Abstract
A light guide plate includes a light incident face, a bottom face adjacent to the light incident face and a light exit face opposite to the bottom face. The micro lenses are formed on the light incident face in series to diffuse light incident thereon. Two adjacent micro lenses cooperatively define a V-shaped groove therebetween. Each groove defines an opening. The width of the openings of the grooves gradually changes from a center of the light incident face toward lateral sides thereof. A backlight module incorporating the light guide plate is also provided.
Claims20
A light guide plate comprising:
- a light incident face;
- a bottom face adjacent to the light incident face;
- and
- a light exit face adjacent to the light incident face and opposite to the bottom face;
- wherein a plurality of micro lenses are formed on the light incident face in series to diffuse light incident thereon, and every two adjacent micro lenses cooperatively define a V-shaped groove therebetween;
- and
- wherein each groove defines an opening, and the width of the openings of the grooves gradually changes from a center of the light incident face toward lateral sides thereof
A backlight module comprising:
- at least one LED light source;
- and
- a light guide plate coupled to the at least one LED light source, and the guide plate comprising a light incident face, a bottom face adjacent to the light incident face and a light exit face adjacent to the light incident face and opposite to the bottom face;
- wherein a plurality of micro lenses are formed on the light incident face in series to diffuse light incident thereon, and every two adjacent micro lenses cooperatively define a groove therebetween, each groove defining an opening, the width of the openings of the grooves gradually changing from a center of the light incident face toward lateral sides thereof;
- and
- wherein the at least one LED light source faces the light incident face of the light guide plate.
A light guide plate comprising:
- a light incident face;
- a bottom face adjacent to the light incident face;
- and
- a light exit face adjacent to the light incident face and opposite to the bottom face;
- wherein a plurality of micro lenses are formed on the light incident face in series to diffuse light incident thereon, each micro lens comprises two opposite inclined side surfaces, and an inclined side surface of the micro lens and a neighboring inclined side surface of an adjacent micro lens cooperatively define an angle therebetween;
- and
- wherein the angles defined between two adjacent micro lenses of the plurality of micro lenses gradually change from a center of the light incident face toward the lateral sides thereof.
