How many dead pixels are allowed on Samsung TFT Monitors?
Dead/black dot defect which does not exceed more than 7 dots are within factory specification. Repair is needed if exceed more than 7 dots.
TFT covers the outer layer of LCD panels that either allows or block the backlight to pass through the LCD screen to generate an image.
In case of Dead Pixel, this refers to Inactive TFT which does not respond to voltage changes hence no light passes through it, causing black dot or otherwise termed as DEAD PIXEL.
