摘要:
A structure for eliminating bright lines of a tiled backlight module is provided. The structure includes a light guide plate, and a plurality of light sources. The light guide plate includes a plurality of rows of optical elements. The rows of optical elements extend in parallel. The light sources are provided at least one side of the light guide plate for projecting a light into the light guide plate and generating a regular but non-uniform light outputting performance of the light guide plate. Therefore, a brightness of areas where the optical elements are located is higher than the rest areas, so that the light guide plate achieves a regular but non-uniform light emitting performance. Accordingly, the bright lines occurred at joints between two light guide plates are enshrouded by the high brightness areas, and become hard to identify or even undistinguishable, thus “eliminated”.
