Abstract
A device for increasing a slew rate of a driving amplifier includes a driving amplifier, a slew rate improvement circuit, and a controller. The driving amplifier is configured to amplify an input voltage and output an output voltage. The slew rate improvement circuit is configured to provide or receive a current to increase the slew rate of the driving amplifier. The controller is configured to control an operation of the slew rate improvement circuit based on a difference between a first code corresponding to the input voltage of the driving amplifier during a current horizontal line time and a second code corresponding to the input voltage during a next horizontal line time.
