How to set LCD self-refresh mode for IMX25

We use imx25 internal LCD controller and shared LPDDR, which occupy about 45M bandwith.

 

How to reduce the bandwith occupied by LCDC?

 

Does LCDC self-reflesh mode benefit it? If so, how to change to self-refresh mode?

 

I set self-refresh mode in LCDC, but screen becomes white. I wonder whether there is others need modify?
