Abstract: Systems, methods, and devices are described that may mitigate pixel and touch crosstalk noise. A touch processing system may compensate touch scan data to reduce the noise based on a luminance value. An image processing system may determine the luminance value based on image data and a display brightness value of an electronic display. Using the compensated touch scan data, the touch processing system may determine a proximity of a capacitive object to at least one touch sense region of the electronic display.

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.

Abstract: The present disclosure is directed to estimating and modulating peak luminance of the display substantially in real-time to allow very bright pixels to be shown on the electronic display as long as the total electrical energy drawn by the electronic display does not exceed a threshold. The amount of electrical energy that is being drawn by the electronic display may be estimated from the image data by counting the number of rows of pixels that are emitting pulses in discrete bins of time. Because the pulses draw a predictable amount of electrical energy per row per time bin, the amount of electrical energy drawn by the electronic display may be estimated substantially in real time. The image data on the electronic display may therefore be modulated to avoid drawing too much electrical energy from the power source of the electronic device while permitting a high dynamic range.
