本發明是有關於一種背光模組及應用此背光模組之液晶顯示裝置，且特別是有關於一種可減少或消除漏光之背光模組。The present invention relates to a backlight module and a liquid crystal display device using the same, and more particularly to a backlight module capable of reducing or eliminating light leakage.
一般來說，液晶顯示裝置包含一用來播放影像的液晶顯示板，以及一背光模組，係設於液晶顯示板後方並提供液晶顯示板光源。通常液晶顯示裝置的重量、大小與能源消耗均取決於背光模組。而應用於手機與筆記型電腦時，液晶顯示裝置則特別需求有輕、薄以及低能量損耗的優點。因此，就必須發展出可滿足上述液晶顯示裝置的背光模組。Generally, a liquid crystal display device includes a liquid crystal display panel for playing an image, and a backlight module disposed behind the liquid crystal display panel and providing a liquid crystal display panel light source. Generally, the weight, size and energy consumption of the liquid crystal display device depend on the backlight module. When applied to mobile phones and notebook computers, liquid crystal display devices are particularly required to have the advantages of lightness, thinness, and low energy loss. Therefore, it is necessary to develop a backlight module that can satisfy the above liquid crystal display device.
第1圖係繪示依照一習知背光模組100之側視圖。背光模組100包含一光源110、一導光板120以及一框架130。導光板120用以導引自光源110產生的光線，而框架130則用以容置及固定光源110以及導光板120。FIG. 1 is a side view showing a conventional backlight module 100. The backlight module 100 includes a light source 110, a light guide plate 120, and a frame 130. The light guide plate 120 is used to guide the light generated from the light source 110, and the frame 130 is used to receive and fix the light source 110 and the light guide plate 120.
導光板120包含一光入射面121、一光出射面122以及一反射面123。自光源110產生的光線射至光入射面121。光入射面121接收從光源110發射的光且鄰近於光源110的位置。光出射面122發射穿過光入射面121的光且面向反射面123。反射面123用以反射穿過光入射面121的光且從光入射面121的第二末端部分121b延伸。光入射面的高度“h”大於位於反射面123及光出射面122間的第一 線性距離“d”。光出射面122包含第一光出射面122a與第二光出射面122b，第一光出射面122a從光入射面121的第一末端部分121a延伸且傾斜於反射面123，而第二光出射面122b係由第一光出射面122a延伸且平行於反射面123。The light guide plate 120 includes a light incident surface 121, a light exit surface 122, and a reflective surface 123. Light generated from the light source 110 is incident on the light incident surface 121. The light incident surface 121 receives the light emitted from the light source 110 and is adjacent to the position of the light source 110. The light exit surface 122 emits light that passes through the light incident surface 121 and faces the reflective surface 123. The reflecting surface 123 is for reflecting light passing through the light incident surface 121 and extending from the second end portion 121b of the light incident surface 121. The height "h" of the light incident surface is greater than the first between the reflective surface 123 and the light exit surface 122 Linear distance "d". The light exit surface 122 includes a first light exit surface 122a and a second light exit surface 122b.

然而，上述背光模組100結構雖然可滿足輕、薄的需求。但是，框架130的一部分雖然會遮住光源110和導光板120入光側的上方。但習知的背光模組所使用的框架130，則會因為第一光出射面122a與第二光出射面122b間的落差導致漏光的問題產生，使得液晶顯示裝置會有局部亮點。However, the backlight module 100 described above can meet the requirements of lightness and thinness. However, a part of the frame 130 covers the light source 110 and the light incident side of the light guide plate 120. However, the frame 130 used in the conventional backlight module causes a problem of light leakage due to the difference between the first light exit surface 122a and the second light exit surface 122b, so that the liquid crystal display device has a local bright spot.
因此，如何降低或消除上述背光模組的漏光問題，已成為目前研究發展的主要課題之一。Therefore, how to reduce or eliminate the light leakage problem of the above backlight module has become one of the main research topics at present.
