Display device with heat spreader

摘要

The present invention provides a display device comprising a display panel; a plurality of heat sources generating a region of localized higher temperature on the display panel; and a heat spreader (10) comprising at least one sheet of compressed particles of exfoliated graphite having two major surfaces (12, 14), the heat spreader having a surface area greater than the surface area of a localized higher temperature region on the back surface of the display panel, wherein substantially all of one of the major surfaces (12) is in thermal contact with the panel, further including a protective coating (20) disposed on the second major surface (14), wherein the heat spreader (10) is capable of reducing the temperature difference between locations on the display panel.
