Controller question from a newbie

Hi All,
I'm new to this forum, and topic...in fact have never used a display.

Simple question: i see all these displays listing a "controller". Is this controller embedded in the display module? Or is it the controller that one is supposed to use to talk to the display?

I have a design with a PIC24F, and I would like to use a SPI protocol to talk to either an LCD or an OLED display.

  Welcome to the forum :)
  
  To keep things simple the "Controller" or driver chip manages the display.
  
  Take as an example the NHD-1.69-160128ASC3: https://newhavendisplay.com/1-69-inch-full-color-oled-serial-interface-module/ 
  
  This display utilizes the SEPS525 controller and you will communicate via 4-wire SPI to your MCU.
  
  The controller or driver chip is bonded onto the displays cable via a COF (Chip-On-Film) process.
  
  Hope this helps!
