Abstract
A method of coating a light emitting diode (LED) is provided. The method includes preparing a substrate in which a plurality of LEDs are arranged, applying a curable liquid containing a fluorescent material to the substrate and the plurality of LEDs, and selectively applying energy to the substrate to which the curable liquid is applied, to thereby pattern the curable liquid, wherein the application of the energy includes applying the energy to both surfaces of the substrate.
Claims11
A method of coating a light emitting diode (LED), comprising:
- preparing a substrate on which a plurality of LEDs are arranged;
- applying a curable liquid containing a fluorescent material onto the substrate and the plurality of LEDs;
- and
- selectively applying energy light to the substrate to which the curable liquid is applied, to thereby pattern the curable liquid, wherein the application of the light includes:
- aligning a first mask on an upper surface of the substrate and a second mask on a lower surface of the substrate, and
- directly applying the light to the upper and lower surfaces of the substrate so that the upper surface is directly exposed to the light through the first mask and the lower surface is directly exposed to the light through the second mask.

A method of coating a light emitting diode (LED), comprising:
- preparing a substrate having a first surface on which a plurality of LEDs are arranged;
- applying a curable liquid containing a fluorescent material onto the first surface of the substrate and the plurality of LEDs;
- directly applying light to the first surface of the substrate through a first mask to pattern the curable liquid on the first surface;
- and
- directly applying the light to a second surface of the substrate which is opposite to the first surface of the substrate through a second mask having a mirror image to the first mask.
