Dialog Semi to bring PMOLED displays to mobiles

Dialog Semiconductor Plc has introduced it SmartXtend technology that will allow the main displays of many mobile devicesparticularly those offering W-QVGA and QVGA resolutionto use passive-matrix OLED (PMOLED) displays rather than LCD or active-matrix OLEDs (AMOLEDs).

PMOLEDs are available at a much lower cost compared to AMOLEDs while providing the same advantages in terms of video quality and performance.

The SmartXtend technology uses multiline addressing scheme, accurate dynamic current matching and art power management. The technology will form the basis of a new family of display drivers to be developed by Dialog for PMOLEDs. SmartXtend is designed to significantly extend the lifetime of PMOLED displays; it reduces the peak current by up to 30 percent and power consumption by up to 30 percent compared to the conventional passive matrix driving scheme.

"As OLEDs increasingly replace active- or passive-matrix LCD displays, we believe SmartXtend allows Dialog to develop a roadmap of products that give mobile device manufacturers an alternative to the current trend of using active-matrix OLEDS in the primary display," said Manoj Thanigasalam, general manager of Dialog's displays system business unit. "SmartXtend, which is being evaluated by a number of our customers, will allow the use of lower-power and lower-cost passive-matrix OLEDs to be extended to higher resolution main displays on mobile devices."

The SmartXtend technology is part of a range of display driver technologies available from Dialog for a diverse range of low-power mobile applicationsfrom electronic paper displays and MEMS, to AMOLEDs. All its display drivers are highly integrated mixed-signal high-voltage CMOS solutions designed for the next generation of always-on low power displays, available as both standard and custom products.
