Abstract: Disclosed is a source driver integrated circuit with an improved slew rate by disposing a switching unit, which operates as a resistance component during display driving, before the feedback line of an output buffer. According to the source driver integrated circuit with an improved slew rate, a switching unit, which operates as a resistance component when a signal is transferred, is disposed in the feedback loop of an output buffer, so that the resistance component is not shown to a panel load, thereby improving the slew rate of an output signal. In addition, the improved slew rate makes it possible to easily implement an image through a display.

Abstract: In a source driver output circuit of a flat panel display device, first and second latch units receive image data and store the received image data. A D/A converter converts the image data into a data voltage. An output buffer unit outputs the data voltage to a data line. A switching control unit decides whether or not the data voltages of two image data of the same channel among image data of horizontal lines adjacent to each other, stored in the first and second latch units, belong to the same grayscale voltage range, and outputs a switching control signal based on the decided result. A multiplexer unit selects a pre-charge voltage in response to the switching control signal or continuously maintains a connection state between a corresponding channel of the output buffer unit and the corresponding data line.
