Low power pulse width modulation by controlling bits order

An electronic display uses pulse-width modulation (PWM) to drive light emitting devices (LEDs) with reduced power consumption. A modified digital word including a modified sequence of bits is generated by modifying a bit sequence of a greyscale value for a sub-pixel. The modified bit sequence includes fewer transitions from a first voltage level to a second voltage level higher than the first voltage level than the bit sequence of the grayscale value. A modified sequence of pulses is generated based on ordering pulses of the PWM signal according to the modified bit sequence. The modified digital word and the modified sequence of pulses are used to control a light emitting device of the electronic display. The reduction in voltage level transitions results in reduced charging of a storage capacitor in the control circuit for the LED, while maintaining brightness level as specified by grayscale value.
