Patent ID: 10141481

Abstract:
The present invention relates to a color-converting substrate of a light-emitting diode and a method for producing same, and more specifically to a color-conversion substrate of a light-emitting diode capable of completely protecting the quantum dots (QDs) supported in the interior from the exterior as hermetic sealing is possible, and a method for producing the color-converting substrate. To that end, provided are a color-conversion substrate of a light-emitting diode and a method for producing same, the color-conversion substrate of a light-emitting diode comprising: a first substrate arranged on a light-emitting diode; a second substrate disposed facing the first substrate; a first sealing material disposed on the upper surface of the first substrate so as to section a grooved accommodating space having the first substrate as the bottom surface thereof; QDs filling the accommodating space; and a second sealing material, disposed between the second substrate and the first sealing material, having a shape corresponding to the first sealing material, wherein the second sealing material is made of material having a comparatively higher laser absorption rate in the infrared region than that of the first sealing material.
