The control circuitry may include feedforward control and a feedback control for a power supply for the light-emitting diodes. The feedforward control may include host circuitry for the device that determines a maximum zone current, a maximum row current, and the maximum row-to-row current step for an upcoming backlight frame while a current backlight frame is being executed. A headroom voltage for the upcoming backlight frame is determined based on the maximum zone current, the maximum row current, and/or the maximum row-to-row current step and provided to the power supply so that the power supply can settle at a corresponding supply voltage before the upcoming backlight frame is executed. The feedback control utilizes dynamic thresholds determined for each backlight frame to fine tune the feedforward-determined headroom voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive headroom adjustment systems and methods for electronic device displays","description":"Aspects of the subject technology relate to control circuitry for light-emitting diodes.
