In the prior art, there is a gap between the light source and the light guide plate, and the light emitted by the light source leaks through the gap between the light source and the light guide plate, so that the light emitted by the light source cannot completely enter the light guide plate, causing the light incident rate of the light guide plate to be biased. Low

Abstract

The invention provides a backlight module and a liquid crystal display device. The backlight module comprises a back board, a light guiding plate, a light source and a glue frame. A containing space is formed by the back board and the glue frame and used for containing the light guiding plate and the light source. The light guiding plate is close to the back board. The light guiding plate comprises a first side face and a second side face which are opposite to each other. The first side face is close to the light source to serve as the light inlet face of the light guiding plate. The back board comprises a back board body and at least one pressing mechanism which extends into the containing space from the back board body and abuts against the second side face of the light guiding plate so that the first side face of the light guiding plate can be close to the light outlet face of the light source, and the pressing mechanism and the back board body are integrally formed. According to the backlight module and the liquid crystal display device, the light guiding plate has a high light inlet rate.

Description

technical field [0001] The invention relates to the display field, in particular to a backlight module and a liquid crystal display device. Background technique [0002] The backlight module is an important part of a liquid crystal display (Liquid Crystal Display, LCD). Since the liquid crystal itself does not emit light, a backlight module is required to provide light. The backlight module guides the light emitted by the light source into a flat light source by the light guide plate to supply the liquid crystal display panel. In the prior art, there is a gap between the light source and the light guide plate, and the light emitted by the light source leaks through the gap between the light source and the light guide plate, so that the light emitted by the light source cannot completely enter the light guide plate, causing the light incident rate of the light guide plate to be biased. Low. Contents of the invention [0003] The invention provides a backlight module, and...
