Policy on defective pixels
Due to the complexity of the technology used in the manufacture of LCD, TFT and LED screens, it is possible
that some of the pixels that make up the screen may be defective. While it is desirable for all the pixels to
function correctly, this is not always possible from a production perspective. For this reason, Iotecnia, S.L. certi
es that its LED TV products meet the criteria of admissible defect described herein and certi es that its LED TV
screens are class A.
Defective pixels
Bright pixel (max.)
Dark pixel (max.)
Maximum permitted sum of pixels
Double adjacent pixels (max.)
If an LED TV screen has dark or bright pixels, this is only considered to be a fault by Iotecnia, S.L. when the ran-
ges established herein for an LED panel to be considered defective are exceeded, thereby allowing Iotecnia, S.L.
to manage the replacement or warranty of the panel due to a product non-conformance. As a rule and except for
limited exceptions, Iotecnia, S.L. considered an LED TV product to be faulty when it has a considerable number
of permanently bright or dark pixels. As a reference, an LCD/LED panel has more than 1 million pixels and a
single defective pixel is therefore not considered to constitute a lack of conformance and cannot be catalogued
as a fault, as this circumstance will not a ect the correct functioning of the product.
Bright pixel
Dark pixel
Double adjacent bright
Therefore, if an LED screen meets the above criteria, it cannot be changed or repaired as this is not considered
to be a lack of product conformance and cannot be catalogues as a defect or fault.
