Abstract

A moisture resistant pad for a liquid crystal panel, including at least one moisture resistant construction including a central region and an edge region disposed around the central region, wherein the edge region includes a first undulation structure disposed around the central region, the first undulation structure being a closed structure for blocking water vapor out of the central region. In the moisture resistant pad for a liquid crystal panel, channels formed within a surface of a product that needs to be moisture resistant are isolated from the external environment so that water vapor in the external environment cannot contact the product surface through the channels. As a result, the pad has good moisture resistance, suitable in transportation environments or in packaging container environments.

First claim

The invention claimed is:

1. A moisture resistant pad for a liquid crystal panel comprising:
a main body; and
a first surface and a second surface opposite with each other and respectively positioned at both sides of the main body, wherein the first surface is provided with a first moisture resistant construction and the second surface is provided with a second moisture resistant construction,
wherein each of the first moisture resistant construction and the second moisture resistant construction comprises a central region and an edge region disposed around the central region, wherein the edge region comprises a first undulation structure disposed around the central region, wherein the first undulation structure is a closed structure for keeping water vapor out of the central region,
wherein the first undulation structure of the first moisture resistant construction and the first undulation structure of the second moisture resistant construction are symmetrically arranged,
wherein for each of the first moisture resistant construction and the second moisture resistant construction:
the first undulation structure comprises a first annular projection and a second annular projection, each of which is in a shape of a closed loop and is disposed at an edge of the moisture resistant construction along a circumference of the moisture resistant construction,
the second annular projection nests inside the first annular projection and forms an edge depressed region between the first annular projection and the second annular projection, and
a central depressed region is formed inside the second annular projection for housing the liquid crystal panel.

2. A system for protecting a liquid crystal panel from moisture wherein, for the liquid crystal panel that needs moisture protection, there are a plurality of moisture resistant pads stacked with each other, each moisture resistant pad comprising:
a main body; and
a first surface and a second surface opposite with each other and respectively positioned at both sides of the main body, wherein the first surface is provided with a first moisture resistant construction and the second surface is provided with a second moisture resistant construction,
wherein each of the first moisture resistant construction and the second moisture resistant construction comprises a central region and an edge region disposed around the central region, wherein the edge region comprises a first undulation structure disposed around the central region, wherein the first undulation structure is a closed structure for keeping water vapor out of the central region,
wherein the first undulation structure of the first moisture resistant construction and the first undulation structure of the second moisture resistant construction are symmetrically arranged,
wherein for each of the first moisture resistant construction and the second moisture resistant construction:
the first undulation structure comprises a first annular projection and a second annular projection, each of which is in a shape of a closed loop and is disposed at an edge of the moisture resistant construction along a circumference of the moisture resistant construction,
the second annular projection nests inside the first annular projection and forms an edge depressed region between the first annular projection and the second annular projection, and
a central depressed region is formed inside the second annular projection for housing the liquid crystal panel.
