Abstract
A power supply unit adapts based on an image to be displayed by a display panel. The power supply unit includes a controller circuit for generating a power control signal, and a power supply circuit for generating one or more power supply voltages having a waveform based the power control signal. The controller circuit receives a set of configuration parameters from a display device and generates the power control signal based on the set of configuration parameters. The configuration parameters are stored in a look-up table of the display device.
