摘要： Disclosed is a liquid crystal display panel driving circuit for driving a liquid crystal display panel with a resolution of N bits. N-bit digital data including upper X bits and lower Y bits is inputted. The liquid crystal display panel driving circuit includes a resistor string unit according to areas, a DAC converter switching unit according to areas, and an interpolation amplifier. The resistor string unit outputs analog reference voltages at different ratios according to three areas. The DAC converter switching unit receives the N-bit digital data, selects (Y+1) analog voltages from the analog reference voltages based on the upper X bits, outputs the (Y+1) analog voltages, and outputs the (Y+1) analog voltages of different combinations based on the lower Y bits. The interpolation amplifier receives the (Y+1) analog voltages and generates an interpolated output voltage by setting weights for the (Y+1) analog voltages by using multi-factors.

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.
