Abstract
An electronic device includes a foldable touch screen having first and second portions and a bendable intermediate portion connecting the first portion to the second portion. The foldable touch screen has a capacitive touch matrix therein. A touch screen controller acquires touch data from the capacitive touch matrix, calculates strength values of nodes of the capacitive touch matrix based upon the acquired touch data, calculates a first value, the first value being an average strength of nodes of the capacitive touch matrix located in the first portion of the foldable touch screen, calculates a second value, the second value being an average strength of nodes of the capacitive touch matrix located in the second portion of the foldable touch screen, and determines that the foldable touch screen is in a closed position based upon the first value and the second value both being greater than a first given strength value.
