5.2 Visual Inspection

Permanently unlit or lit pixels

The standard of production techniques today cannot guarantee an

absolutely faultfree screen display. A few isolated constant lit or unlit

pixels may be present. The maximum permitted number of pixels faults is

stipulated in the stringent international standard ISO-9241-302 (Class II).

Example: a 17" flat-screen monitor with a resolution of 1280 x 1024 has 1280

x 1024 = 1310720 pixels. Each pixel consists of three subpixels (red, green

and blue), so there are about 4 million dots in total. According to ISO-9241-

302 (Class II), a maximum of 6 pixels and 7 subpixels may be defective, i. e.

a total of 25 faulted dots. This corresponds to approx. 0.002 % of the entire

screen surface.
