Abstract:
A display driver circuit and a display device are provided. The display driver circuit may have positive and negative resistor strings that are symmetrically formed and include a plurality of resistors, and applies a gamma voltage to one of the positive and negative resistor strings in response to a polarity selection signal, thereby generating and outputting a positive grayscale voltage and a negative grayscale voltage.
