    • 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.
    • 用于封装光学元件的光发射单元的方法和设备技术领域本发明涉及用于封装光学元件的光发射单元的方法和设备,并且更具体地涉及用于封装光发射单元的方法和设备,所述方法和设备包括形成用于封装部分 或者具有所述受光部或者所述发光部的光学元件的受光部或者发光部的周边整体,其特征在于,所述光发送部的封装方法包括: 制备其中多个光学元件排列在平面上的光学元件阵列; 准备具有对应于各个光学元件的图像单元的屏幕的步骤; 以及通过丝网丝网印刷处于真空状态的光透射树脂以形成光发射单元的步骤。 如上所述,本发明的方法包括实施真空丝网印刷工艺以在大面积的衬底(特别是,衬底施加的)上形成均匀的有机膜(即,圆顶形的光透射单元) 在制造用于由LED组成的LCD的BLU时),从而缩短处理时间,最小化光发射单元中的孔隙的产生,并且形成具有更少孔隙的光透射单元,即使当 根据屏幕和图案的网格,光发射单元可以具有各种形状。 因此,透光单元的形成使得能够控制光提取效率和光的扩散率,由此获得具有均匀光特性的光学元件。
