Abstract

A lens assembly, and a method for providing a lens assembly is disclosed herein. The lens assembly includes a first frame piece with a first edge on the direction in which a viewer of the electronic display would face, the first edge forming a first angle with a second edge; a second frame piece with a third edge on the direction in which a viewer of the electronic display would face, the third edge forming a second angle with a fourth edge; a lens with a first lens edge facing the viewer, a second lens edge and third lens edge connected to the first lens edge and forming a lens angle; a first adhesive layer placed between the second edge and the second lens edge to attach the first frame piece to the lens; and a second adhesive layer placed between the fourth edge and the third lens edge to attach the second frame piece to the lens.

First claim

We claim:

1. A lens assembly for an electronic display, comprising:
a first frame piece with a first edge on a direction in which a viewer of the electronic display would face, the first edge forming a first angle with a second edge;
a second frame piece with a third edge on the direction in which the viewer of the electronic display would face, the third edge forming a second angle with a fourth edge;
a lens with a first lens edge facing the viewer, a second lens edge and a third lens edge connected to the first lens edge and forming a first lens angle and a second lens angle, respectively;
a first adhesive layer placed between the second edge and the second lens edge to attach the first frame piece to the lens; and
a second adhesive layer placed between the fourth edge and the third lens edge to attach the second frame piece to the lens,
wherein a shape of the lens is a trapezoidal prism, and the first and the second adhesive layers are placed on non-parallel sides of the trapezoidal prism.

2. The lens assembly according to claim 1 , wherein the electronic display is integrated into a center stack area of a vehicle.

3. The lens assembly according to claim 1 , wherein the first angle and the second angle are less than 90 degrees.

4. The lens assembly according to claim 3 , wherein the first and the second lens angles are more than 90 degrees.

5. The lens assembly according to claim 1 , wherein the first and the second adhesive layers are defined by a Youngs modulus property ranging from between 0.1 through 10 Mpa.

6. The lens assembly according to claim 1 , wherein a size of a gap between the first edge of the lens and at least one of the first adhesive layer and the second adhesive layer is spaced based on a predetermined determination as a function of temperature range, size of the lens and differential coefficient of expansion of the first and the second frame pieces and the lens.

7. The lens assembly according to claim 1 , wherein the lens includes a first surface and a second surface, the first surface and the second surface defining opposing sides of the lens, the first surface and the second surface being rectangular shaped, with the first surface have a smaller surface area than the second surface.

8. The lens assembly according to claim 7 , wherein the first surface defines a front portion of the electronic display.

9. The lens assembly according to claim 1 , further comprising at least a first gap, the first gap being formed by a first surface of the first adhesive layer, and being in between the second edge and the second lens edge.

10. The lens assembly according to claim 1 , further comprising at least a second gap, the second gap being formed by a second surface of the first adhesive layer, and being in between the second edge and the second lens edge, the second surface being on an opposing side of the first adhesive layer.
