Welcome to Display Devices and Materials Lab. in SKKU


D.D.M. Lab. was founded in 2010 and has been led by Prof. Jang-Kun Song.


Our research areas include:


Liquid Crystals

Material properties and electro-optic properties of Liquid Crystal (LC)

Topological structures and interface phenomena in LC mircrodroplets

Multi-directional dielectrophoresis (MDEP) in nematic liquid crystal medium

Manipulation of nanoparticles and fabrication of nanoparticle array


2D Materials

Fabrication of photonic crystals with colloidal 2D materials and its fundamental study  

Graphene, Graphene Oxide (GO), and its application


Quantum Dot Light-Emitting Diodes

Design of quantum-dot light-emitting diode device structures


Optical vortex for next-generation optical communications and autostereoscopic displays

Micro-lens array for high transmittance polarizer and anti-relection structure


Energy Harvesting

Design of energy harvesting system with triboelecricity



Synthesis of novel materials for supercapacitors


We welcome all undergraduate students who have an interest in these fields.
