Ambient Light Sensor Clearance
Two backlight dimming modes utilize automatic brightness control. If the display is to be
operated in either of these modes, the ambient light sensor located on the front bezel
must be unobstructed. If the sensor is placed behind the same protective window as the
display active (viewing) area, the sensor operation may be affected due to light scattering
and reflections from display-generated light coupling to the sensor via the window.
Cable Length
Due to the high frequencies present on the video interface, unterminated video cable
lengths of more than 12 inches (300 mm) are discouraged.
Cleaning
Care should be taken to minimize scratching. Clean the display front with a dry, soft
cloth such as a professional photographic lens cleaner. Disposable cleaning cloths are
recommended to minimize the risk of inadvertently scratching the display with particles
embedded in a re-used cloth. Particular care should be taken when cleaning displays with
polarizers or anti-glare and anti-reflective films. These films may delaminate if exposed
to certain chemicals.
Avoiding Image Retention
Image retention may occur when a fixed pattern is displayed for a long time. Use a
screen saver or image inversion to avoid image retention on the display.
