Problems solved by technology

The capacitance change generated by the edge holding touch 22 will affect the normal operation of the touch panel, such as figure 2 As shown, the processor can not only determine the coordinates (Xn, Yn) of the normal touch point 20 according to the change of the capacitance of the X and Y axes, but also detect the false touch point (Xn, Yn) caused by the edge holding touch 22 -1) and (Xn, Yn+1), thereby causing misoperation of the touch panel 10

Embodiment Construction

[0019] The present invention will be described in further detail below in combination with specific implementation methods and accompanying drawings.

[0020] like image 3 As shown, the touch panel 100 includes a plurality of first-axis electrodes 101 and second-axis electrodes 102 , and the first-axis electrodes 101 and the second-axis electrodes 102 intersect and are insulated from each other. The area available for sensing operation of the touch panel 100, that is, the area provided with the sensing electrodes can be divided into an edge area A and an operation area B, and the edge area A includes a left edge area, a right edge area, an upper edge area and a lower edge area. one or more. For example, it can be set that the corresponding electrodes from left to right in the left edge area are X1, X2 and X3 areas, and the corresponding electrodes from left to right in the right edge area are Xn-2, Xn-1, Xn areas. Similarly The corresponding electrodes from top to bottom of...

Abstract

The invention provides a holding touch detection method of an edge of a touch panel, and the method comprises the following steps of judging whether the state of an edge area is changed or not; deleting a first edge signal if the state of the edge area is not changed; and updating the first edge signal to be a next benchmark signal if the state of the edge area is changed. The invention also provides a holding touch detection device of the edge of the touch panel. Due to the adoption of the detection method and the detection device, the state and data of the edge area can be detected in time and updated dynamically, so that the edge touch signal can be deleted from the touch signal of the touch panel to obtain a normal touch signal, and the influence of the edge holding touch on the normal operation of the touch panel can be reduced.

Description

technical field [0001] The present invention relates to touch panel technology, in particular to a method and device for detecting edge grip touch of a touch panel. Background technique [0002] At present, the technology of directly operating electronic devices by touching objects such as fingers has been widely used in daily work and life. These electronic devices generally use touch panels to sense touch actions and generate corresponding electrical signals for subsequent operations. According to different touch sensing principles, touch panels are mainly divided into resistive, capacitive, optical, electromagnetic, and acoustic wave types. The working principle of the capacitive touch panel is: the user touches the surface of the panel with a conductive object such as a finger or a sensor pen, resulting in a capacitance change at the touched position of the touch panel, and the processor detects the capacitance change to calculate the touch position coordinates to achi...
