preparation example Construction

[0074] see Figure 4 , a method for preparing an electrodeposited display component in one embodiment, comprising the following steps:

[0075] S110, preparing a first electrode film.

[0076] In one of the embodiments, the step of preparing the first electrode film is as follows: plating a transparent ITO conductive layer on the first substrate, etching the ITO conductive layer so that the electrode pattern appears, and etching the ITO conductive layer Form the first electrode wiring area after etching; plate a transparent first insulating layer on the ITO conductive layer, etch the first insulating layer to expose the electrode pattern of the ITO conductive layer, and make the first insulating layer cover the first electrode wiring area. The prepared first electrode film is used for a partially erasable segment code display component.

[0077] In another embodiment, the step of preparing the first electrode film is as follows: plating a transparent ITO conductive layer on...

Embodiment 1

[0096] (1) Preparation of the first electrode film: Take a glass substrate with a thickness of 0.5 mm, plate it with an ITO conductive film to obtain an ITO glass with a square resistance of 10 ohms, wash with water, wash with acetone, and dry it before use.

[0097] (2) Preparation of the second electrode film: get a transparent glass with a thickness of 0.5mm slightly larger than the area of ​​the first electrode film, and form a layer of silver conductive layer with a thickness of about 2 μm by magnetron sputtering. Then form a bismuth layer with a thickness of about 5 μm on the silver conductive layer, etch the silver conductive layer and the bismuth layer with 10% nitric acid to make it show electrode patterns; then coat a layer of bismuth with a thickness of about 10 μm. The silicon oxide insulating layer is etched to expose the electrode pattern area; then a bismuth layer is electroplated on the etched area of ​​the silicon dioxide insulating layer until the thickness is...

Embodiment 2

[0105] (1) Preparation of the first electrode film: Take a glass substrate with a thickness of 0.5mm, plate it with an ITO conductive film to obtain an ITO glass with a square resistance of 10 ohms, wash with water, acetone and water, and coat a layer of photoresist , after exposure, etch the electrode pattern with 10% nitric acid, then deposit a silicon dioxide insulating layer with a thickness of 0.2 μm by chemical vapor deposition, and then etch the silicon dioxide insulating layer to display the electrode pattern .

[0106] (2) Preparation of the second electrode film: get a transparent glass with a thickness of 0.5mm slightly larger than the area of ​​the first electrode film, and form a layer of silver conductive layer with a thickness of about 2 μm by magnetron sputtering. Then form a bismuth layer with a thickness of about 10 μm on the silver conductive layer, etch the silver conductive layer and the bismuth layer with 10% nitric acid to make it show electrode patterns...

Abstract

The invention relates to an electro-deposition display component and a preparation method thereof. The electro-deposition display component comprises a first electrode membrane, a second electrode membrane and a sealing frame, wherein the first electrode membrane and the second electrode membrane are arranged at interval, the sealing frame, the first electrode membrane and the second electrode membrane form an accommodating cavity in an enclosed manner, and the accommodating cavity is filled with electrolyte; the electrolyte comprises, by mass, 100 parts of organic solvent and 1-20 parts of bismuth salt. The electro-deposition display component has the advantages that the electrolyte uses the bismuth salt as the electrolyte to replace traditional silver salt, the bismuth salt is low in cost, good in stability under an illumination condition and low in oxidation potential and cannot be easily reduced and blackened as compared with the silver salt, needed voltage during the erasing of images on the electro-deposition display component is low, and the electro-deposition display component instability situation caused by the fact that anions in the electrolyte of the electro-deposition display component have anodic oxidation reaction with an organic solvent due to high voltage is reduced.

Description

technical field [0001] The invention relates to the technical field of bistable reflective displays, in particular to an electrodeposited display component and a preparation method thereof. Background technique [0002] Compared with the currently widely used LCD, LED and OLED displays, the bistable reflective display has the unique advantages of no light, low power consumption, and the image does not disappear when the power is turned off. It is especially suitable for outdoor display and display with low refresh rate Fields, such as instrumentation, household appliances and electronic reading, etc. Currently disclosed bistable reflective display technologies include cholesteric liquid crystal display technology, electronic ink display technology, electrochromic display technology and electrodeposition display technology. Among them, the cholesteric liquid crystal display technology has low contrast and poor white background display effect, and has basically not been appli...
