Abstract

A mobile terminal includes a window having an opaque region, which includes a transparent substrate, a first layer formed on one surface of the substrate and having a color, and a second layer formed on one surface of the first layer and configured to reflect light incoming through the first layer and light outgoing from the inside.

Claims

1. A mobile terminal comprising:

a body to contain electronic components of the mobile terminal;

a display provided on the body to provide images; and

a window provided on the display, the window including a transparent region and an opaque region, the opaque region to obscure a portion of the display from a viewer of the display,

wherein the opaque region of the window comprises;

a transparent substrate,

a first layer formed on a surface of the substrate, the first layer having a single color, and

a second layer formed on a surface of the first layer, the second layer of the opaque region provided between the first layer and the display, the second layer to reflect incoming light received through the first layer in a direction away from the display, and the second layer to reflect light received from the display in a direction away from the first layer.

2. The mobile terminal of claim 1, wherein the second layer of the opaque region includes a first surface that faces the first layer and a second surface that faces the display, the first surface of the second layer reflects the incoming light received from the first layer in the direction away from the display, and the second surface of the second layer reflects the light received from the display in the direction away from the first layer.

3. The mobile terminal of claim 1, wherein the second layer is formed of a non-conductive material.

4. The mobile terminal of claim 1, wherein the second layer is formed of one of indium, tin, or a combination of silicon oxide and titanium oxide.

5. The mobile terminal of claim 1, wherein the second layer is formed of a material with a high luminance.

6. The mobile terminal of claim 1, wherein the second layer is formed by one of thermal resistance evaporation, sputtering or Non-Conductive Vacuum Metalizing (NCVM).

7. The mobile terminal of claim 1, wherein an area of the second layer is at least as wide as an area of the first layer.

8. The mobile terminal of claim 1, wherein the first layer includes a first sub-layer and a second sub-layer, the first sub-layer of the first layer provided between the substrate and the second sub-layer, the first sub-layer having a greater width than the second sub-layer.

9. The mobile terminal of claim 1, wherein the first layer includes a hole with a preset shape.

10. The mobile terminal of claim 1, wherein the opaque region of the window further comprises a third layer formed under the second layer, the third layer to adsorb light from the display.

11. The mobile terminal of claim 10, wherein the third layer is formed with a gray color or a black color.

12. The mobile terminal of claim 10, wherein the opaque region of the window further comprises a fourth layer and a fifth layer, the fourth layer provided between the third layer and the fifth layer.

13. The mobile terminal of claim 12, wherein the fourth layer adheres the substrate, the first layer, the second layer and the third layer onto the fifth layer.

14. The mobile terminal of claim 13, wherein the fourth layer comprises an optical adhesive film.

15. The mobile terminal of claim 13, wherein the fifth layer detects a touch input.

16. The mobile terminal of claim 1, wherein the opaque region is provided around a circumference of the transparent region.

17. A mobile terminal comprising:

a wireless communication unit to provide wireless communication;

a display to display images;

a touch window on the display to receive touch inputs; and

a body to support the wireless communication unit, the display and the touch window, wherein the touch window includes a transparent region and an opaque region,

wherein the opaque region of the window includes;

a transparent substrate,

a first layer formed under the substrate, and

a second layer formed under the first layer such that the first layer is provided between the second layer and the substrate, the second layer including a first surface to face the first layer and a second surface to face away from the first layer, the first surface of the first layer to reflect external light away from the display, and the second surface of the second layer to reflect internal light away from the first layer.

18. The mobile terminal of claim 17, wherein the second layer is formed of a non-conductive material.

19. The mobile terminal of claim 17, wherein the second layer is formed of one of indium, tin, or a combination of silicon oxide and titanium oxide.

20. The mobile terminal of claim 17, wherein the first layer has a first sub-layer and a second sub-layer, the first sub-layer provided between the substrate and the second sub-layer, the first sub-layer having a greater width than the second sub-layer.

21. The mobile terminal of claim 17, wherein the opaque region of the window further comprises a third layer formed under the second layer, the third layer to adsorb light from the display.

22. The mobile terminal of claim 21, wherein the opaque region of the window further comprises a fourth layer and a fifth layer, the fourth layer provided between the third layer and the fifth layer, wherein the fourth layer adheres the substrate, the first layer, the second layer and the third layer onto the fifth layer, and the fifth layer detects a touch input.

23. The mobile terminal of claim 22, wherein the fourth layer comprises an optical adhesive film.

24. The mobile terminal of claim 17, wherein a width of the first layer is less than a width of the substrate, and a width of the second layer is less than a width of the first layer.

25. The mobile terminal of claim 17, wherein the opaque region is provided around a circumference of the transparent region.
