Dot Defect - A defect that affects a single "dot' or sub-pixel.

Two Adjacent Dots - Two adjacent dots in the horizontal direction are considered one dot.

Bright Dot Defect - Sub-pixel (red, green, or blue) is bright or visible and can always be seen on an all black background.

Dark Dot Defect - Sub-pixel (red, green, or blue) is dark and can always be seen on an all white background.

Linked Dot Defect - Defect that affects two adjacent sub-pixels. Vertically-linked dot defects are always the same color. Horizontally-linked dots are always or different color dots.

Visual Inspection Conditions

All displays must be inspected under the following conditions. Ambient lighting falling outside of the parameters. The use of magnification, temperature extremes and extreme viewing angles are not allowed in determining the acceptance or reject of any display.

Viewing distance: 35 to 50 centimeters or 13 to 20 inches.
Ambient illumination: 300 to 700 Lux (nominal 500 Lux)
Ambient temperature: 25° +5° Celsius (77° +9° Fahrenheit)
Viewing angle: Normal to the front surface. Off angle viewing is not allowed.

LCD Monitor Guidelines

The number of defects allowed is determined by the size and the dot density of the panel.

Bright dots (random)	3	4	4	4
Bright or Dark dots (two adjacent)	1	2	2	2
Dark dots (random)	3	4	4	4
Total Defects	6	8	8	8
Minimum Distance Between Defects

Dark to dark dots	5 mm	5 mm	5 mm	5 mm
