Description
本發明是有關於一種背光模組，且特別是有關於具有彈性固定元件與頂抵元件的背光模組。The present invention relates to a backlight module, and more particularly to a backlight module having an elastic fixing member and a topping member.
請參照圖1，其為習知側光式背光模組俯視示意圖。如圖1所示，背光模組1包括背板10、導光板11以及光源12。導光板11設置於背板10，而光源12設置於背板10並對應於導光板11之入光面110。導光板11上與入光面110相鄰的側面111、112分別具有多個凹槽113，而背板10具有多個定位元件101。當導光板11組設於背板10上時，背板10的多個定位元件101會容置於導光板11側面111、112上的多個凹槽113內，使得導光板11能夠固定於背板10上。Please refer to FIG. 1 , which is a top view of a conventional edge-lit backlight module. As shown in FIG. 1 , the backlight module 1 includes a back plate 10 , a light guide plate 11 , and a light source 12 . The light guide plate 11 is disposed on the back plate 10, and the light source 12 is disposed on the back plate 10 and corresponds to the light incident surface 110 of the light guide plate 11. The side faces 111, 112 of the light guide plate 11 adjacent to the light incident face 110 respectively have a plurality of grooves 113, and the back plate 10 has a plurality of positioning members 101. When the light guide plate 11 is assembled on the back plate 10, the plurality of positioning elements 101 of the back plate 10 are received in the plurality of grooves 113 on the sides 111, 112 of the light guide plate 11, so that the light guide plate 11 can be fixed on the back. On the board 10.
然而，凹槽113與定位元件101因公差的存在，當定位元件101容置於凹槽113內時，定位元件101與凹槽113之間會有間隙100的產生，而此間隙100會造成導光板11產生移動的情況。當導光板11移動時，導光板11與光源12之間的間隙100a也會相對產生變化，舉例來說，如圖1所示，當導光板11朝A方向移動時，導光板11與光源12之間的間隙100a會變小，而當導光板11朝B方向移動時，導光板11與光源12之間的間隙100a會變大。上述間隙100a變化的情況會對光學輝度(亮度)或者是色彩均勻度造成影響。此外，在對上述背光模組1結構進行衝擊與震動測試時，會有定位元件101歪斜或者是造成導光板11破裂的情況發生。However, due to the presence of tolerances of the recess 113 and the positioning member 101, when the positioning member 101 is received in the recess 113, there is a gap 100 between the positioning member 101 and the recess 113, and the gap 100 causes a guide. The light panel 11 produces a movement. When the light guide plate 11 moves, the gap 100a between the light guide plate 11 and the light source 12 also changes relatively. For example, as shown in FIG. 1, when the light guide plate 11 moves in the A direction, the light guide plate 11 and the light source 12 are The gap 100a between them becomes small, and when the light guide plate 11 moves in the B direction, the gap 100a between the light guide plate 11 and the light source 12 becomes large. The change in the gap 100a described above affects optical brightness (brightness) or color uniformity. In addition, when the impact and vibration tests are performed on the structure of the backlight module 1 described above, the positioning member 101 may be skewed or the light guide plate 11 may be broken.

As shown in FIG. 3, when the abutting member 23 abuts against the second side 212 of the light guide plate 21, the light source 25 and the second side 212 of the light guide plate 21 have a proper gap 250. In the present embodiment, when the light guide plate 21 is increased in volume due to an external factor (for example, a temperature rise), the elastic fixing member 22 is deformed by the light-guide plate 21 having an increased volume due to the elastic restoring force, and is deformed. The top abutting member 23 of the second side surface 212 of the light guide plate 21 is made of a metal material, so that deformation is less likely to occur. Therefore, when the light guide plate 21 is deformed, the gap 250 between the second side surface 212 of the light guide plate 21 and the light source 25 can be ensured. Will produce too much change.

綜上所述，本發明所述之背光模組，主要是在導光板具有相對的第一側面與第二側面分別設置彈性固定元件與頂抵元件。彈性固定元件位於導光板的第一側面，且彈性固定元件藉由容置空間來 容置部分的導光板並固定導光板。頂抵元件位於第二側面，用以抵靠導光板。藉由彈性固定元件與頂抵元件的搭配，使得導光板與光源之間的間隙不會產生變化，又由於彈性固定元件具有彈性回復力，當導光板因為溫度變化而產生熱膨冷縮現象時，彈性固定元件仍舊可以對導光板進行固定。In summary, the backlight module of the present invention mainly includes an elastic fixing member and a topping member respectively disposed on the first side surface and the second side surface of the light guide plate. The elastic fixing component is located on the first side of the light guide plate, and the elastic fixing component is provided by the accommodating space A portion of the light guide plate is housed and the light guide plate is fixed. The abutting element is located on the second side for abutting against the light guide plate. By the combination of the elastic fixing element and the abutting element, the gap between the light guide plate and the light source is not changed, and since the elastic fixing element has an elastic restoring force, when the light guide plate is thermally expanded and contracted due to temperature change, The elastic fixing member can still fix the light guide plate.
