Abstract: Aspects of the subject technology relate to electronic devices with displays. A display may include an array of display pixels each having a drive transistor and an organic light-emitting diode. A pulse-width-modulated current may be provided to the organic light-emitting diode during each display frame to compensate for an on-bias compensation applied to the drive transistor between display frames. The pulse-width-modulated current may be provided with a pulse-width-modulation ratio that decreases over the course of each display frame. The decrease of the pulse-width-modulation ratio for each display frame may be determined based on a peak luminance for that display frame. The reduction in flicker provided by the pulse-width-modulated current may facilitate operation of the display with a reduced refresh rate, thereby reducing power consumption by the display.

Abstract: Touch induced flicker for variable refresh rate (VRR) displays can be reduced by adjusting one or more voltages. Synchronization of touch sensing operations after an immediate exit can introduce flicker issues into the VRR display. In some examples, the touched induced flicker can be reduced or eliminated by tuning the voltage on a common electrode (Vcom) to a tuning point that reduces a maximum error below a threshold, irrespective of refresh rate. In some examples, touch induced flicker can be reduced or eliminated by monitoring average Vcom, and when the change in average Vcom exceeds a threshold, Vcom can be adjusted to counteract the change in average Vcom due to the variable refresh rate and/or immediate exit. In some examples, touch induced flicker can be reduced or eliminated by applying a direct current (DC) pedestal to pixel gate lines during touch sensing scans.
