Abstract: An electronic device may have a flexible display such as an organic light-emitting diode display. A strain sensing resistor may be formed on a bent tail portion of the flexible display to gather strain measurements. Resistance measurement circuitry in a display driver integrated circuit may make resistance measurements on the strain sensing resistor and a temperature compensation resistor to measure strain. A crack detection line may be formed from an elongated pair of traces that are coupled at their ends to form a loop. The crack detection line may run along a peripheral edge of the flexible display. Crack detection circuitry may monitor the resistance of the crack detection line to detect cracks. The crack detection circuitry may include switches that adjust the length of the crack detection line and thereby allow resistances to be measured for different segments of the line.

Abstract: An electronic device includes processors that generate image data. The electronic device also includes an electronic display that displays the image data over a first frame duration by programming a first row of display pixels with the image data. The electronic display also displays the image data over the first frame duration by causing the first row of display pixels to emit light for an emission duration that is based at least in part on a first luminance of the image data. The electronic display further displays the image data over the first frame duration by resetting the first row of pixels before an end of the first frame duration.

Abstract: An electronic display includes an active area having an array of pixels. The electronic display also includes multiple data power rails coupled to the active area that supply power to the array of pixels. The electronic display further includes data driving circuitry coupled to the multiple data power rails that drive the array of pixels. The electronic display also includes a controller coupled to the data driving circuitry having a processor. The processor causes the array of pixels to emit light based on a display brightness value. The processor also causes a pixel of the array of pixels to emit light at a brightness of gray level 0 by dynamically adjusting a data power rail of the multiple data power rails.
