AOC Monitors Panel Pixel Defect Policy
AOC strives to deliver the highest quality products. We use some of the industry's most advanced manufacturing
processes and practice stringent quality control. However, pixel or sub pixel defects on the Monitor panels used in
the monitors are sometimes unavoidable.
No manufacturer can guarantee that all panels will be free from pixel defects, but AOC guarantees that any
monitor with an unacceptable number of defects will be repaired or replaced under warranty. This notice explains
the different types of pixel defects and defines acceptable defect levels for each type. In order to qualify for repair
or replacement under warranty, the number of pixel defects on a Monitor panel must exceed these acceptable
levels. For example, no more than 0.0004% of the sub pixels on a monitor may be defective.
Furthermore, AOC sets even higher quality standards for certain types or combinations of pixel defects that are
more noticeable than others. This policy is valid worldwide.

Pixels and Sub pixels
A pixel, or picture element, is composed of three sub pixels in the primary colors of red, green and blue. Many
pixels together form an image. When all sub pixels of a pixel are lit, the three colored sub pixels together appear as
a single white pixel. When all are dark, the three colored sub pixels together appear as a single black pixel. Other
combinations of lit and dark sub pixels appear as single pixels of other colors.
Types of Pixel Defects
Pixel and sub pixel defects appear on the screen in different ways. There are two categories of pixel defects and
several types of sub pixel defects within each category.
Bright Dot Defects
Bright dot defects appear as pixels or sub pixels that are always lit or 'on'. That is, a bright dot is a sub-pixel that
stands out on the screen when the monitor displays a dark pattern. There are the types of bright dot defects.
One lit red, green or blue sub pixel.
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
