The DD-160128FC-2A is a solid little screen, at around 4.3cm (from corner to corner) it’s perfect for displaying information on small mobile robots, a little serial terminal screen for desktops, wrist mounted electronics and a whole bunch more. The only issue with the design of the screen is that it doesn’t come with any mount holes, leaving the only real option of mounting this to a case or project box with glue on the back (which makes it not reusable) or sandwiching the displays edges between two layers (which could prove difficult with only a few millimetres border).
The display boasts a bright back-light thanks to the use of OLED (organic light-emitting diode) which also keep the power consumption low (3.3V input) making this an awesome little display for mobile use when a power supply isn’t available. The colours are surprisingly deep and vibrant for such a small display and there is no visible flicker from the refresh rate. The 160×128 resolution is easily enough to display around 10 lines each with 18 characters on, alternatively it would look great displaying a camera video feed or a slideshow of pictures.
An EAGLE library was created for this OLED screen which includes pin descriptions and correct sizing for those wishing to create their own PCBs for projects using this display. It can be found here.
For those wishing to use this product in conjunction with an mbed (more info here) someone (simonb, over at the mbed community) has created a driver for the “Densitron DD-160128FC-1A”, this should work perfectly well with this newer module screen and all the source code and much more information is available through the mbed website – here. This is a great library which allows you full control over colour, fills, text, individual pixels and even the orientation of the screen.
If you’d prefer not to attempt creating your own PCB and all that pesky soldering, or are not very good at soldering I strongly advise buying the breakout board for this screen (this can be found at Farnell here), it’ll allow you to develop and play around with the board much easier and it’s only around £15.
Densitron also offer a bunch of other screens with a range of sizes, resolutions and prices and due to the ease of use of their products they seem to be an ideal for hobbyists, students and anyone looking to prototype a product quickly. Check out their entire range over at Farnell – http://uk.farnell.com/densitron/
Keep tuned for more projects using this, all will include schematics and source code.
