Passive Matrix Replaces Active OLED Displays

SmartXtend technology, from Dialog Semiconductor Plc (FWB: DLG), enables the use of passive matrix OLED displays rather than LCD or active matrix OLEDs in the main displays of many mobile devices — particularly those offering W-QVGA and QVGA resolution. Passive matrix OLEDs are available at a much lower cost compared to active matrix OLEDs while providing the same advantages in terms of video quality and performance.

The new SmartXtend(TM) technology utilizes a number of innovative design techniques — including a unique multi-line addressing scheme, accurate dynamic current matching, and state-of-the-art power management. SmartXtend(TM) is designed to significantly extend the lifetime of passive matrix OLED displays. It reduces the peak current by up to 30% and power consumption by up to 30% compared to the conventional passive matrix driving scheme.

The SmartXtend(TM) technology is part of a range of advanced display driver technologies available from Dialog Semiconductor for a diverse range of low power mobile applications – from electronic paper displays and MEMS, to active matrix OLEDs. 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.
