The conventional backlight module design, as shown in the third figure, is mainly provided with a frame (6 i) on the periphery of a light guide plate (6 〇), and a lamp cover (62) is installed in the frame (6 i). And a light-emitting component (63) (such as a cold cathode lamp or the like) located in the lampshade (62), the light-emitting component (63) adjacent to the light-incident surface of the light guide plate (60) (6 〇丄Thereby, the light emitted by the light-emitting component (63) can be incident from the light-incident surface (6〇1) of the light-guiding plate (6〇) into the light-receiving plate (60) and continuously reflected from the top thereof. The light-emitting surface (6 〇 2) is scattered and transmitted through the optical film (not shown) on the upper surface to homogenize the light to provide a uniform light source for the liquid crystal panel. In the structure of the backlight module described above, the side end of the light guide plate (6〇) is made to be occupied by the double-sided tape (6 4 ) I in order to further integrate the frame (6丄) with the light guide plate (60). The outer edge of the lamp top inside the frame (6 1 ).

Therefore, under the shape of the vertical end edge 200919012, the position of the light guide plate and the lampshade inside the frame is too short, and is easily loosened by the vibration. Therefore, the main purpose of the present invention is to provide a backlight module having the function of improving the space utilization of the frame space, thereby designing and improving the backlight. The overlap between the frame and the light guide plate in the module is too short. To achieve the above purpose, the cup of the present invention: ^4_々北,, + I 3 sighs the backlight module includes: - a border, a light cover is disposed in the frame, a light emitting component is disposed in the light cover, and a light guide plate is disposed at an inner circumference of the frame, the light guide plate has a light emitting surface on the top surface, and a soil zk μ is reduced. J light entrance is located at the side The light-incident surface is adjacent to the light-emitting component, wherein the light-guiding plate has at least one overlapping portion protruding from the periphery of the light-emitting surface toward the outer side of the human light surface, and the overlapping portion extends into the light cover and is located at the light-emitting surface The top of the light-emitting component is provided with the top of the lamp cover and the top frame of the frame. The present invention is characterized in that the light-guiding plate has at least a lap joint from the periphery of the light-emitting surface. The light-emitting surface is convex toward the outer side, so that the light-guiding plate is disposed at the inner circumference of the frame, and the overlapping portion can extend into the lamp cover in the frame and is located above the light-emitting component, so as to be in the existing backlight module. Under the specification of the specification and size, and the change of the shape: the state in which the light component is incident on the light guide plate, the lap joint portion of the lampshade and the top frame portion of the frame are combined for a larger area. The combination of the backlight module is too short and the connection between the frame and the light guide plate is too short, and the internal space of the frame is improved. 200919012 The bottom surface and the adjacent step are thick to avoid the hair. The purpose of the person is to further form a β _ arc surface between the illuminating surfaces of the lap, and the curved surface enters the _ rough surface so that the light projecting the rough curved surface can be scattered to produce a bright line. Another secondary object of the present invention is further solidified by a double-sided tape or other adhesive. [Embodiment] The joint between the lap portion and the top of the lampshade is fixed to make the two more stable...
