摘要： 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.

摘要： A layout of a liquid crystal display driving circuit is capable of minimizing an area which the layout occupies. The layout of the liquid crystal display driving circuit transmits positive analog voltages and negative analog voltages to a liquid crystal display, and includes a digital-to-analog converter (DAC) block and a buffer block. The DAC block has N/2 positive DACs generating the respective positive analog voltages corresponding to corresponding digital data using a positive reference voltage, where N is the integer, and N/2 negative DACs generating the respective negative analog voltages corresponding to corresponding digital data using a negative reference voltage. The buffer block has N/2 positive and negative buffers, which buffer the N/2 positive and negative analog voltages, and are alternately arranged. The N/2 positive and negative DACs are divided into groups one by one or in twos or more, and the groups are alternately arranged.
