Patent Images
1. A display device, comprising an array of rows and columns of pixels, the array comprising:
- a commonly controlled plurality of first electrodes for supplying a first common drive signal to each pixel of the array, each first electrode extending through or alongside a row of pixels for supplying the common drive signal to the pixels of the row, wherein the plurality of first electrodes are connected together to supply said common drive signal;
a commonly controlled plurality of second electrodes for supplying a second common drive signal different from the first common drive signal to each pixel of the array, each second electrode extending through or alongside a row of pixels for supplying the second common drive signal to the pixels of the row, wherein the plurality of second electrodes are connected together to supply said second common drive signal; and
a plurality of pixel addressing electrodes for supplying data to the pixels to control optical appearances of the pixels; and
wherein at least the first and second pluralities of electrodes are arranged on a common substrate.

Abstract
The display device (10) comprises an array of rows and columns of pixels. The display device further comprises a plurality of commonly controlled first electrodes (FE) for supplying a common signal (DS1) to each pixel (13), a plurality of commonly controlled second electrodes (SE) for supplying a further common signal (DS2) to each pixel, and a plurality of pixel addressing electrodes (AC1, AC2, AC3, AC4) for addressing the individual pixels. At least the plurality of first electrodes and the plurality of second electrodes are routed parallel to one another, such that crossovers between the commonly controlled electrodes are eliminated.
