Flexible display
View Patent ↗A display is disclosed, which can be fabricated without a high-temperature process, and also realize color images, the display including a reflective electrode formed on a flexible substrate; a transparent insulation layer having a predetermined color formed on a surface of the flexible substrate including the reflective electrode; an opposite substrate formed in opposition to the flexible substrate; an opposite electrode and a black matrix formed on an inner surface of the opposite substrate; and an electrolytic layer and a nonelectrolytic layer formed between the flexible substrate and the opposite substrate, where the electrolytic layer is transparent, and the nonelectrolytic layer is nontransparent.
1. A display comprising:
a reflective electrode formed of a metal material which can reflect light on a first substrate;
a transparent insulation layer having a predetermined color formed on the first substrate including the reflective electrode;
a second substrate disposed in opposition to the first substrate;
an electrode formed on a surface of the second substrate and disposed facing the first substrate;
a black matrix formed on the surface of the second substrate adjacent to the electrode, and
an electrolytic layer and a nonelectrolytic layer formed between the first substrate and the second substrate, wherein the electrolytic layer is transparent, and the nonelectrolytic layer is nontransparent.
2. The display of claim 1 , wherein the electrolytic layer is formed of a water solution.
3. The display of claim 1 , wherein the nonelectrolytic layer is formed of oil.
4. The display of claim 1 , wherein the electrode is formed of a transparent conductive material.
5. The display of claim 1 , wherein the transparent insulation layer is formed of a hydrophobic material.
6. The display of claim 1 , wherein the transparent insulation layer has a single color pigment and is coated on an entire surface of the first substrate.
7. The display of claim 1 , wherein the transparent insulation layer has different color pigments and is coated onto the first substrate.
8. The display of claim 7 , wherein the transparent insulation layer having the red (R), green (G) or blue (B) colors for each pixel is coated onto the first substrate.
9. The display of claim 1 , wherein the transparent insulation layer includes a pigment.
10. The display of claim 1 , wherein the second substrate is transparent and flexible.
11. The display of claim 1 , wherein the portion of the second substrate provided with the reflective electrode corresponds to an image-display area, and the portion of the second substrate provided with the black matrix corresponds to a non-display area.
12. The display of claim 1 , wherein the first substrate includes a gate and a data line formed perpendicularly to each other to define a pixel, and a thin film transistor formed adjacent to a crossing of the gate line and the data line and connected to the reflective electrode.
13. The display according to claim 12 , wherein the first electrode is formed inside each pixel of the first substrate.
14. The display according to claim 1 , wherein the first substrate is flexible substrate.
15. The display according to claim 1 , wherein the second electrode is formed on the entire surface of the second substrate.
16. The flexible display according to claim 1 , wherein the transparent electrolyte layer is moved to a first region and the opaque non-electrolyte layer is moved to a region between the first electrode and the black matrix by an electric field formed between the first and second electrodes.
