Japanese Patent JP2003520356
Kind Code:

Abstract:
An active matrix electroluminescent display device (2) comprises an array of display pixels (4) arranged in rows (6) and columns (8). Each pixel (4) comprises a current-driven electroluminescent display element (10). Each row (6) of pixels (4) shares a common line (20), currents through the display elements (10) of a row (6) of pixels passing along the common line (20). The width of each common line (20) tapers from one end (20a) to the other (20b), the common line (20) being coupled to row driver circuitry at the wider end (20a). The resistance of the common lines is thus reduced at the end of the common line near to the row driver circuitry, where the current flowing is derived from all pixels within the row. The invention thereby reduces voltage drops along the common line, which contribute to cross-talk between pixels within a row.
