  • Systems and methods for two-dimensional backlight operation
    Patent number: 11967290
    Abstract: An electronic display device has a panel that operates in conjunction with a light-emitting diode (LED) backlight. The device “slopes” or gradually ramps a change in brightness of an LED based on a target brightness value of the LED, a current brightness value of the LED, and temperature at the LED. The device also may limit power to the backlight based on an estimated power consumption of a current row of LEDs of the backlight and power consumption of the other rows of LEDs. The device also may determine a reduced voltage to supply to an LED based on a current to supply to the LED to cause the LED to operate. The device also may send an interrupt to the backlight to block updates to the backlight while image content is written to pixels of the panel. The device further compensates for aging of and temperature at an LED.

  • Backlight reconstruction and compensation-based throttling
    Patent number: 11842700
    Abstract: Throttling circuitry may throttle the backlight reconstruction via backlight reconstruction and compensation circuitry in a display pipeline when power may be limited. This throttling of the display pipeline may limit a number of cycles that may be used for performing backlight reconstruction and compensation.
