Due to the manufacturing process, individual pixel errors cannot be excluded to 100 % and therefore do not constitute a
reduction in quality.

INFORMATION
A projective capacitive touch screen is built into the panel, with which
10-finger input, zoom and gesture functions can be implemented. Data
can be input using fingers, a project capacitive touch pen as well as
with thin gloves. The device must always be grounded to ensure stable
function of the touch screen. The touch function may still have to be
individually adapted to the respective environmental conditions.
