IMHO, the ONLY good thing about LCD is the fact that it DOESNT suffer burn in.

 

LCD panels should be fine as they have low power flourescent tubes as the light source and run very cool.

 

LCD projectors have Metal Halide lamps that run VERY hot and age far too quickly but even then the LCD doesnt suffer burn in.

 

CRT will always give the best image but can suffer from burning, however in Grahams application where he has his own intranet running ASP's he could code them to to use different layouts every 15 minutes or so and avoid burn even on CRT's.

I did a quick search after my last post and found these…they both contradict each other!

Prevent Screen 'Burn-in'.

Remember this about CRTs? Well it still holds true for LCD screens. Failure to turn off or reduce the screen brightness can cause screen 'burn-in'. This is a permanent condition so be careful. If a fixed pattern is continuously displayed over a long period of time, certain LCD pixels can overheat resulting in image 'burn-in'.

Prevent screen burn in by:

--Turning off screen power when not in use.

--Changing the screen pattern at different intervals.

--Reducing the brightness level to darken screen.

The Life Of a Display

The life of each unit differs depending on how often it is used. The one factor that is most common on CRTs, showing the wear and tear of the unit, is screen burn. This is where the images that are on the screen in the same place all the time actually burn onto the phosphorous coating of the picture tube. Once screen burn has occurred, there is no way to remove it from the screen, On the other hand, LCD panels are made with liquid crystal, which constantly moves around the backlit screen to create the picture. Because of this process, an LCD unit will never experience screen burn. After extended use, the backlighting brightness on the LCD screen will decrease and a new lamp will need to be install. But replacing a lamp is less expensive than replacing a CRT tube that has screen burn.
