Each Pixel is made up of a red, green and blue sub-pixel. When a sub-pixel is fixed in an unchanging state, the visible result is a tiny black, white or colored spot that appears on the screen. There are generally two types of sub-pixel defects namely bright and dark sub-pixel defects. A sub-pixel defect is also referred to as a dot defect.
Bright Sub-Pixel Defects: A sub-pixel remains permanently lit, resulting in a white or colored dot on a black background.
Dark Sub-Pixel Defects: A sub-pixel remains permanently unlit, resulting in a black or colored dot on a white background.
During LCD manufacturing process, it is not uncommon for one or more sub-pixels to become fixed in an unchanging state. A display with a 1 to 5 fixed sub-pixel is considered normal and within industry standards.
