Abstract

A display device is provided. The display device includes a light engine having light emitting components mounted to a flexible circuit board having a flexible graphite substrate. The flexible circuit board includes a dielectric layer formed on the surface of the flexible graphite substrate and an electrically conductive layer formed on the surface of the dielectric. The high in-plane thermal conductivity graphite substrate provides enhanced heat transfer capability to effectively move of heat away from the light emitting components for improved cooling of the heat generated by the light emitting component and surrounding devices.
