Abstract
A display driving circuit and method is capable of minimizing the residual image of a display panel as well as consumption electric current. The display driving circuit generates driving signals corresponding to valid data and black data and transmits the driving signals to a display panel, and includes N data selection switches (where N is the integer), N buffers, N buffer output selection switches, and multiple charge sharing switches. The N data selection switches select one of the valid data and the black data. The N buffers buffer the signal selected by the respective data selection switches. The N buffer output selection switches switch outputs of the buffers to output the respective driving signals. The multiple charge sharing switches connect the neighboring pairs of the driving signals.
