About the ST's Display Panel
• The ST's currently displayed data, its voltage
*1
and brightness setting each affect the intensity of Contouring. (i.e,
when some parts of the screen are brighter than others, creating a wavelike pattern)
• There are minute grid-points (dark and light) on the Display Panel's surface. This is part of the ST's design and not a
defect.
• Extended shadows, or "Crosstalk" may appear on the sides of screen images. This is normal for an LCD display.
• Sometimes the display area may look as if the display colors have changed. This is a common attribute of LCD's and
is not a defect.
• Displaying a single image for long periods can cause an afterimage to remain when the display is changed to another
screen.
To prevent this effect:
• Use the ST's "Stand-by Mode", which automatically turns the screen OFF when there is no input for a
specified period of time.
• Write "FFFh" to the System Data Area's “Screen Display Off” address
*2
to turn the screen display OFF when the
following actions are not performed for the user's designated period of time.
• Change Screen
• Touch Screen
• Alarm Display
• Do not display any single screen for a long period of time. Try to periodically change the screen display.
*1 If the ST's voltage is at the very low end of its allowable range, it may effect the intensity of contouring.
