Abstract
A slew rate controller includes an amplifier configured to operate with a first driving voltage and a second driving voltage, and generate an output voltage by using an image data voltage inputted at a first time point; an output switch configured to apply the output voltage to an external panel load according to a first control signal at the first time point; a first switch connected between one end of the output switch and the amplifier; and a second switch connected between the other end of the output switch and the amplifier.
