Patent ID: 7666270

Claim:
A method for cooling a collection of light-emitting heat sources in a liquid crystal display panel by applying a heat spreader thereto, the method comprising (a) providing an anisotropic heat spreader composite having two major surfaces and a thickness between the major surfaces, which comprises a heat spreader material comprising at least one sheet of compressed particles of exfoliated graphite, each heat spreader composite having an adhesive thereon and a release material positioned such that the adhesive is sandwiched between the heat spreader material and the release material, wherein the adhesive achieves a minimum lap shear adhesion strength of at least about 125 grams per square centimeter; (b) removing the release material from the composite; and (c) applying the composite to a liquid crystal display panel such that the adhesive adheres the heat spreader composite to the panel ensuring direct thermal contact between the heat spreader and the collection of light-emitting heat sources in the panel while the panel assumes any of a variety of orientations, wherein the heat spreader cools the collection of light-emitting heat sources in the liquid crystal display panel.
