Which LCD controller to use?

[ellboy]

Hello,

I would like to get a new LCD module with parallel interface which can be used with uGFX. As one can see uGFX supports a number of different controllers. Which supported controller does provide better software support and performance? Which one would be a better choose?

Regards

Hello ellboy and welcome to our community!

It really depends on your application. The best performance is delivered by the RA8875 as it provides hardware acceleration for drawing circles, lines etc. However, this is an industrial grade controller and therefore it's not easy to find cheap modules that come with it.

The most used and best supported drivers are the SSD1289 and SSD2119. The SSD1963 is used for displays with a higher resolution but it can be tricky to get it running as you have to manually enter the panel data (how the signals should look like). But as most suppliers give those values, it's still not too much of trouble.

To summarize: Go for an SSD1289 or SSD2119 if you're in the lower resolution segment and choose an SSD1963 for higher resolutions.

I hope that this answers your question. Feel free to ask any further ones.
