Abstract
A display apparatus comprises a demultiplexing circuit portion that sequentially supplies data signals supplied from a data driving circuit to at least two data lines, and the demultiplexing circuit portion of the display apparatus comprises a switching portion that sequentially supplies the data signals to the at least two data lines based on a voltage of a control line; a voltage controller that controls the voltage of the control line in response to a time-division control signal; and a voltage discharge portion that discharges the voltage of the control line in response to the time-division control signal.
Claims31
A display apparatus comprising a demultiplexing circuit portion that sequentially supplies data signals supplied from a data driving circuit to at least two data lines, the demultiplexing circuit portion comprising:
- a switching portion that sequentially supplies the data signals to the at least two data lines based on a voltage of a control line;
- a voltage controller that controls the voltage of the control line in response to a time-division control signal;
- and
- a voltage discharge portion that discharges the voltage of the control line in response to the time-division control signal.
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,
- wherein the demultiplexing circuit portion comprising:
- a voltage controller that controls voltages of the first to ith control lines in response to first to ith time-division control signals;
- a switching portion that sequentially supplies data signals supplied from the first to n/ith output channels to the n data lines based on the voltages of the first to ith control lines;
- and
- a voltage discharge portion that discharges the voltages of the first to ith control lines in response to the first to ith time-division control signals.
