Abstract: Methods and systems for compensating display panel operations providing a current from power circuitry over a first path between a display panel and the power circuitry are provided. A sensing current may be injected into the first path via a second path between the power circuitry and the first path. An equivalent series resistance (ESR) of the first path may be calculated using a third path and the sensing current. A processor may compensate for electrical fluctuations from the power circuitry to the display panel based at least in part on the measured ESR.

Abstract: An electronic display includes a display panel. The display panel includes a pixel array and receives a supply voltage. The display panel also includes a panel driver configured to generate a gate line voltage. The panel driver also supplies the gate line voltage to the display panel based on a comparison between the gate line voltage and the supply voltage.
