J ^ Because of this, ‘lifting ship model _ scattered _ — straight is ▲ Gu Please ϋ1’ is a dry sound chart of the side section of the conventional direct type backlight module. Xi: Straight: Qiaoguang module 10 is set on a display surface τ square diagram ^ Two Γ reflection sheet 12, the light source generator and the optics _15 place_, and has-the first room, ^ 1 a 4 M273011 Empty room 17. As shown in the figure, the bottom plate 11 is located at the bottom of the conventional direct type backlight module ι0, and its material has sufficient support strength and heat conduction characteristics. A reflective sheet 12 is affixed above the bottom plate η. The reflective sheet 12 is folded into a continuous mountain-shaped portion 121, and a first cavity μ is formed between the mountain-shaped portion 121 and the substrate 11. A light source generator 13 is provided between the mountain-shaped portion 121 and the side wall 111 or between two adjacent mountain-shaped portions 121. The light source generator 13 is composed of a plurality of cold cathode ray tubes arranged in parallel with each other. The diffusion plate 14 is located on the light source generator 13 and a second cavity 17 is formed therebetween. The diffusion plate 14 is disposed between the light source generator 13 and the display panel 20, and can scatter light from below to provide a more uniformly dispersed light from the display panel 20. A plurality of optical films 15 are usually laid on the diffusion plate 14, such as a lower diffusion sheet, a lower enhancement sheet, an upper enhancement sheet, and an upper diffusion sheet, which are sequentially placed from bottom to top to increase the uniformity of light of the entire display product. With brightness. The “display panel 20” referred to in this article is composed of at least an upper substrate 21 and a lower / substrate ^ 2, and the surfaces of the two substrates have the elements required to form a pixel array (not shown, such as a light sheet, a thin film transistor, and various Electrodes. When the two substrates are aligned up and down, the above elements constitute a complete pixel array to control the passage of light to achieve significant results. Refer to FIG. 2, which is a perspective view of the internal structure of the second cavity 17 of FIG. The reflection sheet 12 is outside the mountain-shaped part 121. The mountain-shaped part 丨 is on a flat bottom plate U, so at least-more than half of the reflection sheet = 11 contacts and conducts the heat generated by the light source generator 13. The direct-type backlight module has the following Disadvantages listed: Knowing the above 1. In order to meet the requirements of high brightness and light weight, the light source generators in the above are often installed; the second empty room shown in the narrow _ Iϋ module 17), Therefore, during the operation, the ==: such as = is smoothly distributed and continuously accumulated. It is said that it is impossible to make the temperature near the lamp tube too high, which cannot be caused. ^ It will cause a reduction in display quality (for example: brightness reduction = positive * shorten the life of surrounding components. The large amount of M273011 touch recessed towels' heat generated by it, and the connection between the chevron and the surface of the fins are increased: they can be smoothly transmitted to the outside. In addition, the material for uniform light energy is high. The heat-conducting version eliminates the need to separately defend the reflective sheet into a mountain-shaped deployment. 5 The direct-type $ light module can be used as a display device. The display device has already included a housing, a display panel, and a backlight module as described above. Product: The Xuanyue light module can prevent the temperature near the light source generator from being too high, maintain the normal operation of the display panel, and extend the service life of its components. "Adding through-holes and fins on its base plate solves the main problem of poor heat dissipation. And, as long as the reflective sheet is covered along the continuous sheet and the surface of the base plate, the mountain-shaped part can be formed naturally, so it is also necessary to process the reflective sheet to form a mountain-shaped part." Difficulty problem. The following is a detailed description of this work with the illustrations, and the preferred embodiment is described as follows. Please refer to FIG. 3 for a perspective view of the direct-type backlight module for this creation. The direct-type moonlight module 30 includes a base plate 31 , A reflection sheet 32, a light source generator 33, and a diffusion plate 34. The difference between this creation and the conventional direct-type backlight module is that the bottom plate 31 includes at least-fins 31, the surface of the fins 311, and a bottom plate-like plate. The surface clips at an inclined angle. The reflection sheet 32 covers the bottom plate 31 and forms a mountain-shaped portion 321 along the surface of the fin 311 and the bottom plate 31. In order to achieve the purpose of heat dissipation, the mountain-shaped portion 321 must keep contact with the surface of the Korean piece 311. The inclination of the sheet 311 can be determined by the above-mentioned inclination angle, and the distance between the top and the bottom of the mountain-shaped portion 321 can be further adjusted. The light source generator 33 is provided on the reflective sheet 32 to provide a light source. The thermal energy contacts the bottom plate 31 through the reflection sheet 32, and the air-shaped contact area is formed between the mountain-shaped portion 321, M273011, and the bottom plate 11 to reduce the product volume and reduce the connection between the reflection sheet and the bottom plate. Improve backlight Cooling capacity of the group, display the product to conform to 1) into two life ί; ίί3: as long as the sheet and the reflective surface coating along a fin forming ridge portion can be naturally 'while it is difficult to solve the problems of the above-described processing. [New content] The main purpose is to increase the fin structure L light mode L on the base plate. ’The surface is in contact with the reflective sheet 1 ^ A direct-down type that increases the heat conduction area to add a through-hole structure to the wire Shape part group-a kind that can save the succession of the succession into a mountain? Γ two kinds of direct-type backlight modules, the direct-type backlight module 5Ϊιί two projection films,-light source generator and-diffuser plate. The floor. The reflecting sheet is covered on the bottom plate and is in contact with the fins and clothes. The high-light source generator is set on the surface of the M273011 connected to the sheet 311 to increase the heat dissipation area of the base plate 31, so that the thermal energy can be smoothly transmitted to the outside. In addition, "in order to allow light to be evenly scattered" in the illustrated junction increase-diffusion plate 34. Still refer to ®3, as a cold cathode hybrid tube or Light Emitting Diode (LED) as the light source generator 33, and do each of the following as appropriate. The wire generation H33 is provided in the recessed portion 322 of the mountain-shaped portion, wherein the mountain-shaped portion 321 is located between the two recessed portions 322. The mountain-shaped portion can be further fitted to the surface of the fin 311 to make full use of its conduction area. The shape of 311 is not particularly limited, such as rectangular and trapezoidal. Fresh flakes are made of aluminum, magnesium, copper, titanium, silver or their alloys; ί 3 = f material. It is worth mentioning that the reflection sheet 32 touches the surface of the bottom plate 31 along the binding piece M1 to form a mountain-shaped part cut, which can eliminate the moustache of the reflection part 321 riding alone. In addition, the sequel 311 is a stamped bottom plate 31 and the heat dissipation effect is enhanced by the convection effect of the second milk. In the figure, i-phase 1A, 'is the bottom plate of a custom-made backlight module with a rectangular shape. The picture does not. &Quot; The film contains at least one forward fin 311a and at least one reverse fin, and the key 1 is bound in the forward direction. The film 31 is folded in a clockwise direction from the base plate 31A, and is reversed from the bottom i: the needle direction starts from the base plate 31. The bottom plate 31A has an edge, and a part of the edge of the second through hole 312b is connected to the source side f. The forward binding piece 31 la and the reverse binding piece 31 ib are parallel light beams iiif. Among them, the bottom plate 3ia can be generally punched by the method Ϊ = to make the first through hole facing and the forward Korean piece 311a at the same time; H3, 12a and the forward fin 3iia are shaped into a single body. The second and second ladder M273011 Please refer to FIG. 5A, which is a perspective view of another type of bottom plate of the direct-type backlight module. The bottom plate 31a includes an upper bottom plate 31b and a lower bottom plate 31c. The upper bottom plate 31b has a member-oriented fin 311a connected to a hole edge of the first through hole 312a. The lower base plate has a reverse fin 31 ib connected to a hole edge of a second through hole (not shown). 5B is a side cross-sectional view of the AA section in FIG. 5A. When the upper base plate 31b and the lower base plate 3lc are stacked one on top of the other, the reverse fins "pass through the first through hole 312a, at this time the first through hole 312a and the second through hole 312b overlap, and the two fins" j'311b /, A convex structure% is formed at the same time, and one of the peaks π!
