Title:
LED PANEL USING SEMICONDUCTOR LIGHT-EMITTING ELEMENT, PRODUCTION METHOD THEREFOR, AND DISPLAY DEVICE COMPRISING LED PANEL
Document Type and Number:
WIPO Patent Application WO/2023/243782
Kind Code:
A1
Abstract:
This LED panel comprising: a base substrate including circuit wiring; a plurality of light-emitting diodes disposed to form an array on the base substrate; a side optical layer located laterally to the plurality of light-emitting diodes and including a diffusing agent; and a plurality of upper optical layers respectively located on top of the plurality of light-emitting diodes and including a diffusing agent can provide uniform light in all directions through uniform light distribution by reducing color difference for different viewing angles that occurs due to the structure of a semiconductor light-emitting diode.
