LG Display Exhibited “Rugged” OLED Panel

At SID Display Week 2009, LG Display Co Ltd of Korea exhibited a “rugged” 15-inch OLED panel. And the company had surprised the visitors by showing a demonstration video in which the panel was repeatedly being hit with a mallet to prove its toughness.

"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.

The ultra-thin OLED panel measures 347.94 x 209.80 x 0.85mm and 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 of the panel is 120Hz.

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

The words "rugged" and "ruggedized," which mean tough or less breakable, were seen everywhere at this year's SID. They will probably become more generally used as more and more displays are becoming flexible.
