Fastening Device for LED Light String of Backlight Module and Liquid Crystal Display

摘要

The present invention provides a fastening device for a LED light string of a backlight module, including a LED light string and a frame, the LED light string being configured with a substrate and a plurality of LEDs mounted onto the substrate, wherein at least a retainer is incorporated on the substrate, and the frame being provided with a notch matchable with the retainer such that the LED light string can be securely attached to the frame. The retainer can be made individually, and a SMT process is utilized to attach the retainer of the fastening device on the backside of the LED light string. With this convenient arrangement, a lot of manufacturing processes have been omitted. The LED light string and the frame can be modulated, and the overall configuration of the module is simplified. In addition, with the retainer readily snapped into the notch of the frame, a distance between to the LED light emitting surface to the frame is also reduced, and this helps to realize the design of narrow-boarder of the liquid crystal display.
