Abstract
Embodiments relate to estimating power consumption for displaying an image at a display device and sending a load signal indicating expected power consumption for displaying the image to the display device to enable the display device to adjust input voltage at its display integrated circuit (IC). The load signal may be received at a compensation circuit that generates and sends a control signal to a power IC in the display device so that the power IC adjusts its output voltage according to the control signal. In this way, the input voltage at the display IC is maintained relatively constant even when the power consumption changes to display different images.
