Vent Clearance
The
The vents for the lamp cavity are along the top and bottom edges of the display with the openings facing the rear. The vents for the inverter cavity are along the top and bottom faces of the display: four along the top surface and four along the bottom surface. Refer to the mechanical outline drawing in Figure 15 for vent locations.
Isolation/Air Gap
The display generates high voltage AC to drive the CCFL tubes. High voltage is present at numerous points on the backlight/inverter ECA which forms the rear surface of the display, so your application should not place metal too near the ECA. In the interests of both high voltage isolation and airflow for cooling, it is recommended that an air gap of
.197" (5 mm) or greater be maintained behind the display.
Ambient Light Sensor Clearance
Two backlight dimming modes utilize automatic brightness control (ABC). 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
Cable Length
Due to the high frequencies present on the video interface, unterminated video cable lengths of more than two feet (600 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
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.
