BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a light source assembly and a display device and, more particularly, to a light source assembly capable of reducing an optical distance effectively and a display device equipped with the light source assembly.

2. Description of the Prior Art

Since a liquid crystal display (LCD) has advantages of thin thickness, light weight, low power consumption, no radiation pollution, and being compatible with semiconductor process, it has been applied in various electronic devices including notebook, mobile phone, digital still camera, personal digital assistant, and so on. The LCD utilizes a backlight module to provide light for a display panel, so as to display images. At present, the backlight module comprises a direct type backlight module and an edge type backlight module. Since a light source of the direct type backlight module is distributed uniformly behind a display panel, the direct type backlight module may obtain more uniform image. In order to mix light, a specific distance has to be kept between the light source of the direct type backlight module and optical films, wherein the distance is an optical distance. In general, the optical distance is usually between 15 mm and 35 mm, such that the whole thickness of the display device equipped with the direct type backlight module cannot be reduced. Thus, it is not beneficial to thin the display device.

SUMMARY OF THE INVENTION

The invention provides a light source assembly capable of reducing an optical distance effectively and a display device equipped with the light source assembly, so as to solve the aforesaid problems.

According to an embodiment of the invention, a light source assembly comprises a plurality of light source modules. Each of the light source modules comprises a base, a light emitting unit and a light guide member. The light guide member has an accommodating space. The light emitting unit and the light guide member are disposed on the base and the light emitting unit is located in the accommodating space. At least one of the base and the light guide member has a first connecting structure and a second connecting structure. The first connecting structure of one of the light source modules is connected to the second connecting structure of another one of the light source modules, such that the light source modules are connected to each other to form the light source assembly.

According to an embodiment of the invention, a display device comprises a plate, a light source and a display panel. The light source assembly is disposed on the plate. The light source assembly comprises a plurality of light source modules. Each of the light source modules comprises a base, a light emitting unit and a light guide member. The light guide member has an accommodating space. The light emitting unit and the light guide member are disposed on the base and the light emitting unit is located in the accommodating space. At least one of the base and the light guide member has a first connecting structure and a second connecting structure. The first connecting structure of one of the light source modules is connected to the second connecting structure of another one of the light source modules, such that the light source modules are connected to each other to form the light source assembly. The display panel is disposed on the light source assembly.

As mentioned in the above, the light source module essentially consists of the base, the light emitting unit and the light guide member and the light source module has the connecting structures configured to connect other light source modules. Accordingly, the invention can connect a plurality of light source modules with each other to form a planar light source assembly. Since the light guide member of the light source module can diffuse point light source into surface light source within a short distance, the invention can reduce the optical distance effectively. When the light source assembly of the invention is served as a direct type backlight module, it is beneficial to thin the display device.

These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
