Output driving circuits of output buffers for source driver integrated circuits |
摘要 |
An output driving circuit is provided that may reduce power consumption by decreasing static current leakage in a liquid crystal display device. The output driving circuit of an output buffer of a source driver integrated circuit may include: an output driving unit including a pull-up transistor and a pull-down transistor coupled to a source line driving signal output terminal; and a sub output driving unit configured to perform an output driving operation together with the output driving unit during a normal operation period of an active horizontal synchronization signal and configured to be disabled during a period in which the horizontal synchronization signal is inactive in response to a control signal, in order to reduce static current leakage flowing through the output driving circuit. Current leakage is reduced in the inactive period of a horizontal synchronization signal in an output driving circuit, thereby reducing power consumption of a liquid crystal display device.
