Abstract: A method and apparatus for sensing strain in a flexible electronic display. In some implementations, a display controller may be coupled to an electronic display panel. The display controller is configured to receive sensor signals from one or more piezoresistive sensors disposed in the electronic display panel, determine an amount of strain in the electronic display panel based on the received sensor signals, determine a bend angle of the electronic display panel based on the determined amount of strain, and update a configuration of the electronic display panel based at least in part on the determined bend angle. In some implementations, the electronic display panel may be an organic light-emitting diode (OLED) display panel. In some implementations, the electronic display panel may include a polycrystalline silicon (poly-Si) backplane disposed on a flexible substrate, where each of the piezoresistive sensors includes one or more strain gauges formed on the poly-Si backplane.

Abstract: An example method of illuminating an optical fingerprint sensor integrated with a display, where the display includes a fingerprint (FP) pixel region and an outer pixel region exclusive of the FP pixel region, is described. The method includes: processing image data in display driver circuitry configured to drive the display to present an image; adjusting a first brightness setting, during the processing of the image data, corresponding to both the FP pixel region and the outer pixel region to provide illumination for the optical fingerprint sensor; and adjusting a second brightness setting, during the processing of the image data, corresponding to only the outer pixel region.

Abstract: The input devices described herein include force sensor electrodes that use capacitive sensing to measure the force with which an input object (e.g., a finger or stylus) presses down on the input device. To measure this force, the input device includes a compressible layer disposed between a backlight of a display in the input device and a cover window of the display. In one embodiment, the compressible layer is disposed between the backlight and a transparent thin-film transistor (TFT) layer in the display. In one embodiment, the compressible layer includes an air gap which has a thickness defined by adhesive material disposed on at least two edges of the display.
