Title:
METHOD FOR MANUFACTURING BACKLIGHT UNIT
Document Type and Number:
WIPO Patent Application WO/2012/070765
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a backlight unit. The method includes forming one or more reception grooves at a light guide plate, aligning one or more LEDs at positions corresponding to the reception grooves and coupling a PCB thereto, and filling one surface of the light guide plate and the reception grooves with a resin material. Accordingly, it is possible to provide a method for manufacturing a backlight unit, which forms a reception groove in a light guide plate to receive a LED and fills the reception groove with a fluid resin material, thus preventing the damage to the LED caused by the difference between the thermal expansion rates of components such as a light guide plate, a reflection film and a PCB. In particular, it is possible to manufacture a backlight unit that can simplify the manufacturing process by filling a reception groove of a light guide plate with a resin material by a coating process and can efficiently extract and transmit light by the light diffusing, refracting and scattering characteristics of the resin material.
