    Abstract: A method of driving a display panel includes generating a high pixel gamma voltage and a low pixel gamma voltage. At least one of the high pixel gamma voltage and the low pixel gamma voltage includes a positive gamma voltage and a negative gamma voltage having different values. The positive gamma voltage is a difference between a first gamma voltage higher than a common voltage and the common voltage. The negative gamma voltage is a difference between the common voltage and a second gamma voltage lower than the common voltage. A high pixel data voltage is generated based on the high pixel gamma voltage and the high pixel data voltage output to a high pixel. A low pixel data voltage is generated based on the low pixel gamma voltage and the low pixel data voltage is output to a low pixel.
