Using an LCD display panel (40-pin) with Raspberry PI 3

Mon Aug 22, 2016 4:42 pm

Hi, I'm new to Raspberry (but not to programming :) ) and I'm looking for an LCD panel to connect to it (something like this: https://www.lcdshop.it/display-e-scherm ... l3596.html). I have a Raspberry PI 3.
I don't want to use a full-fledged LCD display because I'd like to wrap the panel into a photoframe or similar.
Can I connect a 40-pin panel like the one I linked? Is it difficult for a raspberry noob? :)
Thanks

No you can't connect the display directly to the RPi. You will need a driver board to convert the screen output to HDMI.
Search ebay with the model number of the screen to see if a board is available.
Here is an example of a converter board. Note that this may not work with your screen: http://www.ebay.com/itm/HDMI-VGA-2AV-LV ... xyUgtTO8Sy
Unless specified otherwise my response is based on the latest and fully updated Raspbian Buster w/ Desktop OS.

From what I've seen of LCD displays, once you get past the 480x320 3.5" ones, you have to connect to HDMI rather than to the GPIO block. A Pi really struggles to get a refresh rate of more than 20 fps or so at 480x320 and beyond that, it's hopeless and you need the VC4 HDMI capabilities.
