance and difficult to clean, etc. The control mode of the touch operation structure is relatively more suitable for user experience requirements. Therefore, the touch operation structure is more and more used in various electronic products. ...
