Abstract: A display device include a first light emitting diode (LED), a second LED, and at least one processor of a driver. The processor drives the first LED and the second LED. The processor determines a first pulse width associated with the first LED and a second pulse width associated with the second LED based on a level of brightness to be emitted by the first LED and the second LED. The processor also receives a gap clock and determines a first pulse start time and a first pulse end time for the first LED based on the first pulse width. Moreover, the processor determines a second pulse start time and a second pulse end time for the second LED based on the first pulse end time, the second pulse width, and/or the gap clock, in which the first pulse end time and the second pulse end time are different.

Abstract: Systems and methods for preserving a pulse width modulation (PWM) resolution while increasing the frequency of a pulse width modulation (PWM) clock are provided. An electronic display backlight system may include a backlight element and backlight dimming circuitry. The backlight element may be driven according to a pulse width modulation (PWM) signal over a PWM clock cycle equal to a multiple M of a baseline PWM clock frequency associated with a baseline PWM resolution. The backlight dimming circuitry may receive a brightness code of the baseline PWM resolution and generate the PWM signal at least in part by dividing the brightness code by M.

Abstract: Aspects of the subject technology relate to an electronic device with a display. The display includes an array of light-emitting diodes. The array includes a plurality of subarrays of the light-emitting diodes. At least one driver circuit is coupled to the array of light-emitting diodes. The at least one driver circuit is configured to generate an adaptive pulse-width modulated (PWM) signal to control at least one subarray of the plurality of subarrays of the light-emitting diodes. The adaptive PWM signal is designed with each pulse of a group having a pulse width W, each pulse width being reduced until reaching a threshold pulse width, and one pulse being removed from the group of pulses.
