LCD Display Pixel Policy

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 1 to 5 fixed sub-pixel is considered normal and within industry standards.
