The new EA 9781-1USB evaluation board provides rapid development start with the EA OLED displays. The evaluation board powers all the EA OLED display modules including the round EA W128128-X. Download the free PC software StartOLED.exe, install the software and connect the USB cable to the evaluation board and extremely quickly and with minimum expense your graphics and text are shown on the display. The EA 9781-1USB board comes with an arrangement of plug contacts to suit all the OLED display modules. No other hardware components – such as adapters, driver boards, power supplies or the like – are required. This software is available free of charge on the OLED page and can be used even without a test board, which means that text and bitmap graphics for the display modules can be displayed directly. This screen content is loaded onto the test board and displayed. Use of the program is largely self-explanatory and does not require any knowledge of software.

Round, square or very small OLED displays with wide viewing angle and high contrast open up new applications. The OLED displays offer low current, compact module size and extreme wide operating temperature of -40..+80°C. Never before was it possible to use a display at -40°C without adding additional environmental protection and still be able to read the display with quickly changing content. The convenient serial SPI interface and 3.3V supply allows connection to most processors. Applications are hand held instruments and wearables.

MMS Electronics has available the new EA uniTFT050 display. This 800x480 pixel, 24bit, TFT display was introduced at Electronica 2016. The display uses object programming in combination with the uniTFTDesigner software. Objects can be placed, moved, rotated and deleted at any time. Font sets are stored directly in the display including Chinese characters. Powerful commands for elegant effects such as fading in and out, flying in, loss free rotation are integrated. Images can be embedded and MP3 sound files played. 7 Interfaces to the outside world: USB, 2 x SPI, 2 x RS-232 and 2 x I²C bus. These can be declared as masters to control external devices directly from the EA uniTFT050. Additionally the EA uniTFT050 is packed with 4 analogue inputs, 1 x PWM output and 16 digital I/O (expandable up to 125) to take on a wide range of control tasks. Even an analogue video input for a 3.3V camera (PAL, SeCAM or NTSC format) is included.
The EA uniTFT displays are available without touch-screen or with a PCAP or resistive touch-screen.
