Electrode structure

Abstract

An electrode structure is provided. The electrode structure contains a first auxiliary electrode and a second auxiliary electrode, a first edge electrode and a second edge electrode disposed between the first auxiliary electrode and the second auxiliary electrode, wherein the first edge electrode forming an electrode pair with the first auxiliary electrode and having a same polarity as that of the first auxiliary electrode and the second edge electrode forming an electrode pair with the second auxiliary electrode and having a same polarity as that of the second auxiliary electrode, and at least one middle electrode disposed between the first edge electrode and the second edge electrode. The electrode structure respectively enhance an interaction between the first edge electrode and the second edge electrode and a neighboring electrode by means of the first auxiliary electrode and the second auxiliary electrode. Alternatively, the width of the edge electrode increase to be 1.5 to 4 times of its original value in order to increase the current density on the edge electrode and to increase the brightness of the edge discharging zone so that the brightness difference between the middle zone and the edge zone is not great.
