Problems solved by technology

[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 u

Example Embodiment

[0021]In order to make the techniques, creative features, objective and efficacy of the present invention, and the embodiments are further illustrated in connection with the specific embodiments.

[0022]Such asfigure 1As shown, a touch screen power source interference identification processing method includes the following steps:

[0023]S1, set the processor, prepare the input signal;

[0024]S2, set the first threshold, the second threshold, and the third threshold;

[0025]S3, collect the peripheral channel node data of contacts;

[0026]S4, process the data to obtain an input signal;

[0027]S5, the input signal is compared to the first threshold, whether it is less than the first threshold, if it is smaller, if it is not less than the first threshold, it is indicated as a non-contact signal, and does not process;

[0028]S6, the input signal is compared to the second threshold value, whether it is greater than the second threshold, if it is greater than the second threshold, then enter S7, if the ...

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...
