Display device having improved properties

摘要

An image display device having improved properties, comprising an image display panel, heat dispersion material positioned proximate to the image display panel, an open frame positioned proximate to the heat dispersion material opposite the image display panel, and a plurality of electronic components engaging the open frame, the image display device exhibits a support factor of less than about 375 mm-W/m° K.

主权项

1. A method for improving a characteristic of the frame system of an image display device comprising:
providing frame system which comprises a support member to which is attached an image display panel; providing a heat dispersion material 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 positioned proximate to the image display panel, the heat dispersion material comprising at least one sheet of compressed particles of exfoliated graphite, wherein the frame system exhibits a support factor of less than about 150 mm-W/m-K, where the support factor is determined by multiplying the thickness of the support member by its in-plane thermal conductivity and further 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 about 150 mm-W/m-K but does not include a heat dispersion material 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 positioned proximate to the image display panel.
