ISO-9241-307:2008 guidelines for pixel defects

LCD displays are made up of a set number of pixels and each pixel is made from 3 sub pixels; one Red, one Blue and one Green. Every sub-pixel is addressed by its own transistor and so the manufacture of a glass substrate is very complex. Due to the nature of the manufacturing process, occasional defects can occur. Pixel defects or failures cannot be fixed or repaired and can happen at any stage in the LCD’s life.

To regulate the acceptability of defects and to protect the end user, ISO have created a standard for manufacturers to follow. ISO-9241-307:2008 recommends how many defaults are acceptable in a display before it should be replaced, within the terms & conditions of warranty.

All reputable manufacturers conform to and support the ISO ISO-9241-307: 2008 standard.

Pixel defaults

The table below shows the allowable number of malfunctioning pixels that are acceptable per 1(one) million pixels in the TFT/LCD matrix.

Any or all of the following:

1(one) full bright (“stuck on white”) pixel

1 (one) full dark (“stuck off”) pixel

2 (two) single or double bright or dark sub-pixels

3 to 5 (three to five ) “stuck on” or “stuck off” sub-pixels (depending on the number of each)


The above is relevant to Class I LCD panels.
