Title: LIGHT GUIDE PLATE, BACKLIGHT MODULE, AND DOUBLE-SURFACE DISPLAY DEVICE
Abstract:
A light guide plate, a backlight module, and a double-surface display device. The light guide plate comprises a light inlet surface (11), a first light-exit surface (12), and a second light-exit surface (13). The first light-exit surface (12) is used for guiding partial light in the light guide plate for making the partial light be emitted out of the first light-exit surface (12), and the light emitted out of the first light-exit surface (12) provides a first light source to a first display screen in the double-surface display device. The second light-exit surface (13) is disposed oppositely to the first light-exit surface (12) and is used for guiding the other partial light in the light guide plate for making the other partial light be emitted out of the second light-exit surface (13), and the light emitted out of the second light-exit surface (13) provides a second light source to a second display screen in the double-surface display device. Each of the first light-exit surface (12) and the second light-exit surface (3) is provided with multiple prism micro-structures (14) and multiple dot micro-structures (15) to improve the brightness of the light emitted out of the first light-exit surface (12) and the second light-exit surface (13). In this way, the double-surface display device is lighter and thinner.
