Abstract
A display is disclosed where in an optimization mode, the controller transmits a first lock signal having a pulse waveforms to a first source driver circuit among source driver circuits, receives a second lock signal having pulse waveforms from a last source driver circuit that receives the first lock signal, and transmits phase loop fixed data for recovering a frequency and a phase of a clock to each of the source driver circuits when the second lock signal is received, and in the display mode, the controller transmits a first lock signal having a preset voltage level to the first source driver circuit, receives a second lock signal having a plurality of preset voltage levels from a last source driver circuit, and supplies an image signal and control data to each of the source driver circuits when the second lock signal is received.
