Abstract
The present invention provides a backlight module of a liquid crystal display (LCD), wherein a field emitting display is disposed at a backlight position of a liquid crystal panel module to be used as a backlight module of the display for providing the required backlight source. The field emitting display is composed of a plurality of carbon nanotubes to have a low operational voltage. The present invention has the characteristics of high brightness, power saving, super thinness, and capability of being used in rigorous environments.
Claims4
