    Abstract: A display panel (320) of an electronic matrix display (205) can have a set of pixel elements (245), a matrix of gate lines (215) and source lines (220), and a set of switches (235). Pixel elements (245) can be of at least three different colors arranged in a repeating pattern to form a matrix of horizontal and vertical rows. In each horizontal row, each pixel element (245) except those on the ends of the horizontal row has two neighboring pixel elements that are a different color than the pixel element (245) and that are a different color than each other. Each unique intersection point of the gate lines (215) and source lines (220) of the matrix can be hardwired to a set of more than one of the pixel elements (245) of the same color.
