Abstract

A method, system, and display assembly is disclosed herein. The aspects disclosed herein include the providing of at least two lenses covering a respective display, with the two lenses bonded together with an optical clear adhesive. The optical clear adhesive may be shaped in a predetermined manner, such as a curve. Also included herein are systems for driving electronic signals to the respective displays. The signals may undergo processing in order to provide a seamless look via the display assembly.

First claim

We claim:

1. A display assembly, comprising:
a first lens connected to a first display driver, the first lens having a first edge and a second edge;
a second lens connected to a second display driver, the second lens having a first edge and a second edge, the second lens forming an angle with the first lens by directly abutting the second edge of the first lens and the first edge of the second lens; and
an adhesive layer applied to the first lens and the second lens,
the adhesive layer forming a non-linear surface,
the non-linear surface beginning at the first edge of the first lens and ending at the second edge of the second lens, and
the non-linear surface being only disposed on a visible portion of the first and second lenses,
wherein the adhesive layer forms a partial cylindrical-shaped object, and
wherein a circular surface of the partial cylindrical-shaped object is formed by an outwardly curved surface forming from the first edge of the first lens to the second edge of the second lens.

2. The assembly according to claim 1 , wherein the first display driver and the second display driver are electrically coupled to a source, the source being configured to generate display data via both the first display driver and the second display driver.

3. The assembly according to claim 2 , wherein display data is further configured to be split into a first portion communicated to the first display driver, and a second portion communicated to the second display driver.

4. The assembly according to claim 1 , wherein the adhesive layer is an optically clear adhesive (OCA).

5. The assembly according to claim 4 , wherein the OCA is a liquid optical clear adhesive.

6. The assembly according to claim 4 , wherein the OCA is a provided with a predefined shape.

7. The assembly according to claim 6 , wherein the predefined shape is a curve.

8. The assembly according to claim 7 , wherein the predefined shape is convex.

9. The assembly according to claim 1 , wherein the first lens and the second lens are rectangular and flat.

10. A method for providing a seamless display with multiple lenses, each of the multiple lenses being associated with a respective display, comprising:
providing a first lens associated with a first display, the first lens having a first edge and a second edge;
providing a second lens associated with a second display, the second lens having a first edge and a second edge;
orientating the first lens and the second lens with each other lens by directly abutting the second edge of the first lens and the first edge of the second lens; and
providing an adhesive layer on both the first lens and the second lens,
the adhesive layer forming a non-linear surface,
the non-linear surface beginning at the first edge of the first lens and ending at the second edge of the second lens, and
the non-linear surface being only disposed on a visible portion of the first and second lenses,
wherein the adhesive layer forms a partial cylindrical-shaped object, and
wherein a circular surface of the partial cylindrical-shaped object is formed by an outwardly curved surface forming from the first edge of the first lens to the second edge of the second lens.

11. The method according to claim 10 , wherein the adhesive layer is providing a predetermined shape on a surface opposing a viewer of the seamless display.

12. The assembly according to claim 1 , wherein the partial cylindrical-shaped object is at most a semi-cylinder.
