LCD Television Defect Policy
Due to the cost of producing LCD panels, panel manufacturers have set limits as to how many
defective dots (or sub-pixels) are deemed to be acceptable for a standard LCD panel. The goal in
setting such limits is to maintain a reasonable price of the panel while minimising distraction from
defective dots.
What is a bright and a Dark Dot?
A pixel(picture element) consists of noe red and one green and one blue dot or sub-pixel. A
standard 38.1cm(15") LCD panel with a resolution of 1024 x 768 pixels has a total of 786,432
pixels or 2,359,296 dots, while the 50.8cm(20") has 1.44 million dots.
Each dot is driven by an individual transistor. If a transistor becomes defective, the corresponding
dot may be permanently lit (a bright dot) or may totally defect free would lead to a much higher
cost of manufacture.

The specifications for the number of defects that are deemed to be acceptable for each size of
LCD panel are:
