Abstract
A driving apparatus for a display is provided. The driving apparatus for a display comprises a reference voltage generator, a digital-to-analog converter, and an output unit. The reference voltage generator generates a plurality of reference voltages, and receives a difference value between two adjacent reference voltages and generates a plurality of sub reference voltages. The digital-to-analog converter selects one of the reference voltages and outputs the selected reference voltage as a first analog signal. The digital-to-analog converter selects one of the sub reference voltages and outputs the selected reference voltage as a second analog signal. The output unit processes, by addition or subtraction, the first and second analog signals for output.
