阅读说明：本技术 降噪方法、触控显示装置和计算机可读存储介质 (Noise reduction method, touch display device and computer readable storage medium ) 是由 陈曦 于 2018-10-31 设计创作，主要内容包括：一种降噪方法、触控显示装置和计算机可读存储介质。降噪方法,应用于触控显示装置,触控显示装置上设置有若干触摸检测节点,包括：获取各触摸检测节点的噪声数据(101)；根据噪声数据获取特征值(102)；对目标节点的噪声数据和特征值进行拟合处理,得到以特征值为自变量,以目标节点的噪声数据为因变量的拟合函数(103)；目标节点为待降噪的触摸检测节点；将特征值代入拟合函数,得到与特征值对应的拟合数据(104)；将拟合数据和目标节点的噪声数据的差值,作为降噪后的数据(105)。降低了硬件成本,无需受固定采样频率限制的影响,而且可对非直流分量的噪声干扰进行滤除。(A noise reduction method, a touch display device and a computer readable storage medium are provided. The noise reduction method is applied to a touch display device, wherein a plurality of touch detection nodes are arranged on the touch display device, and the noise reduction method comprises the following steps: acquiring noise data (101) of each touch detection node; acquiring a characteristic value (102) according to the noise data; fitting the noise data and the characteristic value of the target node to obtain a fitting function (103) with the characteristic value as an independent variable and the noise data of the target node as a dependent variable; the target node is a touch detection node to be subjected to noise reduction; substituting the characteristic value into a fitting function to obtain fitting data (104) corresponding to the characteristic value; and taking the difference value of the fitting data and the noise data of the target node as the data after noise reduction (105). The hardware cost is reduced, the influence of the limitation of a fixed sampling frequency is not needed, and the noise interference of the non-direct-current component can be filtered.)
