    Abstract: An electronic device may be provided with an ambient light sensor, a display that displays image content, and control circuitry. The control circuitry may adjust a peak allowable brightness of the display based on an ambient light brightness and based on the image content being displayed. For example, the control circuitry may analyze frames of display data to determine an average pixel luminance level. Low average pixel luminance levels correspond to mostly dark image content, whereas high average pixel luminance levels correspond to mostly light image content. When an electronic device is outdoors and displaying mostly dark images with low average pixel luminance levels, the control circuitry may take advantage of the display's maximum achievable brightness to improve readability. When an electronic device is outdoors and displaying mostly light images with high average pixel luminance levels, the control circuitry may scale the maximum allowable brightness down to reduce power consumption.

    Abstract: An electronic device includes processors that generate image data. The electronic device also includes an electronic display that displays the image data over a first frame duration by programming a first row of display pixels with the image data. The electronic display also displays the image data over the first frame duration by causing the first row of display pixels to emit light for an emission duration that is based at least in part on a first luminance of the image data. The electronic display further displays the image data over the first frame duration by resetting the first row of pixels before an end of the first frame duration.

    Abstract: Methods, systems, and apparatuses for controlling an emission of the light emitting devices are described herein. The light emitting devices may be light emitting diode (LED) devices including μLED devices or organic LED (OLED) devices. Emission control of the LED may be performed using a micro-scale driving circuit (e.g., μDriver) containing drive transistors for constant current driving of the light emitting devices. One embodiment provides for a display driver hardware circuit comprising a thin film transistor (TFT) backplane and an integrated circuit to switch and drive a plurality of LED devices, the integrated circuit including emission logic to generate an emission pulse to an LED device, the emission logic including comparator logic having a relaxed comparator offset, the comparator logic to compare a voltage from a storage capacitor on the TFT backplane to a reference voltage to control a length of the emission pulse provided by the emission logic.

    Abstract: An electronic display includes a display panel, which includes an array of pixels and a driver configured to activate and deactivate the emission of light from each of the pixels in the array. The electronic display also includes a panel driver configured to generate and transmit an emission interrupt signal to the driver, wherein the emission interrupt signal causes the driver to deactivate the emission of light from all pixels in the array for a set period of time prior to a refresh of a line of pixels in the array.
