This week’s EYE on NPI is going to the dogs… Display Visions DOG Mini Graphic LCDs! You know we can’t resist checking out new displays – we’ve always loved adding graphical interfaces to our projects and products.
From the Digi-Key highlights page:
DISPLAY VISIONS’ EA-DOGS102 series graphic LCDs are available in an FSTN positive transflective, STN negative transmissive, and FSTN positive reflective version. These displays have a 2.54 mm pitch and can be soldered directly or plugged into socket strips. Therefore, cumbersome gluing procedures, the need for designing a special mounting device, and error-prone cable connections that may lose contact are no longer a concern.
This LCD family was designed for use in German industry and will have an availability of 15+ years. The extremely efficient ratio of external dimensions to the active display area helps in designing very compact devices. Furthermore, its low-power use [single supply 2.5 V to 3.3 V (typically 250 µA)] makes it ideal for handheld applications.
Note that they don’t come with back-lights by default – so if you want back-lighting you’ll need to get separate LED modules. These LCD’s also don’t have built in touch-screens but you can get a resistive overlay, use like any other resistive touchscreen.
There’s a few options for display type, If you’re not sure of which one you want, there’s a little simulator application available from the EA website that lets you select different types (e.g. blue dye, black+white transflective) and backlight LEDs. There’s also a few demo graphics you can use to gauge what text and graphics will look like on the display.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
