dead pixels
Full Definition & Technical Explanation
A dead pixel is a defective pixel that stays off, appearing as a black dot on bright content. It results from a failed transistor rather than the display's normal operation.
Unlike a stuck pixel, which is stuck on one colour, dead pixels cannot be fixed by pixel-refreshing tools.
