Abstract

A backlighting display assembly for an LCD that utilizes a plurality of LEDs that are in spaced relation adjacent to the LCD such that the LEDs do not directly light the LCD and instead a reflective material such as a potted material is placed in parallel spaced alignment from the LCD and LEDs such that light is reflected off of the reflected surface to illuminate the interior LCD and open target areas of the circuit board of the assembly thus providing proper lighting for the LCD, transparent and semi-transparent areas of the graphic overlay of the control panel.

Claims (9)

1. A backlight display assembly having an interior comprising:

a circuit board having a plurality of target areas;

a plurality of LEDs electrically connected to the circuit board;

an LCD adjacent to the LEDS and electrically connected to the circuit board;

a reflective surface positioned in parallel spaced alignment from the LCD such that light from the LEDs is reflected off the reflective surface and onto the LCD and circuit board;

wherein the LEDs are placed in spaced relation such that light is diffused evenly over the interior of the assembly including the LCD and circuit board to provide backlighting to the open target areas of the circuit board; and

wherein the open target areas of the circuit board are within a graphic overlay.

2. The backlighted display assembly of claim 1 wherein the reflective surface is a potted surface.

3. The backlighted display assembly of claim 1 wherein the plurality of LEDs are aligned in parallel spaced relation to illuminate the circuit board.
