Abstract

The present invention relates to a touch control device and an edge nonlinear compensation method thereof. The touch control device comprises a touch control panel and a controller, wherein the touch control panel has a sensing layer formed by a plurality of sensing electrodes which are arranged in parallel and at least one sensing wire arranged at an edge of the sensing layer, the sensing wire has a sensing section corresponding to the sensing electrodes of the edge of the sensing layer, the controller is respectively electrically connected with the sensing wire and the sensing electrodes on the sensing layer, different inter-wire compensation sensing quantities are correspondingly set for different positions on the sensing section, for compensating for the sensing quantity measured by the sensing electrodes of the edge of the sensing layer, so as to improve a non-linear phenomena of edge point reporting offset of the touch control panel.

Description

technical field [0001] The present invention relates to a touch device and a compensation method thereof, in particular to a nonlinear compensation method and a touch device for solving edge reporting offset of a touch panel. Background technique [0002] At present, the touch interface has become the mainstream operation interface of devices such as mobile phones and tablet computers, and users mainly select and execute function items on the touch panel by touching them, or move objects by dragging them. According to the principle of touch control, the touch panel detects the user's touch position and reports its coordinates (hereinafter referred to as reporting points), so as to execute the corresponding function items on the coordinates. However, the touch panel is prone to non-linear phenomena in certain areas, which may cause incorrect point reporting. [0003] like Image 6 Shown is a mobile phone 70 using a touch interface. The touch panel of the mobile phone 70 has ...
