OUTPUT CIRCUIT AND SWITCHING CIRCUIT OF DISPLAY DRIVING APPARATUS

摘要

The present invention relates to an output circuit of a display driving apparatus for satisfying low power specifications. The output circuit includes an output buffer part which buffers a pair of input signals with reversed polarity and outputs a pair of output signals; and a switching part which transmits the output signal for an output range to a part of output terminals through a direct path or a cross path, and shares charging of the output terminal by using the middle voltage of a pulldown voltage and the pullup voltage of the output buffer part in the charge sharing range between the repeated output ranges.
