Working with the Tab let PC
The screen resolution of your Tablet PC’s touchscree n is optimally set at the factory.
Current production technology canno t guarantee an absolutely fault-free screen display. A few
isolated constantly lit or unlit pixels may be present. T he maximum permitted n umber of such
faulty pixels is specified in the international standard ISO 9241-307 (Class II).
Example:
A screen with an HD resolution of 1280 x 1024 has 1366 x 768 = 1,310,720 pixels. Each
pixel consists of three subpixels (red, green and blue), so there are alm ost 3.9 million
subpixels in total. According to ISO 9241-307 (class II), a maximum of 3 light and 3
dark pixels and, in addition, 7 light or 13 dark subpixels or an equivalent mix (1 light
subpixel counts as 2 dark subpixels) are allowed to be defective.
