The present invention provides a backlight module including a waveguide, a backboard, and a light source, wherein the waveguide is disposed onto the backboard, and the light source is arranged adjacent to a light incident surface of the waveguide, wherein the backlight module includes at least a limiter securely disposed onto the backboard and abuts against to the light source so as to ensure a preset distance between the light source and the incident surface of the waveguide. According to the backlight module and the liquid crystal display, by providing the limiter of the backlight module to abut against the light source, the coupling distance between the light source and the incident surface of the waveguide can be effectively kept constant without being compromised to zero (0) as resulted from expansion under heat or moisture or the accuracy during installation. By this arrangement, the leakage of the backlight module can be readily prevented. In addition, in order to have the limiter readily made as well as reducing the cost, the limiter can be made as a standard part so as to be implemented on the liquid crystal display with different dimension. |

1. A backlight module including a waveguide, a backboard, and a light source, wherein the waveguide is disposed onto the backboard, and the light source is arranged adjacent to a light incident surface of the waveguide, wherein the backlight module includes at least a limiter securely disposed onto the backboard and abuts against to the light source so as to ensure a preset distance between the light source and the incident surface of the waveguide;
wherein the limiter includes a connector and a pusher disposed on the connector, the connector is arranged between the waveguide and the backboard, wherein the connector is rooted onto the backboard so as to support the waveguide, wherein the connector abuts against the light source such that the abutting portion is close to the light source; wherein a heatsink is arranged between the connector and the backboard and includes a recess, a platform and a side; and the connector includes a backbone, and a carrier extending from the backbone, and an inclined transition located between the backbone and the carrier; and wherein the backbone is disposed within the recess, and a locking device passing through the backbone, the recess and the backboard to interlock the backbone, the recess and the backboard together, wherein the carrier is disposed onto the platform so as to carrier the waveguide, and the carrier abutting against the light source and the inclined transition is disposed onto the side of the recess. |
