Description
本發明是有關於一種背光模組以及顯示模組，且特別是有關於一種可同時兼顧導光板之應力緩衝以及光學膜片定位效果的背光模組以及顯示模組。The present invention relates to a backlight module and a display module, and more particularly to a backlight module and a display module that can simultaneously consider the stress buffer of the light guide plate and the optical film positioning effect.
隨著光電技術與半導體製造技術的日益成熟，平面顯示裝置蓬勃發展。其中，液晶顯示器基於其低電壓操作、無輻射線散射、重量輕以及體積小等優點，逐漸取代傳統的陰極射線管顯示器，而成為近年來顯示器產品之主流。With the increasing maturity of optoelectronic technology and semiconductor manufacturing technology, flat display devices are booming. Among them, based on its low voltage operation, no radiation scattering, light weight and small size, the liquid crystal display has gradually replaced the traditional cathode ray tube display, and has become the mainstream of display products in recent years.
圖1繪示習知一種液晶顯示模組。圖2A為圖1之液晶顯示模組的剖面圖。圖2B為圖1之液晶顯示模組的另一剖面圖。為了清楚表達結構特點，圖1省略了前框、液晶顯示面板、承載框等構件。FIG. 1 illustrates a conventional liquid crystal display module. 2A is a cross-sectional view of the liquid crystal display module of FIG. 1. 2B is another cross-sectional view of the liquid crystal display module of FIG. 1. In order to clearly express structural features, FIG. 1 omits components such as a front frame, a liquid crystal display panel, and a carrier frame.
如圖1與2A所示，液晶顯示模組100包括背光模組110、液晶顯示面板120以及前框130等構件，其中液晶顯示面板120設置於背光模組110上，而前框130組裝於液晶顯示面板120上，以固定背光模組110與液晶顯示面板120的相對位置。As shown in FIG. 1 and FIG. 2A, the liquid crystal display module 100 includes a backlight module 110, a liquid crystal display panel 120, and a front frame 130. The liquid crystal display panel 120 is disposed on the backlight module 110, and the front frame 130 is assembled on the liquid crystal. The display panel 120 is configured to fix the relative positions of the backlight module 110 and the liquid crystal display panel 120.
背光模組110包括底板112、導光板114、光源裝置116、承載框118以及光學膜片119等，其中為了固定導光板114以及光學膜片119的位置，底板112上需形成定位柱112a，並且在導光板114以及光學膜片119上開設對應的開口114a與119a，使定位柱112a經由開口114a與119a貫穿導光板114以及光學膜片119。The backlight module 110 includes a bottom plate 112, a light guide plate 114, a light source device 116, a bearing frame 118, an optical film 119, and the like. In order to fix the positions of the light guide plate 114 and the optical film 119, a positioning post 112a is formed on the bottom plate 112, and Corresponding openings 114a and 119a are formed in the light guide plate 114 and the optical film 119, so that the positioning post 112a penetrates the light guide plate 114 and the optical film 119 via the openings 114a and 119a.
然而，習知此種背光模組110需要在底板112上額外製作定位柱112a，且導光板114以及光學膜片119上也需要分別形成開口114a與119a，因此製作成本高。另外，定位柱112a與開口114a與119a之間的對位不易，組裝過程繁複，而導光板114可能受熱膨脹變形而無法與定位柱112a的位置準確配合。光學膜片119也容易在組裝過程中脫離定位柱112a。However, it is known that the backlight module 110 needs to additionally form the positioning post 112a on the bottom plate 112, and the openings 114a and 119a are separately formed on the light guide plate 114 and the optical film 119, so that the manufacturing cost is high. In addition, the alignment between the positioning post 112a and the openings 114a and 119a is not easy, the assembly process is complicated, and the light guide plate 114 may be thermally expanded and deformed to be incapable of accurately matching the position of the positioning post 112a. The optical film 119 is also easily detached from the positioning post 112a during assembly.
此外，定位柱112a會佔用背光模組110的內部空間，且不利於背光模組110的薄型化與窄邊化，相對限制背光模組110的發展。若定位柱112a與底板112同為金屬件製成，則可能反射光線而導致漏光。再者，定位柱112a本身結構較為脆弱，可能在後續的可靠度測試或運送、使用的過程中損壞。In addition, the positioning pillar 112a occupies the internal space of the backlight module 110, and is not conducive to the thinning and narrowing of the backlight module 110, and relatively restricts the development of the backlight module 110. If the positioning post 112a and the bottom plate 112 are made of a metal member, light may be reflected to cause light leakage. Moreover, the positioning post 112a itself is relatively fragile and may be damaged during subsequent reliability testing or transportation and use.
另一方面，如圖2B所示，為了固定導光板114的位置，承載框118與導光板114之間必須設置橡膠塊140，以藉由橡膠塊140來壓著並固定導光板114。如此，亦增加了製作成本與組裝複雜度。On the other hand, as shown in FIG. 2B, in order to fix the position of the light guide plate 114, a rubber block 140 must be disposed between the bearing frame 118 and the light guide plate 114 to press and fix the light guide plate 114 by the rubber block 140. In this way, the production cost and assembly complexity are also increased.

Figure 7 is a cross-sectional view of the display module of the present embodiment. In order to clearly express the structural features, FIG. 6 omits components such as a front frame, a display panel, and a carrier frame. The display module 600 of the present embodiment is similar to the display module 200 shown in FIG. 4, the main difference being that the top wall 612 of the cushioning material 610 further includes a plurality of bumps 620. The protrusion 620 protrudes from the other side of the carrying frame 630 through the opening 632 of the carrying frame 630 to bear against the bottom of the display panel 640 .
此外，本發明的凸塊的位置、數量、形狀還可視需求而調整。圖8繪示圖7之顯示模組的一個變形例，且圖8的顯示模組是結合圖5A與5B的凹陷設計所做的改動。如圖8所示，頂壁842的底部具有凹陷842a，而頂壁842的頂部可形成凸塊810，特別是凸塊810可位於凹陷842a上方或者凸塊810可為延伸至導光板820相對兩側的完整的條狀肋，以承靠顯示面板830。In addition, the position, number, and shape of the bumps of the present invention can also be adjusted as needed. FIG. 8 illustrates a modification of the display module of FIG. 7, and the display module of FIG. 8 is a modification made in conjunction with the recessed design of FIGS. 5A and 5B. As shown in FIG. 8, the bottom of the top wall 842 has a recess 842a, and the top of the top wall 842 can form a bump 810. In particular, the bump 810 can be located above the recess 842a or the bump 810 can extend to the light guide plate 820. A complete strip of ribs on the side to bear against the display panel 830.
另外，圖9繪示依照本發明之又一實施例的一種顯示模組。圖10為圖9之顯示模組的剖面圖。為了清楚表達結構特點，圖9省略了前框、顯示面板以及承載框等構件。In addition, FIG. 9 illustrates a display module according to still another embodiment of the present invention. Figure 10 is a cross-sectional view of the display module of Figure 9. In order to clearly express the structural features, FIG. 9 omits components such as a front frame, a display panel, and a carrier frame.
如圖9與10所示，本實施例的顯示模組900並未形成如圖4與5的定位結構，而是改為將光學膜片910的邊緣912***緩衝材920的頂壁922與導光板930之間，以藉由緩衝材920的頂壁922與導光板930來夾持光學膜片910。本實施例的設計在組裝定位上更為簡易，且光學膜片910的邊緣不需要形成定位結構，在製作上較為容易，有助於降低製作成本。另外，由於光學膜片910的邊緣與導光板930的邊緣幾乎切齊，因而可在光學膜片910與導光板930之間提供較好的定位效果。當然，本實施例的顯示模組仍可結合前述實施例的凸塊設計，在頂壁922的頂部形成凸塊(或條狀肋)960，使其穿過承載框940來承載顯示面板950。As shown in FIGS. 9 and 10, the display module 900 of the present embodiment does not form the positioning structure of FIGS. 4 and 5, but instead inserts the edge 912 of the optical film 910 into the top wall 922 of the cushioning material 920 and the guide. The optical film 910 is sandwiched between the light plates 930 by the top wall 922 of the cushioning material 920 and the light guide plate 930. The design of the embodiment is simpler in assembly and positioning, and the edge of the optical film 910 does not need to form a positioning structure, which is easy to manufacture and helps to reduce the manufacturing cost. In addition, since the edge of the optical film 910 is almost aligned with the edge of the light guide plate 930, a better positioning effect can be provided between the optical film 910 and the light guide plate 930. Of course, the display module of the present embodiment can still be combined with the bump design of the foregoing embodiment to form a bump (or strip rib) 960 on the top of the top wall 922 to pass through the carrier frame 940 to carry the display panel 950.
綜上所述，本發明對背光模組的緩衝材進行設計，使其包覆導光板的側邊，並且延伸至導光板的頂面與底面上，以對導光板提供定位、支撐以及緩衝的效果。由於省略了習知的定位柱，因此製作成本較低，且可釋放背光模組內部的空間，以利薄型化與窄邊化的發展。此外，緩衝材可對導光板以及光學膜片提供定位效果，因此可降低組裝複雜度，提升組裝良率與效率。In summary, the buffer material of the backlight module is designed to cover the side of the light guide plate and extend to the top surface and the bottom surface of the light guide plate to provide positioning, support and buffer for the light guide plate. effect. Since the conventional positioning column is omitted, the manufacturing cost is low, and the space inside the backlight module can be released to facilitate the development of thinning and narrowing. In addition, the cushioning material can provide positioning effects on the light guide plate and the optical film, thereby reducing assembly complexity and improving assembly yield and efficiency.
雖然本發明已以實施例揭露如上，然其並非用以限定本發明，任何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，當可作些許之更動與潤飾，故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。Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention.
