Abstract

An electrophoresis display and a driving method thereof are disclosed. The present invention relates to an electrophoresis display electrophoresis display that is able to reduce the size of circuits for driving a display panel by decreasing driving voltages required to display images and the unit cost of the product. An electrophoresis display includes a display panel comprising a plurality of pixel cells to display an image, a data driving unit supplying a pixel voltage to a plurality of data lines provided in the display panel, a common voltage generating unit generating a common voltage swinging to reverse electric potential and supplying the common voltage to a common electrode of the display panel, and a timing control unit generating a data control signal and a common voltage control signal and controlling a driving timing of the data driving unit and the common voltage generating unit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2008-0128470 filed on December 17, 2008, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an electrophoretic display, and more particularly, to an electrophoretic display capable of reducing the size of a circuit for driving a display panel and reducing the unit cost of a product by reducing the driving voltage required to display an image. Background technique [0004] If a charged material is placed in a DC electric field, the charged material will move according to the charge and the size and shape of the molecules. This movement is called electrophoresis, and is also known as the phenomenon of separating materials according to their movement. [0005] Currently, a display using this electrophoretic phenomenon is attracting attention as an alternative to paper. Displays...
