| Vision into the future of architectural lighting ![]() "Many designers and specifiers wanted to know how long it would take for WAC to integrate OLED technology into viable lighting products," continued Ms. Wang. "They loved the transparency of the panels, the unique quality, the dimmability, the sustainability, and operation without a heat sink. Specifiers touched the panels and were impressed to learn that the fixtures were operating at room temperature. OLED is a flat light source and heat dissipation is more efficient, in contrast to heat accumulation of LED (point-source). The panels are energy efficient, thus they turn energy to light instead of heat." An OLED (Organic Light Emitting Device or Organic Light Emitting Diode) features a thin film display technology that began to appear in cell phones and other small-screen applications in early 2000. OLED screens consist of a series of organic layers between two electrical contacts (electrodes). OLEDs are monolithic, with each layer deposited on the other, creating a single unit. Commonly constructed on glass, OLEDs can also be fabricated on plastic and other flexible films. OLEDs offer bright, colorful images with a wide viewing angle, low power, and high contrast ratio. They can also be made transparent, enabling them to function in heads-up displays and even as window shades that react to sunlight. OLEDs do not need backlights, and screens can be made ultra thin. OLED's color, speed, thinness, transparency and flexibility make it a very versatile display technology. Ms. Wang added, "Using OLED for lighting application is still in the infancy stage. Our research scientists are exploring the technology and anticipating rapid progress in commercial applications, in the years to come." write your comments about the article :: © 2009 Construction News :: home page |
