Abstract

A display includes a display medium layer and a dielectric layer disposed at a side of the display medium layer. The composition of the dielectric layer includes at least a humectant for decreasing the electric resistivity of the dielectric layer and stabilizing the electric performance of the display.

Claims (13)

1. A display, comprising:

a display medium layer; and

a dielectric layer disposed at a side of the display medium layer, and a composition of the dielectric layer comprises at least a humectant, wherein the humectant comprises chemical compounds that are capable of forming hydrogen bonds with water and includes small molecules with high polar group density, and the small molecules are at least one of phytantriol, sorbitol, fructose, sodium-2-pyrrolidone-5-carboxylate, hyaluronic acid, hydroxylethyl urea, hydroxypropyl bis-hydroxyethyldimonium chloride, and polyquaternium-71 or a combination of the above compounds.

2. The display of claim 1 , wherein molecular weight of each of the small molecule is less than about 1000.

3. The display of claim 2 , wherein the molecular weight of each of the small molecule has a range from about 50 to about 200.

4. The display of claim 1 , wherein the humectant comprises sugar polyol.

5. The display of claim 4 , wherein the sugar polyol comprises at least one of polymer polyol and glycerol.

6. The display of claim 1 , wherein the dielectric layer comprises at least one of a sealing layer and an adhesive layer.

7. The display of claim 6 , further comprising a substrate disposed at a side of the display medium layer, and the sealing layer is disposed at a side of the display medium layer opposite to the substrate.

8. The display of claim 6 , further comprising a substrate disposed at a side of the display medium layer, and the adhesive layer is disposed at a side of the display medium layer opposite to the substrate.

9. The display of claim 1 , wherein the display is an electrophoresis display (EPD), and the display medium layer comprises an electrophoretic medium layer.

10. The display of claim 9 , wherein the display further comprises a plurality micro-cup structures disposed within the display medium layer, and a composition of the micro-cup structures is dielectric and includes a humectant.

11. The display of claim 1 , wherein the dielectric layer further comprises at least a polymer.
