Embodiment Construction

[0018] Please refer to FIG. 2 , which is a schematic cross-sectional view of the first embodiment of the backlight module of the present invention. The backlight module 2 includes a light guide plate 21, a light source 22, a light source cover 23 and a back frame 24, the light source 22 is located on one side of the light guide plate 21, the light source cover 23 is arranged around the light source 22, and the back frame 24 fixes the light guide plate 21 and light source 22 .

[0019] The light guide plate 21 includes a light incident surface 211 for receiving light, a light exit surface 212 intersecting with the light incident surface 211 for guiding the light to exit, a bottom surface 214 opposite to the light exit surface 212, three intersecting the light exit surface and the bottom surface The side surfaces 213 of the light guide plate 21 are inclined.

[0020] The light emitted by the light source 22 enters the light guide plate 21 through the light incident surface 211,...

Abstract

This invention relates to one aphototropism module set, which comprises one light source, one light board and one back frame, wherein, the frame contains light source and light guide board with one incident surface and one emergent surface to guide the light crossing with incident surface and one bottom surface relative to the emergent surface and the side surface crossing with the emergent surface; the light source is in one side of the incident surface; the guide board side and its relative back frame side has anti-leakage structure to prevent leakage phenomena from the gap between the side surface and back frame.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to an edge-light backlight module. 【Background technique】 [0002] Since the liquid crystal in the liquid crystal display panel does not emit light itself, in order to achieve the display effect, it is necessary to provide the liquid crystal display panel with a light source device, such as a backlight module, to realize the display function. [0003] The prior art backlight module includes a light source and a light guide plate. The light source is arranged relative to the light incident surface of the light guide plate. The light guide plate guides the transmission direction of the light emitted by the light source and converts the line light source or point light source into a surface light source to emit. A plurality of dots are distributed on the bottom of the light guide plate to destroy the total reflection condition of light transmission inside the light guide plate, and make it diffu...
