Touch screen power supply interference identification processing method

Abstract

The invention discloses a touch screen power supply interference identification processing method, which comprises the following steps of: setting a processor, and preparing to record an input signal; setting a first threshold value, a second threshold value and a third threshold value; collecting contact peripheral channel node data; processing the data to obtain an input signal; comparing whether the input signal is smaller than a first threshold value; comparing whether the input signal is greater than a second threshold value; and comparing the input signal with a third threshold value, judging whether the input signal is smaller than the third threshold value or not, judging the input signal input by the user so as to accurately judge whether the user wears the glove or not, recording the input signal of wearing the glove into a database of the processor, and regularly recalculating the third threshold value in a time node. Therefore, along with time, the third threshold value which is continuously and repeatedly calculated is more accurate, and along with more and more users, more and more types of gloves are worn, so that the judged structure is more and more accurate.

Description

technical field [0001] The present invention relates to the field of processing methods, in particular to a touch screen power supply interference identification processing method. Background technique [0002] Among the currently used touch screens, the use of capacitive touch screens has become more and more popular. Capacitive touch screens use ITO materials, which have low power consumption and long life. The touch screen has been sought after by the market, and it has begun to show the trend of gradually replacing the resistive touch screen. When the finger touches the surface of the screen, a certain amount of charge will be transferred to the human body. The amount of supplementary charge is proportional to the distance of the touch point, which makes it easy for us to calculate the touch position. However, in the current use of touch screens, with the continuous improvement of people's awareness of hygiene and safety, especially in the case of epidemics, the use of t...

[0002] Among the currently used touch screens, the use of capacitive touch screens has become more and more popular. Capacitive touch screens use ITO materials, which have low power consumption and long life. The touch screen has been sought after by the market, and it has begun to show the trend of gradually replacing the resistive touch screen. When the finger touches the surface of the screen, a certain amount of charge will be transferred to the human body. The amount of supplementary charge is proportional to the distance of the touch point, which makes it easy for us to calculate the touch position. However, in the current use of touch screens, with the continuous improvement of people's awareness of hygiene and safety, especially in the case of epidemics, the use of touch screens in public places Contact, people are more cautious. For their own safety, people begin to wear various gloves and touch the touch screen, but the traditional touch screen has poor ability to identify gloves, and because there are too many types of gloves, and the replacement is relatively fast. The more types of gloves, the more difficult it is to identify
