I'm trying to build a HDMI decoder board for a 4in 480x800 IPS display. I found an HDMI decoder board on adafruit(https://www.adafruit.com/product/2218) which says it works for most 40pin TTL displays.
The display I'm intending to use has 51 pins and says it has an RGB/MCU interface.
I'm trying to look at the schematic and see if I can modify it and make a board that accepts the additional pins of my display but I'm not sure what the difference is between MCU and TTL?
I know the chip used on the adafruit decoder board (TFP401) supports both screens since I have an off-the-shelf 4in IPS display that uses that same chip.
Here is the datasheet of the display I plan to use: https://www.scribd.com/document/383775532/4in-IPS-display
