NEW PRODUCT – RGB backlight positive LCD 20×4 + extras [black on RGB]

Pt 101804

NEW PRODUCT – RGB backlight positive LCD 20×4 + extras [black on RGB]. To match our popular 16×2 RGB Character LCDs (http://www.adafruit.com/products/399 & http://www.adafruit.com/products/398) we’ve now added 20×4 LCDs! Get more text, with an RGB backlight. Both positive and negative type! This is a fancy upgrade to standard 20×4 LCDs, instead of just having blue and white, or red and black, this LCD has black characters on a full color RGB background! That means you can change the display background color to anything you want – red, green, blue, pink, white, purple yellow, teal, salmon, chartreuse. This LCD looks strikingly good in person. This LCD is the most daylight readable character LCD we have and is very beautiful and easy to read no matter what color/brightness you have for the backlight.

One nice thing about these LCDs is that they are an elegant upgrade, but you can use them in existing LCD projects and they’ll still work – just that only the red LED will be used (so it will appear black-on-red). The extra two pins (17 and 18) are for the green and blue LEDs. The LCD has resistors on board already so that you can drive it with 5V logic and the current draw will be ~40mA per LED (there are two LEDs, 20mA each). There’s a single LED backlight for the entire display, the image above showing 3 colors at once is a composite!

Comes with a single 20×4 RGB backlight LCD, 10K necessary contrast potentiometer and strip of header. Our tutorials and diagrams will have you up and running in no time!
