, 2013
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 TFT monitor panels used in
at panel 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 Pixel Policy explains the different types of pixel defects and denes acceptable defect levels for each type.
In order to qualify for repair or replacement under warranty, the number of pixel defects on a TFT monitor panel must
exceed these acceptable levels.
Pixels and Sub Pixel Denition
A pixel, or picture element, is composed of three sub pixels in the primary colors of red, green and blue. When all sub
pixels of pixel are lit, the three colored sub pixel together appear as a single white pixel. When all are dark, the three
colored sub pixels together appear as a single black pixel.
