Abstract

A display device includes a display panel and a converter formed on a front surface of the display panel. The converter performs conversion between a 2-dimensional image and a 3-dimensional image. The converter includes a plurality of protrusion electrodes formed on a first substrate. A plate electrode is positioned on a second substrate facing the first substrate. A transparent medium is positioned between the protrusion electrodes and the plate electrode. A plurality of conductive particles is positioned in the transparent medium.

Claims (34)

1. A display device, comprising:

a display panel; and

a converter formed on a front surface of the display panel, the converter configured to perform conversion between a 2-dimensional image and a 3-dimensional image,

wherein the converter comprises:

a plurality of protrusion electrodes formed on a first substrate;

a plate electrode positioned on a second substrate facing the first substrate;

a transparent medium positioned between the protrusion electrodes and the plate electrode; and

a plurality of conductive particles positioned in the transparent medium.

2. The display device of claim 1 , wherein the converter further comprises a barrier and a transmissive region that are formed by applying voltages to the protrusion electrodes and the plate electrode.

3. The display device of claim 2 , wherein at least one of the plate electrode and the plurality of protrusion electrodes is formed of a transparent conductive material.

4. The display device of claim 2 , wherein the protrusion electrodes and the plate electrode are separated from each other by a predetermined interval.

5. The display device of claim 4 , wherein the plurality of protrusion electrodes extend in a direction in which the barrier extends.

6. The display device of claim 5 , wherein two adjacent protrusion electrodes of the protrusion electrodes are spaced apart from each other by a predetermined interval.

7. The display device of claim 1 , wherein the plurality of conductive particles is black.

8. The display device of claim 1 , wherein the display panel is configured to alternately display a left-eye image and a right-eye image when displaying the 3-dimensional image.

9. The display device of claim 8 , wherein the display panel is one of flat display panels including an organic light emitting display panel, a liquid crystal display panel, a plasma display panel (PDP), an electrophoretic display panel, and an electrowetting display panel.

10. A converter configured to perform conversion between a 2-dimensional image and a 3-dimensional image, the converter comprising:

a plurality of protrusion electrodes formed on a first substrate;

a plate electrode positioned on a second substrate facing the first substrate;

a transparent medium positioned between the protrusion electrodes and the plate electrode; and

a plurality of conductive particles positioned in the transparent medium.

11. The converter of claim 10 , wherein the converter further comprises a barrier and a transmissive region that are formed by applying voltages to the protrusion electrodes and the plate electrode.

12. The converter of claim 11 , wherein at least one of the plate electrode and the plurality of protrusion electrodes is formed of a transparent conductive material.

13. The converter of claim 12 , wherein the protrusion electrodes and the plate electrode are separated from each other by a predetermined interval.

14. The converter of claim 13 , wherein the plurality of protrusion electrodes extend in a direction in which the barrier extends.

15. The converter of claim 14 , wherein two adjacent protrusion electrodes of the plurality of neighboring protrusion electrodes are spaced apart from each other by a predetermined interval.

16. The converter of claim 10 , wherein a plurality of conductive particles is black.

17. A display, comprising:

a display panel; and

a converter disposed on the display panel, the converter comprising:

a first substrate having a plate electrode;

a second substrate having a plurality of protrusion electrodes spaced apart from each other by a predetermined distance;

a transparent medium interposed between the first substrate and the second substrate, the transparent medium including a plurality of conductive particles, wherein the plurality of conductive particles are configured to interact with the plurality of protrusion electrodes upon application of a voltage between the plate electrode and the plurality of protrusion electrodes to form a barrier and a transmissive region along a direction of the converter.

18. The display of claim 17 , wherein when the display panel displays a two-dimensional image, the barrier is not formed.
