DISPLAY DRIVE CIRCUIT AND STANDBY POWER REDUCTION METHOD THEREOF

摘要

A display driving circuit in accordance with the inventive concepts may include a source amplifier. The source amplifier may include an output transistor configured to amplify an input signal to generate an output signal, and charge a source line of a display panel using the output signal. The source amplifier may include an output transistor switch configured to control the output transistor, and a switch control block configured to receive configuration bits including on/off time information of the output transistor switch to generate a switch control signal. The on/off time information includes information for turning on the output transistor switch in synchronization with a horizontal synchronous signal associated with the display panel, and information for turning off the output transistor switch at a time when the source line of the display panel is charged to a desired charge level.
