All Akyga LCD monitors apply only flat panels in accordance to the fault class II defined by the ISO 13406-2 standard.

What does the ISO 13406-2 standard concerning pixel faults in LCD screen panels define?
This standard defines the type and quantity of possibly appearing pixel faults per 1 million pixels.

The norm distinguishes the TFT LCD panels into classes determining the quantity and kind of matrix defects.
These defects can but not must occur in particular TFT panel.
Their quantity and position are the basis for defining of warranty conditions for LCD monitors.
The values indicated below are maximal values for each class.

The particular fault types stand for:
Type 1 - completely white pixel appear
Type 2 - completely black pixel
Type 3 - subpixel (red, green, blue ore no pixel)

If faults occur side by side on a field of 5 in 5 pixels there applies following additional norm:

*A cluster is a field of 5 in 5 pixels.

How do the faults look like on the panel?
Below is demonstrated a fragment of panel together with fault examples:



One (full) pixel consists of three subpixels in red, green and blue colour.
Each subpixel is operated by one transistor.

How to calculate the permissible number of faults for a monitor?
The number of faults can be calculated from an appropriate proportion
(number of faults = number of faults according to the norm x number of pixels / 1 000 000) always adjusting upward. Below are presented calculations for class II panels. This is to notice that the resolution in the chart below is not the actually used resolution but so called natural resolution - this is a resolution, that results of the real number of pixel on the screen.
