Backlight module and manufacturing method of the same

摘要

An exemplary backlight module includes a light guide film and a light bar. The light guide film includes a top surface, a bottom surface, and a light incident surface connected between the top surface and the bottom surface. The light bar includes a light-emitting surface. The light-emitting surface is attached to the light incident surface. A method for manufacturing the backlight module is also provided.

主权项

1. A method for manufacturing a backlight module, comprising:
providing a mold apparatus and a light bar, the light bar comprising a light emitting surface, the mold apparatus comprising a lower mold and an upper mold, the lower mold comprising a first mold sub-cavity and a second mold sub-cavity communicating with the first mold sub-cavity, the first mold sub-cavity comprising a side surface and receiving the light bar, with the light emitting surface of the light bar being parallel to the side surface; providing an amount of melted resin in the second mold sub-cavity, the melted resin flowing and contacting the light emitting surface; closing the upper mold and the lower mold; and curing the resin to thereby obtain a light guide film, the light guide film comprising a top surface, a bottom surface, and a light incident surface connecting the top surface and the bottom surface, the light incident surface being directly attached to the light emitting surface.
