The present invention provides a side-edge backlight module including a light guide plate having first and second mounting sides opposite to each other. The first mounting side forms a first positioning hole, a first positioning slot, and a second positioning slot. The second mounting side forms correspondingly a second positioning hole, a third positioning slot, and a fourth positioning slot. A backplane includes six rivet pins respectively received in the first and second positioning holes and the first, second, third, and fourth positioning slots. The first and second positioning slots and the third and fourth positioning slots are of a right-angled trapezoidal shape having a straight side that is open and an inclined side that is inclined downward in a direction toward the first or second positioning hole. The rivet pins received in the first, second, third, and fourth positioning slots respectively abut against the inclined sides of the trapezoids. |

1. A side-edge backlight module, comprising: a backplane, two backlight sources that are arranged in the backplane to be opposite to each other, and a light guide plate that is arranged inside the backplane and between the two backlight sources, the light guide plate comprising two opposite light incidence sides and a first mounting side and a second mounting side that are located between the two light incidence sides and are opposite to each other, the two backlight sources being set to respectively correspond to the two light incidence sides, the first mounting side forming a first positioning hole and also forming a first positioning slot and a third positioning slot on opposite sides of the first positioning hole, the second mounting side forming a second positioning hole corresponding to the first positioning hole, the second mounting side forming a second positioning slot and a fourth positioning slot on opposite sides of the second positioning hole to correspond to the first positioning slot and the third positioning slot, the backplane comprising six rivet pins mounted thereon to be respectively received in the first and second positioning holes and the first, second, third, and fourth positioning slots in order to effect positioning of the light guide plate, the first and third positioning slots being each of a right-angle trapezoidal shape with a straight side thereof open and an inclined side being inclined downward in a direction toward the first positioning hole, the second and fourth positioning slots being each of a right-angle trapezoidal shape with a straight side thereof open and an inclined side being inclined downward in a direction toward the second positioning hole, the rivet pins received in the first, second, third, and fourth positioning slots respectively abutting against the inclined sides of the trapezoids. |
