LCD Rant on LIVEdigitally
Posted by Jason Dunn in "ARTICLE" @ 06:00 AM
"Now what defines faulty in a TFT? Simply put: a single dot on screen known as a 'dead' or 'hot' pixel. In the LCD assembly process, the automated assembly lines pack together millions of transistors in a 'thin film', a very delicate process indeed. The fact that certain pixels get 'dislodged' or stuck can not be helped due to the microscopic nature of transistors. Once a pixel is either dislodged or stuck, you can consider it a gone case, there is no way to fix it. Unfortunately, most manufacturers do not discard such LCDs. In fact, some think it is perfectly acceptable for an LCD to have up to seven, (yes seven) dead pixels on a display! This means up to seven visible, dead, pixels, on your screen, all the time. Now I don't know how many of you think this is outrageous but I certainly cannot work on a TFT where I have to live with even a single black, white, red, green or yellow dot. It gets even worse: some LCDs get assembled perfectly. But they still might develop dead pixels over time! I use a lot of laptops at work, and have recently had some quite bad experiences. Let's start from the top..."
Wow, this guy has bad luck with dead pixels! I feel his pain though - there's nothing worse than finding a dead/stuck pixel on an LCD screen, because once you see it, you'll always know it's there. Sitting around me right now are five LCD screens, and thankfully none of them have bad pixels. That I can see at least. Ok, now I'm terrified... 8O
