Embodiment Construction

[0013] Please refer to FIG. 2 , which is a schematic diagram of the first embodiment of the backlight system of the present invention. The backlight system 30 includes a light guide plate 32 and a reflective film 36 disposed below the light guide plate 32. The light guide plate 32 has a light-emitting surface 328, a bottom surface 327 opposite to the light-emitting surface 328, and a side surface adjacent to the bottom surface 327. 324, 325, 326 and 329. The light guide plate 32 is provided with a through hole 33 adjacent to a side surface 326. The through hole 33 includes an entrance 331 and an exit 333. I-shaped, the through hole 33 is filled with fluorescent powder 332, mercury 334 and inert gas 336, and electrodes 338 are respectively added to the two ends of the through hole 33. The electrodes 338 at both ends are respectively provided with wires 341, thereby forming a light guide plate 32 integrated with the light source.

Abstract

The present invention relates to a backlight system. It includes a light-conducting plate and a light source. Said light-conducting plate has a light-exiting surface, a bottom surface opposite to said light-exiting surface and several side surfaces adjacent to said light-exiting surface, and in the light-conducting plate interior is set a through hole close to said several side surfaces. Said through hole includes an inlet and an outlet, said inlet and outlet are positioned in said several side surfaces. Said light source is formed by charging phosphor powder, mercury and inert gas into the through hole interior and respectively adding electrode on its two ends.

Description

【Technical field】 [0001] The invention relates to a backlight system applied to a liquid crystal display. 【Background technique】 [0002] Liquid crystal displays are mainly used in various information, communication, and consumer products, such as personal computers, LCD TVs, mobile phones, video phones, and PDAs. Because the liquid crystal display panel itself does not have luminous properties, a backlight system is required to provide it with uniform and high-brightness planar light to obtain good visual effects. [0003] A prior art backlight system is shown in FIG. 1 . The backlight system 10 includes a light guide plate 1, a reflection plate 2 located on the bottom surface 11 side of the light guide plate 1, a diffuser plate 3 located on the light exit surface 12 side of the light guide plate 1, and a diffuser plate 3 located on the light incident surface 13 side of the light guide plate 1. The light source 6, the light source cover 7 and the two prism plates 4, 5 loc...
