Abstract
The present invention provides a light guide panel and a backlight module using the light guide panel. The light guide panel is disposed corresponding to a light source module of the backlight module. The light guide panel mainly comprises a plate, a plurality of microstructures and a plurality of protrusions. The plate is disposed close to the light source module and includes a microstructure surface. The microstructures and the protrusions are disposed on the microstructure surface, and the heights of the protrusions are greater than those of the microstructures, and a plurality of the microstructures are disposed between the adjacent protrusions.
Claims36
A light guide panel for a backlight module having an optical element, comprising:
- a plate having a microstructure surface;
- a plurality of microstructures disposed on the microstructure surface;
- and
- a plurality of protrusions disposed on the microstructure surface, wherein heights of the protrusions are greater than those of the microstructures, and more than one microstructure is disposed between the adjacent protrusions, the protrusions are configured to touch against the optical element and a gap exists between the microstructures and the optical element to prevent the microstructures from directly contacting the optical element.
A backlight module, comprising:
- a light source module;
- a light guide panel disposed close to the light source module, the light guide panel comprising:
- a plate having a microstructure surface;
- a plurality of microstructures disposed on the microstructure surface;
- and
- a plurality of protrusions disposed on the microstructure surface, wherein heights of the protrusions are greater than those of the microstructures, and more than one microstructure is disposed between the adjacent protrusions;
- and
- an optical element disposed parallel to the light guide panel, wherein the protrusions touch against the optical element and a gap exists between the microstructures and the optical element to prevent the microstructures from directly contacting the optical element.
