Abstract: A flat panel backlight unit having primary application in providing the backlight requirements of LCD monitors, and structured from flat glass panels including a top panel and a bottom panel joined together. An internal surface of the bottom panel is covered with a layer of protective film and fluorescent agent, and an inert gas is filled between the top and bottom panels. The fluorescent agent releases light after undergoing electric discharge, which forms the oriented light source that provides a backlight source for the LCD monitor.

Abstract: The present invention relates to a fluorescent tube structure, which fluoresces when connecting electric power, including a base plate and an upper cover forming a enclosed discharge chamber, wherein pellicles applied inside to enable an illuminant to project to the curved surface of the upper cover and then be reflected to the base plate, which enhances illumination and also reduces illumination loss to the lateral, thereby improving illuminant efficiency. The present invention can be used as a backlight on illuminating and electronic display devices.
