This article provides information on LCD display pixel guidelines for LCD panels on laptops and Dell flat panel monitors, understand what is a pixel or dot, how to identify a bright or dead pixel on your LCD Display and some answers to frequently asked questions.

LCD Display Pixel Guidelines

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.

The is premium within the industry, because it is guaranteed during the term of the limited hardware warranty to have zero pixels stuck in the "on" position — a factor that results in a bright dot on the display.

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.
