The displays of the DOG family of Electronic Assembly are characterised by a number of distinctive features: they are versatile, extraordinarily compact and consume very low energy. Electronic Assembly has now expanded this family of products with multi-coloured lighting. The signal colors can be mixed and changed.
The display modules of the series DOGM240-6 offer a resolution of 240 × 64 pixels which can generate eight lines with 40 characters each or 4 lines with 20 large characters each. And of course, the displays’ full-graphic mode allows a mix of text and pictures to be displayed. The particularly compact construction of these display modules can be attributed to their high level of integration: the modules contain a UC1611s type controller and the graphic RAM is already integrated. For a high-contrast image pick a LCD-Supertwist or a FSTN display. There are four different LED backlight options available to choose from: amber, white and two-color green/red, as well as the brand-new three-color white/red/green option. The last option is suitable for signalling the equipment status at a glance: White = normal status, Red = error, Green = setup OK. The color white is not mixed, rather it is produced by true white LEDs. By doing this, the backlight provides a bright and neutral white. And last but not least, this module is extremely energy-efficient.
For the operation of the modules, a power supply of between 2.7 and 3.3V is required. The current consumption is typically 500µA for the display. For optimal LED lighting a further 10 to 150mA is enough. Driving the display, customers can choose between the most common interfaces in this application segment: 3-wire SPI, 4-wire SPI and I2C. Thanks to their design, which is providing pins, the displays can be directly soldered into the pcb board without any complicated assembly process. With their ability to operate in a wide range of temperatures, from -20 to +70°C, the displays are suitable for industrial use in harsh environments. In terms of accessories, a USB test board 9780-3 and a free Windows simulator are available, as well as an attachable touch panel and the relating ZIF connector. The long-term availability is generously measured as 10 years, even for demanding projects.
