Abstract
An embodiment of the invention may include a method, computer program product and system for operating an electronic display device. An embodiment may include displaying, using a first refresh rate, first content on a first partition of a display area of the electronic display device. An embodiment may include displaying, using a second refresh rate, second content on a second partition of the display area of the electronic display device. The first refresh rate is different from the second refresh rate.
Claims20
A computer-implemented method for operating an electronic display device, the method comprising:
- partitioning a display area of the electronic display device into one or more areas for protection against external storage, wherein the partitioning is based on a type of content displayed within the one or more areas, and wherein the type of content displayed comprises sensitive information;
- displaying within the one or more areas the type of content using a first refresh rate in combination with an applied visual effect, wherein the combination of the first refresh rate and the applied visual effect visually distorts the type of content displayed within the one or more areas so as to prevent storage, via a screen capture or photographic image taken with an external device, of the type of content displayed within the one or more areas;
- and
- displaying, using a second refresh rate, second content displayed within one or more other display area partitions of the electronic display device, wherein the first refresh rate is different from the second refresh rate.
A computer program product for operating an electronic display device, the computer program product comprising:
- one or more non-transitory computer-readable storage devices and program instructions stored on at least one of the one or more non-transitory computer-readable storage devices, wherein the program instructions are executable by a computer, the program instructions comprising:
- program instructions to partition a display area of the electronic display device into one or more areas for protection against external storage, wherein the partitioning is based on a type of content displayed within the one or more areas, and wherein the type of content displayed comprises sensitive information;
- program instructions to display within the one or more areas the type of content using a first refresh rate in combination with an applied visual effect, wherein the combination of the first refresh rate and the applied visual effect visually distorts the type of content displayed within the one or more areas so as to prevent storage, via a screen capture or photographic image taken with an external device, of the type of content displayed within the one or more areas;
- and
- program instructions to display, using a second refresh rate, second content displayed within one or more other display area partitions of the electronic display device, wherein the first refresh rate is different from the second refresh rate.
A computer system for operating an electronic display device, the computer system comprising:
- one or more processors, one or more computer-readable memories, one or more non-transitory computer-readable storage devices, and program instructions stored on at least one of the one or more non-transitory computer-readable storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:
- program instructions to partition a display area of the electronic display device into one or more areas for protection against external storage, wherein the partitioning is based on a type of content displayed within the one or more areas, and wherein the type of content displayed comprises sensitive information;
- program instructions to display within the one or more areas the type of content using a first refresh rate in combination with an applied visual effect, wherein the combination of the first refresh rate and the applied visual effect visually distorts the type of content displayed within the one or more areas so as to prevent storage, via a screen capture or photographic image taken with an external device, of the type of content displayed within the one or more areas;
- and
- program instructions to display, using a second refresh rate, second content displayed within one or more other display area partitions of the electronic display device, wherein the first refresh rate is different from the second refresh rate.
