Abstract

A liquid crystal display assembly (1) comprises a liquid crystal display (6), a lens (2), and a membrane (4) filled with substantially clear liquid between the lens (2) and the liquid crystal display.

Claims

1. A liquid crystal display device comprising:

a housing;

a liquid crystal display panel mounted in the housing;

a lens mounted above the liquid crystal display; and

a liquid filled membrane mounted between the lens and the liquid crystal display panel.

2. The liquid crystal display device of claim 1, wherein said device comprises a communication device.

3. The liquid crystal display device of claim 2, wherein said device comprises a pager.

4. The liquid crystal display device of claim 2, wherein said device comprises a radio.

5. The liquid crystal display device of claim 1, wherein the liquid filled membrane comprises a substantially transparent rubber bladder.

6. The liquid crystal display device of claim 1, wherein the liquid in the liquid filled membrane comprises a substantially transparent liquid.

7. The liquid crystal display device of claim 1, wherein the liquid in the liquid filled membrane comprises water.

8. A liquid crystal display assembly, comprising:

a liquid crystal display;
