[Prior Art 3 [0002] Today, electronic devices such as mobile phones, video cameras, cameras, game consoles, watches, music players, display screens, digital photo frames, and the like are often provided with screens for displaying usage information. Since the screen itself is not a illuminating display component, the backlight module is required to provide the light source required for display. When assembling the screen, the metal frame, the display panel and the backlight module (Backlight Module) are usually combined to complete the display of the display screen. [〇〇〇3] Traditionally, the screen assembly process is to first backlight the module. The group is combined on a plastic frame, and then the display panel is stacked on the backlight module, and finally the metal bottom frame is placed outside the plastic frame of the backlight module, and is completed by interlocking the metal bottom frame and the plastic frame. Assembly of display panel and backlight module. In the above structure, the light source of the backlight module is fixed inside the plastic frame, so that the heat generated when the light source emits light is transmitted to the metal frame through the plastic frame and finally escapes to the outside through the metal bottom frame. However, since the Light Emitting Diode (LED) has the advantages of low energy consumption, power saving, long service life, small size, and fast response, the backlight module has gradually adopted LED as a light source. However, the LED has a high heat generation and is easily affected by high temperature to reduce the service life and lighting effect, so its heat dissipation efficiency is more important; for this reason, how to improve the heat dissipation effect of the backlight module 1013180028-0, that is, the research of the creator motivation. 1012_f单单删1 Page 3/20 pages M434230 May 11, 2011 Nuclear replacement page [0005] In view of this, the creator has devoted himself to the above objectives, and has devoted himself to the use of academic theory. Finally, I proposed a creation that is based on the above deficiency. [New Content] [0006] One of the purposes of this creation is to provide a backlight module to complete the assembly of a backlight module having a good heat dissipation effect. Another object of the present invention is to provide a backlight module that avoids displacement or plating loss of an optical component due to collision or foreign object impact during transportation. # [0008] In order to achieve the above purpose, the present invention is a backlight module comprising a base, an optical film set, a positioning frame and a light source, the base comprises a bottom plate and a plurality of side plates adjacent to the bottom plate, and the optical film set is disposed at On the bottom plate, the positioning frame comprises a pressing plate for pressing the optical film group and a plurality of positioning plates adjacent to the pressing plate, the light source is disposed on the inner wall surface of one of the side plates, and corresponds to the inner side of one of the positioning plates, and the other side plates are At least one is located outside of at least one of the other positioning plates. [0009] A further object of the present invention is to provide a backlight module, wherein the thermal conductivity of the side plate is higher than the thermal conductivity of the positioning plate, so that the heat generated by the light source can be quickly transmitted to the side plate, and then the heat conduction through the side plate Move to the side panel or the positioning plate to improve heat dissipation efficiency. [0010] Another object of the present invention is to provide a backlight module, wherein the card slot of the side plate is disposed on the lug, and the lug can be partially bent toward the inner positioning plate to press the inner positioning plate to Tightly combines the positioning frame with the base. [0011] Still another object of the present invention is to provide an electronic device having a core replacement page of 10120143^^^^u A〇101 ^ 4 1 / ^ 20 I 1013180028-0 M434230 101. Good heat dissipation. [0012] In order to achieve the above object, the present invention is an electronic device including the backlight module and a display panel, and the backlight module is disposed on one side of the display panel. [0013] Compared with the prior art, the backlight module of the present invention sets the light source on the inner wall surface of one side of the base, and corresponds to the inner side of one of the positioning plates, and at least one of the other side plates is located. The outer side of at least one of the other positioning plates, because the thermal conductivity of the side plate is higher than the thermal conductivity of the positioning plate, the heat generated by the light source can be quickly transmitted to the side plate, and then the heat is transmitted through the side plate, thereby improving heat dissipation efficiency and increasing The practicality of this creation. DETAILED DESCRIPTION OF THE INVENTION [0014] The detailed description and technical contents of the present invention are described below with reference to the drawings, but the drawings are only for reference and description, and are not intended to limit the present invention. [0015] Please refer to the first to third figures, which are respectively a three-dimensional appearance diagram, an exploded perspective view, and a partial three-dimensional combination diagram of the backlight module of the present invention; the backlight module 1 of the present invention includes a base 10 An optical film set 20, a positioning frame 30, and a light source 40. The susceptor 10 includes a bottom plate 11 and a plurality of side plates 12 adjacent to the bottom plate 11. The bottom plate 11 and the side plates 12 are defined as an accommodating space 100.
