The light-emitting diode is used as a light source, and the light-emitting diode is directly disposed directly under the display panel to form a direct-lit backlight module instead of the conventional light-emitting diode. The side light type backlight module when the body is a light source. 2. Effectively improve the use of the direct-lit backlight module. When the lamp is used as the light source, the operation will cause the lack of temperature. At the same time, when the conventional side-lit backlight module is used as the light source, the incident angle of the light source is poor. The amount is large and the middle brightness cannot be evenly lost. 3. The multi-directional illuminating light-emitting diode is used as the light source, which can improve the conventional light source with the lack of uniform brightness in the middle, and the light-emitting area emitted by each light-emitting diode is larger and wider. Therefore, the light guide plate of the backlight module can be used without a setup. '4. Since each of the light-emitting diodes can emit 36 degrees of light and cover each other's light, the amount of the light-emitting diode can be greatly reduced, the power consumption is reduced, and the failure rate of the light-emitting diode itself is low. The backlight module is made lighter and thinner, which is more effective in reducing costs and energy. However, the above descriptions are merely preferred embodiments of the present invention, and should not be used to limit the scope of the present invention, and those skilled in the art will be able to devise and modify them. The substance of the invention is removed. In summary, the present invention can achieve the intended purpose of creation, and provides a multi-directional light-emitting diode backlight module, which has practical value, and 提出 legally filed an invention patent application.
