  • Patent number: 6469449
    Abstract: A self-powered cold temperature capable flat panel display is provided to use a heat byproduct from a group of PEM fuel cells to warm the flat panel display of a laptop computer. The self-powered cold temperature capable flat panel display system comprises a flat panel display, a PEM fuel cell assembly, a means for separating the display from the PEM fuel cell assembly and a hydrogen fuel source. A slot is located below the panel and the PEM fuel cell assembly is sufficiently thin to provide adequate space in the slot for the insertion of both the separation means and the PEM fuel cell assembly. Other embodiments include a cold temperature display system and an all-climate panel display and a method for warming a panel display.
