Abstract

A touch screen and machine-implemented method for providing a touch screen panel are provided. The touch screen is formed on a panel including a display area and a bezel area that at least partially surrounds the display area. The touch screen includes a first pattern of conducting material arranged on the display area of the panel and a second pattern of conducting material arranged on the bezel area of the panel, where the first pattern of conducting material is transparent.

Claims

1. A touch screen comprising:

a panel comprising a display area, a non-display bezel area having a left bezel area, a right bezel area, a top bezel area, and a bottom bezel area, and a gap area between the display area and the non-display bezel area of the panel, the non-display bezel area at least partially surrounding the display area, and wherein the gap area has a non-infinitesimal width;

a first pattern of conducting material arranged on the display area of the panel, the first pattern of conducting material being transparent and being formed as a geometric shaped lattice with a first pitch; and

a second pattern of conducting material arranged on the bottom bezel area of the panel and being formed as a diamond shaped lattice with a second pitch;

a third pattern of conducting material arranged on the left bezel area and being formed as a diamond shaped lattice with a third pitch;

and a fourth pattern of conducting material arranged on the right bezel area and being formed as a diamond shaped lattice with a fourth pitch,

wherein the gap area includes a fifth pattern of conducting material and forms an insensitive area that separates the first pattern of conducting material from at least the second pattern of conducting material,

and wherein the first pitch is different from the second, third and fourth pitches.

2. The touch screen of claim 1, wherein the second pitch is different from the third and fourth pitches.

3. The touch screen of claim 2, wherein the third and fourth pitches are different from one another.

4. The touch screen of claim 1, further comprising a controller for sensing changes in capacitances of the first pattern of conducting material and the second pattern of conducting material as a result of a user interaction with the panel, and for determining whether the user interaction is located in the display area of the panel or the bezel area of the panel.

5. The touch screen of claim 1, wherein the gap area has a width of greater than 1 mm.

6. A method for providing a touch screen panel, the method comprising:

providing a first pattern of conducting material as a geometric shaped lattice with a first pitch in a display area of the touch screen panel, the first pattern of conducting material being transparent;

providing a second pattern of conducting material as a geometric shaped lattice with a second pitch in a non-display bezel area of the touch screen panel, wherein the second pattern is different from the first pattern; and

providing a third pattern of conducting material in a gap area between the display area and the non-display bezel area of the touch screen panel, wherein the gap area has a non-infinitesimal width;

providing a fourth pattern of conducting material as a geometric shaped lattice with a fourth pitch in the non-display bezel area of the touch screen panel; and

providing a fifth pattern is provided as a geometric shaped lattice with a fifth pitch in the non-display bezel area of the touch screen panel, and wherein the first pitch is different from the second, fourth, and fifth pitches,

wherein the gap area forms an insensitive area that separates the first pattern of conducting material from the second pattern of conducting material, and

wherein the first pitch is different from the second, fourth, and fifth pitches.

7. The method for providing the touch screen panel of claim 6, wherein providing the second pattern of conducting material in the non-display bezel area of the touch screen panel includes providing the second pattern of conducting material on a bottom bezel area of the touch screen panel, wherein providing the fourth pattern of conducting material includes providing the fourth pattern on a left bezel area of the touch screen panel, and wherein providing the fifth pattern of conducting material includes providing the fifth pattern on a right bezel area of the non-display bezel area of the touch screen panel.

8. The method for providing the touch screen panel of claim 6, wherein the second pitch is different from the third and fourth pitches.

9. The method for providing the touch screen panel of claim 6,

wherein providing the first pattern of conducting material in the display area of the touch screen panel and providing the second pattern of conducting material in the non-display bezel area of the touch screen panel comprises providing a transmitting conducting material and a reception conducting material, and

wherein providing the third pattern of conducting material in the gap area between the display area and the non-display bezel area of the touch screen panel comprises providing one of a transmitting conducting material or a reception conducting material in the gap area between the display area and the non-display bezel area of the touch screen panel to form the insensitive area that separates the first pattern of conducting material from the at least second pattern of conducting material.

10. The method for providing the touch screen panel of claim 9, further comprising providing a controller for sensing changes in capacitances of the first pattern of conducting material and the at least second pattern of conducting material as a result of a user interaction with the touch screen panel, the controller being used to determine whether the user interaction is located in the display area of the panel or the non-display bezel area of the touch screen panel.

11. The method of claim 6, wherein the second pitch is different from the fourth and fifth pitches.

12. The method of claim 6, wherein the fourth and fifth pitches are different from one another.

13. A system comprising:

a panel comprising a display area, a bezel area, and a gap area between the display area and the bezel area, wherein the gap area has a non-infinitesimal width;

a first pattern of conducting material arranged on the display area of the panel as a diamond shaped lattice with a first pitch, the first pattern of conducting material being transparent;

a second pattern of conducting material arranged on the bezel area of the panel as a diamond shaped lattice with a second pitch;

a third pattern of conducting material in the gap area between the display area and the bezel area of the panel, wherein the third pattern of conducting material forms an insensitive area that separates the first pattern of conducting material from the at least second pattern of conducting material;

a fourth pattern of conducting material arranged on the bezel area of the panel as a diamond shaped lattice with a fourth pitch;

a fifth pattern of conducting material arranged on the bezel area of the panel as a diamond shaped lattice with a fifth pitch

wherein the first pitch is different from the second, fourth and fifth pitches; and

a controller configured for sensing changes in capacitances of the first pattern of conducting material and configured for sensing changes in capacitances of the second pattern of conducting material as a result of a user interaction with the touch screen panel, the controller being further configured to determine whether the user interaction is located in the display area of the panel or in the bezel area of the panel.

14. The system of claim 13, wherein the second pattern of conducting material is arranged on a bottom bezel area of the panel, wherein the fourth pattern of conducting material is arranged on a left bezel area of the panel, and wherein the fifth pattern of conducting material is arranged on a right bezel area of the panel.

15. The system of claim 13, wherein the second pitch is different from the fourth and fifth pitches.

16. The system of claim 13, wherein the fourth and fifth pitches are different from one another.
