Claim Text:
1. An image display device having improved temperature uniformity, the display device comprising: a) an image display panel; and b) a frame system comprising wherein the image display panel comprises a plurality of heat sources; wherein the heat dispersion material comprises at least one sheet of compressed particles of exfoliated graphite having an in-plane thermal conductivity of at least about 250 W/m·K and a thermal anisotropic ratio of no less than about 10; wherein the frame system exhibits a support factor of less than about 150 mm·W/m·K, wherein the support factor is determined by multiplying the thickness of the metal support member by its in-plane thermal conductivity; and wherein the image display device exhibits improved temperature uniformity as compared to an image display device having a frame system which exhibits a support factor of less than 150 mm·W/m·K but does not include a heat dispersion material having an in-plane thermal conductivity of at least 250 W/m·K and a thermal anisotropic ratio of no less than 10 proximate to the metal support member.
