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： 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.
