Evaluation of visual range
Failure of Pixel
A image point (Pixel) consist 3 sub pixel with basic colour red, green and blue.
The physical dimension of pixel (also called pixel pitch) differs depending on
the model (look at the data sheet for more information). If a pixel failure is
larger than 1/2 pixel, it counts as pixel failure according to definition. 3 kinds
of pixel failures are differentiated:
)
Permanently bright pixel.
•
The bright pixel is permanently and with constant size at black testing
image.
)
Permanent dark pixel.
•
The pixel appears permanently dark and constant size at red, green and
blue testing image.
)
Two pixels lying next to each other.
•
Two directly bordering pixels show a defect.
)
Acceptable number of dot defects according to ISO 9241 for Class II.
(See table „Overview Acceptable Total Number of Dot Defects“)
Pollutions
By the production process and handling of the displays occurs kinds of
pollution in range of vision. It applies to inclusions, blistering, depressions,
marks, scratch. The following tolerance limits is specified for bonded glass
surfaces and optional touch surfaces (panel size to 55“):
Tolerance limits for bonded glass surfaces:
KIND OF POLLUTION CRITICAL VALUE
Inclusions / Marks 0,5 < D ≤ 1,2 mm, N ≤ 16
Depressions / Blistering 0,3 < D ≤ 1,2 mm, N ≤ 16
Scratch / Lints 0,15 < W ≤ 0,25 mm, 0,3 < L ≤ 10,0 mm, N ≤ 10
Tolerance limits for optional touch surfaces:
POLLUTION CATEGORY CRITICAL VALUE
Inclusions / Marks D ≤ 1,5 mm
Depressions / Blistering D ≤ 1,5 mm
Scratch / Lints W ≤ 0,25 mm, L ≤ 15,0 mm
ACCEPTABLE TOTAL
NUMBER [G] OF DEFECTS
CRITICAL VALUE
Panel size to 55“ N ≤ 8, G ≤ 12
Panel size from 56“ to 65“ N ≤ 9, G ≤ 14
Panel size from 66“ to 70“ N ≤ 11, G ≤ 15
Panel size from 71“ to 82“ N ≤ 14, G ≤ 18
Panel size from 83“ to 110“ N ≤ 16, G ≤ 24
D = diameter, L = length, W = width, N = number of pollution of a category , G = total number of
mechanical defects or surface pollutions
