Question about the exposed pins on I2C RGB Backlight LCD 16x2 Display Module for Arduino

I'm reading the tutorial here: https://wiki.dfrobot.com/_SKU_DFR0374__SKU_DFR0936_LCD_Keypad_Shield_V2.0

 

I have question about the exposed pins on this shield.

 

For example, in the Board Overview section, what does “D6 + -” mean. 

 

I assume D6 is for pin D6 on the arduino. What is the “+” and “-” pins. My guess is that is power / ground?

I tested this out and the “+” and “-” do appear to represent power and ground respectively.
