The basic $9 (yes i know its a cheap-o) seven button screen I have when scrolling through numbers it blurs them horribly even with faster LCD library. I just want something that will be able to be readable at arms length away without squinting really. What TFT from 3.0"-5" is most widely used and also isnt super expensive? The 4d systems seem to be overkill and overpriced for my project. I just need a big screen without super high detail.
These ones on eBay? http://www.ebay.co.uk/itm/3-2-TFT-LCD-Module-Display-Touch-Screen-Panel-PCB-Adapter-SD-Slot-akr-/180866254803?pt=LH_DefaultDomain_0&hash=item2a1c7807d3
Having said that the documentation looks poor - I have had some of the 2.4" screens from them and they
work (3.3V logic only, 8 bit parallel mode only) You get SDsocket and touchscreen too...
