Low-power displays for flat mobile devices
The EA DOG series of flat display modules from DISPLAY VISIONS is designed specifically for applications where low energy consumption and a compact design are important. This makes this display series ideal for use in battery-powered handheld devices.
The displays work with single supply 3.3 V as standard and require only 150-350 µA, which makes them ideal for use in mobile and battery-powered devices. A power-down mode brings it more down to 2 µA. The optional LED backlight is also designed for 3.3 V and is satisfied with low currents from 3 mA.
The overall height of the display units without the backlight is just 2 mm; with lighting a maximum of 5.8 mm. This makes the modules suitable for designs where space is severely limited. They can be soldered directly to printed circuit boards in 2.54 mm pitch, without the need for additional sockets.
The displays are available in ten sizes, as text or graphic variants. There are five different display technologies to choose from: STN (reflective, transmissive, blue) and FSTN (positive or negative). Numerous design options are available, in combination with six separately available LED lights (white, amber, blue, red, yellow/green and RGB). This makes it easy to combine display units with a maximum overall height of 5.8 mm.
Text displays are available in 1×8, 2×16, 4×10 (switchable to 2×10), 4×16 and 4×20 characters. Individual variants support multiple character sets simultaneously, including English, Western European and Cyrillic. The graphics displays are available in five resolutions between 122×32 and 240×128 pixels. The module sizes are between 39×41 mm and 94×67 mm.
All displays have an SPI interface. In addition, the text displays offer a 4-/8-bit interface, certain models also support I²C. Thanks to the integrated temperature compensation, the modules can be used in a wide temperature range from -20°C to +70°C.
For easy system entry and rapid development, there is a USB test board with PC connection and associated Windows software and free simulator. Numerous C and microcontroller code examples are also available.
The EA DOG series boasts long-term availability of up to ten years and is delivered in quantities of 1 and above.
