Abstract

A method for providing a bonded glass component for use in an LCD display. A frame is sealed to a glass component. A barrier coat is then applied to the sealant. An adhesive is poured over the entirety of the glass component and the frame. Starting at one edge of the glass component a second glass component is lowered down until an adhesive wave progresses across the glass component, until the second glass component in position.

Claims

1. A method of bonding glass components, comprising:

providing a first glass component having a first surface and a perimeter;

providing a frame having a top portion which continuously overlaps the perimeter of the first surface of the first glass component;

sealing the first glass component and the frame with a sealant;

allowing the sealant to cure;

applying a barrier coat over the sealant;

allowing the barrier coat to cure;

pouring an adhesive over the first surface of the first glass component and the top portion of the frame;

placing a second glass component, having a first and second edge, such that the first edge is in contact with the top portion of the frame and the second edge is elevated above the first glass component; and

lowering the second edge of the second glass component till the second glass component is substantially parallel with first glass component.

2. The method of claim 1 further comprising:

applying a skirting tape around the frame prior to pouring the adhesive.

3. The method of claim 2 further comprising:

removing the skirting tape from the frame.

4. The method of claim 1 wherein the sealant is applied with a brush.

5. The method of claim 1 wherein the adhesive is interposed between the second glass component and the first glass component and the frame.

6. The method of claim 1 wherein the first glass component is an LCD display.

7. The method of claim 1 wherein the first glass component is a glass plate.

8. A method of bonding glass components, comprising:

providing a first glass component having a first surface and a perimeter;

providing a frame having a top portion which continuously overlaps the perimeter of the first surface of the first glass component;

sealing the first glass component and the frame with a sealant;

allowing the sealant to cure;

pouring an adhesive over the first surface of the first glass component and the top portion of the frame;

placing a second glass component, having a first and second edge, such that the first edge is in contact with the top portion of the frame and the second edge is elevated above the first glass component; and

lowering the second edge of the second glass component till the second glass component is substantially parallel with first glass component.

9. The method of claim 8 further comprising:

applying a skirting tape around the frame prior to pouring the adhesive.

10. The method of claim 9 further comprising:

removing the skirting tape from the frame.

11. The method of claim 8 wherein the sealant is applied with a brush.

12. The method of claim 8 wherein the adhesive is interposed between the second glass component and the first glass component and the frame.

13. The method of claim 8 wherein the first glass component is an LCD display.

14. The method of claim 8 wherein the first glass component is a glass plate.

15. A method of bonding glass components, comprising:

providing a first glass component having a first surface and a perimeter;

providing a frame having a top portion which overlaps the perimeter of the first surface of the first glass component;

sealing the first glass component and the frame with a sealant;

allowing the sealant to cure;

applying a barrier coat over the sealant;

allowing the barrier coat to cure;

pouring an adhesive over the first surface of the first glass component and the top portion of the frame;

placing a second glass component, having a first and second edge, such that the first edge rests atop the adhesive at the intersection of the first surface and the top portion of the frame and the second edge is elevated above the first glass component; and

lowering the second edge of the second glass component until the second glass component is substantially parallel with the first glass component and within the top portion of the frame.

16. The method of claim 15 wherein the sealant is applied with a brush.

17. The method of claim 15 wherein the adhesive is interposed between the second glass component and the first glass component and the frame.

18. The method of claim 15 wherein the first glass component is an LCD display.

19. The method of claim 15 wherein the first glass component is a glass plate.
