Yes PM is enabled by default so LCD will go to power saving mode in
case it doesn't detect any activity.

To disable PM completely apply this patch
http://gitorious.org/rowboat/vendor-ti-am3517evm/commit/0fc20338c811a1678a80cf82f25f090a29a5c2f8

You can also set Screen Time out to some larger value(default is 1 or
2 minutes I guess) from Settings -> Display -> Screen Time Out.
