Detailed explanation-1: -Resistive touch screens must be calibrated before they are used to ensure accurate and reliable operation.
Detailed explanation-2: -The nifty thing about capacitive touch screens is that they do not require calibration! The calibration is done ‘in chip’ on the screen itself. However, we still do need to tell the Pi how to read the capacitive chip.
Detailed explanation-3: -Resistive touchscreens, which allow both finger and non-finger input (e.g., glove, stylus), are used in feature phones, global positioning systems (GPS), printers, digital cameras, and larger displays.
Detailed explanation-4: -If you want increased screen contrast and clarity, capacitive touch screens are the preferred option over resistive screens, which have more reflections due to their number of layers. Capacitive screens are also far more sensitive and can work with multi-point inputs, known as ‘multi-touch’.
Detailed explanation-5: -Calibration is necessary when the coordinates of the area touched on the screen are not suf-ficiently close to the coordinates on the display. Without proper calibration, software may not respond correctly when a soft button or icon is pressed.
