摘要： A backlight module includes a frame, a light bar, and a locating bar. The locating bar is connected between two sides of the frame. The light bar includes a circuit board and a plurality of lighting units, where the circuit board is secured on a support of the frame, and where the plural lighting units are engaged with plural locating grooves of the locating bar, such that the lighting units are confined by the locating grooves in a lateral direction. Therefore, during the steps in assembling the light bar, not only personnel are facilitated in the assembly work, but also the light bars can be sieved out during the assembly process, preventing the defect of material waste if illumination test is performed only after the whole backlight module has been finished.
摘要翻译：背光模块包括框架，灯条和定位杆。定位杆连接在框架的两侧之间。灯条包括电路板和多个照明单元，其中电路板固定在框架的支撑件上，并且多个照明单元与定位杆的多个定位槽接合，使得照明单元由横向方向的定位槽限制。因此，在组装灯条的步骤中，不仅在组装工作中方便了人员，而且在组装过程中也可以将灯条过筛，防止仅在整个照射后进行照明测试时材料浪费的缺陷背光模块已经完成。

摘要： A backlight module having a light diffusing device is disclosed, comprising a frame, a reflecting plate, a top plate, at least one light source, and at least one diffusing plate, in which the reflecting plate having an upper surface is mounted at a bottom side of the frame and the top plate is mounted on a top side of the frame to space a predetermined distance from the reflecting plate. The light source is mounted on the upper surface of the reflecting plate. The light diffusing plate is mounted on the lower surface of the top plate, and the light diffusing plate is corresponding to the light source. The light diffusing plate having an un-uniform thickness inversely proportional to the distance between the light source and the top plate.

The light source module is mounted on the upper surface of the reflecting plate, including a light source and a light diffusing device mounted between the light source and the top plate. The light diffusing device has an un-uniform thickness which is inversely proportional to the distance between the light source and the top plate. Thus, the problem of non-uniform luminance distribution caused by a change in the distance between the light source and the top plate is eliminated.
