Abstract

The invention discloses an electrophoretic display device comprising an electrophoretic display panel and a driving circuit, wherein the electrophoretic display panel comprises a plurality of pixel units, and the driving circuit is used for supplying driving signals to the pixel units and is integrated into the electrophoretic display panel by a manufacturing technology of a thin film transistor. Because the driving circuit of the electrophoretic display device is integrated into the electrophoretic display panel, no additional drive chips need to be purchased, thus the manufacturing processes is simplified and the production cost is reduced. The electrophoretic display device can be as lighter and thinner as possible and can be produced in bath.

Description

technical field [0001] The invention relates to the field of electrophoretic display, in particular to an electrophoretic display device. Background technique [0002] At present, the so-called electrophoretic phenomenon, in which charged particles dispersed in a liquid swim due to an external electric field, is well known, and an electrophoretic display device using the electrophoretic phenomenon has been developed. The electrophoretic display device combines ordinary paper and electronic display. The advantages of the device are both readability and portability, so electrophoretic display devices have been confirmed to replace traditional paper media. [0003] In general, an electrophoretic display device includes two substrates, one of which is transparent, and the other substrate is provided with a plurality of data lines and a plurality of gate lines intersecting each other, and the intersections of the gate lines and the data lines define A pixel unit. Wherein, the p...
