laptop screen

Hi! I have a Toshiba Satellite 2775XDVD laptop . I have had it since year 2000. I keep it on for long periods of time every day. I have a question: What is best for the screen: To keep it on all the time (with a screen saver) or to allow it to automatically turn off after a certain time of inactivity?

I mean, let's say I use the computer in an interrupted manner throughout the day, so let's say that on an average day the screen would go off automatically 10 to 20 times... Would going on and off shorten its life in any way? Is is better to just keep it on all the time and run a screen saver? Or would it be better to make it go off during the time (often hours) that I'm not using the computer?

That is my main question.

However, I'm also just curious to know one more thing: Is it important to have a screen saver on a laptop screen? I know that with regular screens (for a desktop... not a LCD), running the screen without a screen saver for long times without anything changing on the display, is bad for the screen. Is that also true for a laptop screen?

I would appreciate any feedback.
Thank you!!

basically it is better to keep it on for long periods of time, and off for long periods of time, but it is not good to have it come on and off every 5 minutes or so.
