LCD displays are made up of a set number of pixels. Each pixel is made up of red, blue and green sub-pixels.  When a subpixel is fixed in an unchanging state, the visible result is a tiny black, white, or coloured spot that displays on the screen. There are generally two types of subpixel defects, bright and dark/dead subpixel defects.

A bright pixel defect is where a subpixel remains permanently lit resulting in a white, or coloured dot on a black background. Bright pixels can be white, red, blue, or green and can be identified on a black background.

A dark or dead pixel defect is where a subpixel remains permanently unlit resulting in a black dot on a white background. Dead pixels can be identified on any background colour except on a black background.

Understanding our pixel policy

The table below shows the allowable number of pixel defects.


Type of pixel defect

Number of pixel defects

Bright pixels

2 or less

Dark or dead pixels

5 or less

Total combined bright or dark/dead pixels

5 or less


NOTE: only fixed subpixels or dots (bright or dark) visible to the naked eye at normal viewing distance are eligible for replacement.
