Univision, available through GLYN High-Tech Distribution, has introduced a new low cost, 0.85” diagonal screen size, monochrome (light blue) OLED module (part number UG-0416ALBAG01). With a resolution of 104 x 16 pixels, Univision continues to widen its OLED display product range that will revolutionise small user interfaces.
The optical clarity of this tiny display, with a panel size of just 31.30 x 9.20 x 1.85mm, an active area of 21.305 x 3.28mm, and a pixel size of 0.19 x 0.19mm makes it ideal for a wide variety of applications, where readability in a small form factor is required.
With a dark room contrast ratio of over 1:100 (typical), brightness at 60cd/m² (typical, with polarizer), viewing angles of over 160° and ultra fast response times (2.5us minimum clock cycle) allowing motion video, those yellow green character displays of the past can be replaced with the new OLED display technology from today.
The SSD0300Z controller with built-in driver used in this OLED module can communicate with an external MCU using I2C protocol. An 8-pin module interface is provided for the I2C bus, power supply pins, reset, and current reference resistor.
Vdd supply voltage can range from 2.6 to 3.5V (2.8V typical), while the Vcc driver supply voltage can range from 6.5 to 7.5V (7V typical). Idd operating current is 95uA (typical), while Icc operating current is 2mA (typical) with 50% of the display turned on, making it suitable for low power applications.
While OLEDs have been accepted as having superior optical qualities than alternative technologies such as LCDs, factors such as lifetime, price and operating temperature have limited their applications in the past. Dramatic improvement in OLED process technology overcomes these problems and this display has an average operating half life of 10,000 hours at room temperature, and an operating temperature at -30° to +70°C, with prices competitive over LCD technologies.
An evaluation kit and sample codes are also available for easier product evaluation and development. This OLED module is ideally suited for a wide range of applications such as audio and consumer electronic equipment, measurement equipment, caller ID telephone, handheld radio, and other portable devices.
