Electrophoresis display panel and manufacturing method thereof

Abstract

The embodiment of the application discloses an electrophoresis display panel and a manufacturing method of the electrophoresis display panel. The electrophoresis display panel comprises a substrate, a first metal layer located on the substrate, a second metal layer located on the first metal layer, a third metal layer located between the first metal layer and the second metal layer, and a plurality of metal change lines, wherein the substrate comprises a display area and a non-display area, a first capacitance plate is arranged on the first metal layer, a plurality of shading areas are arranged on the second metal layer, a second capacitance plate is arranged on the third metal layer, and the metal change lines extends along the section direction, are arranged along the first direction and are used for transmitting a data signal to a data line, wherein at least one of the metal change lines is located in the display area and is arranged on the second metal layer. Through adoption of the implementation mode, occupying the first metal layer and / or the third metal layer by the metal change line is reduced, so that the capacitance between the first capacitance plate and the second capacitance plate is increased to meet the display requirement.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an electrophoretic display panel and a manufacturing method. Background technique [0002] At present, the basic principle of electrophoretic display is usually to control the moving position of electrophoretic particles through the electric field, and control the reflection of light through the moving position, so as to achieve the desired brightness. The structure of the existing electrophoretic display panel is generally to form an electrophoretic film between the pixel electrode and the common electrode. In this way, DC voltage signals are respectively provided to the pixel electrode and the common electrode, and an electric field can be formed between the two, thereby realizing picture display. The specific structure of the electrophoretic display surface can be found in figure 1 , which shows a schematic structural view of an existing electrophoretic display pa...

Problems solved by technology

[0005] However, since the scanning line 13, the metal replacement line 14 and the capacitor plate are arranged on the same film layer, this will affect the area of ​​the capacitor plate in the film layer, thereby reducing the electric charge between the two capacitor plates. capacity, which in turn cannot meet the design requirements during the hold phase
