AOC Pixel Policy

ISO 9241-307 Class 1

July 25

, 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

flat 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 defines 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 Definition

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.

Types of Pixel Defects

• Bright Dot Defects: the monitor displays a dark pattern, sub pixels or pixels are always lit or “on”

• Black Dot Defects: the monitor displays a light pattern, sub pixels or pixels are always dark or “off”.
