Abstract:
A display driver comprises drop amount calculation circuitry and digital gamma correction circuitry. The drop amount calculation circuitry is configured to calculate a drop amount of a power source voltage supplied to a display panel from a setting value. The digital gamma correction circuitry is configured to perform digital gamma correction on an input image data based on the drop amount.
