Abstract

An exemplary touch sensitive display ( 200 ) includes a display device ( 220 ) and a touch panel ( 210 ). The touch panel is attached on the display device through two adhesives ( 231, 232 ). The two adhesives have different adhesive capabilities.

Claims (29)

1. A touch sensitive display, comprising:

a display device; and

a touch panel attached on the display device through at least two adhesives mounted directly to either the touch panel or the display device, wherein all of the at least two adhesives are mounted on the same surface;

wherein the at least two adhesives have different adhesive capabilities, one of the at least two adhesives having a stronger adhesive capability than another one of the at least two adhesives.

2. The touch sensitive display of claim 1 , wherein the at least two adhesives are arranged at a periphery of the touch sensitive display between the touch panel and the display device.

3. The touch sensitive display of claim 1 , wherein the at least two adhesives are arranged side by side, between a peripheral area of the touch panel and a peripheral area of the display device, with the one of the at least two adhesives being nearer an outside of the touch sensitive display than the other one of the at least two adhesives.

4. The touch sensitive display of claim 1 , wherein the at least two adhesives comprise three adhesives, being a first adhesive, a second adhesive, and a third adhesive arranged side by side at a periphery of the touch sensitive display between the touch panel and the display device.

5. The touch sensitive display of claim 1 , wherein the display device is any item selected from the group consisting of a liquid crystal display, cathode ray tube display, flat intelligent tube display, light emitting diode display, plasma display panel, organic light emitting display, and field emission display.

6. The touch sensitive display of claim 1 , wherein the touch panel is any item selected from the group consisting of a resistance type touch panel, static-electricity-capacitance type touch panel, pressure-sensor type touch panel, and infrared ray type touch panel.

7. The touch sensitive display of claim 1 , wherein the at least two adhesives are selected from the group consisting of a hot-melt adhesive and a light-curable adhesive.

8. The method of claim 1 , wherein the one of the at least two adhesives having the weaker adhesive capability is thicker than the other one of the at least two adhesives having the stronger adhesive capability.

9. The method of claim 8 , wherein an interval is defined between the one of the at least two adhesives and the other one of the at least two adhesives.

10. A touch sensitive display device, comprising:

a touch sensitive plate;

a display device; and

at least two adhesives with different adhesive capabilities mounted directly to either the touch sensitive plate or the display device, wherein all of the at least two adhesives are mounted on the same surface, one of the at least two adhesives having a stronger adhesive capability than another one of the at least two adhesives, the at least two adhesives bonding the touch sensitive plate and the display device together.

11. A method for fabricating a touch sensitive display, the method comprising:

providing a display, a touch panel, and at least two adhesives with different adhesive capabilities, a second one of the at least two adhesives having a stronger adhesive capability than a first one of the at least two adhesives;

applying the at least two adhesives directly on either the touch panel or on the display, wherein all adhesives are applied on the same surface;

moving the touch panel onto the display, with at least one of the at least two adhesives preliminarily adhering the touch panel and the display together;

determining whether the preliminarily adhered touch panel and display satisfy one or more predetermined specifications for the touch sensitive display; and

firmly adhering the touch panel and the display together by all of the at least two adhesives.

12. The method of claim 11 , wherein the first and second adhesives are applied side by side on a peripheral area of the touch panel or the display.

13. The method of claim 11 , wherein after the first and second adhesives are applied on the touch panel or the display and before the touch panel and the display together are adhered together, the first adhesive having the weaker adhesive capability is thicker than the second adhesive having the stronger adhesive capability.

14. The method of claim 13 , wherein a thickness ratio of the first adhesive to the second adhesive is in a range of 1.2:1 to 4.0:1.

15. The method of claim 13 , wherein an interval is defined between the first adhesive and the second adhesive.

16. The method of claim 15 , wherein a width of the interval is in the range of 20%-80% of a corresponding width of the first adhesive.

17. The method of claim 11 , wherein the one or more predetermined specifications comprise the touch panel being in correct position relative to the display.

18. The method of claim 11 , wherein the at least one of the at least two adhesives which preliminarily adheres the touch panel and the display together is the first adhesive that has the weaker adhesive capability than the second adhesive.
