How can i replace screen on Samsung S1070?

Hi,
My samsung S1070 got its lense bent when the kids used it at London Zoo. I straightened the lens but still not working. I got another identicle camera and need to change the screen over.
I have taken my camera apart but I can't seem to remove the screen. I have taken out the screws and have the screen loose from the camera, just attached by the flexible cable.

How can I unplug this cable?

Even if I wanted to change over just the lens, I have the same problem. There are two of these flat cables to unplug.

Please can anyone help??

many thanks

Andy
