How to define how long the backlight is switched on?

FAQ #101040

It's possible to extend the lifetime of the illumination by switching off the backlight during periods of inactivity.

 

 

Background

The display of the web panels is illuminated with a backlight. The lifetime of the backlight is limited. That doesn’t mean that the illumination will stop completely - there is a slow but continuous decrease of brightness. It’s possible to extend the lifetime of the illumination by switching off the backlight during periods of inactivity.

Windows CE offers build-in functions to switch off the backlight after a period of time without touching the screen. In details this means, if the screen is not touched within a predefined time, the backlight is switched off and the screen turns to dark. To reactivate the illumination you only need to touch the screen once again; then immediately the backlight is switched on once again.

Activating the automatic switch-off function of the backlight

  • Start the "Saia PCD® Web Panel Manager"

Remark
In Windows CE there is another possbility to control the backlight which will not work on Saia PCD® Web Panels: Don't use the properties window from the desktop (Display Properties). This will not work!
