Light control technique could lead to tunable lighting and displays

(PhysOrg.com) — Over the past several years, organic light-emitting diodes (OLEDs) have become a popular light source due to their advantages including bright displays, wide viewing angles, and the ability to be printed on flexible substrates. A lesser known alternative to OLEDs, which has these advantages plus some additional ones such as low turn-on voltage, is electrochemical light-emitting cells (LECs).
