Abstract
A backlight module includes a back cover, a light source located on the back cover, an optical fiber located on the back cover and over the light source and having a light-incident hole facing the light source and a plurality of light-emergent windows opposite to the light-incident hole. A plurality of light shutters correspondingly covers the light-emergent windows. A controlling device is provided for controlling the open and close of the light shutters. Light emitted from the light source and entering the optical fiber is permitted to leave the optical fiber from the light-emergent windows whose light shutters are opened. The light is not permitted to leave the optical fiber from the light-emergent windows whose light shutters are closed.
Claims19
A backlight module comprising:
- a back cover;
- a light source located in the back cover;
- an optical fiber located on the back cover and over the light source, the optical fiber having a light-incident hole facing the light source and a plurality of light-emergent windows opposite to the light-incident hole;
- a plurality of light shutters correspondingly covering the light-emergent windows;
- and
- a controlling device being configured for controlling the light shutters to open or close, wherein light emitted from the light source and entering the optical fiber is permitted to leave the optical fiber via the light-emergent windows whose light shutters are opened and not permitted to leave the optical fiber via the light-emergent windows whose light shutters are closed, a bottom face of the optical fiber is attached on a top face of the back cover and correspondingly faces the light source.
A backlight module comprising:
- a back cover;
- a plurality of light sources located on the back cover;
- an optical fiber located on the light source, the optical fiber having a plurality of light-incident holes correspondingly facing the light sources and a plurality of light-emergent windows opposite to the light-incident holes;
- a plurality of light shutters correspondingly covering the light-emergent windows;
- and
- a controlling device being configured for controlling the light shutters to open or close, wherein light emitted from the light sources and entering the optical fiber is permitted to leave the optical fiber via the light-emergent windows whose light shutters are opened and not permitted to leave the optical fiber via the light-emergent windows whose light shutters are closed, each light source has a specific light wavelength range to emit a light with a predetermined color, whereby a mixture of the lights with different wave lengths is obtained in the optical fiber.
A backlight module comprising:
- an optical fiber on the back cover, the optical fiber having a plurality of light-emergent windows;
- a plurality of light sources covered by the optical fiber whereby light generated by the light sources enters the optical fiber;
- a plurality of light shutters correspondingly covering the light-emergent windows;
- and
- a controlling device being configured for controlling the light shutters to open or close, wherein light emitted from the light sources and entering the optical fiber is permitted to leave the optical fiber via the light-emergent windows whose light shutters are opened and not permitted to leave the optical fiber via the light-emergent windows whose light shutters are closed, a bottom face of the optical fiber is attached on a top face of the back cover and correspondingly faces the light source.
