Og selve authoren til den linkede artikel's kommentar:
As the author of the linked article I just wanted to clarify a few things...
First off, I went way out of my way not to criticize the system or compare it to the DS for any subjective or 'luck of the draw' failure. Some people have dead pixels, some don't. I didn't even mention it in the article.
What I wanted to draw attention to were the design flaws, the silly, stupid or ridiculous decisions Sony made to squeeze their uber-sexy tech into the PSP as it is today.
Så meget for de døde pixels i den nyhed...
#2: Dem der nævner døde pixels i denne tråd og jeg quoter korrekt:
I have a PSP and it has 5 dead pixels 2 are noticable and 3 are around the edges of the screen. When the unit is turning on and/or has a black screen you can see them but once you are playing a game you dont even know they are there. Most companys have a dead pixel policy. When I bought my laptop Dell said they would not replace a screen unless it had more then 5(I think) any way. Its just like someone else said "its the nature of the beast". I would rather have a PSP with dead pixels then no PSP.
Overskriften var endda et spørgsmål, ikke en konklusion...
#3: Jeg vælger at Quote igen:
I have no PSP but i do a heck of a lot of reading. I have not heard of imposing gmaeplay hindering on behalf of dead pixels so just play your games or watch movies and if just kills you then try to find the means to get a replacement. Most people are happy even with a few dead pixels.

Sony is actualy being very good about the whole dead pixel thing. Even if you buy a $2000 lcd you can't return it unless there is seven or eight dead pixels. The exeption is samsung, thier new warrentee is that they will replace any monitor with any dead pixels at all. Sayin gthat the psp shouldnt have any dead pixel's at all is just ignorant. There is no way to control wheather or not you get a dead pixel, every device with an lcd may have them.

Any LCD based screen can develop dead or stuck pixels over time, each pixel is made from 3 sub-pixels which in turn are controlled by individual transistors. Even if a panel/screen is perfect at time of manufacture these transistors can fail just like anything else over time.

There is a lot of misleading information being promoted these days about dead pixels, and I'll clarify what they are below.
The types of defect can be summarised as below
1
Complete pixel constantly illuminated (white spot). This is a stuck pixel
2 Complete pixel not illuminated (black spot). This is a dead pixel.
3 One or two sub pixels constantly on or off or intermittent fault. May blink or show a pixel as a basis colour (Red, Blue, Green, Cyan, Magenta or Yellow). These are sub-pixel faults.
This is what a TFT manufacturer told me
"Even with the high precision manufacturing processes that are used, manufacturers cannot guarantee that all will operate correctly, with the result that some non-operational pixels may be noticeable under certain viewing conditions."
Igen, som det nævnes er ingen af de døde pixels i denne nyhed til besvær for author.
#4: Sjovt, jeg er nu støt på en eller flere linier med teksten : You will find that with any product that has a colour lcd/tft screen. eller noget i den retning.
#5: Quoted:
Technically it's damaged. I had the same problem with an Archos AV320 MP3/4 player I got from Ebuyer. I sent it back and they replaced it no problem.
It's a fairly commonish fault with LCD screens in general..........annoying too.
Problemet i denne tråd er ikke en død pixel, men støv under skærmen, de har alle bestilt fra den samme sælger...
Bottomline:
Døde pixels stinker, men de er svære at undgå chancen for at "blive ramt" er stadig 0,1% bare sørg for at bestille fra en "thrustworthy" hjemmeside. Så skulle det ikke være noget problem. Forresten alle disse "pixel" fejl, kunne ligeså godt have fundet sted på en DS da den også er TFT/LCD...
