Display apparatus

A display apparatus comprising:

• n data lines;
• a demultiplexing circuit portion connected to first to ith (i is a natural number of 2 or more) control lines and connected to the n data lines;
• and
• a data driving circuit having first to n/ith output channels connected to the demultiplexing circuit portion,
• the demultiplexing circuit portion including:
• a voltage controller for controlling voltages of the first to ith control lines in response to first to ith time-division control signals and auxiliary signals partially overlapped with each of the first to ith time-division control signals;
• a switching portion for sequentially supplying data signals supplied from the first to n/ith output channels to the n data lines based on the voltage of each of the first to ith control lines;
• and
• a voltage discharge portion for discharging the voltages of the first to ith control lines in response to the first to ith time-division control signals.

A display apparatus including:

• a plurality of pixels on a substrate;
• a plurality of data lines on the substrate, a data line connected to a corresponding column of pixels;
• a first control line connected to a first set of data lines;
• a second control line connected to a second set of data lines;
• and
• a demultiplexing circuit configured to receive a plurality of data signals from a data driving circuit for supply to the plurality of data lines during a horizontal period that includes at least a first sub-horizontal period and a second sub-horizontal period subsequent the first sub-horizontal period, the plurality of data signals including first data signals for supply to the first set of data lines during the first sub-horizontal period, and second data signals for supply to the second set of data lines during the second sub-horizontal period, the demultiplexing circuit including:
• a first set of switches connected to the first set of data lines and to a first control line, the first set of switches configured to turn on for the first sub-horizontal period to supply the first data signals to the first set of data lines,
• a first discharge portion connected to the first control line, the first discharge portion configured to discharge the first control line when turned on,
• a second set of switches connected to a second set of data lines and to a second control line, the second set of switches configured to turn on for the second sub-horizontal period to supply the second data signals to the second set of data lines, and
• a second discharge portion connected to the second control line, the second discharge portion configured to discharge the second control line when turned on.
