Abstract
Provided herein are devices and methods relating to detecting and/or correcting distortions and other events that can occur to a display surface so that a desired image is viewed despite the presence of a distortion in the display surface itself.
Claims45
A self-correcting deformable display comprising:
- a deformable display comprising at least a first pixel and a second pixel;
- a processor in communication with the deformable display;
- and
- at least one strain sensor incorporated into the deformable display, wherein the strain sensor is in communication with the processor, and wherein the processor is in communication with the deformable display.

A self-correcting deformable display, the display comprising:
- a display substrate;
- an array of strain sensors associated with the display substrate;
- a processor configured to generate a distortion map from the array of strain sensors, wherein the distortion map comprises a collection of strain values from the array of strain sensors, and wherein the distortion map represents the distortion of an original desired image given a distortion to the display substrate;
- and
- a distortion compensation filter, the filter configured to use the distortion map to adjust the original desired image to a compensated image that can be displayed on the display substrate, wherein the compensated image compensates for the distortion to produce an appearance of a compensated desired image when the display substrate is distorted.
A method of providing a self-correcting image, the method comprising:
- providing a deformable display;
- distorting the display to provide a distorted deformable display;
- measuring at least one amount of distortion of the display resulting from distorting the display to create a distortion map;
- providing an original image;
- using the distortion map to adjust the original image to create a compensated image;
- and
- displaying the compensated image on the distorted deformable display, wherein the compensated image has an appearance that is similar to the original image when displayed on the distorted deformable display.

A method of calibrating a pixel intensity, the method comprising:
- providing a flexible display surface comprising an array of pixels, wherein the display surface comprises at least a first axis of the display, a second axis of the display, and a center of the display;
- determining a global scale factor of the first axis and the second axis;
- determining the center of the display;
- determining a displacement of at least one pixel from a first position to a second position, wherein the first position is where the pixel is when the flexible display surface is at rest, and wherein the second position is where the pixel is when the flexible display surface is deformed;
- and
- calibrating the pixel intensity to compensate for the displacement.
