Abstract
A method, computer program product and system for protecting content includes a mobile device screen including a plurality of pixels, whereby each of the plurality of pixels have first sub-pixel units that include a first viewing angle and second sub-pixel units that include a second viewing angle. Within each of the plurality of pixels, the first sub-pixel units are adjacent to the second sub-pixel units. A processing unit is coupled to the mobile device screen and determines a portion of the mobile device screen that displays sensitive content. The processing unit obscures the sensitive content displayed on the portion of the mobile device screen by deactivating the first sub-pixel units at the portion of the mobile device screen that displays the sensitive content and activates the second sub-pixel units at the portion of the mobile device screen that displays the sensitive content.
