Backlight module and liquid crystal display device using same

摘要

The present invention provides a backlight module and a liquid crystal display device using the backlight module. The backlight module includes a backplane (2), a light guide plate (4) arranged in the backplane, a backlight source (6) arranged in the backplane, and a plurality of mounting member (8) in the backplane to position and fix the light guide plate (4). The light guide plate (4) includes a main body (42) and a plurality of mounting sections (44) extending outwards from sides of the main body. Each of the mounting sections (44) includes a first lug (442) and a second lug (444) that are spaced from each other. The mounting members (8) each include a base (82) and first, second, and third positioning pillars (84, 86, 88) extending upwards from the base (82) and arranged sequentially to space from each other. The main body (42) is positioned against the base (82) and the second positioning pillar (86). The first lug (442) is positioned against the base (82) and the first positioning pillar (84). The second lug (444) is positioned against the base (82) and the third positioning pillar (88).

1. A backlight module, comprising: a backplane, a light guide plate arranged in the backplane, a backlight source arranged in the backplane, and a plurality of mounting members arranged in the backplane to position and fix the light guide plate, the light guide plate comprising a main body and a plurality of mounting sections extending outwards from sides of the main body, each of the mounting sections comprising a first lug and a second lug that are spaced from each other, the mounting members each comprising a base and first, second, and third positioning pillars extending upwards from the base and arranged sequentially to space from each other in such a way that the first and third pillars each have an inner side surface and an outer side surface opposite to each other and the inner side surfaces of the first and third pillars respectively face and are spaced from two opposite side surfaces of the second pillar so that the first and second positioning pillars therebetween a first resilient opening that is delimited between the inner side surface of the first pillar and the corresponding side surface of the second pillar and the second and third positioning pillars define therebetween a second resilient opening that is delimited between the inner side surface of the third pillar and the corresponding side surface of the second pillar, the first and second pillars being separated from each other by the first resilient opening, the second and third pillars being separated from each other by the second resilient opening, the main body being positioned against the base and the second positioning pillar, the first lug being positioned against the base and the outer side surface of the first positioning lug that is distant from the second positioning pillar, the second lug being positioned against the base and the outer side surface of the third positioning lug that is distant from the second positioning pillar.
