New Description: [New Technology Field] This creation is about a backlight module, especially the spacer layer can be used to adjust the distance between the light-emitting diode and the light guide plate to obtain a better light source emission angle. Backlight module. [Prior Art] Liquid crystal displays have the advantages of low power consumption, low radiation, and light weight. In recent years, liquid crystal displays have gradually replaced conventional image tube displays as a main display device regardless of company or general household. The liquid crystal display controls the light transmission of each pixel position by the liquid crystal layer of the liquid crystal panel, so that the liquid crystal display can display images by being married. The = crystal panel is a non-self-luminous display material. Therefore, the liquid crystal display must be equipped with an external light source and a light guiding device, such as a backlight module. Currently, it is used in liquid crystal display. Take [ED as the light source and use the design of the light guide plate to control the direction of light travel. Please refer to the first figure, the backlight module used in ▲, the conventional backlight module 1, including: a lampshade... used month, circuit board 12, (not shown in the first figure), plural A light-emitting device, a reflective sheet 14, and a well plate 15'.

Of course, in addition to the liquid crystal panel 18 and the optical film 17', there are other optical panels in the liquid crystal display. This is not to be described much. As shown in the second figure, since the conventional backlight module is used to place the circuit board 12' and the light-emitting device 13 within the lamp cover 11', the bottom of the 'light cover 11' is usually made larger. In order to make the conventional backlight module Γ integrated in the liquid crystal display, it can be combined with the liquid crystal panel 18', the optical film 17' and other optical panels M375906 in combination with the 'shade 1 1 ' The shape of the concave fold, in addition, is more than the optical film 1 7 'gold rub 1 , / / is added between a spacer layer 16', so that the optical film 17' disk tomb 4c 〇 V first plate 15 , able to fit more firmly.
