I just want to know whether dead pixel will become more and more when LCD is getting old.

I am from HK. [/QUOTE
When you see the LCD without the dead pixel,it can't appear awhile,but it appears the dead pixel on one day.
The dead pixel in different light can't see it,perhaps the dead pixel because different surrounding.

I have not the problem,so I could speak the mistake,you should buy a new LCD,I only give you a suggestion.
