NOISE REDUCTION METHOD, TOUCH DISPLAY APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
First Claim
1. A noise reduction method, wherein the noise reduction method is applied to a touch display apparatus, several touch detection nodes are disposed on the touch display apparatus, and the method comprises:
- obtaining noise data of each touch detection node;
obtaining characteristic values based on the noise data;
performing fitting processing on noise data of a target node and the characteristic values, to obtain a fitting function in which the characteristic values are used as an independent variable and the noise data of the target node is used as a dependent variable, wherein the target node is a touch detection node to be noise reduced;
substituting the characteristic values into the fitting function, to obtain fitting data corresponding to the characteristic values; and
using differences between the fitting data and the noise data of the target node as noise reduced data.

Abstract
Embodiments of the present disclosure provide a noise reduction method. The noise reduction method is applied to the touch display apparatus on which several touch detection nodes are disposed, and the noise reduction method includes: obtaining noise data of each touch detection node (101); obtaining characteristic values based on the noise data (102); performing fitting processing on noise data of a target node and the characteristic values, to obtain a fitting function in which the characteristic values are used as an independent variable and the noise data of the target node is used as a dependent variable (103), where a target node is a touch detection node to be noise reduced; substituting the characteristic values into the fitting function, to obtain fitting data corresponding to the characteristic values (104); and using differences between the fitting data and the noise data of the target node as noise reduced data (105).
