Abstract
An electrode of an E-paper panel having a lattice structure, wherein an electric field concentrated on edge regions of the electrode is dispersed, and thus while driving a cell, charged particles are uniformly distributed over an entire region of the cell, thereby improving display performance. For this purpose, the E-paper panel includes a driving electrode integrally driven by a driving signal for driving a cell, a portion of the driving electrode corresponding to the cell region being partially removed according to a particular pattern.
Claims20
