When the position of the substrate assembled to the lamp cover is wrong, we can force the substrate to be easily pulled out from the lamp cover while maintaining the substrate. Integrity. Therefore, in the step of rework, the situation of component damage can be reduced', thereby effectively reducing the overall cost. To make the above and other objects, features and advantages of the present invention more apparent, the following is to be implemented. For example, the following is a detailed description of the following: 1354165 95116 21125 twf.doc/e [Embodiment] First Embodiment FIG. 2 is a schematic view of a display device according to a first embodiment of the present invention. The display device 400 includes a display panel 300 and a backlight module 200. The display panel 300 is a liquid crystal display panel, and the backlight module 200 can be used for one side of the light. The display device 400 of the present embodiment is, for example, a notebook computer. FIG. 3A is a partial perspective view of the backlight module according to the first embodiment of the present invention, and FIG. 3B is a view. 3A is a front view of the backlight module, and FIG. 4 is a cross-sectional view of the backlight module of FIG. 3A. Referring to FIG. 3A, FIG. 3B and FIG. 4, the backlight module 200 of the embodiment includes a substrate 210 and a plurality of light sources. 220 and a lamp cover 230. In this embodiment, the substrate 21 is an elongated printed circuit board. The light source 220 is disposed on the substrate 210, and a gap s is formed between two adjacent light sources 220. The light source 220 of the present embodiment is a light-emitting diode. The light-emitting diode 230 includes a body 232 and a plurality of positioning structures 234. The positioning structure 234 is connected to the body 232, and the positioning structure 234 of the embodiment is the same as the body 232. In a simple manner, the positioning structure 234 is formed by the body 232 of the bent portion. The + body 232 has a recess 232a, wherein the substrate 210 is located in the recess 232a. The positioning structure 234 is correspondingly disposed in the gap. s and bear against the substrate 21〇 to make the substrate 2 1〇 can be firmly fixed to the lamp cover 23〇. In addition, in order to reduce the manufacturing cost, we can also selectively form the positioning structure 234' at the appropriate position of the body 232 without having to have each positioning structure 234 with s It is provided in its 9 1354165 95116 21125 twf.doc/e. In detail, each of the positioning structures 234 has a first extension 234a and a second extension 234b, wherein the first extension 234a is connected to the body 232' The first extension portion 234b is adjacent to the first extension portion 234a. The positioning structure 234 of the present embodiment is an L-shaped rice piece, so that the second extending portion 234b of the positioning structure 234 is substantially perpendicular to the first extending portion 234a. In the present embodiment, the second extension 234b of the positioning structure 234 bears against the substrate 210' to enable the substrate 210 to be stably positioned within the recess 232a of the globe 230. It should be noted that since the second extension portion 234b of the positioning structure 234 of the present embodiment is to position the substrate 21〇 in the groove 232a by means of bearing, the right assembly position of the substrate 210 is wrong, and we can apply The substrate 210 is easily pulled out from the inside of the recess 232a, and the substrate 21 is not damaged. Compared with the prior art, the backlight module 200 of the display device 4 of the present embodiment has the advantages of being easy to rework due to the easy-to-plug substrate 210, and can effectively reduce the overall cost. . In addition, the first extension portion 234b bears against the substrate 21〇, so the heat generated by the illumination of the light source 220 is not only radiated downward by the substrate 210 to the frame of the backlight module 2 (not shown). The heat dissipation method of the backlight module 200 of the present embodiment is more conventional than that of the conventional backlight module, and the heat dissipation effect is better: The width of the second extension portion 234b is smaller than the gap S of the two adjacent light sources 220, preferably just s, to achieve a tight fit of the structure. In addition, in order not to cause the second extension portion 234b to affect the illumination 1354165 95116 21125 twf.doc/e efficiency of the light source 22 〇°, the terminal end of the second extension portion 234b may be recessed within the illumination surface of the light source 220, or just It is flush with the luminous surface. In particular, in order to reduce the external size of the display device 400, we can also reduce the length of the second extension portion 234b. In other words, the distance d between the first extension portion 234a and the light source 220 is shortened. In addition, in order to improve the light use efficiency of the display device 400, a light guide plate 240 may be disposed on one side of the lamp cover 230. The backlight module 200 of the embodiment is a one-side light-integrating backlight module, and the light guide plate 240 is disposed adjacent to the lamp cover 230 and located under the display panel 300, as shown in FIG. In another embodiment not shown, the backlight module 200 is a direct type backlight module, and the light guide plate 240 is replaced by a diffusion plate (not shown) and the diffusion plate is disposed between the lamp cover 230 and the display panel 300. Further, in order to enhance the display effect of the display device 400, an optical film 310 may be disposed between the display panel 300 and the backlight module 200. The optical film 310 of this embodiment may be a diffuser plate, a polarizer, a prism sheet or a combination of these films. Second Embodiment FIG. 5 is a perspective view of a backlight module according to a second embodiment of the present invention, and FIG. 6 is a cross-sectional view of the backlight module of FIG. 5. In FIG. 5, FIG. 6 and FIG. 3, FIG. 4, the same or similar component numbers denote the same or similar elements, and the present embodiment is substantially the same as the first embodiment. Therefore, the following only differs between the two embodiments. Explain in detail that 'the same thing will not be repeated. Referring to FIG. 5 and FIG. 6 simultaneously, the first embodiment is different from the first embodiment. In the present embodiment, the positioning structure 234 of the backlight module 200 is formed by using the stamping body 232'. The protrusions 'and the protrusions are convex toward the substrate 210. In detail, the positioning structure 234 has a first extending portion 234a and a second extending portion 234b', wherein the first extending portion 234a is connected to the body 232"' and the second extending portion 234b' is adjacent to the first extending portion. Part 234a. The positioning structure 234' of the present embodiment is a protrusion of the convex substrate 210, and the second extending portion 234b' of the positioning structure 234' is substantially perpendicular to the first extending portion 234a. In this embodiment, the second extending portion 234b protruding from the substrate 210 bears against the substrate 210'. Therefore, the lamp cover 230' utilizes the body 234' and the second extending portion 234b to hold the substrate 210' to enable the substrate 210 to be stably Located in the groove 232a, inside. In addition, in order to save manufacturing costs, we can also selectively press at the appropriate position of the body 232' to form the positioning structure 234, and it is not necessary for each of the gaps S to have the positioning structure 234' disposed therein. Since the lamp cover 230 of the present embodiment utilizes the second extension portion 234b, and the body 232' holds the substrate 210, the substrate 210 is positioned within the recess 232a. Therefore, when the assembly position of the substrate 210 is wrong, we can force the substrate 210 to be easily pulled out from the recess 232a' without causing damage to the substrate 21. Compared with the conventional one, the substrate 21 is easily pulled out from the backlight module 200' during rework, which can reduce the damage of parts during rework, thereby effectively reducing the overall cost. Since the positioning structure 234 of the embodiment is not disconnected from the body 232', the heat generated by the light source 220 of the embodiment can be generated by the frame of the backlight module 200 (not shown) and the The second extension portion 234b can be radiated to the main body 232 through the second extension portion 234b to dissipate heat over a large area, so that the backlight module 2 of the embodiment is The heat dissipation effect is better than that of the backlight module 200 of the first embodiment. Similarly, the width of the second extension portion 234b is smaller than the gap width of the two adjacent lamps 220, preferably just the width of the gap, to achieve a tight fit of the structure. Further, in order not to affect the luminous efficiency of the light source 22A without the second extending portion 234b, the terminal end of the second extending portion 234b may be recessed within the light emitting surface of the light source 220 or just in line with the light emitting surface. In particular, in order to reduce the size of the display device, we can also reduce the length of the second extension portion 234b. In other words, the distance d between the first extension portion 234a' and the light source 220 is shortened. As described above, the backlight module of the present invention and the display device using the same use the second extension of the positioning structure and the body to hold the substrate, so that the substrate can be stably positioned in the recess of the lamp cover. In addition, when the position of the substrate assembly to the lamp cover is wrong, we can force the substrate to be easily pulled out from the lamp cover while maintaining the integrity of the substrate. In addition, in the step of rework, the integrity of the substrate can be maintained, so that 70 pieces of damage due to heavy work can be reduced, thereby effectively reducing the overall cost. Moreover, the second extension portion bears against the substrate, so that the backlight module has more heat dissipation paths and better heat dissipation effect. In addition, we can also reduce the size of the display device by reducing the length of the first extension. </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> </ RTI> <RTIgt; Retouching, as 13 1354165 95116 21125 twf.doc/e The scope of protection of the present invention is defined by the scope of the appended claims.
