Claims24
A display device, comprising a heat spreader having two major surfaces, the heat spreader comprising at least one sheet of compressed particles of exfoliated graphite wherein substantially all of one of the major surfaces of the heat spreader direct thermal is in contact with the display device, and further wherein the heat spreader comprises a facing layer adhered to a major surface of the at least one sheet of compressed particles of exfoliated graphite and interposed between the sheet of compressed particles of exfoliated graphite and the display device.
A display device, comprising a heat spreader having two major surfaces, the heat spreader comprising at least one sheet of compressed particles of exfoliated graphite, wherein substantially all of one of the major surfaces of the heat spreader direct thermal is in contact with the display device wherein at least a portion of the at least one sheet of compressed particles of exfoliated graphite is coated with a protective coating sufficient to inhibit flaking of particles of graphite.
