Abstract
The present invention relates to an edge-lit backlight model, which comprises a back board, a heat sink arranged on the back board, and a light bar fixed on the heat sink, a light guiding plate is arranged above the back board, a plurality of back board clips are arranged on the back board and the heat sink is held under the back board clips; a elastic element is arranged between the back board and the heat sink and the elastic element applies horizontal elastic force to the heat sink towards the back board, so that the heat sink is immovable along its width direction. The edge-lit backlight model can prevent the light guiding plate from being bent and guarantee the efficiency of light coupling.
