Abstract: A non-transitory computer-readable storage medium can include instructions stored thereon that, when executed by at least one processor, are configured to cause a computing device to determine, in response to a change in a refresh rate of a display, an encoded intensity of at least a portion of an image presented by the display, determine that the encoded intensity is within a predetermined range, and based on determining that the encoded intensity is within the predetermined range, adjust an intensity of a signal for the portion of the image.

Abstract: This document describes systems and techniques directed at compensating for voltage losses in organic light-emitting diode (OLED) displays. In aspects, a computing device having an OLED display and a luminance manager is configured to receive an indication of a luminance that is, or is intended to be, displayed by pixels of the OLED display. Responsive to and based on the received indication of luminance and a voltage loss, the luminance manager determines a luminance modification for the pixels of the OLED display. Based on the determined luminance modification, the luminance manager modifies the luminance that is displayed or modifies the luminance that is intended to be displayed by the pixels of the OLED display effective to compensate for the voltage loss.
