Abstract

The invention discloses an electrophoretic display device and a drive method thereof. The electrophoretic display device comprises a plurality of data lines, a plurality of gate lines and a plurality of pixel units, wherein the data lines and the gate lines are mutually intersected; the pixel units are positioned at the intersections of the gate lines and the data lines; and each pixel unit comprises a switch element, a first voltage line, a second voltage line, a voltage selecting unit and a pixel electrode, wherein the voltage selecting unit is respectively connected with the switch element, the first voltage line and the second voltage line, and the pixel electrode is connected with the voltage selecting unit. The electrophoretic display device disclosed by the invention is not required to be equipped with a data driven circuit with a larger voltage driving range, thereby lowering the production cost, and reducing the leakage current.

Description

technical field [0001] The invention relates to the field of electrophoretic display, in particular to an electrophoretic display and a driving method thereof. Background technique [0002] At present, the phenomenon of swimming of charged particles dispersed in a liquid due to an applied electric field, that is, the so-called electrophoretic phenomenon, has been well known, and an electrophoretic display utilizing the electrophoretic phenomenon has been developed, which combines the advantages of ordinary paper and electronic displays. Advantages, it is both readable and portable, and has the characteristics of wide viewing angle and flexibility, so electrophoretic displays have been confirmed to replace traditional paper media. [0003] Generally, an existing electrophoretic display includes: a first substrate, a second substrate, and an electronic ink layer arranged between the first substrate and the second substrate. Wherein, a plurality of data lines and a plurality o...
