Light conductive board and the backlight module using same

Abstract

The invention relates to a light guide plate and a backlight module using the light guide plate. And the light guide plate comprises a light incoming surface, a light outgoing surface adjacent to the light incoming surface, and a bottom surface adjacent to the light incoming surface, where the light incoming surface is one side surface of the light guide plate, and the bottom surface is equipped with multiple V-shaped microstructures, two inclines of each V-shaped microstructure each make a same included angle with the bottom surface and the included angle is 45 deg to 55 deg. Thus, it can change light transmission direction of the light guide plate and reduces light leakage, and improves strength and uniformity of light outgoing from the light guide plate. Besides, the invention provides a backlight module improving strength and uniformity of outgoing light.

Description

Technical field [0001] The invention relates to a light guide plate and a backlight module using the light guide plate. Background technique [0002] With the development of digital technology, liquid crystal display products have been widely used in all aspects of daily life. However, the liquid crystal itself does not emit light, and a light source device is required to continuously provide light into the liquid crystal display screen to realize the picture display. In order to better display the picture, the light from the light source device that enters the liquid crystal display screen is required to have a high intensity and be uniformly distributed. [0003] In the prior art, the light source device uses a light guide plate as a part of the backlight module to guide light, and an additional processing method of forming a plurality of concave-convex microstructures on the light guide plate makes the light intensity distribution uniform. [0004] See figure 1 , Is a three-d...

AI Technical Summary

Problems solved by technology

[0008] In order to solve the problem in the prior art that the utilization rate of light passing through the light guide plate is not high and the emitted light is uneven, it is necessary to provide a light guide plate that has a high utilization rate of light passing through the light guide plate and can make the incident light uniformly emerge.
