Abstract: The represent invention relates to a method of backlighting a liquid crystal display which includes heating a fluorescent lamp with an external heating element which does not contact the lamp. The heating step may be accomplished by passing a current through a resistive material. The resistive material may be coated on to a surface. The present invention also relates to a backlighting system with a fluorescent lamp and an external heating element which does not contact the fluorescent lamp. The heating element may be a resistive material coated on a substrate. The present invention also relates to a portable display device element includes a liquid crystal display, a fluorescent lamp to act as a backlight, a heating element which does not contact the fluorescent lamp and optionally including reflectors, diffusers, and optical enhancement films. The heating element may be a resistive material coated on a substrate.
