在上述配置方式之下,背光模組100利用夾持結構142來夾持光學膜片120的端部120a,並利用彈性件144的彈性力使夾持結構142施加拉力於光學膜片120,以藉此拉力將光學膜片120拉伸為平整的狀態而不會彎曲變形,故不需額外配置擴散板來支撐光學膜片120,進而節省背光模組100的製造成本及組裝工序。此外,本實施例的光學膜片120例如是包含複合材料的膜片而具有擴散光線的效果,以取代傳統背光模組之擴散板的作用。在其他實施例中,光學膜片的數量可為多個且其中包含擴散片, 本發明不對此加以限制。 In the above configuration, the backlight module 100 uses the clamping structure 142 to clamp the end portion 120a of the optical film 120, and utilizes the elastic force of the elastic member 144 to apply the tensile force to the optical film 120 to Thereby, the optical film 120 is stretched into a flat state without bending deformation, so that the diffusion plate is not required to support the optical film 120, thereby saving the manufacturing cost and assembly process of the backlight module 100. In addition, the optical film 120 of the present embodiment is, for example, a film containing a composite material and has the effect of diffusing light to replace the function of the diffusion plate of the conventional backlight module. In other embodiments, the number of optical films may be multiple and include a diffusion sheet therein. The invention is not limited thereto.
在本實施例中,各夾持結構142包括兩夾持部142a、142b,兩夾持部142a、142b分別接觸光學膜片120之端部120a的相對兩表面而夾持端部120a,各彈性件144如圖1所示被壓縮於夾持部142a與背板110的側板114之間。詳細而言,背板110之各側板114具有一承載部114a及連接於承載部114a的一止擋部114b,承載部114a承載夾持結構142及彈性件144,各彈性件144被壓縮於止擋部114b與夾持結構142的夾持部142a之間。在本實施例中,止擋部114b例如是彎折地連接於承載部114a,然本發明不以此為限,止擋部可藉由其他適當方式形成於承載部上,而非藉由彎折方式形成。 In this embodiment, each of the clamping structures 142 includes two clamping portions 142a, 142b. The two clamping portions 142a, 142b respectively contact the opposite surfaces of the end portions 120a of the optical film 120 to clamp the end portions 120a. The member 144 is compressed between the clamping portion 142a and the side plate 114 of the backing plate 110 as shown in FIG. In detail, each side plate 114 of the back plate 110 has a bearing portion 114a and a stopping portion 114b connected to the carrying portion 114a. The carrying portion 114a carries the clamping structure 142 and the elastic member 144, and the elastic members 144 are compressed. The blocking portion 114b is interposed between the blocking portion 142a of the clamping structure 142. In this embodiment, the stopping portion 114b is connected to the bearing portion 114a, for example, in a bent manner. However, the present invention is not limited thereto, and the stopping portion can be formed on the bearing portion by other suitable means instead of bending. The folding method is formed.
請參考圖1,光學膜片120具有一出光面122,各彈性件144例如是沿平行於出光面122的方向D1被壓縮於對應的夾持結構142與背板110的側板114之間,以使夾持結構142沿平行於出光面122的方向D1施加拉力於光學膜片120。據此,光學膜片120可確實地藉由這些夾持結構142所施加的拉力而維持於平整不彎曲的狀態。 Referring to FIG. 1 , the optical film 120 has a light-emitting surface 122 . The elastic members 144 are compressed between the corresponding clamping structure 142 and the side plate 114 of the back plate 110 , for example, in a direction D1 parallel to the light-emitting surface 122 . The clamping structure 142 is applied to the optical film 120 in a direction D1 parallel to the light exit surface 122. Accordingly, the optical film 120 can be surely maintained in a flat, unbent state by the tensile force applied by the clamping structures 142.
本實施例的各夾持組件140更包括一鎖附件146,用以沿垂直於出光面122的方向D2將夾持結構142鎖附於背板110的承載部114a。具體而言,背板110之承載部114a上具有一開孔114c,各夾持部142a、142b具有一鎖附孔H,鎖附件146穿過開孔114c並鎖附於兩夾持部142a、142b的兩鎖附孔H而提供鎖附力,使夾 持結構142藉由此鎖附力而施加夾持力於光學膜片120。在本實施例中,開孔114c的孔徑d1大於鎖附件146的外徑d2,以提供鎖附件146及夾持結構沿方向D1移動的空間,使被鎖附件146鎖附的夾持結構142能夠藉由彈性件144的彈性變形能力而相應地產生位移以確實地沿方向D1施加拉力於光學膜片120。 Each of the clamping assemblies 140 of the present embodiment further includes a lock attachment 146 for locking the clamping structure 142 to the carrying portion 114a of the backing plate 110 in a direction D2 perpendicular to the light exiting surface 122. Specifically, the carrying portion 114a of the back plate 110 has an opening 114c. Each of the clamping portions 142a, 142b has a locking hole H. The locking attachment 146 passes through the opening 114c and is locked to the two clamping portions 142a. The two locks of the 142b are attached to the hole H to provide a locking force, so that the clip The holding structure 142 applies a clamping force to the optical film 120 by the locking force. In the present embodiment, the aperture d1 of the opening 114c is larger than the outer diameter d2 of the lock attachment 146 to provide a space for the lock attachment 146 and the clamping structure to move in the direction D1, so that the clamping structure 142 locked by the lock attachment 146 can The displacement is correspondingly generated by the elastic deformability of the elastic member 144 to surely apply a tensile force to the optical film 120 in the direction D1.
圖3繪示圖1的鎖附件未鎖附於夾持結構。在本實施例中,當鎖附件146未鎖附於兩夾持部142a、142b時,兩夾持部142a、142b之間的距離如圖3所示大於光學膜片120的厚度,以使光學膜片120的端部120a能夠順利地伸入夾持結構142。當鎖附件146如圖1所示鎖附於兩夾持部142a、142b時,兩夾持部142a、142b之間的距離藉由鎖附力而縮小以使夾持結構142夾持光學膜片120的端部120a。 FIG. 3 illustrates the lock attachment of FIG. 1 not being locked to the clamping structure. In the present embodiment, when the lock attachment 146 is not locked to the two clamping portions 142a, 142b, the distance between the two clamping portions 142a, 142b is greater than the thickness of the optical film 120 as shown in FIG. The end 120a of the diaphragm 120 can smoothly extend into the clamping structure 142. When the lock attachment 146 is locked to the two clamping portions 142a, 142b as shown in FIG. 1, the distance between the two clamping portions 142a, 142b is reduced by the locking force to cause the clamping structure 142 to clamp the optical film.

綜上所述,本發明的實施例至少具有以下其中一個優點或功效。本發明的背光模組利用夾持結構來夾持光學膜片的端部,並利用彈性件的彈性力使夾持結構施加拉力於光學膜片,以藉此拉力將光學膜片拉伸為平整的狀態而不會彎曲變形,故不需額外配置擴散板來支撐光學膜片,進而節省背光模組的製造成本及組裝工序。此外,可將背板之開孔的孔徑設計為大於鎖附件的外徑,以提供鎖附件移動的空間,使被鎖附件鎖附的夾持結構能夠藉由彈性件的彈性變形能力而相應地產生位移以確實地施加拉力於光學膜片。 In summary, embodiments of the present invention have at least one of the following advantages or benefits. The backlight module of the present invention uses the clamping structure to clamp the end of the optical film, and utilizes the elastic force of the elastic member to apply a tensile force to the optical film to thereby stretch the optical film to a flattening force. The state is not bent and deformed, so that an additional diffusion plate is not required to support the optical film, thereby saving the manufacturing cost and assembly process of the backlight module. In addition, the aperture of the opening of the backboard can be designed to be larger than the outer diameter of the lock attachment to provide a space for the lock attachment to move, so that the clamp structure locked by the lock attachment can be elastically deformed by the elastic member. A displacement is generated to positively apply a pulling force to the optical film.
