1. A voltage and phase compensation circuit comprising:
a first inverting adder configured to add and invert a plurality of panel signals to output a first inverted signal;
a second inverting adder configured to add and invert feedback signals obtained from delayed panel signals and the first inverted signal to output a second inverted signal; and
a coupler configured to combine the first inverted signal and the second inverted signal.
