Abstract
A multi-reflecting Light device includes a plurality of double reflecting surfaces formed serially on the rear of a light guide plate having a taper shape. A light incident upon the light guide plate is double-reflected, and progress in a desired direction. The multi-reflecting structure is applied to a backlight unit and a display device so that the backlight unit and the display device can be slimmer economically.
Claims24
A multi-reflecting device comprising:
- at least one or more light guide plates configured to supply a light emitted from a light emitting unit to a front surface of a liquid crystal panel;
- and
- at least one or more reflecting plates formed on rear surfaces of the light guide plates respectively, each of the reflecting plates having at least one or more reflecting surface configured to multi-reflect a light incident upon the corresponding light guide plates from the light emitting unit and project the multi-reflected light into the front surface of the liquid crystal panel.
A backlight unit having a multi-reflecting structure, the unit comprising:
- at least one or more light emitting units configured to emit a light;
- at least one or more light guide plates, corresponding one by one to the light emitting units, configured to supply a light emitted from the corresponding light emitting unit to a front surface of a liquid crystal panel;
- and
- at least one or more reflecting plates formed on rear surfaces of the light guide plates respectively, each of the reflecting plates having at least one or more multi-reflecting surfaces configured to multi-reflect a light which is incident upon the corresponding light guide plate from the light emitting unit and project the multi-reflected light into the front surface of the liquid crystal panel.
