Aug. 10, 2010. The invention is related to the invention. [0001] The present invention relates to a light guide plate and a backlight module having the same. [Prior Art] [0002] Since the liquid crystal of the liquid crystal display panel itself does not have the illuminating property, in order to achieve the display effect, the liquid crystal display panel is provided with a light source, such as a backlight module, which functions as a liquid crystal display panel. A surface light source with sufficient brightness and uniform distribution is supplied. [0003] The backlight module of the prior art is mainly composed of a light source, a light guide plate, a reflection plate, a diffusion plate and a prism plate. The light source may be disposed on one side or two opposite sides of the light guide plate and emit a light beam to the light guide plate. The light guide plate is configured to guide the beam transmission direction so that the light beam is uniformly emitted from the light exit surface of the light guide plate, and the reflector plate is disposed opposite to the bottom surface of the light guide plate to reflect the light beam emitted from the bottom surface of the light guide plate into the light guide plate again. The utilization of the beam. The diffusing plate and the prism plate are arranged in sequence with respect to the light-emitting surface of the light guide plate, so that the light beam emitted from the light guide plate is more evenly distributed, thereby improving the brightness and uniformity of the liquid crystal display panel. [0004] Since the light-emitting diode has the advantages of low operating voltage, high luminance, fast response speed, and long life, it is widely used in mobile phones, pda (personal digital assistants), and backlight modules of displays. However, the light emitted by the light-emitting diode has a strong optical directivity, that is, the emitted light has a certain divergence angle. When it is directly incident on the light guide plate of the backlight module, the light-emitting plate is easily exposed to the light-incident side. In the dark region, and the position opposite to the light-emitting diode is prone to appear light column, it is difficult to obtain better uniformity of light entering.

The light beam of the plurality of light emitting diodes enters the light guide plate 13 from the light incident surface 131 of the light guide plate 13 and is disposed on the light guide plate. Reflection occurred within 13. The light guide plate 13 guides the light source 12 to emit a light beam, and converts it into planar light to be emitted from the light exit surface 132 of the light guide plate 13. However, since the emitted light of the light-emitting diode has a certain divergence angle, the optical dark area 15 and the light column 16 appear on the light-emitting surface 131 side of the light guide plate 13, and the optical dark area 15 is mainly distributed in two adjacent light-emitting diodes. The position of the light column 16 is opposite to the position of the light guide plate 13 facing the light emitting diode, which affects the brightness and uniformity of the light output of the backlight module 10. In view of the above, it is necessary to provide a light guide plate that can uniformly emit light, and a backlight module with uniform luminance. SUMMARY OF THE INVENTION [0007] Hereinafter, a light guide plate that can uniformly emit light by effectively adjusting incident light, and a backlight module having the light guide plate will be described by way of embodiments.
