DA8622 WQVGA PMOLED driver
Dialog Semiconductor’s DA8622 is the latest generation of PMOLED drivers including the SmartXtend technology for high resolution PMOLED panels. DA8622 is a passive matrix organic light emitting diode (PMOLED) driver supporting resolutions up to WQVGA (up to 432RGB x 240). DA8622 features the SmartXtend technology. SmartXtend includes a bundle of techniques including a unique multi-line addressing scheme, pre-charge schemes and accurate dynamic current matching. Using these techniques SmartXtend can reduce peak current by up to 30% and reduce the average power consumption of the display by up to 30% at the same brightness. As such, SmartXtend enables PMOLED panels to be used as the high-resolution main display in mobile phones and other portable devices. The DA8622 integrates all important functions required for driving high resolution OLED panels. This includes a dynamic current matching that allows column to column current matching to an accuracy of 0.25%, providing excellent picture uniformity, which is a key attribute in RGB PMOLED panels as resolution and colour depth goes up. An extended set of digital interfaces allows maximum flexibility in the application. DA8622 supports a variety of features interfaces including CPU 8 bits interfaces , I2C, or serial interfaces, as well as 18-bit RGB interface ideal to drive fast moving video data. With integrated oscillator, OTP programmable frame rate, automatic Brightness control and special ultra low standby mode, DA8622 can be optimized use in power sensitive handheld applications. DA8622 is shipped in bare die form with gold bumps. DA8622 is suitable for mounting as chip-on-flex or chip-onglass.
