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 to maintain the integrity of the substrate. Therefore, in the step of rework, the month b is enough to reduce the damage of the piece, thereby effectively reducing the overall cost. The above and other objects, features, and advantages of the present invention will become more apparent from the following description. 200829999 95116 21125 twf.doc/e [Embodiment] First Embodiment FIG. 2 is a schematic diagram of a display device according to a first embodiment of the present invention. Please refer to FIG. 2 , the display device 400 includes a display panel 3 〇〇 and a backlight module 200 , wherein the display panel 300 is a liquid crystal display panel, and the backlight module 200 can be a side-lit optical backlight module or straight down. Backlight module. The display device 400 of this embodiment is, for example, a notebook computer (N〇te B〇〇k). 3A is a partial perspective view of a backlight module according to a first embodiment of the present invention, FIG. 3B is a front view of the backlight module of FIG. 3A, 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 optical module 200 of the present embodiment includes a substrate 210, a plurality of light sources 220, and a light cover 230. In the present 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, and the light source 22 of the embodiment is a light emitting diode. In the above, the lamp cover 230 includes a body 232 and a plurality of positioning structures 234', wherein the positioning structure 234 is coupled to the body 232, and the positioning structure 234 of the embodiment is integrally formed with the body 232. Briefly, the positioning structure 234 is formed by bending the body 232 of the portion. The body 232 has a recess 232a in which the substrate 210 is located within the recess. The positioning structure 234 is disposed corresponding to the gap s and bears against the substrate 21A so that the substrate can be stably fixed to the material 23G. 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. It is not necessary to make each gap s find the structure in its 200829999 95116 21125twf.doc/e. In detail, each of the positioning structures 234 has a first extending portion 234a and a second extending portion 234b, wherein the first extending portion 234a is coupled to the body 232, and the second extending portion 234b is adjacent to the first extending portion 234a. The positioning structure 234 of the present embodiment is an L-shaped member, so that the second extending portion 234b of the positioning structure 234 is substantially perpendicular to the first extending portion 234a. In this embodiment, the second extension portion 234b of the positioning structure 234 bears against the substrate 210 to enable the substrate 210 to be stably positioned in the recess 232a of the lamp cover 230. It is noted that the positioning of the embodiment is due to this embodiment. The second extending portion 234b of the structure 234 is configured to position the substrate 210 in the recess 232a by means of bearing. Therefore, if the position of the substrate 210 is wrong, we can force the substrate 210 to be easily pulled out from the recess 232a. 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 21, and can effectively reduce the overall efficiency. cost. In addition, the second extension portion 234b bears against the substrate 21A. Therefore, the heat generated by the illumination of the light source 220 is transmitted to the backlight module 2 through the substrate 21, and the frame (not shown) is cooled downward. In addition, the heat dissipation path of the backlight module 200 of the present embodiment is more conventional than that of the conventional backlight module, and the second extension portion is notable. 234b_f is 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 make the second extension portion 234b affect the luminous efficiency of the light source 22〇, the terminal end of the second extension portion 234b may be recessed within the light emitting surface of the light source 220, or just The luminous surface is aligned. In particular, in order to reduce the size of the display device 400, we can also reduce the length of the 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 moonlight power group 200 of the embodiment is a one-side light-input backlight module, and the light guide plate 240 is disposed beside the lamp cover 230 and located under the display panel 3, as shown in FIG. In another embodiment, 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. In addition, in order to suppress the display effect of the display device 400, an optical film 31A can be disposed between the display panel 300 and the backlight module 2A. The optical film 310 of this embodiment may be a diffusm plate, a polarizer, a ruthenium (prism such as ruthenium or a combination of these films. The second embodiment 5 is a second embodiment of the present invention. 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 components, and the present embodiment The example is substantially the same as the first embodiment, so the following is only for the differences of the two embodiments, and the same points will not be described again. 凊 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 a protrusion formed by the stamping body 232', and the protrusion is convex toward the substrate 210. In detail, positioning The 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 234a. The positioning structure 234' is a convex substrate 210 The second extension 234b' of the positioning structure 234' is substantially perpendicular to the first extension 234a. In this embodiment, the second extension 234b protruding toward the substrate 210 will bear against the substrate 210, thus the lampshade 230' is a body 234, and a second extension portion 234b, holding the substrate 210, so that the substrate 210 can be stably positioned in the groove 232a. In addition, in order to save manufacturing costs, we can also selectively in the body 232' Pressing the appropriate position to form the positioning structure 234, and not necessarily each of the gaps S must have a positioning structure 234, which is disposed therein. Since the lamp cover 230 of the embodiment utilizes the second extending portion 234b, and the body The substrate 210 is held 232 to position the substrate 210 in 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 The substrate 210 is damaged. 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. It The bit structure 234 is not disconnected from the body 232. Therefore, the heat generated by the light source 220 of the embodiment can be generated by the frame (not shown) and the second extending portion 234b of the moonlight module 200 at the same time. In addition to the heat dissipation of the upper 12 200829999 95116 21125 twf.doc/e and the lower heat dissipation, the second extension portion 234b can be transmitted to the main body 232 to dissipate heat over a large area. Therefore, the backlight module of the embodiment is cooled. The effect is better than the backlight module 200 of the first embodiment.
同樣地，第二延伸部234b，的寬度為小於兩相鄰之燈 源220的間隙寬度，較佳為剛好是間隙的寬度，以達到結 構的緊配。此外，為了不使第二延伸部234b，影響燈源 的發光效率，因此第二延伸部234b，的終端可以凹陷於燈 源220的發光面之内，或是剛好與發光面切齊。 特別的是，為了縮小顯示裝置的外觀尺寸，我們也可 以減少第二延伸部234b，的長度。換言之，即是縮短第一 延伸部234a，與光源220之間的距離d。 壯，上所述，本發明背光模組及使用此背光模組之顯示 衣置是利用定位結構的第二延伸部以及本體挾持基板，因 ，基=能夠穩固地定位於燈罩的凹槽内。此外，當基板組 =至k罩的位置錯誤時，我們可以施力將基板從燈罩中_ 易地拔出，同時並可以保持基板的完整性。另外，在重: 的步驟中，能夠保持基板的完整性，因此可以減少因重工 使元件損壞的情形，進而有效地降低整體成本。 徑^外’ ί二延伸部承#於基板，讓f光漁的散熱途 -且政熱效果較佳。此外，我們也可以藉由減少第 雖邛的長度’以達到縮小顯示裝置之外觀尺寸的目的。 定本择^本發明已以—實施例揭露如上，然其並非用以限 離本發明之中tr常知識者，在不脫 狎和乾圍内，當可作些許之更動與潤飾，因 13 200829999 95116 21125twf.doc/e 此本發明之保護範圍當視後附之申請專利範圍所界定者為 準。 【圖式簡單說明】 圖1為習知一種背光模組的示意圖。 圖2為本發明第一實施例之顯示裝置的示意圖。 圖3A為本發明第一實施例之背光模組的局部立 圖3B為圖3A之背光模組的前視圖。 西 _ 圖4為圖3A之背光模組的剖視圖。 圖5為本發明第二實施例之背光模組的局部立 圖6為圖5之背光模組的剖視圖。 —圖。 【主要元件符號說明】 100、200、2〇0,：背光模組 110 :光源 112 :發光二極體 114 ·印刷電路板 120 :雙面膠 Φ 130 :燈罩 210 :基板 220 :燈源 230 :燈罩 232、232’ ：本體 232a、232a，：凹槽 234、234,：定位結構 234a、234a’ ：第一延伸部 200829999 95116 21125twf.doc/e 234b、234b’ ：第二延伸部 240 :導光板 300 :顯示面板 310 :光學膜片 400 :顯示裝置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 to prevent the second extending portion 234b from affecting the luminous efficiency of the light source, 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 backlight module utilize the second extension portion of the positioning structure and the body holding substrate, because the base = can be stably positioned in the recess of the lamp cover. In addition, when the position of the substrate group = to the k 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 weighing: the integrity of the substrate can be maintained, so that the damage of the component due to heavy work can be reduced, thereby effectively reducing the overall cost. The diameter of the outer ^ ί two extension part of the # on the substrate, let f light fishing heat dissipation - and the political heat effect is better. In addition, we can also reduce the size of the display device by reducing the length of the first frame. The present invention has been disclosed in the above embodiments, but it is not intended to limit the knowledge of the present invention. In the absence of dislocation and dryness, when some changes and refinements can be made, 13 200829999 95116 21125 twf.doc/e The scope of the invention is defined by the scope of the appended claims.
