ABSTRACT:
A display device includes a data voltage generating circuit supplied with a data signal and generating a data voltage. The data voltage generating circuit includes a gamma reference voltage generator generating first and second gamma reference voltages and a gray level voltage generator including a plurality of gray level voltage dividers generating a plurality of 2kgray level voltages. The gray level voltage dividers use the first and second gamma reference voltages, wherein one of the plurality of gray level voltage dividers is selected and supplied with the first and second gamma reference voltage. The data voltage is one of the selected 2kgray level voltages corresponding a gray level of a data signal. A display panel displays images using the data voltage.
