Patent ID: 7486261

Claim:
An electro-luminescence display device, comprising: an electro-luminescence display panel having pixel cells arranged at intersections of a plurality of data electrode lines and a plurality of scan electrode lines, the scan electrode lines being in a unit of two electrode lines, and each of the pixel cells along a same row being connected to one scan electrode line of a corresponding scan electrode line unit in a zigzag manner; a multiplexer for selectively applying data signals to at least two of the data electrode lines during a half of one horizontal period; a data driving circuit for applying the data signals to the multiplexer; and a controller for applying at least first and second selection signals to the multiplexer, wherein the number of the data electrode lines is m, m being an integer, and the data driving circuit includes m/2 output channels connecting to the multiplexer, wherein the multiplexer includes at least a first switching device and a second switching device, the first switching device being connected to the output channels and the data electrode lines connecting to the pixel cells connected to odd-numbered ones of the scan electrode lines, and the second switching device being connected to the output channels and the data electrode lines connecting to the pixel cells connected to even-numbered ones of the scan electrode lines, wherein the pixel cells are in a unit of k number of pixel cells, k being an integer more than one, and the pixel cell units along a same row are connected to one of the odd-numbered and even-numbered scan electrode lines of the corresponding scan electrode line unit in a zigzag manner, and wherein the first switching device connects the output channels to the data electrode lines connecting to the pixel cells connected to the odd-numbered scan electrode lines in response to the first selection signal from the controller, and the second switching device connects the output channels to the data electrode lines connecting to the pixel cells connected to the even-numbered scan electrode lines in response to the second selection signal from the controller.
