LG Display Intensifies OLED Lighting Push

LG Display continues to promote OLED TV technology, but has also been making a major statement in the OLED lighting market, with mass production commencing at its new Gen 5 OLED light-panel line in Gumi, Korea, and the introduction of a new OLED light brand, Luflex. According to LG, the Gen 5 line (1,100 mm × 1,250 mm) has been producing about 15,000 sheets per month, an approximately 30-fold increase compared to the company’s previous Gen 2 line (370 mm × 470 mm), with a monthly capacity of 4,000 sheets.

The company’s new Luflex brand name is derived from “lux” (light in Latin) and “flexibility,” reflecting OLED’s flexible, bendable, and rollable characteristics. The OLED light panels are very slim (0.41 mm thick), and their flexibility allows them to be fabricated in a variety of shapes, including curves or spirals. OLED lighting panels have already been adopted for experimental applications by world-famous industrial designers including Ron Arad and Ross Lovegrove. LG Display has also started mass production of OLED tail lights for automobiles.

As a lighting source, OLED is considered to be easier on the eyes than conventional sources such as fluorescent and LED, as it offers great uniformity in its luminescence. It also exhibits very little temperature rise under normal conditions, meaning that it can be used to illuminate, for example, food displays or antique wooden furniture or buildings.

For the past five years, LG Display has hosted the international LG OLED Design Competition, a platform for designers and architects to incorporate OLED lighting into their designs. The 2017 competition focused on creative uses for LG Display’s 0.41-mm thick panels with a bending radius of 20 mm, and winners were announced in the categories of Lighting Design and Space Design. -- Jenny Donelan
