I am using a TFT display with ssd1963 controller built-in and stm32f4 discovery board, and everything is working well except when writing to the display.
There is a significant increase in system noise and it is actually
audible on the codec output and also effecting my ADC readings.

All pins are configured correctly and as I mentioned display is working very well. 
I am driving the display controller from the stm32f4 with 150R resistors because I saw this used in a schematic for a dev board with a TFT. I assumed the resistors were used to terminate the tracks to help with track ringing and impedance, but perhaps they are used to limit current.   

Has anyone else seen problems with TFT displays and data pin noise?   

Would putting an array of transistor buffers between the micro and display help as long as the buffers where given it's own regulator to keep noise out of the main power supply?

With these kinds of projects making changes like this are not trivial so looking for possible suggestions before busting out the soldering iron


Question: use of verb "accord"
Answer: This meaning is closer to "given to". I'll edit when I figure out why. 

Edit: yeah, I have no clue why. This is a very dated meaning, but it still came to me immediately. It's passive, so it means "that is given to" here.
