Dead Pixels

Can someone explain to me why there is a problem with dead pixels for PC TFT screens and not for laptop TFT screens?, at least i've never heard of a problem with dead pixels and laptops. Is it something to do with the technologies they use?

I'm looking to buy a new PC and a flatscreen but if this dead pixel thing is going to be such a problem (I do a lot of graphics work) maybe I should get a laptop.

What do you guys think?

CTX gaurantees zero dead pixels with their S530 and S730 click here click here

Otherwise the EU specs. allow a certain number of dead pixels due to the difficulty in manufacturing perfect screens.

When I went shopping for a tft in Comet I got a verbal assurance from the manager that if the monitor had even one dead pixel then it would be replaced or a refund given, this guarantee was for three months. How much faith can you put in verbal guarantees ? I dont know. I bought a display model (Acer AL712 17") with a 10% discount the only thing missing was the box, at least when you buy a display model you can be absolutely sure that there are no dead pixels.

The CTX guarantee will not be lifetime guarantee as they only have an entire life expectancy of 10,000 hours.

TFTs on laptops and desktops use the same technology, and suffer from the same dead pixel issue. It's all down to how individual suppliers treat the issue.

Remember that on the whole laptop displays are smaller than the unit you use at home so have a smaller number of pixels. There is still the possibilty that they can have pixel failure. I work for a computer company and I say that in the last 18 months I have not seen one TFT that has had a pixel failure.

The CTX guarantee is for 99 days if I remember rightly.
