Backlight Bleeding is just pressure on the panel. Pressure is at its highest straight from the factory. With time and use, and also the heat generated through use, the panel can loosen over time, thus relieving the pressure spots and therefore reducing the backlight bleed.

A: The typical rated life of a CCFL backlight is 20,000 to 40,000 hours. When used in LCD applications such as laptops you should expect between 1 and 3 years of use from most manufacturers, depending on how much use the unit gets. Q: What makes your lamps better than others available?

What is the life expectancy of a regular LCD backlight?
A couple of questions: – What is the life expectancy of a regular LCD backlight? My HP w2207 currently has around 9,400 hours. Though I’m not 100% sure but I think it’s starting to dim just a bit, but then again it could be placebo.
What’s the life expectancy of a CCFL led?
CCFLS dim significantly with time. Not sure about LED decline, but lifespans are similar AFAIK. I have been measuring my NEC 2490. At 12000 hours it is just about exactly half as bright as when new. If another 12000 hours cuts it by half again, it would probably be done for most people.
