Problems solved by technology

[0005] However, when the assembler deliberately reserves the two protruding regions 121 of the electrophoretic display panel 12, the part of the material of the electrophoretic display panel between the two protruding regions 121 may form redundant materials that cannot be reused.
In this way, not only the cutting utilization rate will drop sharply, but also the cost of materials will increase.
In addition, as the size of electrophoretic display devices (such as e-books) is shrinking day by day, the proportion of wasted materials is higher in comparison

Abstract

The invention discloses an electrophoretic display device and a manufacture method thereof. The electrophoretic display device comprises a drive base plate, an electrophoretic display panel, a control unit and a conducting medium, wherein the drive base plate comprises a plurality of pixel electrodes, and the pixel electrodes are arranged in an effective display area of the drive base plate; the electrophoretic display panel is arranged on the drive base plate and defined with a peripheral area; the control unit is arranged on the drive base plate and positioned at the opposite side of the peripheral area so that the effective display area is arranged between the control unit and the peripheral area; and the conducting medium is positioned in the peripheral area and electrically connected with the control unit and the electrophoretic display panel. The structure can omit two convex areas and an electrophoretic display panel material between the two convex areas of the traditional electrophoretic display panel, not only improves the cutting utilization ratio of the large-size electrophoretic display panel material but also reduces the material cost.

Description

technical field [0001] The present invention relates to a display device, in particular to an electrophoretic display device and a manufacturing method thereof. Background technique [0002] The volume and weight of the existing flat panel displays are not as good as the advantages of convenient portability and convenient reading brought by paper printed matter. Therefore, an electrophoretic display device (Electrophoretic Display Apparatus, EPD Apparatus) using an electrophoretic material is born accordingly. The electrophoretic display device not only maintains the portability and readability of paper, but also has the effectiveness and environmental protection of electronic products for data processing. [0003] As shown in FIG. 1 , FIG. 1 is a schematic diagram of a conventional electrophoretic display device. The conventional electrophoretic display device 10 includes a driving substrate 11 , an electrophoretic display panel 12 and a control unit 13 . Both the electr...
