EYE on NPI – Display Visions DOGS102N-6 Display #EyeOnNPI #DigiKey @DigiKey @Adafruit: A New video by Adafruit Industries

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.

We’ve seen some DOG displays before, they were used in the Pimoroni Display-o-Tron HAT (https://ift.tt/2kFZnKw) – you can tell these by their distinctive mounting style. Unlike common LCD modules which are pretty chunky (https://ift.tt/2veB2lF), these are slim and svelte with direct mounting pins that are bonded onto the LCD glass so you can selective solder them without extra hand-labor.

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. (https://ift.tt/2PvyaM7). These LCD’s also don’t have built in touch-screens, but you can get a resistive overlay to use like any other resistive touchscreen (https://ift.tt/3fxVTG5)

These displays happen to have a UC1701 controller chip, for which we found a couple easy-to-use Arduino code libraries. (https://ift.tt/2C6CDSu) We loaded one of the u8g2 examples onto an ItsyBitsy and had it displaying in a few minutes! You just need SPI plus a few controller pins – no high voltage booster required.

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 (https://ift.tt/3a3kwJC) 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.
