Regarding "dead pixels"

The easy explanation: Wacom's pen displays come with one of the industry's best reputations for quality, and each interactive pen display LCD panel is produced under very stringent quality standards. Although production techniques cannot guarantee an absolutely perfect LCD panel, Wacom does guarantee that our panels are compliant with ISO-13406-2 Class II standard.

The details: The term "dead pixel" is often used in regards to a dot on the screen that is stuck in one color. A pixel is made up of three sub-pixels that are red, green and blue. When any one of these sub-pixels is defective, this can result in a colored dot on the screen.

ISO-13406-2 (an ISO standard for defining pixel defects) outlines three types of defective pixels:

• type 1 = a hot pixel: (white dot) This situation occurs when all three sub-pixels are always on. (Class II allows 2 defects per million pixels)
• type 2 = a dead pixel: (black dot) This situation occus when all three sub-pixels are always off. (Class II allows 2 defects per million pixels)
• type 3 = a stuck pixel: (red, blue or green) This situation occurs when one or two of the sub-pixels are always on or always off. Stuck pixels may occur after our quality checks, and are known to disappear. There are several methods that MAY fix a stuck sub-pixel, but none of these methods have been tested by Wacom. Wacom will not be liable for any damage that may occur in attempting these methods, and such damage will not be covered under this product's 1-year warranty. Depending on the method of repair, the product warranty may become void. (Class II allows 5 defects per million pixels)

Please contact Wacom if you have further questions regarding this policy.
