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.
