Considerations about the Screen

This paragraph offers key considerations regarding the use of the colour
screen, taken from the specifications of the manufacturer.
In the TFT display, the user may find pixels that do not light up or pixels that are
permanently lit. This should not be regarded as a defect in the TFT. In accordance with
the manufacturer quality standard, 9 pixels with these characteristics are considered
admissible.
Pixels which are not detected when the distance from the surface of the TFT
screen to the human eye is greater than 35 cm, with a viewing angle of 90º between the
eye and the screen should not be considered manufacturing defects either.
It is advisable a viewing angle of 15º in the 6.00 o'clock direction in orden to
obtain the optimum visualization of the screen. See following figure.
