Qt blank the display

[aabc]

I'm using Qt on embedded linux with Freescale i.MX53.
For some reason, after ~10 minutes without user interaction - Qt is calling for Kernel API that blank the display (The display is unblank after new user interaction). This phenomenon only happens when Qt application is running.

Did anyone encountered this phenomenon ?

Do you have a screen saver on your display ?
