    摘要: A light guide plate and a plane light source unit are provided. The light guide plate for a plane light source unit includes a plurality of unit pattern regions each having a plurality of optical patterns on surfaces thereof, wherein one or more unit pattern regions have different sag values (height:lens size) of the optical patterns constituting the unit pattern regions. Unit pattern regions are implemented with segmented optical patterns, which are equal in height, from the outside of the light guide plate to the central part thereof, by adjusting the density and size of microlenses, thereby improving the light uniformity and light efficiency and improving the efficiency of manufacturing processes.

    摘要: The present invention relates to a backlight unit with sag control patterns, comprising a light source formed in a side surface of a light guide plate; and a plurality of optical patterns formed on a lower surface of the light guide plate, sag of the plurality of optical patterns increasing as the optical patterns become more distant from the light source. By controlling sag of optical patterns formed in a light guide plate, efficiency of light emitted from a backlight unit can be improved and uniformity of the light can be maintained. Also, since sag of optical patterns can be controlled, by increasing the number of optical patterns (by improving fill factor), light efficiency and uniformity can be controlled easily. Also, compared with a conventional method for manufacturing white dot patterns, white dot patterns can be more efficiently manufactured in terms of development time and costs.
