Problems solved by technology

[0003] 1) The electrochromic layer is often formed by injecting a liquid electrochromic material into the gap, which can easily cause the electrode above the gap to collapse due to pressure difference, and its packaging is difficult, and it is prone to liquid leakage, which seriously affects the electrochromic layer. The quality of the chromic display panel;
[0004] 2) It is often impossible to display pure black, or the device that displays pure black has a complex structure and slow response speed

Description

technical field [0001] The invention relates to an electrochromic display panel and electronic paper, belonging to the field of display technology. 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 external electric field, and the appearance is manifested as color and transparency. reversible changes. Materials with electrochromic properties are called electrochromic materials, and devices made of electrochromic materials are called electrochromic devices. Electrochromic materials are one of the hotspots in material science research in recent years. Electrochromic materials are an important part of electrochromic devices, which dominate the electrochromic performance of devices. According to the structural properties of materials, electrochromic materials can be divided into anodic electroch...
