example 1

[0122] Figure 18 is a flow chart of a signal processing method shown according to an exemplary embodiment, such as Figure 18 As shown, the method includes the following steps:

[0123] Step 181 , acquiring touch signal values ​​of touch nodes in the target touch channel included in the touch panel in units of touch channels. Here, each target touch channel includes 15 touch nodes.

[0124] Step 182, judging whether the touch signal value of the touch node in the target touch channel is within a preset range. If it is within the preset range, execute step 183; if it is not within the preset range, execute step 184.

[0125] Step 183, when the touch signal value of the touch node in the target touch channel is within (-50, 50), that is, the maximum touch signal value of the touch node in the target touch channel is in (-50, 50), adopt the first noise filtering method to denoise. See Figure 19 , columns 1, 2 and 9 are denoised by the first noise filtering method (such as...

Abstract

The invention relates to a signal processing method, and the method is applied to a touch panel and comprises the following steps: acquiring a touch signal value of a touch node in a touch channel contained in the touch panel, wherein one of the touch control channels comprises one or more rows of the touch control nodes, or one of the touch control channels comprises one or more columns of the touch control nodes; determining a noise filtering mode according to the touch signal value of each touch node in the touch channel; according to the noise filtering mode, performing noise filtering processing on the touch signal value to obtain a filtering signal; and determining a touch operation acting on the touch panel based on the filtering signal.

Description

technical field [0001] The present disclosure relates to the field of signal processing, and in particular, to a signal processing method, device, equipment, and storage medium. Background technique [0002] With the rapid development of science and technology, smart terminals using touch screens are becoming more and more popular among the public. People can operate the terminal by directly clicking the touch screen, and the interaction of the man-machine interface becomes simpler and more convenient. [0003] The touch function and display function of a traditional touch screen are independently controlled by two chips. The touch screen based on Touch and Display Driver Integration (TDDI, Touch and Display Driver Integration) technology integrates a touch chip and a display chip into a single chip, replacing the traditional touch module. The touch screen based on the touch and display driver integration technology integrates the touch sensor into the display, which makes...
