Circular, high-contrast, ultra-thin, power-saving and stable over a very wide temperature range: The OLED displays of the EA W128128-XR series are ideal for use in compact handheld devices.
The dimensions
The new OLED displays from ELECTRONIC ASSEMBLY are only 2.05 mm thick. Their display area has a diameter of 30 mm (1.2″) and consists of a passive matrix of 128 x 128 pixels. This format is ideal for displaying analog measurement scales. The external dimensions of the entire module, including the connection cable, are almost 37 x 41 mm.
The brilliant display technology
As a self-luminous display technology, OLEDs have numerous advantages over LCDs. In addition to its extremely flat design, these include very wide viewing angles of up to almost 180°. Thanks to the low black level, it impresses with a contrast ratio of >2000:1. The brightness of the controlled surfaces in the 50% chessboard pattern is 80 cd/m2.
This sounds little, but is brilliant even in bright daylight. At 10 µs, the display reacts extremely quickly, even at ice-cold -40 °C and still searing +80 °C. The integrated SSD1327ZB controller requires a supply voltage of 3.3 V, and the display 14.5 V. The SSD1327ZB controller is also equipped with a power supply.
The current consumption for displaying a checkerboard pattern is typically 24 mA. The display is controlled via SPI protocol via a 24-pole ZIFF connection. Thanks to numerous initialization examples, measured values, graphics and icons can be displayed quickly and with high contrast.
Which versions are available?
The EA W128128-XR displays are available in three colours: EA W128128-XRLG with yellow, EA W128128-XRLW with white and EA W128128-XRLB with blue pixels on a black background. The typical service life of the yellow display is 50,000 hours. For white and blue, it usually takes 20,000 hours before their brightness is halved.
Briefly summarized
Thanks to its compact design, power-saving display and extreme temperature stability, the EA W128128-XR series is ideally suited for use in mobile handheld devices. OLED simulation software for Windows available for download on the manufacturer’s website for quick testing of your own applications. High contrast and ultra-thin. The new OLED displays from ELECTRONIC ASSEMBLY are ideal for displaying analog measurement scales.
