LG Display Co Ltd of Korea exhibited a 15-inch OLED panel at SID Display Week 2009. To highlight its toughness, the company showed a demonstration video of the panel being hammered with a mallet.

The OLED panel has a thin profile, measuring only 347.94 x 209.80 x 0.85mm. It has 1,366 x RGB x 768 pixels with a resolution of 105 pixels per inch (ppi). The average luminance is 200cd/m2, and the contrast ratio is 100,000:1. The frame frequency is 120Hz.

What surprised visitors most is that the panel was repeatedly being hit with a mallet in the demonstration movie.

"We formed an OLED layer on a glass substrate and provided a steel sheet on its back side and a resin sealing layer on the front, making the panel durable to shock," LG Display said.

However, the panel is not flexible because of the glass substrate, the company said.

The terms "rugged" and "ruggedized," which mean tough or less breakable, were ones of the keywords at this year's SID. They will probably become more familiar words as more and more displays are becoming flexible.
