DFRobot has an I2C 16×2 Arduino LCD with RGB Backlight Display which backlight can be modulated to the different backlight colours and the display effect is very brilliant. This RGB LCD backlight panel is its internal backlight component.

The RGB LCD backlight panel uses the RGB colour model, this is an industry colour standard that produces a wide variety of colours by varying three colour channels: red (R), green (G), and blue (B), a total of 16 million colours, nearly all colours that human vision can perceive.

The RGB LCD backlight board has a built-in common anode diode with the black edge at the pins facing up, the pins from left to right are red, power positive, green and blue. It can be used for both backlighting and LED indicators.
