Cleaning; Disposal; Pixel Defects On Screens - Medion AKOYA P54016 Mode D'emploi

Cleaning

You will be able to extend the useful life of the TFT monitor by the following measures:
Important!
No parts to be maintained or cleaned are located within the monitor casing.
 Always pull out the mains plug and all connecting cables before cleaning.
 Do not use any solvents, corrosive or gaseous cleaning substances .
 Clean the screen with a soft, fluff-free cloth.
 Pay attention that no drops of water remain on the TFT monitor. Water can cause long-lasting
discolouring.
 Do not subject the screen to either dazzling sunlight or to ultra-violet radiation.
 Please keep the packaging material and use this exclusively to transport the TFT monitor.

Pixel defects on screens

For active matrix TFTs with a resolution of 1920 x 1080 pixels, which are each made up of three sub-pixels (red,
green, blue), there are a total of approx. 6.2 million control transistors in use. Occasionally one or more pixels
can fail or become incorrectly controlled because of this very high number of transistors and the associated
extremely complex manufacturing processes used.
In the past, there were consistently a wide variety of approaches available for defining the permitted number of
pixel defects. However, these approaches were mostly very complicated and completely different from one
manufacturer to the next. In the handling of warranty issues for all of its display products, MEDION adheres
therefore to the strict and transparent requirements of the standard ISO 9241-307, class II, which has been briefly
summarised below.
The ISO standard ISO 9241-307 defines, amongst other things,
generally valid guidelines in relation to pixel defects. Pixel
defects are categorised into four classes of defect and three types
of defect. Every individual pixel consists of three sub-pixels, each
of which is assigned a basic colour (red, green, blue).
