A display apparatus is provided having a back light generated by waste heat of a system. A thermally illuminated strip is disposed on a surface of the display apparatus. The system has heat generating components, such as a CPU, which produce excess waste heat. A heat pipe conveys the heat from the heat generating components to the thermally illuminated strip. Once the heat generating component warms up, the thermally illuminated strip is illuminated by the conveyed heat and provides back lighting for the display apparatus. Although several other applications are appropriate, one particular application for the display apparatus is for a status LCD within a computer.
