Problems solved by technology

Since the side-emitting light emitting diode 10 and the top-emitting light-emitting diode 20 are respectively arranged at the end positions on the rigid circuit board PCB and the flexible circuit board FPC, the light emitted by the side-emitting light-emitting diode 10 and the top-emitting light-emitting diode 20 Light enters from the corner of the light guide plate, which makes it difficult to adjust the optical performance of the middle area of ​​the backlight module, making it easy to have dark areas with insufficient brightness in the middle area of ​​the screen displayed by the LCD

Abstract

A backlight module and a light source module thereof are disclosed. The light source module includes a substrate, at least one first light source, and at least one second light source. The substrate includes a first substrate portion and a second substrate portion. The first substrate portion extends along a length direction, and the second substrate portion bends an acute angle corresponding to an extending surface of the first substrate portion. The at least one first light source and the at least one second light source are disposed on the first substrate portion and the second substrate portion respectively. The acute angle is existed between the light-emitting directions of the first light source and the second light source, and the light-emitting directions are parallel to the first substrate portion.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a backlight module and a light source module thereof which can effectively improve the phenomenon of insufficient brightness in the middle area of ​​the liquid crystal display device. Background technique [0002] In recent years, with the continuous development of display technology, Liquid Crystal Display (LCD) is undoubtedly the mainstream of flat panel display technology in terms of mass production scale and product application popularity. In the liquid crystal display, the backlight module that provides the backlight required by the liquid crystal display plays a very important role. [0003] Generally speaking, the backlight module of the liquid crystal display is provided with an LED light-bar (LED light-bar) composed of several light emitting diodes to provide the backlight required by the liquid crystal display. In practical applications, the LEDs on the LED st...
