Abstract

The described embodiments relate generally to liquid crystal displays (LCDs) and more particularly to thermal management of heat produced by an illumination source in an LCD module. High temperatures generated by the illumination source can cause color shifts in the LCD due to changes in any included LEDs and liquid crystals. One solution is to house the LCD module in a metal chassis and thermally couple the LED light bar to the metal chassis. Furthermore, the LCD module can be kept at a uniform temperature by transferring heat from a region near the LED light bar to a relatively cooler region of the LCD module. These approaches can minimize any alterations or shifts in color resulting from heat from the LED light bar.

First claim

What is claimed is:

1. A computing device, comprising:
a chassis formed of a thermally conductive material and configured to support operating components;
a liquid crystal display (LCD) module having a proximal edge and distal edge opposite the proximal edge, the LCD module comprising:
an illumination source located proximate to the proximal edge and configured to provide light and heat,
a light guide configured to receive and internally disperse at least some of the light pr…
