Title:
LIGHT GUIDE FILM, BACKLIGHT MODULE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/028457
Kind Code:
A1
Abstract:
A light guide film (3), comprising a substrate (31) having main surface (311), and a light guide plastic material (32) provided along an edge of the substrate (31), on the main surface (311), and extending at an angle towards the main surface (311), wherein, the refractive index of the light guide plastic material (32) is different from the refractive index of the substrate (31), such that a light ray from the substrate (31) and incident on the light guide plastic material (32) can undergo total internal reflection and once again return to the inside of the substrate (31), thus realizing a light-loss prevention effect. The light guide film (3) is for a backlight module and is installed on a display device, and can fully utilize a light ray emitted by a light source (4), optimizing display quality of the display device.
