| 1. A method of generating source line voltages in a display device, comprising:
receiving by a source driver gray scale data for a first sub-pixel of a pixel having the first sub-pixel and a second sub-pixel;
wherein the source driver receives the gray scale data for the first sub-pixel during a one line time period while the source
driver does not receive any gray scale information for the second sub-pixel during any portion of the one line time period;
generating by the source driver a first source line voltage for the first sub-pixel from the gray scale data during a first
portion of said one line time period; and
generating by the source driver a second source line voltage for the second sub-pixel of the pixel from the gray scale data
of the first sub-pixel during a second portion of said one line time period such that the second source line voltage of the
second sub-pixel becomes determined at the source driver during the second portion of said one line time period,
wherein said one line time period is for a time length when a polarity signal remains constant during said time length,
and wherein the polarity signal alternates between high and low logic states after each of said time length.
