Claim Text:
1. A display device, comprising: a display panel including a plurality of pixels, wherein each pixel includes first and second sub-pixels; a gamma reference voltage generator configured to generate at least one first gamma reference voltage each having a high gamma value greater than a reference gamma value, and at least one second gamma reference voltage each having a low gamma value less than the reference gamma value; a data driver configured to i) generate a data voltage based at least in part on one or more of the first and second gamma reference voltages and ii) provide the data voltage to the first and second sub-pixels; and a driving controller configured to determine a gamma value and a data voltage output pattern according to a driving mechanism of the display panel, wherein the data driver includes a voltage divider configured to generate a plurality of gray scale voltages based at least in part on a voltage division of the first and second gamma reference voltages, wherein the voltage divider is configured to divide the first and second gamma reference voltages into positive and negative gamma reference voltages, and wherein the gray scale voltages include i) a positive first gray scale voltage generated based on a positive first gamma reference voltage, ii) a negative second gray scale voltage generated based on a negative first gamma reference voltage, iii) a positive third gray scale voltage generated based on a positive second gamma reference voltage, and iv) a negative fourth gray scale voltage generated based on a negative second gamma reference voltage.
