What is the principle of capacitive touch integrated machine? Is it an introduction?

Its principle is that the projection capacitive touch screen works by using the current induction of human body. Two ITO conductive circuit modules perpendicular to each other are etched on two layers of ITO conductive glass coatings, which are regarded as sliding bars with continuous changes in X and Y directions. When the current passes through one conductor in the drive line, if there is a signal of capacitance change from the outside, the capacitance node on the other conductor will change. The change of the detected capacitance can be measured by an electronic circuit connected with it, and then converted into a digital signal by an A/D controller, and the position of the (x, y) axis can be obtained by computer operation, so as to achieve the purpose of positioning. The appearance is flat structure, thinner and better looking, and can also be customized. Guangzhou Touch Wo Electronics is quite good. It is a manufacturer of integrated capacitors. You can learn about it.
