  • Patent number: 10542596
    Abstract: 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.

  • Patent number: 10388236
    Abstract: A liquid crystal display device that performs phase inversion drive in which a phase of a polarity of a data voltage is inverted in predetermined timing while performing frame inversion drive in which a positive-polarity data voltage and a negative-polarity data voltage are alternately output to a data line in each one or plurality of frames. In a first frame immediately after the phase is inverted, the source driver outputs a second data voltage to the data line in initial first periods of a horizontal scanning period, the second data voltage being closer to the common voltage than a first data voltage corresponding to input image data, and outputs the first data voltage to the data line in a second period after the first period in the horizontal scanning period.
