Controller questionfrom a newbie
« on: August 09, 2017, 05:26:03 PM »
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  8)

To keep things simple the "Controller" or driver chip manages the display.

Take as an example the NHD-1.69-160128ASC3:

http://www.newhavendisplay.com/nhd169160128asc3-p-9288.html

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!
