Description of the invention (4) 30 μηι 'is more preferably 20 μιη; the connection method of the reflective sheet and the light guide plate is not limited, and It is best to attach it, but it can also be assembled easily. The light source is preferably located on or soldered to a printed circuit board, but is not limited thereto. The reflective sheet may be located on a printed circuit board like the light source, but it may not be located on the printed circuit board, but may be in contact with the light guide plate in other ways. In order to make your reviewing committee better understand the technical content of the present invention, the two preferred embodiments are described below. Please refer to FIG. 2, which is a cross-sectional view of a preferred embodiment of the present invention, wherein the reflective sheet is a non-conductive reflective sheet. In FIG. 2, the light source 2 10 used is, for example, a light emitting diode, and the light source 2 is located on a printed circuit board 250. A light guide plate 22o is provided on the light emitting side of the light source 210, and a liquid crystal display panel 230 is placed above the light guide plate 220.

Description of the invention (5) The shorter the distance, the better the reflection effect. The distance is preferably closer to zero but not equal to zero. In addition, the reflective sheet 3 40 is located on a printed circuit board 350 as the light source, separated from each other by a small gap; the reflective sheet 340 covers at least a part of the light guide plate 320, and Part of the light guide plate 320 is in close contact to prevent light leakage, and is bounded between [CD panel 3 30 and light guide plate 3 2 0. The backlight module is displayed as the backlight module 'light reflected by the light source reflection unit < light does not completely enter the light guide plate, but part of it is lost, resulting in reduced brightness; and the light at the edge of the light guide plate often has non-total reflection , And light leaks directly at the edge of the light guide plate, resulting in bright bands at the edge of the screen. In the backlight module of the present invention, a reflective sheet is added between the liquid crystal display (LCD) panel and the light guide plate, so that the light that was originally lost or lost can be reflected back to the light guide plate through the reflective sheet to reuse the originally lost light. Light to increase panel brightness. And the reflection sheet partially shields the edge of the light guide plate, and the I light directly emitted at the edge of the light guide plate can be reflected back to the light guide plate to reduce the occurrence of bright bands on the edge of the screen. As can be seen from the above, the device can be achieved without strengthening the light source Panel brightness increase effect, and has the advantages of eliminating bright edges on the screen. Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes and retouching without departing from the spirit of the present invention. Therefore, The protection scope of the present invention shall be subject to the definition in the attached patent application park.
