Light guide plate with V-shaped structures and backlight module comprising same

Abstract

The invention relates to a light guide plate with V-shaped structures and a backlight module comprising the same. The light guide plate comprises a substrate and a plurality of straight strip V-shaped structure groups, wherein the substrate comprises a first side surface and a second side surface opposite to the first side surface, wherein the first side surface is an incidence plane; each straight strip V-shaped structure group comprises at least one V-shaped component; the two inclined planes of each V-shaped component and the horizontal plane of the substrate form a first base angle and a second base angle; the first base angle is closer to the first side surface than the second base angle; the straight strip V-shaped structure groups respectively have a plurality of average values of the first base angles, a plurality of average values of the second base angles and a plurality of average values of the minimum base angles; the plurality of the straight strip V-shaped structure groups comprise a first V-shaped structure group and a second V-shaped structure group, wherein the second V-shaped structure group is positioned between the first side surface and the first V-shaped structure group; and the average value of the minimum base angles of the first V-shaped structure group is less than the average value of the minimum base angles of the second V-shaped structure group.

Description

[0001] This application is a divisional application of an invention patent application with an application date of March 2, 2009, an application number of 200910004678.6, and an invention title of "Light guide plate with V-shaped structure and backlight module including the light guide plate". technical field [0002] The invention relates to a light guide plate and a backlight module, in particular to a light guide plate with a mixed V-shaped structure and a backlight module including the light guide plate. Background technique [0003] The backlight module is one of the key components of the liquid crystal display panel. Since the liquid crystal itself does not emit light, it is necessary to use a backlight module to provide a light source so that the liquid crystal display panel can display normal images with uniform brightness. A backlight module usually includes a light source, a light guide plate, and multiple optical films located above the light guide plate, such as ...

AI Technical Summary

Problems solved by technology

Therefore, the light-emitting light type of the known light guide plate is difficult to produce consistent light incident angles in the front, middle and rear areas of the light guide plate, and thus cannot meet the optimal light incident angle of the optical film.
