Samsung announced that its new, broad 256-channel display driver IC (DDI) for plasma display panels (PDP) is in mass production. This new DDI offers a lower power consumption rate over conventional PDP driver ICs, and creates greater cost efficiencies by reducing the number of DDIs per panel.
First introduced in the 192-channel DDI, Samsung’s power-saving technology, an energy recovery circuit (ERC), is again implemented in the new 256-channel driver IC to recycle energy loss within the circuit. This new power-smart feature lowers the DDI power consumption of a conventional PDP TV by over 35 percent. Such a reduction in power eliminates the need for a separate power-saving component feature, enabling for a slimmer and lighter TV module.
Moreover, an increase in the number of channels covered per chip reduces the number of DDIs required per panel. Twelve 256-channel DDIs can now replace the sixteen 192-channel DDIs previously needed to achieve the same low power consumption in a full high definition 40-inch PDP,.
According to the market forecast firm Display Search, the demand for 40” and larger PDP screens is expected to grow at a compound annual growth rate of 20 percent, from 12.25 million units in 2007 to 18.84 million units in 2010.No tag for this post.
