Abstract

An image display device comprising an image display panel, heat dispersion material positioned proximate to the image display panel, a frame system including a framework positioned proximate to the heat dispersion material opposite the image display panel, and a plurality of electronic components engaging the framework, where the image display device exhibits a support factor of less than about 375 mm-W/m° K. The framework can be adhesively bonded to the heat dispersion material. The framework can include a height and a width wherein the heat dispersion material substantially spans the height and the width. Additionally, a first cross support can span the framework and a plurality of second electronic components can engage the first cross support. Additionally a second cross support can span the framework wherein at least one of the second electronic components engages the second cross support.

Claims

1. A image display device comprising:

an image display panel;

heat dispersion material position proximate to the image display panel; and

a frame system comprising

(ii) a plurality of electronic components engaging the open frame,

wherein the image display device exhibits a support factor of less than about 375 mm-W/m°

K.

2. The image display device of claim 1, further including a first cross support spanning the framework and a plurality of second electronic components engaging the first cross support.

3. The image display device of claim 2, further including a second cross support spanning the framework wherein at least one of the second electronic components engages the second cross support.

4. The image display device of claim 1, further including an adhesive bonding the framework to the heat dispersion material.

5. The image display device of claim 1, wherein the framework including a height and a width, wherein the heat dispersion material substantially spans the height and the width of the framework.

6. The image display device of claim 1, wherein the heat dispersion material comprises at least one sheet of compressed particles of exfoliated graphite.

7. An image display device comprising:

an image display panel including an image display side;
