Description

顯示裝置及其背光模組Display device and backlight module thereof
本發明是有關於一種背光模組,且特別是有關於一種省略膠框之背光模組及具有此種背光模組之顯示裝置。The present invention relates to a backlight module, and more particularly to a backlight module that omits a plastic frame and a display device having the same.
隨著消費性電子及通訊產品的發展,液晶顯示器(Liquid Crystal Display,LCD)已廣泛地應用於液晶電視、筆記型電腦、桌上型電腦,以及智慧型手機(Smart Phone)等產品。一般來說,液晶顯示器包括液晶顯示面板(Display Panel)及背光模組(Backlight Module)。With the development of consumer electronics and communication products, liquid crystal displays (LCDs) have been widely used in LCD TVs, notebook computers, desktop computers, and smart phones. Generally, a liquid crystal display includes a liquid crystal display panel (Display Panel) and a backlight module (Backlight Module).
背光模組之功能即在於供應充足的亮度與分佈均勻的光源,使本身不發光的液晶能顯示影像。背光模組為液晶顯示器的光源,由光源、導光板(Light Guide Plate,LGP)、膠框及鐵框等元件所組成。背光模組的膠框可以防止光源從導光板邊緣漏光,並提供液晶顯示面板及光學膜片組的定位。然而,受限於膠框的設置,使得背光模組之鐵框在設計時常需要配合膠框的結構作卡合結構。鐵框的卡合結構之設計常會對鐵框結構造成破壞,因而降低鐵框的整體強度。另外,膠框在製程上的厚度至少要4~5毫米(mm)。因此,膠框的設置亦增加整體背光模組的輪廓尺寸。The function of the backlight module is to supply a sufficient light source with uniform brightness and uniform distribution, so that the liquid crystal that does not emit light can display images. The backlight module is a light source of the liquid crystal display, and is composed of a light source, a light guide plate (LGP), a plastic frame and an iron frame. The plastic frame of the backlight module can prevent the light source from leaking light from the edge of the light guide plate and provide positioning of the liquid crystal display panel and the optical film group. However, due to the arrangement of the plastic frame, the iron frame of the backlight module often needs to be matched with the structure of the plastic frame as a snap structure. The design of the snap-fit structure of the iron frame often causes damage to the iron frame structure, thereby reducing the overall strength of the iron frame. In addition, the thickness of the plastic frame on the process must be at least 4 to 5 millimeters (mm). Therefore, the setting of the plastic frame also increases the outline size of the overall backlight module.
本發明係有關於一種背光模組及具有此種背光模組之顯示裝置,不需膠框的設置即可達到反射光線及固定面板之效果,因而可以縮減背光模組之外緣輪廓。The invention relates to a backlight module and a display device having the same, which can achieve the effect of reflecting light and fixing the panel without the need of a plastic frame, thereby reducing the outer edge contour of the backlight module.

Panel 20 (shown in Figure 1A) does not directly contact optical film set 108. It should be noted that the pasting position of the first attaching component 112 may not correspond to the area of the visible area AA of the display panel 20 (shown in FIG. 1A).
請參考第6圖,繪示如第1B圖之背光模組10之區域A5的局部放大圖。如第6圖所示,承載框架102具有一第一側面1021,第一側面1021具有彎折部C1及彎折部C2,彎折部C1與彎折部C2相鄰。彎折部C1及彎折部C2係延伸於第一側面1021之邊緣,且彎折部C1及彎折部C2朝向光學膜片組108之側延伸。相鄰之彎折部C1及彎折部C2之間係形成一開口S,可見一光源116設置於開口S中,但光源116位置不僅限於開口S區域。第一舌片T1位於承載框架102之側面外側,與彎折部C1及彎折部C2之彎折方向相反。第一舌片T1之孔K所在的平面其高度低於彎折部C1及彎折部C2所在的平面之高度。Please refer to FIG. 6 for a partial enlarged view of the area A5 of the backlight module 10 as shown in FIG. 1B. As shown in FIG. 6, the carrier frame 102 has a first side surface 1021. The first side surface 1021 has a bent portion C1 and a bent portion C2, and the bent portion C1 is adjacent to the bent portion C2. The bent portion C1 and the bent portion C2 extend along the edge of the first side surface 1021, and the bent portion C1 and the bent portion C2 extend toward the side of the optical film group 108. An opening S is formed between the adjacent bent portion C1 and the bent portion C2. It can be seen that a light source 116 is disposed in the opening S, but the position of the light source 116 is not limited to the opening S region. The first tongue T1 is located outside the side surface of the carrier frame 102, and is opposite to the bending direction of the bent portion C1 and the bent portion C2. The plane of the hole K of the first tongue T1 is lower than the height of the plane where the bent portion C1 and the bent portion C2 are located.
於此實施例中,一第二貼附元件114黏貼於第一側面1121之彎折部C1及彎折部C2上方,且第二貼附元件114覆蓋於開口S上。黏貼完成之第二貼附元件114除了可以保護開口S內的光源116,並固定光學膜片組108於承載框架102內,還可以作為顯示面板20(繪示於第1A圖)與光學膜片組108之間的緩衝,使得顯示面板20(繪示於第1A圖)不會直接地接觸到光學膜片組108。值得注意的是,第二貼附元件114的黏貼位置不可以對應到顯示面板20之可視區AA(繪示於第1A圖)的區域範圍。In this embodiment, a second attaching member 114 is adhered to the bent portion C1 and the bent portion C2 of the first side surface 1121, and the second attaching member 114 covers the opening S. The second attached component 114 can be used to protect the light source 116 in the opening S and fix the optical film set 108 in the carrier frame 102, and can also serve as the display panel 20 (shown in FIG. 1A) and the optical film. The buffering between groups 108 is such that display panel 20 (shown in Figure 1A) does not directly contact optical film set 108. It should be noted that the pasting position of the second attaching component 114 may not correspond to the area of the visible area AA of the display panel 20 (shown in FIG. 1A).
綜上所述,本發明上述實施例之背光模組,藉由反射結構的設置,可以避免光源於導光板外緣漏光。並且,反射結構之第二反射片可以固定顯示面板並作為顯示面板與承載框架之間的緩衝。反射結構之第二反射片更可以朝向光學膜片組的方向彎折,且貼附於光學膜片組之表面上,以固定光學膜片組於承載框架內,且作為顯示面板與光學膜片組之間的緩衝,使得顯示面板不會直接地接觸到光學膜片組。如此一來,可以省去膠框的設置。In summary, the backlight module of the above embodiment of the present invention can prevent the light source from leaking light on the outer edge of the light guide plate by the arrangement of the reflective structure. Moreover, the second reflective sheet of the reflective structure can fix the display panel and serve as a buffer between the display panel and the carrier frame. The second reflective sheet of the reflective structure is further bent toward the optical film group and attached to the surface of the optical film set to fix the optical film set in the carrying frame, and serves as a display panel and an optical film. The buffering between the groups is such that the display panel does not directly contact the optical film set. In this way, the setting of the plastic frame can be omitted.
本發明上述實施例之背光模組,相較於傳統具有膠框之背光模組,其單一側邊即可以省去大約4mm~5mm的距離。因此,背光模組外緣輪廓之整體的長度及寬度,均可以減少大約8mm~10mm的距離,可以降低背光模組之外緣輪廓大小,有利於顯示裝置微型化。由於省略了膠框的設置,可以避免傳統之承載框架需配合膠框的設計時的結構破壞,並提升背光模組的整體結構強度。此外,本發明上述實施例之背光模組,還可以降低模具設計的複雜度,降低模具的開發成本及開發時程。The backlight module of the above embodiment of the present invention can save a distance of about 4 mm to 5 mm on a single side compared with the conventional backlight module with a plastic frame. Therefore, the overall length and width of the outer edge contour of the backlight module can be reduced by about 8 mm to 10 mm, and the outer edge contour of the backlight module can be reduced, which is advantageous for miniaturization of the display device. Since the setting of the plastic frame is omitted, the structural damage of the traditional bearing frame to match the design of the plastic frame can be avoided, and the overall structural strength of the backlight module is improved. In addition, the backlight module of the above embodiment of the present invention can also reduce the complexity of the mold design, and reduce the development cost and development time of the mold.
綜上所述,雖然本發明已以較佳實施例揭露如上,然其並非用以限定本發明。本發明所屬技術領域中具有通常知識者,在不脫離本發明之精神和範圍內,當可作各種之更動與潤飾。因此,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。In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention.
