Is there any application enable me to lock screen without turning off display

[yccheok]

Hello all,

I just purchase a Nexus S.

Currently, to lock screen, I need to

1) Press the power button.
2) Screen locked.
3) Display turned off.

To unlock screen, I need to

1) Press the power button to make screen visible.
2) Slide the touch screen to unlock.

Is there any way I can?

1) Press a button to lock the screen.
2) The screen remains visible, but get much less bright to preserve power.

1) Slide the touch screen to unlock.
2) Brightness of the screen back to normal.

Thanks

See below threads which may help you. As I posted in the second thread, leaving the screen on uses a lot of battery power, so I don't recommend that option. However, Widget Locker allows you to wake the phone using the trackball or other buttons instead of the power button, and it allows you to activate lock screen from the pull down status bar (in addition to many other cool features).
