Light guide plate and back light module

Abstract

The invention provides a light guide plate and a back light module using the same. The light guide plate is formed by the connection of multiple sub-light guide plates by hinge structures, wherein the contact surface of each sub-light guide plate is designed into a concave-convex matching cambered surface structure to enable the whole light guide plate to be bent to a certain extent along the cambered surfaces. Therefore, the light guide plate and the back light module have the advantage of large bending amplitude and are not influenced by the dimension.

Description

technical field [0001] The invention relates to a light guide plate and a backlight module with the light guide plate, in particular to a combined light guide plate and the backlight module with the light guide plate. Background technique [0002] With the development of digital technology, liquid crystal display products have been widely used in various aspects of daily life, and the quality requirements for liquid crystal display (Liquid Crystal Display, LCD) screens are gradually increasing. However, the liquid crystal itself does not emit light, and a light source needs to continuously provide light to enter the display screen to realize image display. In liquid crystal display products, a backlight module is usually selected to provide light. [0003] Such as Figures 1A-1B as shown, Figure 1A It is a schematic side view structure of an existing backlight module, Figure 1B yes Figure 1A A schematic top view of the backlight module shown. The backlight module (Bac...

Problems solved by technology

However, due to technical limitations, this kind of integrated flexible light guide plate cannot be applied to large-sized BLUs, and it cannot be bent by a large margin, otherwise, a large loss of luminance will occur.
