Abstract

A display system is provided including a display assembly with a display region of a first size, an overlay having a first substantially transparent section corresponding to the size of the display region of the display assembly and a second customized section extending beyond the first substantially transparent section, and an adhesive optically bonding the display region of the display assembly to the overlay. In some embodiments, the display assembly is one of a liquid crystal display, an organic light emitting diode display, and an electronic paper display. In some embodiments, the second customized section of the overlay may include an accessory, such as a sensor accessory, an actuator, or a coating.

Claims

1. A display system comprising:

a display assembly with a display region of a first size;

an overlay having a first substantially transparent section corresponding to the size of the display region of the display assembly and a second customized section extending beyond the first substantially transparent section; and

an adhesive optically bonding the display region of the display assembly to the overlay.

2. The display system of claim 1, wherein the display assembly is one of a liquid crystal display, an organic light emitting diode display, and an electronic paper display.

3. The display system of claim 1, wherein the adhesive optically bonds the display region of the display assembly to the first substantially transparent section of the overlay.

4. The display system of claim 1, wherein the second customized section of the overlay includes a sensor accessory.

5. The display system of claim 4, wherein the sensor accessory is a touch switch.

6. The display system of claim 1, wherein the second customized section of the overlay includes an actuator.

7. The display system of claim 6, wherein the actuator is one of an audio transducer, haptic vibrator, and a light source.

8. The display system of claim 1, wherein the second customized section of the overlay includes at least one non-transparent region.

9. The display system of claim 8, wherein the second customized section of the overlay includes at least one additional layer.

10. The display system of claim 8, wherein the at least one additional layer is an opaque coating.

11. The display system of claim 8, wherein the at least one additional layer is an anti-reflective coating.

12. The display system of claim 1, wherein the adhesive includes a two-part cured silicone adhesive.

13. The display system of claim 1, wherein the adhesive has a refractive index substantially similar to one of the first substantially transparent section of the overlay and an exterior surface of the display region of the display assembly.

14. The display system of claim 1, wherein the second customized section extends beyond the first substantially transparent section along at least two sides.

15. The display system of claim 1, further comprising a second substantially transparent section spaced apart from the first substantially transparent section.

16. A bezelless display system comprising:

a display assembly;

an overlay with a customized section and a transparent section, where the transparent section is adhesively coupled using an optical adhesive to the display assembly without coupling of the overlay to the display assembly with a mechanical bezel; and

at least one sensor coupled to the customized section of the overlay.

17. The display system of claim 16, wherein the display assembly is one of a liquid crystal display, an organic light emitting diode display and an electronic paper display.

18. The display system of claim 16, wherein the at least one sensor is a touch sensor.

19. The display system of claim 16, wherein the customized section of the overlay extends beyond the display assembly on at least two sides.

20. A method for construction of a display system comprising:

applying an optical adhesive to a substantially transparent section of an overlay;

customizing a second section of the overlay;

aligning the transparent section of the overlay with a viewable portion of a display assembly; and

bonding the overlay and the display assembly.

21. The method of claim 20, wherein customizing the second section of the overlay includes adhering a sensor to the second section of the overlay.

22. The method of claim 21, wherein customizing the second section of the overlay includes adhering a touch switch to the second section of the overlay.

23. The method of claim 20, wherein customizing the second section of the overlay includes applying a coating to at least a portion of the second section.

24. The method of claim 20, wherein aligning the transparent section of the overlay with a viewable portion of a display assembly includes positioning the display assembly such that the second section of the overlay extends beyond at least one side of the transparent section of the overlay.

25. The method of claim 20, further comprising pre-curing the optical adhesive and the overlay prior to aligning the transparent section of the overlay with the viewable portion of the display assembly.
