Title
(EN) Method to recover permanent set in a foldable display
Abstract
(EN)

A method, electronic device, and computer program product for countering a semi-permanent deformation at an area of a foldable display. The method monitors a time duration that the display is in the angled position. The method includes measuring a temperature associated with at least one area of the display while the display is in the angled position. In response to the display remaining in the angled position for greater than a calculated period of time, the method determines a degree of semi-permanent deformation associated with the at least one area of the display. The method further triggers an increase in temperature at the at least one area of the display to counter the degree of semi-permanent deformation.
