looking for a bit LCD 12" to be used with FPGA
« on: August 30, 2013, 02:32:45 pm »
hi guys
i am looking for a bit LCD of 12" 1024x768x32 at least that could be driven by an FPGA about signals properly handled by the LVDS stuff. Anybody knows a good laptop's LCD to be used this way ?

Anybody knows if there is a kit about the LVDS stuff ?

regards

You have two options,
1. Generate the LVDS directly with the FPGA and run through an external driver to drive the display cable.
2. Generate RGB+syncs and use a LVDS converter to drive the display cable.

There are ebay sellers in china that will sell you 1x of almost any display. Consult panelook's parametric search to find a model number given your size and resolution.

Any kit around about these options ?

Thanks for that panelook website. Learn something new every day. :)

I am afraid of the LVDS converter ... very high frequency signals

There are some older 12" panels up to about 800x600 that have a parallel interface - these are really easy to drive via LVDS.

There is a parallel to LVDS add-on board for the Beagleboard, which may be a ready-made solution

1Kx768 LVDS direct from a FPGA like the Spartan6 that has serialiser support is probably not that hard - I'm sure makers of FPGAs with this stuff will have examples and appnotes

Bear in mind that at this sort of resolution, getting enougg memory with sufficient starts to become nontrivial unless you're doing simple non memory-bitmapped stuff
