Heat spreader for display device
First Claim
1. A heat spreader for a display device, comprising at least one sheet of compressed particles of exfoliated graphite having two major surfaces, each of the major surfaces having a layer of an adhesive material thereon, wherein the heat spreader further comprises a biasing material which comprises a foam and which forces the heat spreader against a display device to which the heat spreader is applied in response to pressure applied to the biasing material by the structural chassis of the display device, to increase thermal contact between the heat spreader and the display device.

22. A display device, comprising:
-
(a) a display device having a structural chassis; (b) a heat spreader applied to the display device, wherein the heat spreader comprises at least one sheet of compressed particles of exfoliated graphite having two major surfaces, at least one of the major surfaces having a layer of an adhesive material thereon, one of the major surfaces further having a biasing material having two major surfaces adhered thereto such that a first major surface of the biasing material is adhered to the at least one sheet of compressed particles of exfoliated graphite, wherein the biasing material comprises a foam and forces the heat spreader against the display device in response to pressure applied to the biasing material by the structural chassis, for greater thermal contact. - View Dependent Claims (23, 24, 25, 26, 27, 28)
