Datasheet

Suppliers of displays used in medical electronics must ensure that the devices meet the stringent requirements in this market segment. The most important consideration is reliability followed by the duration of innovation cycles which is considerably different compared with markets such as consumer electronics. Long-term availability is critical for components which are used in medical equipment.

Electronic Assembly has filled this need for many years and has now introduced a new EA DOG series display for medical applications. The 128 x 64 pixel EA DOGL128 graphics display is a new addition to the product line. Seven different LED background lighting options are available. The combination of backlighting variations and 5 different display technologies (STN transmissive and reflective, STN blue, FSTN positive and negative) gives users up to 20 possible designs to choose from. All feature high brightness and contrast.

Designed for use in compact, hand-held devices for medical electronics applications, etc., the state-of-the-art LCD product family with and without backlighting has a number of other advantages:

Extremely compact design, 68 x 51 mm with a 64 x 36 mm viewing area,
Super flat, 2.8 mm without backlighting, 6.5 mm with LED backlighting,
3.0 V – 3.3 V single supply power input,
Typical power consumption only 320 μA while fully operating (white LED backlighting as low as 5 mA),
Serial SPI interface (4-wire),
Fast and easy mounting, pins soldered on PCB.

The backlighting color can be selected. 7 different backlighting options are available: white, yellow/green, green, blue, red, amber and a full-color version. All are extremely bright for excellent readability and have low power consumption.

The EA DOGL128-6 modules will also operate with the EA TOUCH128-2. The 4-wire resistive touch panel has a self-adhesive backing and can be mounted directly onto the display. Electronic Assembly recommends a display with backlighting to ensure good readability when the touch panel is used.

The various design options are available from stock in quantities of one or more, and availability is guaranteed for up to 10 years. An easy to use USB evaluation kit, EA 9780-3USB, is available to support application development. Electronic Assembly developed the kit to speed up commissioning and help users familiarize themselves with the EA DOG displays. Displays are also available in other sizes and dimensions: 4 text versions (1 x 8 - 4 x 20 characters) and seven graphics versions (1.7 – 3.9 inch).
