That means you can change the character display colors to anything you want - red, green, blue, pink, white, purple yellow, teal, salmon, chartreuse. This LCD looks strikingly good in person\u003cbr\u003e\u003cbr\u003eOne 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 red-on-black). 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!\u003cbr\u003e\u003cbr\u003eComes with a single 20x4 RGB backlight LCD, 10K necessary contrast potentiometer and strip of header.\u003c\/p\u003e\u003cp\u003eFor more information, check out our detailed step-by-step tutorial for both Arduino \u0026amp; CircuitPython\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cul\u003e\n\u003cli\u003e20 characters wide, 4 rows\u003c\/li\u003e\n\u003cli\u003eMulti-color text on dark background\u003c\/li\u003e\n\u003cli\u003eConnection port is 0.1\" pitch, single row for easy breadboarding and wiring\u003c\/li\u003e\n\u003cli\u003ePins are documented on the back of the LCD to assist in wiring it up\u003c\/li\u003e\n\u003cli\u003eSingle RGB LED backlight included can be dimmed easily with a resistor or PWM and uses much less power than LCD with EL (electroluminescent) backlights\u003c\/li\u003e\n\u003cli\u003eCan be fully controlled with only 6 digital lines!
