Abstract
A display driving device includes a first source amplifier that receives first display data and supplies a first pixel voltage to a first pixel based on the received first display data, and a second source amplifier that receives second display data and first control data and supplies a second pixel voltage to a second pixel based on the received second display data and first control data. The second source amplifier has a first stage in which a first process is performed on an input signal based on the second display data, and a second stage in which a second process is performed on the first processed input signal to output the second pixel voltage. The first source amplifier may be configured to conditionally supply the first pixel voltage to the second pixel.
