Title:
BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/161669
Kind Code:
A1
Abstract:
A backlight module and a liquid crystal display device. The backlight module comprises: a backlight source structural layer (1); and sequentially disposed on the light emitting side of the backlight source structural layer (1), a first convex lens structural layer (2), a second convex lens structural layer (3) and a prism layer (8). Parallel light rays (4) emitted from the backlight source structural layer (1) are condensed, after passing through the first convex lens structural layer (2), onto the focal point of the second convex lens structural layer (3), and then are converted, after passing through the second convex lens structural layer (3), into parallel light beams (5); the parallel light rays (4) which originally have a uniform surface are converted into the parallel light beams (5) of a condensing state; the parallel light beams (5) further pass through the prism layer (8) to be refracted for multiple times to achieve light splitting, so that light rays having different colors are refracted out; and the light rays having different colors enter sub-pixels of the correspond colors respectively, thereby improving light transmittance; therefore, purposes of increasing energy efficiency utilization rate and reducing product energy consumption are achieved.
