  • Patent number: 11352193
    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.
