Abstract:
Disclosed is a data driving circuit including a noise filter, first through third voltage generators, and an output circuit. The noise filter receives a driving voltage and removes noise from the driving voltage to output a filtered driving voltage. The first voltage generator outputs a first voltage, a second voltage, and a third voltage. The second voltage generator generates a first reference voltage based on the filtered driving voltage, the first voltage, and the second voltage. The third voltage generator generates a second reference voltage based on the filtered driving voltage, the second voltage, and the third voltage. The output circuit outputs a data signal of a voltage level corresponding to an image signal based on the first reference voltage and the second reference voltage.
