Abstract
A method of identifying a crack in a touchscreen display system includes measuring a distance between a first layer of the touchscreen display system and a second layer of the touchscreen display system, detecting a change in the distance at a portion of the touchscreen display system, identifying a crack in the first layer at the portion of the touchscreen display system based on the change in the distance, and adjusting one or more parameters of the touchscreen display system based on the crack in the first layer.
Claims20
A method of identifying a crack in a touchscreen display system comprising:
- measuring a distance between a first layer of the touchscreen display system and a second layer of the touchscreen display system;
- detecting a change in the distance at a portion of the touchscreen display system;
- identifying a crack in the first layer at the portion of the touchscreen display system based on the change in the distance;
- and
- adjusting one or more parameters of the touchscreen display system based on the crack in the first layer.
A system for identifying a crack in a touchscreen display system comprising:
- a central processor unit (CPU);
- a non-volatile memory operatively connected to the CPU;
- and
- a crack detection module configured to detect cracks in a layer of the touchscreen display system, the crack detection module including computer readable program code embodied therewith, the computer readable program code, when executed by the CPU, causes the CPU to:
- measure a distance between a first layer of the touchscreen display system and a second layer of the touchscreen display system;
- detect a change in the distance at a portion of the touchscreen display system;
- identify a crack in the first layer at the portion of the touchscreen display system based on the change in the distance;
- and
- adjust one or more parameters of the touchscreen display system based on the crack in the first layer.
A computer program product for detecting cracks in a touchscreen display system comprising:
- a computer useable medium including a computer readable program, wherein the computer readable program, when executed on a computer, causes the computer to:
- measure a distance between a first layer of the touchscreen display system and a second layer of the touchscreen display system;
- detect a change in the distance at a portion of the touchscreen display system;
- identify a crack in the first layer at the portion of the touchscreen display system based on the change in the distance;
- and
- adjust one or more parameters of the touchscreen display system based on the crack in the first layer.
