Abstract

An electrophoresis display apparatus is provided comprising a display panel comprising data lines and gate lines crossing the data lines, a data driving circuit generating data voltages selected among a positive voltage, a negative voltage, and a ground voltage during an image update period and supplying the data voltages to the data lines, a gate driving circuit supplying gate pulses to the gate lines in synchronization with the data voltages during the image update period, and a control logic circuit blocking an output of the data driving circuit based on a variation in one of the positive voltage and a logic power voltage immediately after the image update period, wherein the logic power voltage is lower than the positive voltage and higher than the ground voltage and wherein the ground voltage is lower than the logic power voltage and higher than the negative voltage.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2010-0111100 filed on Nov. 09, 2010, the entire contents of which are hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0002] Embodiments of the present invention relate to an electrophoretic display device and a method for controlling a power source of the electrophoretic display device. Background technique [0003] When subjected to the conditions of an electric field, a charged material begins to move molecules according to their size and shape and charge. This phenomenon is called "electrophoresis". Recently, display devices are being developed using electrophoresis, and such display devices are attracting attention as a substitute for existing paper media or conventional display elements. [0004] Inventions related to electrophoretic displays are disclosed in US Patent Nos. 7,012,6000 and 7,119,772. An electrophoretic display device includes...
