Problems solved by technology

[0005] However, it can be seen from the above display principles that since the R pixel unit 11, the G pixel unit 12 and the B pixel unit 13 are in a transparent state when they are not displayed, the ECD can only switch between a transparent state and a colored state, but cannot Displays black, resulting in very low contrast in the ECD

Abstract

The embodiment of the invention provides an electrophoresis display device, display equipment and a display method, and relates to the technical field of display. Black can be displayed on an electro chromism device (ECD), and therefore the contrast ratio of the ECD is increased. The electrophoresis display device comprises a first substrate and a second substrate which are oppositely arranged, N sealed electrophoresis units are distributed between the first substrate and the second substrate in an array mode, and the N is an integer larger than one, wherein a first wall-shaped electrode and a second wall-shaped electrode are arranged on the two opposite sides of each electrophoresis unit; the electrophoresis units are filled with transparent electrophoretic media, and multiple black charged particles are arranged in the electrophoretic media. The electrophoresis display device can be applied to the image display process of the ECD.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an electrophoretic display device, a display device and a display method. Background technique [0002] Electrochromism (EC) refers to the phenomenon that the optical properties of materials (reflectivity, transmittance, absorptivity, etc.) undergo stable and reversible color changes under the action of an applied electric field. [0003] Materials with electrochromic properties are called electrochromic materials, that is, EC materials, and devices made of EC materials are called electrochromic displays (ElectroChromismDevice, ECD). Among them, EC materials can make light through oxidation or reduction reactions. The reversible change of the transmission or reflection of the material can realize the display. [0004] Specifically, such as figure 1 As shown, it is a schematic structural diagram of the current ECD, wherein the ECD includes the upper and lower electrode ...
