Abstract:
1. An electronic display comprising: a display panel; and a backlight assembly configured to illuminate the display panel at least partly by driving a backlight element, the backlight assembly comprising backlight short-circuit detection circuitry configured to detect a recent or current value of a feedback voltage associated with the backlight element and determine when a short circuit has occurred based at least in part on a comparison between the recent or current value of the feedback voltage and an expected value of the feedback voltage, wherein the expected value of the feedback voltage changes over time and the backlight assembly comprises configuration memory, wherein the backlight short-circuit detection circuitry is configured to determine the expected value of the feedback voltage based at least in part on a curve stored in the configuration memory, wherein the curve represents the expected value of the feedback voltage over time.
