CIRCUIT FOR DRIVING SOURCE WIRE AND DISPLAY DEVICE HAVING THE SAME

摘要

A source driving circuit and a display apparatus including the same are provided to enhance charge rate of a pixel unit by reducing current consumption of a switching unit for shunting m-th and (m+1)-th source lines. A source driving circuit includes an output buffer(217) and first and second switching units(233a,233b). The output buffer outputs a first polarity voltage and a second polarity voltage inverted from the first polarity voltage during an output interval having first and second intervals. The first switching unit delivers the first and second polarity voltages to m-th and (m+1)-th source lines during the first interval and blocks outputs of the first and second polarity voltages during the second interval. The second switching unit, which shunts m-th and (m+1)-th source lines during the second interval, includes first, second, and third switching elements. The first switching element is connected with the m-th source line. The second switching element is connected in series with the first switching element and connected to the (m+1)-th source line. The third switching element is connected in parallel with the first and second switching elements.
