Screen temperature reduction and improved screen temperature uniformity are ongoing objectives for flat panel display manufacturers as they seek to improve image quality, increase brightness and luminous efficiency, and extend screen life. This paper describes the development of new natural graphite‐based heat spreaders for both plasma and liquid crystal displays. Reductions in peak hot‐spot temperatures of up to 9 °C have been demonstrated in commercial flat panel displays, significantly reducing the potential for temperature‐induced performance degradation mechanisms in all types of display.
