Liquid crystal display backplane layouts and addressing for non-standard subpixel arrangements

A method for creating a liquid crystal display, said display comprising a display panel substantially comprising a plurality of a subpixel repeating group tiled across said display panel in a regular pattern;

• said subpixel repeating group comprising an even number of subpixels in a first direction, the method comprising:
• choosing a subpixel repeating group such that the subpixel repeating group comprises two rows of an even number of subpixels wherein each row of subpixels comprises at least two same-colored subpixels;
• choosing a dot inversion scheme to drive the subpixels;
• and
• for each subpixel in said repeating group, placing an associated thin film transistor in a quadrant of said subpixel;
• and wherein the associated TFT of each of said same-colored subpixels in both rows is placed in a quadrant of its respective subpixel so as to connect all same-colored subpixels in both rows to a common row line such that said dot inversion scheme, when effected on said subpixels, causes same colored subpixels to be driven by alternating polarity signals.

• a quadrant location of said associated TFT within said subpixel determining to which row line and to which column line a subpixel is connected;
• said quadrant locations of all TFTs on said display panel implementing a row-and-column-line connection pattern and wherein the associated TFT of each of said same-colored subpixels in both rows is formed in a quadrant of its respective subpixel so as to connect all same-colored subpixels in both rows to a common row line;
• and
• driver circuitry configured to send image signals and polarity signals to said subpixels along one of a row line and column line;
• said polarity signals implementing a polarity scheme which, when implemented in conjunction with said row-and-column-line connection pattern of said TFTs, reduces image artifacts on said display panel.
