Embodiment Construction

[0015] see figure 1 , figure 2 and Figure 5 , which discloses the backlight module 100 provided by the embodiment of the present invention.

[0016] The backlight module 100 includes a light guide film 10 , a light bar 20 and an optical film set 30 . The light guide film 10 is made of ultraviolet curing glue or heat curing glue. The light guide film 10 includes a wedge portion 11 adjacent to the light bar 20 and a flat portion 13 adjacent to the wedge portion 11 . The wedge portion 11 and the flat portion 13 are integrally formed and have a common plane 15 , which is the light emitting surface of the light guide film 10 . The wedge-shaped portion 11 has a light incident surface 110, the light incident surface 110 is perpendicular to the plane 15, and the thickness of the wedge-shaped portion 11 gradually decreases from the light incident surface 110 to the flat plate portion 13 to the thickness of the flat plate portion 13, i.e. The flat plate portion 13 has a uniform t...

Abstract

The invention discloses a backlight module, which comprises a light guide film and a light bar, wherein the light guide film comprises a wedged part and a flat plate part adjacent to the wedged part; the wedged part and the flat plate part have a common plane; the wedged part is provided with a light incident surface which is perpendicular to the plane; the thickness of the wedged part is gradually decreased to that of the flat plate part from the light incident surface to the interior of the light guide film; the light bar comprises a light emergent surface which is closely attached to the light incident surface. The invention also relates to a manufacturing method for the backlight module.

Description

technical field [0001] The invention relates to a backlight module and a manufacturing method of the backlight module. Background technique [0002] In the existing backlight module, the light source, such as LED, is generally placed on the light incident surface side of the light guide film, but there is a gap between the light source and the light incident surface, which is prone to light leakage and reduces the brightness of the backlight module. Contents of the invention [0003] In view of this, it is necessary to provide a backlight module that can reduce or eliminate light leakage. [0004] In view of this, it is also necessary to provide a method for manufacturing the above-mentioned backlight module. [0005] A backlight module, which includes: a light guide film and a light bar, the light guide film includes a wedge-shaped portion and a flat plate portion adjacent to the wedge-shaped portion, the wedge-shaped portion and the flat plate portion have a common plan...
