Title:
SPLICING TYPE LIGHT GUIDE PLATE STRUCTURE AND BACKLIGHT MODULE
Document Type and Number:
WIPO Patent Application WO/2012/071749
Kind Code:
A1
Abstract:
A splicing type light guide plate structure (1) and backlight module are provided. The splicing type light guide plate structure (1) comprises at least two light guide plate units (10). Each light guide plate unit (10) comprises a first inclined surface (11) and a second inclined surface (12). Each light guide plate unit is provided with at least one light emitting unit (3). The first inclined surface (11) is set at one side of the light guide plate unit (10). The second inclined surface (12) is set at another side of the light guide plate unit (10) correspondingly. The at least one light emitting unit (3) is set below the first inclined surface (11). In the splicing type light guide plate structure, the light guide plate is formed by splicing the adjacent inclined surfaces, and the inclined surfaces changes the transmission direction of the light ray, so that the problem that the length of the light guide plate is limited can be solved. The splicing type light guide plate structure can be used in large liquid crystal display, and can realize light dimming in different areas.
