Abstract

The invention provides a capacitance value self-calibration device and method as well as a touch display device. The capacitance value self-calibration device comprises a capacitance value detection unit and a capacitance value calibration unit, wherein the capacitance value detection unit is used for detecting an actual capacitance value between an X-axis touch electrode and a Y-axis touch electrode on the surface of a touch display panel, and the X-axis touch electrode and the Y-axis touch electrode are opposite to each other; and the capacitance value calibration unit is connected with the capacitance value detection unit and is used for setting the actual capacitance value into a basic capacitance value. According to the capacitance value self-calibration device and method as well as the touch display device, the problem of false alarm points caused by change of the basic capacitance value or the problem that the touch display panel cannot be recognized when being touched in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a capacitance value self-calibration device, method and touch display device. Background technique [0002] An X-axis electrode layer and a Y-axis electrode layer are arranged on the surface of the projected capacitive touch display panel, and a plurality of X-axis touch electrodes arranged in an array are arranged on the X-axis electrode layer, and a plurality of X-axis touch electrodes in the same line are connected in series. connected; a plurality of Y-axis touch electrodes arranged in an array are arranged on the Y-axis electrode layer, and a plurality of Y-axis touch electrodes in the same row are connected in series. When there is no contact with any conductive object, there will be a fixed capacitance between the opposite X-axis touch electrode and Y-axis touch electrode, and the capacitance value of this capacitance is the basic capacitance value; when a fi...
