液晶顯示裝置作為一種平面顯示裝置,因其具有輝度高、重量輕及耗電少等優點,而被廣泛應用於各種家用電器及辦公設備中。而因為液晶顯示裝置中之液晶本身不具有發光特性,通常需要為其提供一背光模組以實現顯示功能。As a flat display device, a liquid crystal display device is widely used in various home appliances and office equipment because of its advantages of high brightness, light weight, and low power consumption. Because the liquid crystal in the liquid crystal display device itself does not have the light emitting property, it is generally required to provide a backlight module to realize the display function.
請參閱圖1,係一種先前技術背光模組之立體分解圖。該背光模組12包括一背板13、一反射片14、一導光板15、一膠框16、複數光源17及一擴散片18。該背板13包括四側壁131及一與該四側壁131垂直連接之底板132。該導光板15包括一入光面151、一與該入光面151相鄰之出光面152及一與該出光面152相對之底面(未標示)。該背板13與該膠框16結合形成一收容空間(未標示),該反射片14、該導光板15、該光源17及該擴散片18收容於該收容空間內。其中,該反射片14位於該底板132與該導光板15之底面之間。該光源17鄰近該導光板15之入光面151設置。該擴散片18鄰近該導光板13之出光面152設置。該導光板15之底面上分佈有網點(圖未示),該網點用於擴散該光源17入射至該底面之光線,以使該導光板15均勻發光。Please refer to FIG. 1 , which is an exploded perspective view of a prior art backlight module. The backlight module 12 includes a back plate 13 , a reflective sheet 14 , a light guide plate 15 , a plastic frame 16 , a plurality of light sources 17 , and a diffusion sheet 18 . The back plate 13 includes four side walls 131 and a bottom plate 132 perpendicularly connected to the four side walls 131. The light guide plate 15 includes a light incident surface 151, a light exit surface 152 adjacent to the light incident surface 151, and a bottom surface (not labeled) opposite to the light exit surface 152. The backplane 13 and the plastic frame 16 are combined to form a receiving space (not shown). The reflective sheet 14, the light guide plate 15, the light source 17 and the diffusing film 18 are received in the receiving space. The reflective sheet 14 is located between the bottom plate 132 and the bottom surface of the light guide plate 15.

The mesh is used to diffuse the light incident on the bottom surface of the light source 17 to uniformly illuminate the light guide plate 15.
惟,目前該背光模組12之背板13、膠框16及反射片14通常為相互分離之三部份,故組裝該背光模組12時需要較多之工序,導致該背光模組12之製造成本增加。組裝後之該背板13、膠框16及反射片14因為存在間隙導致該背光模組12之厚度較厚。該背板13通常係金屬材質,而因為金屬之重量通常較重且價格較高,所以造成採用該金屬背板13之該背光模組12之重量較重且其製造成本進一 步提高。The back panel 13 , the plastic frame 16 , and the reflective sheet 14 of the backlight module 12 are generally separated from each other. Therefore, more steps are required to assemble the backlight module 12 , resulting in the backlight module 12 . Manufacturing costs increase. The assembled back panel 13, the plastic frame 16 and the reflective sheet 14 have a thicker thickness of the backlight module 12 due to the presence of a gap. The back plate 13 is usually made of a metal material, and since the weight of the metal is generally heavy and the price is high, the backlight module 12 using the metal back plate 13 is heavy and the manufacturing cost thereof is high. Step up.
有鑑於此,提供一種製造成本較低、厚度較薄及重量較輕之背光模組實為必要。In view of this, it is necessary to provide a backlight module having a lower manufacturing cost, a thinner thickness, and a lighter weight.
有鑑於此,提供一種製造成本較低、厚度較薄及重量較輕之背光模組之製造方法實為必要。In view of this, it is necessary to provide a manufacturing method of a backlight module which is low in manufacturing cost, thin in thickness, and light in weight.

FIG. 5 is an exploded perspective view of the backplane 23 shown in FIG. 3, and FIG. 6 is a schematic diagram of the combination of the backlight module 22 shown in FIG. The manufacturing method of the backlight module 22 includes the following steps:
步驟一:利用分段式加工方法製造該背板23;該背板23係由四第一L形材236及四第二L形材237利用鐳射焊接技術焊接而成。該四第一L形材236分別包括一第一側臂238及與一該第一側臂238垂直連接之第二側臂239。該第一側臂238及該第二側臂239均包括一與該導光板26平行之水平部份(未標示)及一自該水平部份之自由端之端末垂直延伸出來之豎直部份(未標示)。該四第二L形材237包括一第三側臂240及一與該第三側臂240垂直連接之第四側臂241。該第三側臂240及該第四側臂241均包括一與該導光板26平行之水平部份(未標示)及一自該水平部份之外側邊垂直延伸出來之豎直部份(未標示)。Step 1: The backing plate 23 is manufactured by a segmented processing method; the backing plate 23 is formed by welding four first L-shaped materials 236 and four second L-shaped materials 237 by laser welding. The four first L-shaped members 236 respectively include a first side arm 238 and a second side arm 239 perpendicularly connected to the first side arm 238. The first side arm 238 and the second side arm 239 each include a horizontal portion (not labeled) parallel to the light guide plate 26 and a vertical portion extending perpendicularly from the end of the free end of the horizontal portion. (not marked). The four second L-shaped members 237 include a third side arm 240 and a fourth side arm 241 vertically connected to the third side arm 240. The third side arm 240 and the fourth side arm 241 each include a horizontal portion (not labeled) parallel to the light guide plate 26 and a vertical portion extending perpendicularly from the outer side of the horizontal portion ( Not marked).
利用鐳射焊接技術接合時,首先,將該四第一L形材236分成兩組,每一組均包含兩第一L形材236,然後,將每一組之第一L形材236之第二側臂239相焊接固定。故,該四第一L形材236成為二T形材(未標示)。接著,將構成該二T形材之該第一L形材236之第一側臂238相焊接固定,故,該四第一L形材236經過焊接固定後成為一呈“十”字形材。最後,將該四第二L形材237之端部份別與構成該“十”字形材之該第一L形材236之端部焊接固定。如此,帶有該矩形通孔233之該背板23組裝完成。其中,該四第一L形材236之水平部份及該四第二L形材237之水平部份構成該底板231,其垂直部份構成該四側壁232。When joining by laser welding technology, first, the four first L-shaped materials 236 are divided into two groups, each group includes two first L-shaped materials 236, and then, the first L-shaped material 236 of each group is The two side arms 239 are welded and fixed. Therefore, the four first L-shaped members 236 become two T-shaped members (not shown). Next, the first side arm 238 of the first L-shaped material 236 constituting the two T-shaped members is welded and fixed, so that the four first L-shaped members 236 are welded and fixed to form a "ten" shape. Finally, the end portions of the four second L-shaped members 237 are welded and fixed to the end portions of the first L-shaped members 236 constituting the "ten" shaped material. Thus, the backing plate 23 with the rectangular through hole 233 is assembled. The horizontal portion of the four first L-shaped members 236 and the horizontal portion of the four second L-shaped members 237 constitute the bottom plate 231, and the vertical portions thereof constitute the four side walls 232.
步驟二:提供白色之高反射率之聚碳酸酯材料與模具,並將該背板23放置於該模具內,以模內成型之方式結合該背板23、該膠框 24與該反射層25。Step 2: providing a white high reflectivity polycarbonate material and a mold, and placing the back sheet 23 in the mold, and combining the back sheet 23 and the plastic frame in an in-mold forming manner 24 and the reflective layer 25.
要實現步驟二所述之內容,需要對現有技術中注膠成型該膠框14之模具進行改進,使該模具能夠同時注膠成型該膠框24及該反射層25。To implement the content described in the second step, it is necessary to improve the mold for molding the plastic frame 14 in the prior art, so that the mold can simultaneously insert and mold the plastic frame 24 and the reflective layer 25.

步驟五:提供該擴散片27,將該擴散片27放置於該導光板26之出光面262上。Step 5: The diffusion sheet 27 is provided, and the diffusion sheet 27 is placed on the light-emitting surface 262 of the light guide plate 26.
相較於先前技術,本發明背光模組22包括該組合框架29,組裝該背光模組22時,將該組合框架29與其他光學元件進行組裝即可。故,組裝該背光模組22所需之工序減少,使得該背光模組22之製造成本降低。而該膠框24及該反射層25為同時注膠成型且與該背板23結合為一體,故,組裝後之該背光模組22之厚度較薄。該背板23之底板231設置有通孔233,注膠成型該反射層25所需之材料聚碳酸酯填滿該通孔233。根據該背光模組22尺寸之不同,相應合理之設計該通孔233之大小,則該背板23與其通孔233內之聚碳酸酯材料能夠保證該背光模組22之結構強度要求。而一般的,相同體積之聚碳酸酯材料之重量輕於金屬鋁之重量,且聚碳酸酯材料之成本低於金屬鋁之成本,故,採用與該反射層25結合為一體之背板23之背光模組22重量較輕,且該背光模組22之製造成本進一步降低。Compared with the prior art, the backlight module 22 of the present invention includes the combined frame 29, and when the backlight module 22 is assembled, the combined frame 29 can be assembled with other optical components. Therefore, the process required for assembling the backlight module 22 is reduced, so that the manufacturing cost of the backlight module 22 is reduced. The plastic frame 24 and the reflective layer 25 are simultaneously injection molded and integrated with the back plate 23, so that the assembled backlight module 22 has a thin thickness. The bottom plate 231 of the back plate 23 is provided with a through hole 233 through which the material polycarbonate required for molding the reflective layer 25 fills. According to the size of the backlight module 22, the size of the through hole 233 is correspondingly designed, and the polycarbonate material in the back plate 23 and the through hole 233 can ensure the structural strength requirement of the backlight module 22. Generally, the weight of the same volume of polycarbonate material is lighter than the weight of the metal aluminum, and the cost of the polycarbonate material is lower than the cost of the metal aluminum. Therefore, the backing plate 23 integrated with the reflective layer 25 is used. The backlight module 22 is light in weight, and the manufacturing cost of the backlight module 22 is further reduced.
