raspberry 7 inch touch screen setup

raspberry 7 inch touch screen setup.Capacitive sensing touch screens are divided into two categories , self-capacitance sensing and mutual capacitance sensing. The self-capacitance screen is made of ITO ( a transparent conductive material ) on the glass surface into horizontal and vertical electrode arrays, and these horizontal and vertical electrodes form a capacitor with the ground, respectively. This capacitor is generally called self-capacitance. During touch detection, the self-capacitance screen sequentially detects the horizontal and vertical electrode arrays respectively, and determines the horizontal and vertical coordinates respectively according to the change in capacitance before and after the touch, and then combines them into planar touch coordinates. The mutual capacitance screen also uses ITO to make lateral and vertical electrodes on the glass surface . The difference between it and the self-capacitance screen is that the capacitors will form where the two groups of electrodes cross, that is, the two groups of electrodes form the two poles of the capacitor.
