New Description: [New Technology Field] This creation is related to a backlight module, and in particular to an edge-lit backlight module. [Prior Art] The backlight module is one of the key components of the liquid crystal display. Since the liquid crystal itself does not emit light, the function of the backlight module is to provide a sufficient light source with uniform brightness and uniformity, so that the liquid crystal panel can display images normally. The backlight module is disposed on the back surface of the liquid crystal panel to provide a uniformly dispersed light onto the liquid crystal panel, so that the image formed by controlling the primitive electrode on the liquid crystal panel is uniformly illuminated to obtain a display. The backlight module can be divided into a direct type backlight module in which the incident light source is located behind the back side of the display panel according to the position of the light source, and an edge light type backlight module in which the incident light source is located near one side of the display panel. In general, the backlight module of the edge-light structure has the characteristics of light weight, thin shape, narrow frame, low energy consumption, and is suitable for notebook computers and liquid crystal display products of 14 inches or less; and the backlight module of the direct type structure Due to its high brightness, it is more suitable for products with large size LCD heads. The conventional edge-lit backlight module includes a frame, a light guide plate, a light source disposed on one side of the light guide plate, a reflective cover disposed outside the light source, a reflector disposed under the light guide plate and fixed to the frame, and a reflector a diffusion plate between the light guide plate and the display panel. Wherein, the light source is a light source generator (commonly used cold cathode fluorescent tube CCFL or high brightness light emitting diode 4 M339699 polar body LED), and the light emitted by the light source is usually incident from the side of the light guide plate into the light guide plate, the reflection cover and the reflection The plate is used for re-introducing the unscattered light into the light guide plate to increase the utilization of the light. The light guide plate is used to scatter the light emitted by the light source onto the diffusion plate, and the diffusion plate diffuses the light to spread evenly, eliminating the light guide plate. The bright area formed by the upper microstructure realizes uniform illumination, and the frame is used to fix the light guide plate, the light source generator, the reflection cover, the reflection plate and the diffusion plate. In some configurations, at least one cymbal is further disposed above the diffuser plate to further correct the difference in illumination intensity so that the light received by the liquid crystal panel can have a higher luminance. The light guide plate is embedded in the frame, and is configured to prevent the lamp holder on one side of the frame from being broken by the impact of the light guide plate. Therefore, at least one lug is disposed on one edge of the light guide plate, and a position corresponding to the lug is disposed on the frame. Positioning groove for embedding and fixing the light guide plate. Since the backlight module generates heat during use, the components such as the light guide plate may expand and contract, and in order to avoid the occurrence of cracking in the groove of the frame during use, in the conventional structure, there is a certain relationship between the positioning groove and the lug. The gap is; however, the problem with this is that during the handling of the finished product, or in the opening and closing of the notebook display, there will be a back-and-forth collision between the light guide plate and the frame, and an abnormal sound is emitted, especially The phenomenon that the lug is released from the groove will directly affect the quality of the finished product and normal use. [New content] One of the purposes of this creation is to provide a backlight module structure, and M339699 stable m holding light guide. 4 to the above object, a side light L two-module structure according to a preferred embodiment of the present invention comprises: a frame, a light guide plate, and a light source disposed on the light guide 2, at least one side edge of the light guide plate There is at least one convex ~ ~, the frame corresponding to the lug structure is provided with a positioning groove, each of the two positions = the inner wall of the groove is connected with an elastic structure, and the elastic structure is positioned in the concave concave portion and the female one lug structure is received. In a corresponding positioning groove, the elastic structure abuts the lug structure.
