20140321157 | BACK LIGHT UNIT WITH LIGHT GUIDE PLATE PREVENTING DARK AREA BETWEEN LEDS - A backlight unit with a light guide plate preventing a dark area between LEDs is provided, wherein dark area-preventing patterns may adequately compensate for the brightness in a gap between the LEDs that may be a dark area even under the condition that the gap is relatively large and greater than or equal to the width of an LED and thus, uniform brightness may be obtained without an occurrence of the dark area. Accordingly, the number of the LEDs may decrease and thus, a large-sized backlight unit may be fabricated with a relatively low cost. | 10-30-2014 |
20140301105 | BACK LIGHT UNIT WITH LIGHT GUIDE PLATE PREVENTING DARK AREA BETWEEN LEDS - A backlight unit with a light guide plate preventing the dark area between light emitting diodes (LEDs) is provided, wherein a plurality of dark area-preventing patterns formed on an incidence plane of a light guide plate and having different angles of inclination or different radii of curvature may evenly diffuse lights incident from an LED even under the condition that the gap between the LEDs is relatively broad and greater than or equal to the width of an LED and thus, uniform brightness may be obtained without an occurrence of a dark area. Accordingly, the number of the LEDs may be decreased and the backlight unit may be fabricated with a relatively low cost. | 10-09-2014 |
