System and method for instrument panel with color graphical display
First Claim
1. A message center comprising:
- a liquid crystal display (LCD), the LCD being divided into one or more zones, each zone being designated for a specific message;
a light guide system positioned behind the liquid crystal display, the light guide system having one or more light guides, with each of the light guides having a first end, each of the light guides aligned with a zone of the liquid crystal display;
a multi-color light emitting diode (LED) mounted at the first end of each of the light guides, each multi-color LED being configured to selectively emit a plurality of light colors; and
a control system that sets the intensity of each of the multi colors on plurality of light colors emitted from each of the LEDs such that a backlighting of each zone is individually controlled;
wherein each of the light guides has a second end, with each of the light guides narrowing toward the second ends.

Abstract
A message center that can comprise a liquid crystal display (LCD) is provided. The LCD can be divided into one or more zones, with each zone being designated for a specific message. The message center can also include a light guide system positioned behind the liquid crystal display. The light guide system can have one or more light guides, with each of the light guides having a first end, and each of the light guides can be aligned with a zone of the liquid crystal display. The message center can further include a multi-color light emitting diode (LED) that can be mounted at the first end of each of the light guides, and a control system that can set the intensity of each of the multi-colors on each of the LEDs such that a backlighting of each zone is individually controlled.
