  • Data driving circuit and display device using the same
    Patent number: 11423821
    Abstract: A data driving circuit includes a first voltage divider circuit configured to output a gamma compensation voltage for a first color, a second voltage divider circuit configured to output a gamma compensation voltage for a second color, a third voltage divider circuit configured to output a gamma compensation voltage for a third color, a first digital-to-analog converter (DAC) configured to convert input data for the first color using the gamma compensation voltage for the first color to output a data voltage of a first channel, a second DAC configured to convert input data for the second color using the gamma compensation voltage for the second color to output a data voltage of a second channel, and a third DAC configured to convert input data for the third color using the gamma compensation voltage for the third color to output a data voltage of a third channel.
