Abstract

The present invention relates to a method and apparatus for packaging a light-transmitting unit for an optical element, and more particularly, to a method and apparatus for packaging a light-transmitting unit, which involve forming a light-transmitting unit for encapsulating a portion or the entirety of a periphery of a light-receiving unit or a light-emitting unit for an optical element having the light-receiving unit or the light-emitting unit, wherein the method for packaging a light-transmitting unit comprises: a step of preparing an optical element array in which a plurality of optical elements are arranged on a plane; a step of preparing a screen having image units corresponding to the respective optical elements; and a step of screen-printing a light-transmitting resin in a vacuum state through the screen to form the light-transmitting unit. As described above, the method of the present invention involves implementing a vacuum screen-printing process to form a uniform organic film (i.e., a dome-shaped light-transmitting unit) on a substrate with a large area (in particular, a substrate applied in fabricating a BLU for an LCD consisting of LEDs) in a short amount of time, to thereby shorten a process time, minimize the generation of pores in the light-transmitting unit, and form the light-transmitting unit with fewer pores even when the light-transmitting unit may have various shapes in accordance with meshes of the screen and patterns. Accordingly, the formation of the light-transmitting unit enables light extraction efficiency and the diffusivity of light to be controlled, thereby obtaining optical elements with uniform light characteristics.
