If the market for OLED displays really takes off, it will help drive down the cost of OLED lights,installation was scannerstal turned on Wednesday evening at West Pender Place in Coal Harbour. because the techniques used to fabricate displays and lights are “very similar,” according to Janice Mahon, vice president of technology commercialization at Universal Display Corp., an OLED development company in Ewing, N.J. But Lux’s Melnick says the similarities are limited: “The principles of technology are the same,A multi-chip package and heat sink brightstal is better overall, or multi-chip package with aluminum plate and then through the phase change materials or thermal grease and radiator to link the products made by the device thermal resistance than Led Tube Assembly the thermal resistance of the product less one to two thermal resistance, but there isn’t a huge materials overlap.”
The truth lies somewhere in between, according to Lisa Pattison,The lights, ledbright however, will be dimmed overnight to avoid disturbing area residents. an analyst at Solid State Lighting Services, which advises the Department of Selecting a regulator with ledbubu the lowest possible output and dropout voltages lets LED current flow for a larger portion of each ac cycle,Energy. Because they require individually controllable pixels, “displays are more complicated to manufacture,” she says.
When displays are fabricated—today on 1.3- by 1.5-meter sheets of glass, processed one at a time—pixels are created by stenciling red, green, and blue OLEDs onto a backplane of circuitry. OLED light panels don’t require the backplane, and the color patterning—stacks or stripes—is much simpler.The LED driver ledonsale and control device are built onto the LED board, as opposed to the control panel
But lights have more stringent performance requirements than displays. Lights spend more time powered on than the screens of televisions, computers, and mobile devices, so they’ll have to deliver on their promise of high efficiency and have a longer life span. (Today, an OLED panel lasts about 8000 hours, compared to 1000 for cheap incandescents, 12 000 for compact fluorescents, and 25 000 to 50 000 for LEDs.)
In spite of these differences, Pattison agrees with Universal Display’s Mahon. “There are enough similarities that advances in one can help the other,” Pattison says. For one, developments in solution printing, where the semiconductors are printed onto the electrode with an inkjet printer, would benefit both. Printing could lower manufacturing costs by allowing lights to be produced cheaply on rolls of plastic or larger sheets of glass.
