Abstract

The invention provides a backlight module and a liquid crystal display device. The backlight module comprises a light guide plate and a light-emitting lamp strip located on the end face of one side ofthe light guide plate; the light-emitting lamp strip comprises a flexible circuit board and multiple light-emitting diodes, and the light-emitting diodes are arranged in the first direction in sequence and are electrically connected with the flexible circuit board; the light-emitting diodes comprise at least one first-type light-emitting diode, and the first-type light-emitting diodes are locatedat the ends of the light-emitting diodes arranged in the first direction in sequence; the light-emitting diodes comprise light-emitting chips and fluorescent glue, the fluorescent glue comprises filling materials and fluorescent powder, the fluorescent glue is in direct contact with the light-emitting chips, the surfaces of the sides, away from the light-emitting chips, of the fluorescent glue are light emergence surfaces of the light-emitting diodes, and the light emergence surface of the first-type light-emitting diode is a convex hook face. Through the arrangement of the convex hook face,the light-emitting angle of the light-emitting diodes is increased, thus the backlight module can illuminate all the display area, and the problem of corner dark shadow of the display area is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a liquid crystal display device. Background technique [0002] Liquid crystal displays have been widely used in various electronic products. Liquid crystal displays mainly include a liquid crystal display panel and a backlight module. The backlight module can be divided into side-type and direct-type according to the incident position of the light source. Compared with the direct type, the side entry type can thin the liquid crystal display, so it has been widely used. [0003] For edge-type backlight modules, in order to meet the trend of narrower bezels of liquid crystal display devices and other requirements, for example, liquid crystal display panels often need to cut corners (cut off the original right angle) to increase the screen ratio. At this time, the backlight module Often faced with the defect of not being able to fully illuminate the display ...
