New Description: [New Technology Field] This creation is about a kind of edge-lit backlight module, especially the edge-lit backlight module with fixed lugs and positioning slots. [Prior Art] φ #光模块 (back off tunit) is one of the key components of liquid crystal display (LCD), because the liquid crystal panel (LCDpand) itself has the ability to emit light. Supply sufficient brightness and distribution (10) light source, f liquid crystal display can display images normally. At present, liquid crystal displays have been widely used in electronic products with growth potential such as monitors, notebook computers, digital cameras and downtime machines, so the demand for backlight modules and related components continues to grow. Due to its small size, long life, low power consumption, short reaction time and strong shock resistance, LEDs have been widely used in _ or Weiyuan to replace traditional tungsten bulbs, fluorescent tubes or cold cathodes.

A reflecting plate % is disposed, and a light cover #% is disposed between the sending member 442 and the second extending portion 422, which is a kind of reflector negatively directed to the light cover piece 52 or the flat spear counter 461 light in the reflecting plate 50 or the lamp cover After the surface of the sheet 52 is reflected, it turns into the light incident surface of the light guide plate 48 to improve the light source utilization rate. In addition, a heat-dissipating glue 54 may be attached to the back of the light bar 44 to help the light-emitting element 442 to dissipate heat. π Since the heat-dissipating glue between the light bar 44 and the upright portion 462 is a soft substance and has a bullet=, in addition to filling the light bar 44 The gap between the erecting portion 462 and the erecting portion 462 is used as a buffer for both the heat sink and the assembly. M366096, knowing that the 'creation system provides a side-light type odd-light module that can fix the distance between the light strip and the light guide plate', in the assembly, the fixing lugs on both sides of the substrate using the light strip are respectively determined by t The positioning of the recording groove or the back plate (four), so that the light-emitting elements on the wire and the light guide plate can be maintained at an appropriate distance; in addition, the positioning recess provided on the back plate is not limited to being disposed on the flat plate The bottom of the back plate accommodates the bottom of the slot to assist in fixing the light bar; in addition, the heat-dissipating glue disposed on the light bar and the back can provide the remaining efficiency of the #纽纽, and can also be used as a light bar and a back plate. The buffer is used to improve the reliability of the backlight module. At the same time, the backlight module of the present invention is excellent in assembly, and the light strip can be removed from the backboard or the frame if needed during assembly. Reduce the defect rate of the product. The above descriptions are only preferred embodiments of the present invention, and all changes and modifications made in accordance with the scope of patent application of this creation should be covered by this creation. [Simple description of the drawing] _ Figure 1 shows the conventional side-lit backlight module. 2 to 4 are schematic views of a backlight module according to a preferred embodiment of the present invention. 5 to 8 are schematic views of a backlight module according to another preferred embodiment of the present invention.
