take a look at the various schematics available for tablet reference designs etc. etc. you want something like a SY7208 see http://hands.com/~lkcl/eoma/TABLET162_20121110.pdf page 7 and make sure it's providing enough current.
please for goodness sake read the next update when it comes out, please for god's sake don't go searching on digikey, pick the first random convenient IC and expect to be able to have what you design made up in even a small volume at anything approaching a reasonable cost. it's very very easy to design ultra-expensive products.
take a look at frida's LCDs, we have the advantage of being in touch directly with marco, the possibility of group buys, etc. etc. datasheets all here: http://rhombus-tech.net/suppliers/shenzen/frida_lcd/

Hello everyone!
If anyone if interested, I’ve updated the block diagram with new changes: http://george.the-petries.co.uk/shared-write-access/eoma/Block%20Diagram%20Z...
Any suggestions/corrections are appreciated. Thanks!
Do you have a chip picked out to provide 5V boost to the EOMA card yet? The AXP209 does not appear to provide it.
My plan for handheld computer was to use a TI brand LiPo charging IC and 5V boost. The AXP209 seems like a better idea than the TI charging solution since it has configurable regulator outputs and lower cost.
Also, I see you are not using SSD2828 for RGB to MIPI conversion anymore. This week I finished up a preliminary schematic for a SSD2828 testing/breakout board. I briefly started the layout and began to have second thoughts. It seems like too much work to incorporate it. I'm now looking for ~4 inch RGB LCD's instead.
